    PEOPLE v. SUAREZ
    S105876
    Opinion of the Court by Liu, J.
    After this case was transferred from Placer County to
    Napa County, a jury found defendant Arturo Juarez Suarez
    guilty of the first degree murders of José Martinez, Juan
    Martinez, J.M., and A.M. (Pen. Code, § 187, subd. (a)) and found
    true the allegations that he personally used a firearm in the
    murders of José and Juan (id. § 12022.53, subd. (d)) and that he
    personally used a deadly and dangerous weapon in the murders
    of J.M. and A.M. (id. § 12022, subd. (b)(1)). (All undesignated
    statutory references are to the Penal Code.) The jury found true
    the special circumstances that he committed these murders
    while lying in wait (§ 190.2, former subd. (a)(15)) and that he
    had been convicted of more than one offense of murder in the
    first or second degree (§ 190.2, subd. (a)(3)). The jury also found
    him guilty of forcible rape (§ 261, subd. (a)(2)), unlawful
    penetration by a foreign object (§ 289, subd. (a)), and kidnapping
    to commit rape (§ 209, subd. (b)(1)) of Y.M., and the jury found
    true the enhancement allegations for those offenses. Following
    the penalty phase, the jury returned a verdict of death. The trial
    court sentenced him to death. This appeal is automatic.
    (§ 1239, subd. (b).) We affirm the judgment.
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    I. FACTS
    A. Guilt Phase
    1. Prosecution Case
    a. Before the murders
    Arturo Juarez Suarez (Juarez) was a seasonal worker at
    the Parnell Ranch in Auburn in 1998. He lived in a trailer on
    the ranch and worked six days a week, typically taking Sundays
    off. He was married to Maria Isabel Juarez de Martinez (Isabel),
    and he was friends with her brothers José and Juan Martinez,
    all of whom had grown up in the same town in Mexico.
    José and his wife Y.M. lived in Galt with their five-year-
    old son, J.M., and three-year-old daughter, A.M. Juan also lived
    with them. Juarez often spent holidays and weekends with the
    family. He had a good relationship with J.M. and A.M.
    Y.M. testified that Juarez made her uncomfortable on two
    occasions, a few years before the capital crimes. One time, he
    grabbed her waist, she told him to let her go, he said he was not
    going to do anything, and he let her go. She slapped his face,
    and he told her not to hit him. Another time, he touched her
    ribs and her neck, and she told him to leave her alone. She told
    José about one of these occasions, and it caused some problems
    that were ultimately resolved.
    On July 4, 1998, José, Y.M., J.M., A.M., and Juan visited
    San Francisco without telling Juarez. When they returned,
    Juarez and his friend Ernesto Orozco were at the Martinezes’
    home. Juarez and Orozco spent the night there. Y.M. thought
    Juarez seemed upset when they said that they had not been able
    to call him before they had left for San Francisco that day.
    Orozco testified that he did not notice any problems, but on the
    drive there, he commented that the Parnell Ranch seemed like
    2
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    a nice place to live, and Juarez replied, “You’re way off. One can
    go crazy here by oneself.”
    Before leaving, Juarez made plans with José for the next
    weekend. Y.M. testified that her family planned to pick him up
    from the Parnell Ranch on Sunday, July 12 and give him their
    car to attend an immigration appointment on Monday, July 13.
    Juarez told his boss, Jack Parnell, that he planned to work on
    July 12 and take off July 13.
    b. July 12, 1998
    At 4:00 or 4:30 p.m. on July 12, José, Y.M., J.M., A.M., and
    Juan arrived at the Parnell Ranch. José wore a watch, Juan
    wore gold chains, and both carried wallets. Y.M. wore green
    shorts, a white shirt, and tennis shoes.
    When they arrived, they did not see Juarez. Y.M. went to
    his trailer to retrieve some soap to wash their car. As she
    returned to the car, she saw Juarez and José walking together
    toward it. She did not see Juan. Before washing the car, José
    needed to fix an issue with the car’s battery, and Juarez gave
    him a knife to assist. While José fixed the issue, Juarez left.
    When Juarez returned, he asked José to accompany him, which
    José did. Y.M. finished washing the car, went toward the trailer,
    and saw Juarez and José standing in the field.
    Juarez returned and asked Y.M. for the car keys, which
    she gave him. He went into his trailer, changed his pants, and
    asked her if she wanted anything from the store. She requested
    chips and a tea drink. Around this time, she noticed a rifle
    “standing there,” although she did not recall its precise location.
    Once he left, she walked around the ranch with her children for
    an hour and a half.
    3
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Juarez returned with chips, a tea drink, and beer. Y.M.
    asked where José and Juan were, and Juarez said that they
    were cleaning and cutting a deer that he had killed. Juarez
    asked her to cut some aluminum foil for the deer meat and said
    that he was going back to the deer. After cutting some foil, Y.M.
    sat in a chair outside the trailer. J.M. and A.M. played
    Nintendo, which Juarez had turned on for them, inside the
    trailer, and later came outside.
    Suddenly, Juarez put a rope around Y.M.’s neck, dragged
    her to the trailer, and kicked her. Her children cried; J.M.
    yelled, “Don’t hit my mommy,” and A.M. hugged J.M. Juarez
    shouted at J.M. to shut up. Y.M. lost consciousness.
    Inside the trailer, Juarez put a chain around Y.M.’s neck,
    tied her wrists behind her back, and tied her feet. When she
    regained consciousness, Y.M. was lying on the floor on her back.
    He cut her shorts and underwear with scissors, exposing her
    private parts, and he unzipped his pants. He put his fingers in
    her anus and his penis in her vagina. He said, “Since you didn’t
    want to willingly, now you’re gonna get fucked up.” She
    screamed for her husband. She did not hear her children at this
    time.
    Juarez tied Y.M. to something before leaving and coming
    back. She lapsed in and out of consciousness. He told her not
    to move too much or else she would get strangled. He put a
    handkerchief around her mouth, using gray tape; turned on the
    radio loud; and left. She lost consciousness. Eventually, she
    untied herself and left, leaving behind a tennis shoe and taking
    a knife to defend herself. She did not turn off the radio. She ran
    to Dorothy Parnell’s home, located on the ranch. Dorothy let her
    inside and called 911 at 9:15 p.m.
    4
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Jack and his son Jacob Parnell testified about that day. In
    the late morning or the afternoon, Jack told Juarez to clean an
    area near a barn on the ranch, and Juarez seemed abrupt, which
    was out of character. Around 5:00 p.m., Jack saw Juarez driving
    the Martinezes’ car much faster than usual. Around 6:30 or 7:00
    p.m., Jacob saw Y.M. and her children walking around the
    ranch. Between 7:15 and 7:30 p.m., Jacob saw Juarez driving a
    tractor with a trailer. Also, sometime in the days or weeks
    before that day, Jack saw Juarez coming from a target range
    area on the ranch and carrying a small caliber rifle, which he
    had not seen him carry before.
    c. The investigation
    When law enforcement officers arrived at the Parnell
    Ranch, Y.M. was hysterical. She wore a long shirt that had
    blood on it, a bandanna around her neck, and beige underwear
    that Dorothy had given her. She had a sock and a tennis shoe
    on her left foot, and a sock and a cord tied around her ankle on
    her right foot. She had blue-green underwear, with its crotch
    area cut, wrapped around her waist. She had rope marks
    around her ankles, wrists, and throat, and duct tape in her hair
    and wrapped around her neck. Her face and lip were swollen,
    and she had dried blood in her mouth, blood coming out of her
    right ear, and abrasions, bruises, and discoloration around her
    eyes. That night, she repeated “Arturo bad” and described his
    attack.
    Around 9:30 p.m., Deputy Mark Reed and Deputy Kurt
    Walker entered Juarez’s trailer to look for him. He was not
    there. Deputy Reed located and seized a .22-caliber rifle and a
    .30-06 rifle. The .22-caliber rifle was loaded, and there was
    ammunition for the .30-06 rifle in the trailer. Around 11:45
    5
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    p.m., Detective William Summers and Deputy Randy Owens
    entered Juarez’s trailer in an effort to locate identifying
    information.
    The following day, Y.M. returned to the Parnell Ranch and
    noticed, in front of the trailer, a piece of broken wood that had
    not been there the day before. That afternoon, Detective Desiree
    Carrington searched the trailer pursuant to a warrant. Outside
    the trailer, she saw a wooden stick, twine, a chair, an iced tea
    can, a beer can, a golf club, clear glass, duct tape, rope, a silver
    chain, a pair of green shorts with a brown belt, and three .22-
    caliber expended casings. In the screened porch, she found duct
    tape, a silver chain, a roll of plastic wrap inside an aluminum
    foil box, aluminum foil, and a pair of scissors. Inside the trailer,
    she saw twine, a black wallet or checkbook cover, a white tennis
    shoe, a roll of duct tape, boxes of ammunition, and a 12-pack of
    beer, among other items. There were boots under the bed, and
    inside them were three metal chains, a watch, and two wallets
    containing identification for José and Juan, $147 in American
    currency, and $80 in Mexican pesos. These items did not have
    dirt on them, and the clasps on the chains appeared undamaged.
    A piece of duct tape containing strands of dark hair was
    found in the field. A criminalist testified that the hair could
    have come from A.M.’s head. From the location of the tape,
    deputies noticed a set of faint tire tracks leading toward some
    berry bushes. Following them with the assistance of search
    dogs, they came across a manmade opening in the bushes, with
    some sticks and wood placed in front of it. This opening was
    approximately a quarter-mile from the trailer. There, they
    found an area of freshly moved dirt that appeared to be a grave.
    There were no apparent blood trails or smears leading up to it.
    6
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Near it, there was a blood-spattered, square-nosed shovel
    without a handle and a round-nosed shovel.
    The grave was rectangular, measuring approximately five
    and a half to six feet in length, two feet in width, and three feet
    in depth. Its walls were cut smoothly, at 90-degree angles. An
    excavation team unearthed a child’s leg at approximately 19
    inches deep. They then unearthed, first, a male child lying
    facedown; second, a female child lying faceup with a stick in her
    hand and her mouth open and covered with dirt; third, an adult
    male lying faceup with his legs and his right arm outstretched
    and his left arm crossed over his chest; and, finally, an adult
    male lying faceup with his legs outstretched and his hands
    crossed over his chest. There was a .22-caliber expended casing
    inside the grave and an apparent blood stain on the floor of the
    grave.
    d. The autopsies and Y.M.’s injuries
    Dr. Donald Henrikson performed the autopsies. J.M. had
    a depressed skull fracture and linear fractures extending into
    the base of his skull; contusions and abrasions on his face, back,
    and wrist; and hematomas in his shoulders, chest, and soft
    tissue near his skull. He had residue of adhesive tape around
    his mouth, cheek, arms, and legs. His mouth, trachea, and
    bronchial tree were full of dirt, and dirt was mixed with
    moisture near his mouth and nose. He was hit at least once on
    his back and eight times on his head. His back injury was
    consistent with a tubular instrument, such as a shovel handle,
    and his head injury was consistent with a shovel head. The
    blunt force trauma likely rendered him unconscious but was not
    sufficient to cause his death. He died of asphyxiation by
    7
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    obstruction of the airway due to aspiration of foreign material
    (soil).
    A.M. had three fractures in her skull, hematoma over both
    sides of her head, and contusions and abrasions on her face,
    head, trunk, arms, and legs. She held a twig, and her airways
    had mud in them. She had residue of adhesive tape on her chin,
    arms, and left ankle. The blunt force trauma likely rendered
    her unconscious but was not sufficient to cause her death. She
    died of asphyxiation due to obstruction of her airway by
    aspiration of foreign material (soil).
    José died of two gunshot wounds to his head, one to the
    back of his head and one in front of his left ear. Both were
    contact wounds, fired from less than an inch away. He also had
    abrasions and contusions on his head, trunk, arms, and right
    leg, and abrasions and contusions on his back, which suggested
    that he might have been dragged while supine.
    Juan died of three gunshot wounds to his head, all of
    which were fired from less than an inch away: one to his upper
    right forehead; one to the left side of his nose; and one to the
    back of his head on the right. He also had abrasions and
    contusions on his trunk and arms.
    Kim Marjama, a sexual assault nurse examiner,
    conducted a sexual assault examination of Y.M. Y.M. had
    swelling, contusions, abrasions, and lacerations on her face,
    blood in her right inner ear canal, and a hematoma in her right
    eye. There were swelling, contusions, and abrasions on her
    neck, and a red linear abrasion encircling her neck. She had
    contusions and abrasions on her arms and legs, and red linear
    abrasions encircling her wrists and ankles. In addition, she had
    marked edema bilaterally to her labia and a divot in her right
    8
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    inner labia. She had marked edema and contusions in the
    periurethral area, and erythematous edema and an abrasion to
    the posterior fourchette. She had normal findings inside her
    vagina, and no sperm was found. Marjama testified that the
    posterior fourchette injuries were consistent with blunt force
    trauma, which was consistent with penile penetration, and that
    the divot in the labia was indicative of digital penetration.
    e. Juarez’s flight and arrest
    On Monday, July 13, Juarez went into a drugstore in
    Auburn, purchased a shirt and a cowboy hat, and asked for
    quarters. He used a pay phone outside the store. He called,
    among others, his cousin Pablo Juarez and asked Pablo to pick
    him up at a bus station in Sacramento. Pablo did so. Juarez
    told Pablo that he had been in a fight. He said he had killed
    José, Juan, and the children, beaten Y.M., and shot José and
    Juan and put them in a hole. He told Pablo the children had
    wanted to see their father and uncle, but he did not say how he
    had killed the children. He left Pablo’s home that night.
    On Tuesday, July 14, Juarez arrived at Josefina Torres
    Yanez’s apartment in Wilmington, where she lived with Jorge
    Lucho and their children. Juarez told Torres that he had shot
    and killed his brothers-in-law in self-defense because they were
    going to kill him. He told her that he had killed the two children
    by hitting them with a stick or a shovel. He did not know why
    he had killed the children, but he said they had been crying and
    he had been nervous. He told her that he had hit and dragged
    Y.M. by her neck but had not raped her. Juarez told Lucho that
    he had gotten into an argument with two coworkers, and while
    defending himself, he had shot and killed them. Torres also
    9
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    testified that approximately a week earlier, Juarez had told her
    that his in-laws would kill him and he wanted to commit suicide.
    On Wednesday, July 15, law enforcement officers arrested
    Juarez at the apartment. From the apartment, they seized a
    cowboy hat and a bag containing some clothing, a pocket knife,
    and a pen. Following his arrest, Long Beach Police Detective
    Dennis Robbins and FBI Special Agent Elizabeth Stevens
    transported him to the police station. During the drive, Juarez
    asked Stevens, who spoke Spanish, why they had arrested him
    (or something to that effect), and she told him he was being
    arrested for four murders and the rape of a female. He said he
    did not rape the female. He also said he had planned to leave
    the following day for Mexico.
    At the station, he said the murders were true but he did
    not rape the woman. Detective Robbins and Agent Stevens
    interrogated Juarez for approximately an hour. Juarez said he
    got into a heated discussion with his brothers-in-law after they
    had accused Juarez of womanizing, which he denied. He was
    carrying a rifle, which Juan requested and placed on the ground.
    Juarez then shot the men with the rifle and dragged their bodies
    to a hole. He returned to the trailer and beat his brother-in-
    law’s wife. He did not know why he beat her but said he had
    experienced sleeplessness and nervousness. He then walked the
    children to the hole. He did not know what he intended to do
    with them. During the walk, the girl became tired, so he let go
    of the boy’s hand and carried her. Once there, he hit the boy
    with the wooden part of a shovel, then hit the girl too, put their
    bodies in the hole, and put dirt on them. He walked back to the
    trailer, saw police cars, and ran up a hill.
    10
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    After being transported to Placer County, Juarez was
    interrogated the next morning by Sergeant Bob McDonald and
    Detective Michael Bennett.         Interpreter Frank Valdes
    translated their questions into Spanish for Juarez. A tape of the
    interrogation was played.
    In the interrogation, Juarez initially said he shot José and
    Juan during an argument. He said that he then beat and tied
    Y.M. and touched her vagina. The children cried, and he taped
    them to quiet them; he removed the tape when he went outside
    the trailer, leaving Y.M. tied up. He then walked with the
    children because they wanted to see their father. The children
    calmed down. He walked them to the hole, hit them over the
    head with a stick, put them with José and Juan, and put some
    dirt over them.
    Later in the interrogation, he said that he had planned it
    all for about a week. Although he initially said he dug the hole
    that day, he subsequently said he dug the hole on Monday or
    Tuesday. He dug the hole deep enough to fit Y.M. Asked if he
    planned this because he had problems with the family, he
    replied affirmatively. He said he killed José and Juan near the
    hole, after telling them that he had shot a deer and needed them
    to go to it. He took their wallets and jewelry to avoid their being
    identified. He said he killed the children because he did not
    have any other way out. He also said that for five or six years
    he had suffered from sleeplessness and nervousness that
    affected his actions.
    f. Other evidence
    Criminalists testified that the casing found inside the
    grave and the three casings found around the trailer had been
    fired from Juarez’s .22-caliber rifle. Bullet fragments recovered
    11
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    from José and Juan could have been fired from the rifle, but
    there were insufficient points of comparison to conclude that
    they were. Scrapings from J.M. and A.M. revealed adhesive
    residue.     DNA analysis was conducted of several items,
    including the shovel, Juarez’s black pants, Y.M.’s blue
    underwear, and the scissors. Juan could not be eliminated as a
    contributor of the DNA on the shovel. Juarez and Y.M. could
    not be eliminated as contributors of the DNA on his black pants
    and on her blue underwear. Juarez could not be eliminated as
    a contributor of the DNA on the scissors, and a random match
    of this profile would be expected in approximately one in 21,000
    Hispanics. Juarez’s fingerprint also was found on duct tape.
    Finally, the jury visited the Parnell Ranch.
    2. Defense Case
    The defense cross-examined some witnesses about
    Juarez’s demeanor after July 12 and his complaints of
    headaches, sleeplessness, and nervousness. The defense also
    presented four witnesses. Y.M. testified that Juan sometimes
    did not accompany the family to the Parnell Ranch, so she did
    not know if Juarez thought Juan would accompany them on July
    12. Detective Diana Stewart testified that on July 13, Y.M. had
    said she was not sure whether she had seen Juarez’s penis
    because she had lapsed in and out of consciousness. A
    pathologist testified that Y.M.’s injuries could have been caused
    by hands or fingers, and it was inconclusive whether
    penetration had occurred. An interpreter testified about
    translation and transcription errors in the taped interrogation.
    12
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    B. Penalty Phase
    1. Prosecution Case
    Y.M. testified about the deceased victims. Juan, who was
    27 years old, participated in activities with Y.M.’s family. José,
    who was 37 years old, enjoyed helping people, playing soccer,
    and playing with his children. He planned to own a business
    and a home. J.M. and A.M. were affectionate and protected one
    another. J.M. enjoyed going to school and being outside, and
    A.M. enjoyed playing with toys, going to McDonald’s, and going
    to the park.
    When Y.M. learned about their deaths, it was “like a
    nightmare,” and she “felt that [her] life had no meaning.” She
    felt alone and hopeless. She had to learn how to drive and to
    find work to support herself. She wished she could turn back
    time and give her life for her children, and she felt a lot of pain
    for having been unable to do anything for them as they watched
    her being beaten. She missed everything about her family. She
    did not have plans for the future; she said that it was very
    difficult but that she will move on “with the help of God.”
    During her testimony, the prosecutor introduced a
    photograph of the family, a photograph of Juan with J.M. and
    A.M., and a home video of J.M. and A.M. on the day of their
    murders.
    2. Defense Case
    Juarez’s mother, Maria Suarez Aguilar, had 10 children
    with her husband, Tomas Juarez Gonzalez, in Santa Gertrudis,
    Mexico. One of the children, Abundio, died in an accident. The
    family was poor; they slept in the same room and did not have a
    bathroom inside the house. Sometimes there was no food for the
    children. Juarez was one of the youngest children. His mother
    13
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    did not take him to see a doctor or a dentist, even when he had
    the measles. He began work around the age of 10 and gave her
    his money. He later sent her money from the United States.
    She testified that until about 10 years ago, her husband
    drank almost every day, and he hit her and said nasty things to
    her. He yelled at the children but did not hit them. She recalled
    a time when her son Abundio took her to Mexico City to protect
    her.
    Juarez’s living siblings testified about their childhoods
    and expressed their love for him. Benjamin Juarez Suarez
    testified that their home did not have electricity or hot water
    when Juarez was born. Their father drank, hit their mother,
    and yelled at her and the children. Sometimes they had no food,
    and their father used their money to purchase alcohol. When
    their mother left for Mexico City, some of the siblings, including
    Juarez, stayed with their father. The family suffered when
    Abundio died. Isaias Juarez Suarez testified that their father
    drank and hit, kicked, and ripped clothing off their mother.
    When this happened, Juarez became frightened and sad. Their
    father also called the children vulgar names and hit Juarez
    several times. Later, one of Isaias’s children died from
    leukemia, and Juarez provided money for his treatments and
    funeral. Silviano Juarez Suarez testified that their father
    drank, but he hit the children only if they did something wrong.
    Beatriz Juarez Suarez testified that their father drank
    and yelled at their mother and the children. During one
    argument, he threw a glass, which cut her sister Celia Juarez.
    Celia testified about that argument and about their father
    drinking and hitting their mother, their mother leaving for
    Mexico City, and the lack of food at home. She testified that
    14
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    their father yelled at Juarez and hit him if he did something
    wrong. Daniel Juarez Suarez testified that their father drank
    and sometimes hit or squeezed Juarez. Miroslava Juarez
    Suarez testified that their father hit their mother, used money
    to buy alcohol instead of food, and hit the children when they
    did something that he did not like. Maria Juarez Suarez
    testified about their father drinking and hitting them, their
    mother leaving for Mexico City, and the lack of food at home.
    One time, their father threw her onto the bed and tried to rape
    her, but she freed herself.
    In addition, Benjamin’s wife testified that she once saw
    their father go after Abundio with a knife. Daniel’s wife testified
    that Juarez was one of her children’s godfathers and that he
    wrote her a letter when her father died. A neighbor also testified
    about their father’s drinking, and other witnesses testified
    about Juarez’s generosity. Juarez’s former teacher testified that
    he received good grades, was diligent, polite, and extroverted,
    and finished secondary school. He did not attend preparatory
    school because he thought it would be better to work and support
    his family.
    Juarez’s daughter, Liliana Juarez Martinez, testified that
    she loved him. Juarez’s wife, Isabel, testified that she gave birth
    to their daughter Liliana in 1990, and they married in a civil
    ceremony. She gave birth to their second daughter Jessica in
    1992. She lived with Juarez in the United States for a few years,
    but she returned to Mexico in 1995 when she experienced
    medical problems. He sent her money about every three weeks,
    and he brought his daughters toys when he visited them.
    Isabel testified that in 1998 she asked for a separation
    because she was jealous, but he did not agree. They ultimately
    15
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    resolved the issue between them. She also testified that he
    complained of headaches and sleeplessness, for which he
    obtained some medicine in 1998. Around this time, in March
    1998, Juarez told Daniel that he was having headaches and back
    pain, and Juarez looked sad and serious. In April 1998, Juarez
    appeared sad and moody to Beatriz and her husband.
    A clinical psychologist and psychosocial and cultural
    expert testified that Juarez’s father brought shame to the family
    and affected the children’s emotional and social development.
    When Juarez’s mother departed for Mexico City, it created a
    sense of abandonment, and Abundio’s death caused significant
    grief. The expert testified about the effects of poverty on their
    childhood and about the general experiences of migrant
    workers.
    James Esten, a correctional consultant, testified as an
    expert that Juarez would be able to adapt to the conditions of
    life imprisonment without parole, without posing a threat to
    others. While Juarez was housed in Placer County and Napa
    County, he received no disciplinary write-ups, and his security
    classification was reduced.
    II. JURY SELECTION ISSUES
    A. Challenges to Death Qualification
    “ ‘A prospective juror may be challenged for cause based
    upon his or her views regarding capital punishment only if those
    views would “ ‘prevent or substantially impair’ ” the
    performance of the juror’s duties as defined by the court’s
    instructions and the juror’s oath.’ ” (People v. Wall (2017)
    
    3 Cal.5th 1048
    , 1061–1062.) Juarez contends that this process
    of excluding prospective jurors whose views would prevent or
    substantially impair the performance of their duties creates an
    16
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    unconstitutional death penalty scheme and violates his rights
    under statutory, constitutional, and international law. He
    further contends that this process violates the rights of excluded
    prospective jurors. Except as discussed below, he does not argue
    that the excluded jurors failed to meet the applicable standard
    for exclusion; rather, he asks us to reconsider our decisions
    permitting such exclusion.
    Even if we assume that Juarez did not forfeit these claims
    and has standing to assert them, they lack merit. Juarez argues
    that our state statutes do not permit the death qualification
    process and asks us to overturn our contrary conclusion in
    People v. Riser (1956) 
    47 Cal.2d 566
     (Riser). In Riser, we
    interpreted Penal Code former section 1074 (now Code Civ.
    Proc., § 229), which provided in relevant part that “ ‘[a]
    challenge for implied bias may be taken for all or any of the
    following causes, and for no other . . . [subdivision] 8. If the
    offense charged be punishable with death, the entertaining of
    such conscientious opinions as would preclude his finding the
    defendant guilty; in which case he must neither be permitted
    nor compelled to serve as a juror.’ ” (Riser, at p. 573, quoting,
    Pen. Code, former § 1074, subd. (8).) We held that even though
    “a literal reading of section 1074, subdivision 8, does not compel
    the exclusion of jurors incapable of exercising the discretion
    contemplated by section 190” to decide whether death or life
    imprisonment is the appropriate punishment, “[i]t would be
    doing violence to the purpose of these sections of the Penal Code
    . . . to construe section 1074, subdivision 8, to permit these
    jurors to serve” and “would in all probability work a de facto
    abolition of capital punishment, a result which, whether or not
    desirable of itself . . . is hardly appropriate for this court to
    17
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    achieve by construction of an ambiguous statute.” (Riser, at
    pp. 575–576.)
    We have confirmed our holding in Riser, supra,
    
    47 Cal.2d 566
    . (See, e.g., People v. Mabry (1969) 
    71 Cal.2d 430
    ,
    445; People v. Gonzales (1967) 
    66 Cal.2d 482
    , 497–499; People v.
    Smith (1966) 
    63 Cal.2d 779
    , 789.) In People v. Hovey (1980)
    
    28 Cal.3d 1
    , 9, footnote 9 (Hovey), we stated, “Th[e] legislative
    ‘preference for one jury qualified to act throughout the entire
    case’ [citation] would seem to be inconsistent with a literal
    reading of section 1074, subdivision 8, and thus supports the
    judicial gloss placed on that section by Riser and its progeny.”
    Juarez provides no persuasive reason to overturn our precedent.
    Nor does he demonstrate that the process lacks statewide
    uniformity in its application.
    In addition, we have considered and rejected claims that
    the death qualification process is unconstitutional. (See, e.g.,
    People v. Mendoza (2016) 
    62 Cal.4th 856
    , 912–915 (Mendoza);
    People v. Chism (2014) 
    58 Cal.4th 1266
    , 1286; People v. Tully
    (2012) 
    54 Cal.4th 952
    , 1066 (Tully); People v. Taylor (2010)
    
    48 Cal.4th 574
    , 602–604 (Taylor).) As we summarized in
    Mendoza: “ ‘The death qualification process is not rendered
    unconstitutional by empirical studies concluding that, because
    it removes jurors who would automatically vote for death or for
    life, it results in juries biased against the defense. [Citations.]
    [¶] Lockhart [v. McCree (1986) 
    476 U.S. 162
    ] . . . , which
    approved the death qualification process, remains good law
    despite some criticism in law review articles. [Citations.] “We
    may not depart from the high court ruling as to the United
    States Constitution, and defendant presents no good reason to
    reconsider our ruling[s] as to the California Constitution.”
    [Citation.] [¶] . . . Nor does the process violate a defendant’s
    18
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    constitutional rights, including the Eighth Amendment right
    not to be subjected to cruel and unusual punishment, by
    affording the prosecutor an opportunity to increase the chances
    of getting a conviction. [Citations.] Defendant claims the voir
    dire process itself produces a biased jury. We have held
    otherwise. [Citation.] [¶] Death qualification does not violate
    the Sixth Amendment by undermining the functions of a jury as
    a cross-section of the community participating in the
    administration of justice.’ ” (Mendoza, at p. 914.) We have
    rejected the arguments that “the death-qualification process
    fails to produce the heightened reliability required for death
    judgments” and that the death qualification process violates
    equal protection “because capital defendants receive different,
    more conviction-prone juries than other defendants.” (Id. at
    p. 913.)
    We have found “flawed the premise underlying
    defendant’s assertion that death qualification, by eliminating
    the segment of the community that opposes the death penalty,
    skews the data courts typically rely on to determine ‘evolving
    standards of decency’ for Eighth Amendment purposes.
    Through the death qualification process, individuals may be
    excused not only for their unyielding opposition to capital
    punishment but also for their intractable support of it.
    [Citations.]   We reject defendant’s contention that death
    qualification is irrational because it disqualifies individuals
    based on their moral beliefs when the penalty phase
    determination is ‘ “inherently moral and normative.” ’
    [Citation.] Disqualified jurors are properly excused for cause,
    not on the basis of their personal, moral beliefs regarding the
    death penalty, but because of their inability to ‘temporarily set
    19
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    aside their own beliefs in deference to the rule of law.’ ” (Taylor,
    
    supra,
     48 Cal.4th at pp. 603–604.)
    We have rejected the argument that death qualification
    violates a defendant’s right to a jury selected from a
    representative cross-section of the community. (Taylor, 
    supra,
    48 Cal.4th at p. 603.) We have concluded that “ ‘[t]he impacts of
    the death qualification process on the race, gender, and religion
    of the jurors do not affect its constitutionality.’ ” (Mendoza,
    supra, 62 Cal.4th at p. 914; accord, Tully, supra, 54 Cal.4th at
    p. 1066.) We have rejected “[the] further assertion that death
    qualification violates [a defendant’s] right to a representative
    jury because empirical studies show that the process results in
    a disproportionate number of ethnic minorities, women, and
    religious individuals being removed from capital juries.”
    (Taylor, 
    supra,
     48 Cal.4th at p. 603.) “As the high court
    explained in rejecting a defendant’s claim of an
    unrepresentative jury, unlike the impermissible removal of
    ethnic minorities or women from jury service, ‘ “[d]eath
    qualification” . . . is carefully designed to serve the State’s
    concededly legitimate interest in obtaining a single jury that can
    properly and impartially apply the law to the facts of the case at
    both the guilt and sentencing phases of a capital trial. There is
    very little danger . . . that “death qualification” was instituted
    as a means for the State to arbitrarily skew the composition of
    capital-case juries.’ ” (Ibid., quoting Lockhart v. McCree, 
    supra,
    476 U.S. at pp. 175–176.) Although Juarez cites recent studies
    purporting to show troubling data that “blacks are significantly
    more likely than whites to be excluded from capital juries
    through death qualification,” these studies do not establish,
    contrary to our precedent, that the death qualification process
    is unconstitutional.
    20
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    We also find unpersuasive the related claim that this
    process violates the rights of excluded prospective jurors. As the
    high court has stated, “the removal for cause of ‘Witherspoon-
    excludables’ in capital cases does not prevent them from serving
    as jurors in other criminal cases, and thus leads to no
    substantial deprivation of their basic rights of citizenship. They
    are treated no differently than any juror who expresses the view
    that he would be unable to follow the law in a particular case.”
    (Lockhart v. McCree, 
    supra,
     476 U.S. at p. 176; see Witherspoon
    v. Illinois (1968) 
    391 U.S. 510
    .) Again, the death qualification
    process “is carefully designed to serve the State’s concededly
    legitimate interest in obtaining a single jury that can properly
    and impartially apply the law to the facts of the case at both the
    guilt and sentencing phases of a capital trial.” (Lockhart, at
    pp. 175–176.)
    Finally, we have concluded that the death qualification
    process does not violate international law. (See People v. Krebs
    (2019) 
    8 Cal.5th 265
    , 351.)        In sum, we reject Juarez’s
    contentions that the death qualification process violates
    statutory, constitutional, or international law.
    B. Excusal of Prospective Juror Deborah B. for
    Cause
    Juarez contends that the trial court erred in excusing
    Prospective Juror Deborah B. based on her views about the
    death penalty.
    “Under Wainwright v. Witt (1985) 
    469 U.S. 412
    , 424
    [
    83 L.Ed.2d 841
    , 
    105 S.Ct. 844
    ] (Witt), we consider whether the
    record fairly supports the trial court’s determination that [a
    prospective juror’s] views on the death penalty would have
    prevented or substantially impaired her performance as a
    21
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    juror.”    (People v. Thomas (2011) 
    52 Cal.4th 336
    , 357.)
    “ ‘ “Generally, a trial court’s rulings on motions to exclude for
    cause are afforded deference on appeal, for ‘appellate courts
    recognize that a trial judge who observes and speaks with a
    prospective juror and hears that person’s responses (noting,
    among other things, the person’s tone of voice, apparent level of
    confidence, and demeanor), gleans valuable information that
    simply does not appear on the record.’ ” ’ ” (Id. at p. 358.)
    “ ‘When the prospective juror’s answers on voir dire are
    conflicting or equivocal, the trial court’s findings as to the
    prospective juror’s state of mind are binding on appellate courts
    if supported by substantial evidence.’ ” (People v. Wall, supra,
    3 Cal.5th at p. 1062.)
    In Prospective Juror Deborah B.’s jury questionnaire, she
    wrote, “If the person is found guilty and the jurors have found
    them guilty then I believe in the death penalty.” She believed
    the state should automatically put someone to death for
    intentionally killing a human being, murdering more than one
    human being, randomly killing a human being for no apparent
    reason, or killing a child. Asked in what kind of murder case life
    imprisonment without the possibility of parole might be
    appropriate, she wrote, “I believe if you went out to murder
    someone and you killed them — death penalty — if the murder
    was an accident life without the possibility of parole.” She said
    that she did not have views or beliefs that would make it either
    impossible or extremely difficult for her to consider or vote for
    the death penalty, and she would not automatically vote for the
    death penalty or life imprisonment without the possibility of
    parole based on the information she knew about this case. She
    identified herself as belonging to group 4, which was defined as
    22
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    having some doubts or reservations about the death penalty but
    not always voting against it.
    She expressed some hesitation, however, about her ability
    to vote for the death penalty. Asked her general feelings about
    the death penalty, she wrote, “I do not feel this is my job giving
    someone the death penalty[.] I am not God.” She said she did
    not have strong opinions about the death penalty, but
    commented, “I just would not like to give someone a death
    penalty.” Asked whether she supported the death penalty, she
    checked both the yes and the no boxes, explaining, “I believe in
    the death penalty but would not want to be the juror who had to
    make the decision.” She likewise checked both the yes and the
    no boxes when asked whether she opposed the death penalty;
    whether she would refuse to find the defendant guilty or the
    special circumstances true solely to avoid having to make a
    decision on the death penalty; whether she would automatically
    vote for life imprisonment without the possibility of parole; and
    whether she would automatically vote for the death penalty.
    She created and checked a box labeled “not sure” when asked
    whether she could personally vote for the death penalty if the
    facts warranted it, and commented, “I am not sure if I could do
    this or not.”
    During questioning pursuant to Hovey, supra, 
    28 Cal.3d 1
    ,
    Deborah B. confirmed that she was not philosophically opposed
    to the death penalty, but she had strong reservations about
    personally serving as a juror in a capital case. She said that she
    would not be able to vote for a death sentence if the aggravating
    factors substantially outweighed the mitigating factors and
    even if there were four murders, including two murders of
    children. When asked whether she would be willing to serve as
    a juror in a capital case, she responded, “I would. But like I told
    23
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    him I probably couldn’t. You know, I’m just being truthful. And
    the more I thought about it the whole week that I been here and
    then came back, I just kept confirming that in my mind. I’m a
    teacher, and I deal with children every day. I just — I just
    couldn’t play that role. Even though maybe I did feel that’s what
    he deserved, that’s not my right I feel for myself. Maybe other
    people feel they could do that, and that’s fine. And maybe that’s
    what he did deserve, but I in my heart could not do that. I would
    be a hold up or — I just couldn’t do that.”
    When asked whether she would listen to and follow the
    trial court’s instructions, she responded, “Absolutely.” When
    asked whether she could, as opposed to would, vote for the death
    penalty if the aggravating circumstances outweighed the
    mitigating circumstances, she responded, “I mean is it my right
    to be able to vote no? I mean I just couldn’t do that. I couldn’t
    in my heart. That’s — I couldn’t unless that was the law.
    Because the law says if the evidence is — if the evidence was
    there, and that was something I had to do, then I guess I would
    have to do it.”
    She then confirmed that there was no conceivable set of
    facts under which her view would allow her to vote for the death
    penalty, explaining, “It’s just really hard. I know if it was my
    own children, and this happened to them, then of course I would
    say yes I could. And I would want that for my own family. But
    that’s not the situation right now. This is something completely
    different. And I don’t think I — even though I felt he was guilty,
    and he deserved a punishment, that that could be up to me to
    give to him.” She agreed that her view was essentially “there is
    no reason to put on a penalty phase because [she] wouldn’t listen
    to or weigh the aggravating and mitigating circumstances in any
    24
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    meaningful way because whatever ended up happening [she’d]
    be voting for life without parole rather than death anyway.”
    The trial court excused Prospective Juror Deborah B. over
    the defense’s objection. The court stated, “I couldn’t get one iota
    of willingness to impose the death penalty in this or any other
    case.” The court continued, “In evaluating her demeanor she
    was completely certain when she answered the question she was
    asked about whether she could impose a death sentence. I am
    entirely satisfied that this is a person who would not be able to
    follow the court’s instructions to evaluate the evidence, and only
    reach a decision as to death or life without parole after having
    done so. This is a person who would not be able to impose a
    death sentence no matter what case was before her.”
    The trial court did not err. Although Deborah B.
    supported the death penalty in theory, she gave equivocal
    responses in her questionnaire about her ability to impose it.
    She then said during Hovey questioning that she would not be
    able to vote for a death sentence if the aggravating factors
    substantially outweighed the mitigating factors and even if
    there were four murders, including two murders of children.
    She agreed that her view was essentially “there is no reason to
    put on a penalty phase because [she] wouldn’t listen to or weigh
    the aggravating and mitigating circumstances in any
    meaningful way because whatever ended up happening [she’d]
    be voting for life without parole rather than death anyway.” To
    the extent Juarez argues that the trial court erred because
    Deborah B. said she would follow the law, we disagree. She said
    that she could not vote for the death penalty “unless that was
    the law . . . and that was something [she] had to do.” But a
    “prospective juror’s statement that he thought he could vote for
    death ‘if [he] had to’ would not necessarily have established that,
    25
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    contrary to the trial court’s finding, he could perform his duties
    as a juror. Clearly, a juror is never required to vote for the death
    penalty.”    (People v. Bryant, Smith and Wheeler (2014)
    
    60 Cal.4th 335
    , 401.)      We therefore find that substantial
    evidence supports the trial court’s excusal of Deborah B.
    C. Denial of Challenges for Cause
    Juarez contends that the trial court erred in denying his
    challenges for cause of 16 prospective jurors who, he claims,
    were biased in favor of the death penalty. “[T]o preserve this
    claim for appeal we require, first, that a litigant actually
    exercise a peremptory challenge and remove the prospective
    juror in question. Next, the litigant must exhaust all of the
    peremptory challenges allocated by statute and hold none in
    reserve. Finally, counsel (or defendant, if proceeding pro se)
    must express to the trial court dissatisfaction with the jury as
    presently constituted.” (People v. Mills (2010) 
    48 Cal.4th 158
    ,
    186.)
    Juarez failed to preserve his claim for appeal. He
    exercised peremptory challenges against only six of the 16
    prospective jurors. He did not exhaust all of his peremptory
    challenges as to the main jury panel, although he did as to the
    alternate panel. Nor did he express dissatisfaction with the jury
    to the trial court. Indeed, he does not deny these facts but rather
    urges us to set aside the forfeiture rule. We have previously
    declined to do so (People v. Manibusan (2013) 
    58 Cal.4th 40
    , 61),
    and he provides no persuasive reason for us to do so here.
    III. INTERPRETER ISSUES
    Juarez contends that “shoddy and inaccurate
    interpretative and translation assistance and services” violated
    his state constitutional right “to an interpreter throughout the
    26
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    proceedings” (Cal. Const., art. I, § 14) and to his state and
    federal constitutional rights to due process, to be present during
    trial, to confront witnesses, and to a reliable process and
    sentence.
    A. Issues Regarding Y.M.’s Preliminary Hearing
    Testimony
    Juarez challenges the use of an unsworn, uncertified
    interpreter, Ximena Oliver, to interpret Y.M.’s testimony at the
    preliminary hearing.
    In general, interpreters are required to take an oath and
    to be certified. (Evid. Code, § 751, subd. (a); Gov. Code, § 68561,
    subd. (a).) A trial court, however, may use an interpreter who is
    not certified if there is “good cause” to do so. (Gov. Code,
    § 68561, subd. (a).) In that situation, the court must find,
    among other things, that good cause exists and that the
    interpreter is qualified to interpret the proceedings. (See Cal.
    Rules of Court, rule 2.893 [formerly rule 984.2].)
    It is uncontested that Oliver was neither sworn nor court-
    certified, except with respect to administrative hearings. When
    Juarez moved to dismiss the information on these grounds, the
    trial court denied the motion. The court found that Juarez had
    not waived his right to her oath or certification, but he had
    waived any issues as to the accuracy or competency of her
    interpretation and there was no prejudice.
    “Improper procedures in the use of an interpreter do not
    rise to the level of a constitutional violation unless they result
    in prejudice demonstrating defendant was denied his right to a
    fair trial.”    (People v. Superior Court (Almaraz) (2001)
    
    89 Cal.App.4th 1353
    , 1360; see 
    id.
     at pp. 1359–1360 [failure to
    follow procedural requirements or administer oath for an
    27
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    interpreter alone does not deprive a defendant of the
    constitutional right to an interpreter].) Further, “a conviction
    will not be reversed because of errors or irregularities that
    occurred at a preliminary hearing or grand jury proceeding,
    absent a showing that the asserted errors ‘deprived [the
    defendant] of a fair trial or otherwise resulted in actual
    prejudice relating to [the] conviction.’ ” (People v. Carrington
    (2009) 
    47 Cal.4th 145
    , 178; People v. Estrada (1986)
    
    176 Cal.App.3d 410
    , 414, 416 [applying standard and finding no
    prejudice as a result of a noncertified interpreter having served
    as defendant’s personal interpreter at the preliminary hearing].)
    We see no prejudice here. At the time of Oliver’s
    interpretation, Juarez had an independent interpreter. Oliver’s
    interpretation contained some errors, but defense counsel
    represented that a certified interpreter had listened to Oliver’s
    interpretation and determined it to be “guardedly acceptable.”
    And more importantly, Y.M. testified at trial, and Juarez
    acknowledges that any “[p]rejudice was restricted to the
    preliminary hearing, and could have been cured by subsequent
    trial testimony.”
    Juarez next challenges the use of his interpreter to
    translate an outburst at the preliminary hearing and his
    absence when his interpreter did so. While Y.M. testified, the
    prosecutor remarked that she was “obviously upset” and asked
    for a break. The court declared a recess until the next morning.
    The court then reconvened and stated for the record that Y.M.
    had yelled something in Spanish. The court believed her
    statements were made shortly after the recess, but there was
    some dispute about their timing relative to the recess.
    28
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    When the court reconvened, counsel and Juarez’s
    interpreter, Terri Bullington, were present, but he was not. The
    court initially asked Bullington to interpret Y.M.’s statements,
    but defense counsel asked that Oliver instead interpret them.
    After clarifying that Oliver was in the building, the court agreed.
    The court asked whether defense counsel wanted Juarez there,
    and upon learning that he was not in the building, defense
    counsel agreed to make a record and catch him up. Oliver then
    interpreted Y.M.’s statements. While doing so, Oliver said that
    “[u]nless the other interpreter knows,” she did not know how to
    interpret the word “desgraciado.” Bullington remarked, “That
    caught me, too. Like ‘a horrible person.’ ” Oliver elaborated
    about that word and ultimately summarized that Y.M. had said,
    “damn you” three times; “desgraciado” twice; “I hope you burn
    in hell”; and “I cannot take this any longer.” The court said that
    unless counsel wished to address anything, it would recess and
    repeat this interpretation the next day. The court then said,
    “Ms. Bullington?” Bullington said, “I can add two things. She
    also said, ‘I hate you’ and she said, ‘Why?’ ” The court asked
    whether Bullington could add anything else, and Bullington
    said that she agreed with Oliver’s interpretation. The next
    morning, defense counsel confirmed that Bullington had
    translated a transcript of this session to Juarez.
    Juarez moved to dismiss the entire action, arguing that
    his absence from and Bullington’s involvement in this session
    violated his rights. The trial court denied the motion. The court
    explained that the bailiff had loaded him immediately into the
    transport van for his security after Y.M. had yelled and two
    courtroom spectators had leaned forward and tried to say
    something to him. Despite his absence, the court had thought
    that Y.M.’s statements should be interpreted “while memories
    29
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    were freshest.” The court concluded that this was not a critical
    stage of the proceedings. The court further explained that it
    initially asked Bullington to interpret Y.M.’s statements
    because it believed Oliver had left. But after learning otherwise,
    the court asked for Oliver’s interpretation. Bullington then
    volunteered a couple of comments about that interpretation.
    The court concluded that this did not compromise Juarez’s
    relationship with her. The court ultimately struck Y.M.’s
    statements from the record. When Juarez subsequently moved
    to dismiss the information on these grounds, the trial court
    denied the motion, finding that he was present during all
    testimony in support of the charges, that Bullington’s
    involvement “did not deny [him] his right to a dedicated
    interpreter,” and that he suffered no prejudice.
    “ ‘A criminal defendant’s right to be personally present at
    trial is guaranteed under the federal Constitution by the
    confrontation clause of the Sixth Amendment and the due
    process clause of the Fourteenth Amendment. It is also required
    by section 15 of article I of the California Constitution and by
    sections 977 and 1043.’         [Citation.]   ‘Under the Sixth
    Amendment, a defendant has the right to be personally present
    at any proceeding in which his appearance is necessary to
    prevent “interference with [his] opportunity for effective cross-
    examination.” ’ [Citation.] ‘Due process guarantees the right to
    be present at any “stage that is critical to [the] outcome” and
    where the defendant’s “presence would contribute to the
    fairness of the procedure.” ’         [Citation.]   ‘ “The state
    constitutional right to be present at trial is generally
    coextensive with the federal due process right. [Citations.]”
    [Citation.] Neither the state nor the federal Constitution, nor
    the statutory requirements of sections 977 and 1043, require the
    30
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    defendant’s personal appearance at proceedings where his
    presence bears no reasonable, substantial relation to his
    opportunity to defend the charges against him. [Citations.]’
    [Citation.] ‘Defendant has the burden of demonstrating that his
    absence prejudiced his case or denied him a fair trial.’ ” (People
    v. Blacksher (2011) 
    52 Cal.4th 769
    , 798–799, fn. omitted
    (Blacksher).)
    Here, Juarez was present until the court recessed. He was
    absent when Oliver interpreted Y.M.’s outburst. The outburst
    occurred at the preliminary hearing, possibly after the court
    recessed; it did not respond to a question or describe the crimes
    with which he was charged, and it was ultimately struck from
    the record. We conclude that his presence “was not necessary
    for effective cross-examination or to contribute to the fairness of
    the procedure. His absence did not deprive him of the full
    opportunity to defend against the charges.” (Blacksher, 
    supra,
    52 Cal.4th at p. 799.) In any event, it was harmless beyond a
    reasonable doubt. (Mendoza, supra, 62 Cal.4th at p. 902
    [federal constitutional error “ ‘pertaining to a defendant’s
    presence is evaluated under the harmless-beyond-a-reasonable-
    doubt standard’ ”].) Bullington translated the transcript to him,
    and he “suggests nothing counsel might have done differently
    had he been able to consult with [him]” at the session. (People
    v. Butler (2009) 
    46 Cal.4th 847
    , 864.) We thus conclude that
    Juarez fails to show how his absence “affected his ability to
    defend himself or otherwise prejudiced his case.” (Blacksher, at
    p. 800.)
    We further conclude that Bullington’s involvement in the
    session did not violate Juarez’s rights. “A person unable to
    understand English who is charged with a crime has a right to
    an interpreter throughout the proceedings.” (Cal. Const., art. I,
    31
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    § 14.) “The California Constitution, as interpreted by the
    California Supreme Court, makes it clear that a defendant is
    entitled to two interpreters, one to interpret the witnesses’
    testimony and the other to be the personal interpreter for the
    defendant.” (People v. Estrada, supra, 176 Cal.App.3d at
    p. 415.) Here, Oliver interpreted Y.M.’s statements. Oliver
    prompted Bullington to assist in defining one word, and
    Bullington added to Oliver’s interpretation. This assistance did
    not deprive Juarez of his right to an interpreter. (Cf. People v.
    Aguilar (1984) 
    35 Cal.3d 785
    , 793 [separate defense interpreter
    may “ ‘serve to ensure the accuracy of . . . witness
    interpreters’ ”].) Moreover, even if we assume that a violation
    occurred, it was harmless beyond a reasonable doubt. (See
    People v. Rodriguez (1986) 
    42 Cal.3d 1005
    , 1010–1012.) There
    is nothing in the record to show that his “ability to communicate
    [with Bullington] or comprehend was impeded” (id. at p. 1014;
    see 
    id.
     at pp. 1014–1016) or that he was otherwise prejudiced or
    deprived of a fair trial (People v. Carrington, supra, 47 Cal.4th
    at p. 178).
    B. The Courtroom Audio Equipment
    Juarez contends that the courtroom audio equipment in
    Placer County and Napa County “prejudicially interfered with
    proper interpretative assistance.” He argues that counsel,
    witnesses, and interpreters expressed difficulty hearing
    throughout the proceedings. He also points out issues with
    Y.M.’s testimony.
    At the preliminary hearing, Y.M. did not use a
    microphone, but her interpreter did. At trial, Y.M. used a
    microphone and her testimony was recorded, but she spoke
    “very, very quietly.” After her trial testimony on March 14,
    32
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    2001, defense counsel told the court the following morning that
    they could not hear her “at all yesterday, basically,” that they
    “were having some difficulty with translation,” and that Juarez
    “was having difficulty following.” Defense counsel requested
    that Juarez listen to Y.M.’s testimony in Spanish rather than
    have his interpreter interpret it for him. He confirmed that he
    preferred this approach and added, “If she could raise her voice
    so I could hear what she says because yesterday I couldn’t hear
    anything.” The court granted the request and provided her an
    additional microphone.
    Trial courts should endeavor to ensure that all
    participants can adequately hear the proceedings, making
    appropriate use of technology. Our review of the record here
    reveals that the acoustics and audio equipment in the
    proceedings were poor. But the record also reflects that counsel,
    witnesses, and interpreters routinely interrupted the
    proceedings to express their difficulty hearing and to request
    clarification, which they received. Juarez does not claim on
    appeal that the trial court denied any request he made to clarify
    the proceedings or otherwise minimize the hearing difficulties.
    As to Y.M.’s March 14 testimony, defense counsel
    expressed difficulty hearing and requested clarification, which
    he received, a couple times. It was not until the next day that
    defense counsel said they could not hear Y.M. “at all yesterday,
    basically.” Had defense counsel raised the issue sooner, the
    court could have remedied the issue sooner. And once defense
    counsel raised the issue, the court accommodated the defense’s
    requests. Moreover, there is little in the record to suggest that
    Y.M.’s interpreter could not hear her or accurately interpret her
    testimony into English, or that Juarez’s interpreter could not
    hear Y.M.’s interpreter or accurately translate her
    33
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    interpretation into Spanish, except for defense counsel’s
    reference the next day to “some difficulty with translation.” We
    are unable to conclude on this record “that the hearing
    difficulties adversely affected the defense, or prejudiced
    defendant in any way.” (People v. Freeman (1994) 
    8 Cal.4th 450
    ,
    479–480.)
    C. The Accuracy of Interpreters
    Juarez argues that the interpreter Valdes made errors
    during Juarez’s interrogation on July 16, 1998 in Placer County,
    that the transcript of the same interrogation contained
    additional errors, and that the trial court erred in denying his
    motion for a mistrial on these grounds. Juarez further argues
    that Valdes should not have served as the interpreter for both
    him and the interrogators.
    “ ‘A mistrial should be granted if the court is apprised of
    prejudice that it judges incurable by admonition or instruction.
    [Citation.]    Whether a particular incident is incurably
    prejudicial is by its nature a speculative matter, and the trial
    court is vested with considerable discretion in ruling on mistrial
    motions.’ ” (People v. Hines (1997) 
    15 Cal.4th 997
    , 1038.)
    We conclude that the trial court did not abuse its
    discretion by determining that any prejudice here was curable.
    An interpreter testified that despite some errors, Valdes’s
    interpretation retained its integrity, and there was adequate
    communication during the interrogation. The court found only
    one significant error in the transcript and concluded that it was
    “imminently [sic] correctable.” The court told the jury that the
    transcript contained transcription inaccuracies and that the
    tape, not the transcript, was the evidence. As to the one
    significant error, the court told the jury, “On page 44 of the
    34
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    transcript the defendant was asked the question: [¶] ‘Why didn’t
    you kill her? You were going to come back and kill her?’ [¶] And
    the transcript indicates that his answer was, ‘No. First I was
    going to take her to see the children.’ [¶] When it comes time to
    evaluating the tape, listen carefully to that answer, for example,
    because you may find that the actual answer is, ‘No, well, first I
    was going to take the children,’ which is significantly different.”
    Later, the defense also presented testimony to the jury about
    interpretation and transcription errors in the interrogation.
    Considering these circumstances, we conclude that the alleged
    errors related to his interrogation did not violate his
    constitutional rights or deprive him of a fair trial.
    Juarez next argues that there were other interpretation
    errors “throughout this record,” citing as examples three
    instances in which interpretations were incorrect or clarified.
    To the extent he raises for the first time on appeal errors
    committed by witness interpreters, he has forfeited his claim.
    (People v. Romero (2008) 
    44 Cal.4th 386
    , 411.) In any event, he
    fails to show that any errors violated his rights or prejudiced
    him.
    Finally, he contends that the trial court erred in denying
    his request for a supplemental “check” interpreter. The court
    denied his request because he failed to show his need for such
    an interpreter, but the court did permit him to tape-record the
    testimony of Spanish-speaking witnesses. On appeal, he argues
    that he needed a “check” interpreter because “[c]ounsel were in
    no position themselves to know when translations were full and
    accurate, and the issue had been a recurring one.” He relies on
    People v. Aranda (1986) 
    186 Cal.App.3d 230
    , 237, which stated,
    “When a showing is made, at trial, that an interpreter may be
    biased or his skills deficient, one solution may be appointment
    35
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    of a ‘check interpreter.’ ” But Juarez did not make such a
    showing; thus the court did not err.
    IV. GUILT PHASE ISSUES
    A. Denial of Motion to Suppress
    Juarez contends that the trial court erred in denying his
    motion to suppress evidence seized from his trailer. Admitting
    this evidence, he contends, violated his Fourth Amendment
    rights and his state and federal constitutional rights to a fair
    trial, due process, and a reliable penalty determination.
    1. Searches of Trailer on July 12
    Shortly after arriving at the Parnell Ranch on July 12,
    Deputies Walker and Reed entered Juarez’s trailer to look for
    him and the missing family members. They were inside the
    trailer for “[p]robably less than two minutes.” They “lifted up
    things, looked underneath things, opened up cupboards,” and
    opened up “anything and everything . . . that somebody could
    hide in.” Deputy Walker saw some duct tape and “something to
    indicate that somebody had been tied up.” When he went into
    the bed area, “[i]mmediately [he] could see there was
    ammunition for various guns, rifles, all around.” Deputy Reed
    found two rifles in the bed area, one under and one above the
    bed. They seized the rifles but nothing else. Deputy Walker
    testified that they seized the rifles for safekeeping because the
    Parnell Ranch was “such a big area, 160 acres,” they were
    concerned Juarez might come back to the trailer, and they did
    not want the rifles to “be used against [them] or anyone else.”
    Upon exiting, they did not place crime scene tape or a deputy at
    the trailer door because they did not have “enough manpower at
    that point.” They also searched the yard surrounding the
    trailer.
    36
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Around 11:45 p.m. that night, Detective Summers and
    Deputy Owens entered Juarez’s trailer in an effort to locate
    identifying information about him and the missing family
    members. Detective Summers testified that he was inside for
    approximately three minutes, but Deputy Owens guessed that
    he was inside for 10 or 15 minutes. Detective Summers saw
    some duct tape, ammunition, and cord, among other things. He
    picked up a checkbook cover and found José’s driver’s license
    inside it. He seized the license and two envelopes containing
    vehicle registration and tax records.
    At the suppression hearing, Detective Summers explained
    that before he entered the trailer, he had limited information
    about the identities of the suspect and the missing family
    members. In particular, there was some confusion as to whether
    the suspect’s name was Arturo Suarez or Arturo Juarez. Other
    witnesses testified about the identifying information known
    that night. Some suggested it was limited; some suggested
    otherwise.
    The Placer County trial court denied the motion to
    suppress evidence seized during these warrantless entries. The
    court concluded that Juarez abandoned his trailer because he
    fled the crime scene, was located “several hundred miles away,”
    and did not intend to return. Accordingly, there was no
    requirement for a warrant. In addition, the court concluded that
    Deputy Reed’s entry was a “legitimate protective sweep.” The
    court found that “it was clear that there was no entry with the
    purpose of searching, but rather [there was] a protective or a
    body search . . . simply searching for people.” “It was a quick
    walk-through,” and it was justified by “unquestionably” exigent
    circumstances because “[t]here was a fresh report of a violent
    assault” and the suspect and the family members, including
    37
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    children, were missing. The court concluded that when the
    officers “noticed the rifles,” the rifles were appropriately seized
    “as a matter of public safety since the defendant . . . from the
    officer’s point of view could return to the residence and use the
    weapons offensively.”
    The court further concluded that Detective Summers’s
    entry was justified by exigent circumstances because the
    suspect and the family members remained missing. The court
    found that “[t]estimony is, frankly, confused on the point at
    which the defendant’s full identity was determined by the
    police.” But the court found that “it was clear, at least in
    Detective Summers’s mind, that he was seeking verification of
    the identity” given that “he did not conduct a general search of
    the premises but simply went to the property for the very
    superficial walk-through” and seized items that “obviously
    contained elements of identity.” As to this last part, the defense
    renewed the motion to suppress on the ground that trial
    testimony regarding what identifying information was known
    that night affected the ruling. The Napa County trial court
    concluded that there was no need for a reopened hearing
    because the testimony “does nothing to undercut the ruling itself
    that the defendant had abandoned” the trailer.
    “ ‘ “In ruling on a motion to suppress, the trial court must
    find the historical facts, select the rule of law, and apply it to the
    facts in order to determine whether the law as applied has been
    violated. We review the court’s resolution of the factual inquiry
    under the deferential substantial-evidence standard. The ruling
    on whether the applicable law applies to the facts is a mixed
    question of law and fact that is subject to independent
    review.” ’ ” (People v. Bryant, Smith and Wheeler, supra,
    60 Cal.4th at p. 364.) “ ‘[W]e consider the correctness of the trial
    38
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    court’s ruling itself, not the correctness of the trial court’s
    reasons for reaching its decision.’ ” (Id. at pp. 364–365.)
    A warrantless entry into a home is a violation of the
    Fourth Amendment unless an exception to the warrant
    requirement exists. (See Florida v. Jardines (2013) 
    569 U.S. 1
    ,
    6 [“[W]hen it comes to the Fourth Amendment, the home is first
    among equals.”].) “ ‘A long-recognized exception to the warrant
    requirement exists when “exigent circumstances” make
    necessary the conduct of a warrantless search. . . . “ ‘[E]xigent
    circumstances’ means an emergency situation requiring swift
    action to prevent imminent danger to life or serious damage to
    property, or to forestall the imminent escape of a suspect or
    destruction of evidence.” ’ ”      (People v. Panah (2005)
    
    35 Cal.4th 395
    , 465.)
    We conclude that the trial court did not err in denying the
    motion to suppress the rifles. There were exigent circumstances
    justifying Deputy Reed’s entry. Juarez had recently attacked
    Y.M. in his trailer. When law enforcement officers arrived at
    the Parnell Ranch, Y.M. appeared “[v]ery upset,” bloody, and
    “extremely swollen.” Juarez remained at large, and the family
    members, including a three-year-old child and a five-year-old
    child, were missing. Law enforcement officers thought that
    Juarez might return to the trailer, and they did not know
    whether the missing family members also might be in the
    trailer. (See People v. Panah, 
    supra,
     35 Cal.4th at p. 466
    [exigent circumstances justified entry into an apartment to look
    for a missing child].) Once inside the trailer, Deputies Reed and
    Walker conducted a “quick walk-through,” and Deputy Reed
    properly seized the rifles to prevent Juarez from using them
    “against [law enforcement] or anyone else.” (See Warden v.
    Hayden (1967) 
    387 U.S. 294
    , 298 [exigencies justified police
    39
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    entering home, searching for the suspect and any weapons that
    he had used or might use against them, and seizing weapons
    found in a toilet flush tank and a clip of ammunition found
    under a mattress]; People v. Ngaue (1992) 
    8 Cal.App.4th 896
    ,
    904 [seizure of gun “was justified for officer safety” while suspect
    remained at large].)
    Whether exigent circumstances justified Detective
    Summers’s entry approximately two hours later to search for
    identifying information presents a closer issue. But any error in
    the trial court’s denial of the motion to suppress evidence seized
    during that entry was harmless beyond a reasonable doubt. The
    only evidence seized during that entry concerned the identities
    of Juarez and José. There was no dispute as to their identities
    and thus no prejudice as to this evidence. In light of our
    conclusions, we need not decide whether Juarez abandoned his
    trailer before the warrantless entries.
    2. Search of Trailer on July 13
    Detective Carrington sought a search warrant on July 13.
    In her eight-page affidavit, she said she had spoken to Detective
    Summers and Detective Stewart. She learned that Juarez lived
    in a trailer and that he had attacked Y.M., dragged her inside,
    restrained her with duct tape and twine or rope, and raped her.
    Y.M.’s injuries “were consistent with choking, beating, and
    sexual assault.” Y.M.’s husband, brother-in-law, and children
    were missing after having last been with Juarez. When deputies
    responded to her 911 call, they searched Juarez’s trailer and
    seized two rifles. Detective Summers also searched it; he found
    José’s identification in a checkbook and saw duct tape, twine or
    rope, scissors, aluminum foil, ammunition, and a tennis shoe in
    40
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    the trailer. Judge Kearney issued the warrant. Detective
    Carrington searched the trailer, its screened porch, and yard.
    The trial court denied the motion to suppress evidence
    seized pursuant to this warrant. The court again concluded that
    the trailer had been abandoned. In addition, the court
    concluded that there was probable cause to search it. The court
    found that the affidavit contained “obviously reliable police
    information,” which came largely from Detective Carrington
    speaking with Detective Summers. The court further concluded,
    “even if you were to excise all of the information obtained by
    Detective Summers, there’s enough other information in the
    warrant that would allow it to stand on its own merits.”
    Moreover, even if there was “some technical defect of the
    warrant,” Detective Carrington acted in good faith. Finally, the
    court concluded that the warrant encompassed the yard
    surrounding the trailer because it was “clearly part of the
    curtilage of the property,” but “[e]ven if there was some question
    regarding the search of the yard, virtually all of the evidence
    was in plain view and certainly there was no reasonable
    expectation of privacy being out in the yard and subject to view
    by anyone.”
    On appeal, Juarez contends that the search of his trailer
    was unlawful because he did not abandon the trailer and the
    affidavit relied on hearsay and information obtained during
    earlier entries. He also contends that, even if valid, the warrant
    did not authorize a search of the yard or specify with
    particularity the items to be seized from the yard.
    We conclude that the affidavit established probable cause.
    The description of Y.M.’s attack in the trailer, together with her
    injuries, made “it substantially probable that there was specific
    41
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    property lawfully subject to seizure presently located in” the
    trailer. (People v. Scott (2011) 
    52 Cal.4th 452
    , 483.) The fact
    that Detective Carrington learned this information after
    speaking to Detective Summers and Detective Stewart does not
    eviscerate the probable cause. (Cf. United States v. Ventresca
    (1965) 
    380 U.S. 102
    , 108 [“Thus hearsay may be the basis for
    issuance of the warrant ‘so long as there [is] a substantial basis
    for crediting the hearsay.’ ”]; People v. Gonzales (1990)
    
    51 Cal.3d 1179
    , 1206, fn. 3 [“a fellow officer’s observations,
    reported by the affiant as hearsay, are competent and
    presumptively reliable”].) Nor was it improper to include in the
    affidavit information about Deputy Reed’s warrantless entry
    into the trailer. (Cf. People v. Redd (2010) 
    48 Cal.4th 691
    , 722
    [affidavit can include information obtained during prior, lawful
    warrantless searches].) And even if the information about
    Detective Summers’s warrantless entry was excised from the
    affidavit, it would still establish probable cause given the
    description of Y.M.’s attack in the trailer, together with her
    injuries. (See People v. Williams (1988) 
    45 Cal.3d 1268
    , 1303
    [“It is the general rule that if probable cause clearly remains
    after tainted information is excised from the affidavit, a warrant
    is still valid.”].)
    We further conclude that evidence was properly seized
    from the yard, an area surrounding the trailer and enclosed by
    a wire fence. The warrant authorized a search of “the premises
    located at and described as: [¶] A silver single wide Spartan
    trailer license AB8476 wit [sic] a wooden screened porch on the
    Parnell Ranch” at an address on Mount Vernon Road in Auburn,
    County of Placer, California. Because the warrant authorized a
    search of this residence, it “also authorize[d] without so stating
    the search of the residence’s curtilage.” (U.S. v. Gorman (9th
    42
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Cir. 1996) 
    104 F.3d 272
    , 273; see also People v. Smith (1994)
    
    21 Cal.App.4th 942
    , 950 [“ ‘[A] warrant to search “premises”
    located at a particular address is sufficient to support the search
    of outbuildings and appurtenances in addition to the main
    building when the various places searched are part of a single
    integral unit.’ ”]; LaFave, Search and Seizure (5th ed. 2018)
    § 4.10(a), pp. 932–934.) In any event, several of the items in the
    yard were in plain view as Detective Carrington approached the
    trailer to execute the warrant and accordingly could be seized.
    (See People v. Carrington, supra, 47 Cal.4th at p. 166.)
    We thus conclude that the trial court did not err in denying
    the motion to suppress evidence seized pursuant to the warrant.
    In light of our conclusion, we again need not decide whether
    Juarez abandoned his trailer before this evidence was seized.
    B. Admission of Confessions
    Juarez contends that his confession on July 15 and all
    subsequent statements should have been suppressed because he
    was not advised of his rights under Miranda v. Arizona (1966)
    
    384 U.S. 436
     (Miranda) and the Vienna Convention on Consular
    Relations, April 24, 1963, 21 U.S.T. 77, T.I.A.S. No. 6820
    (Vienna Convention) and because his statements were
    involuntary.
    1. Background
    Juarez was arrested on July 15, 1998, around 8:40 p.m.
    He was “[v]ery calm, very quiet, [and] very cooperative.” Around
    9:15 p.m., Detective Robbins and FBI Special Agent Stevens,
    who spoke Spanish, drove him to the Long Beach police station.
    During the drive, Juarez asked Agent Stevens what he was
    being arrested for or something to that effect, and she told him
    that he was being arrested for the murder of four people and the
    43
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    rape of a female. He said he did not rape the woman. She said
    those were serious charges; Juarez did not respond. He then
    asked how they found him or something to that effect, and she
    said that “he placed a telephone call.” At some point, he
    commented that she spoke Spanish and that he was going to
    Mexico. She asked where he was from in Mexico; when he told
    her, she said her family was from Mexico. They arrived in Long
    Beach around 9:20 or 9:30 p.m.
    Around 10:10 p.m., in an interview room at the Long
    Beach police station, Juarez asked what were the charges
    against him, and Agent Stevens told him that he was being
    charged with four counts of murder and one count of rape. He
    said he did not rape the female. She asked whether he was
    willing to talk to them about the events, and he said the
    homicides or the murders were true. He said that he had seen
    the news and that the homicides were true but he did not rape
    the woman. She asked whether he was willing to talk to them
    about the events, and he said he was.
    She said they needed to advise him of his rights and asked
    if he read in Spanish; he said he did. She gave him an
    advisement form, and he read it. She then read it to him and,
    after each line, asked whether he understood or had questions;
    he said he understood and did not have questions. She asked if
    he was willing to give up his rights and speak to them, and he
    signed the form without hesitation.
    Translated into English, the form, titled “Consideration of
    Civil Rights,” stated: “I, Arturo Juarez Suarez, have been
    informed about my civil rights as follows.” “I have the right to
    remain silent.” “Anything [I] say will be used and can be used
    against [me] in a court of law.” “I have a right to speak to an
    44
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    attorney and have him present with me while being
    interrogated.” “If I can’t pay to contract an attorney, one will be
    assigned to represent me before the interrogation, if I desire
    one.” “I understand every one of these rights that have been
    explained before, and I wish to discuss the case with the officer.”
    “Any declarations that I make at this moment are free and
    voluntary without any promises of indulgence, severity or
    compensation.”
    After Juarez signed the form, Detective Robbins and
    Agent Stevens questioned him. Detective Robbins asked most
    of the questions, while Agent Stevens acted as an interpreter.
    Juarez said that during an argument, he shot and killed his two
    brothers-in-law and put them in a hole; he tied up and beat the
    woman; and he beat the two children, put them in the hole, and
    threw dirt on them. He was “[v]ery calm, quiet, cooperative,
    [and] speaking very clearly.” He did not indicate that he wanted
    a lawyer, did not want to talk, or did not understand the
    questions.
    The interrogation ended around 11:20 p.m. Afterward,
    Agent Stevens asked whether he was cold because she was
    “freezing”; when he indicated he was, she gave him a shirt. She
    did not recall providing him with anything to drink or eat, but
    believed they might have offered him something to drink, which
    he declined. He did not indicate that he was hungry or express
    any other discomfort.
    Around 1:00 a.m., Detective Bennett and Sergeant
    McDonald transported Juarez to Placer County by plane. He
    was “[v]ery calm, extremely cooperative [and] [m]aybe a little
    sleepy.” He slept for “a good part” of the flight but did not eat.
    Upon arrival, he was booked. Sergeant McDonald did not know
    45
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    whether he ate during booking but testified that there would
    have been food available. Sergeant McDonald also recalled
    telling him in English that they would talk later that day, to
    which he said okay or something to that effect.
    Around 11:00 a.m. on July 16, Detective Bennett and
    Sergeant McDonald interrogated Juarez with the assistance of
    an interpreter. The interrogation was videotaped and lasted
    approximately two hours. During the interrogation, he was
    calm, and he was offered a soda and pizza.
    At the beginning of the interrogation, Sergeant McDonald
    showed Juarez the form he had signed the day before and asked
    whether he recalled and understood it and whether they could
    talk. Juarez nodded his head as Sergeant McDonald asked
    these questions. He subsequently admitted that he shot José
    and Juan during an argument; that he beat and tied Y.M. and
    touched her vagina; and that he hit the children and put them
    in the hole.
    Near the end of this interrogation, Sergeant McDonald
    asked Juarez to confirm that he remembered the form he had
    previously signed regarding his rights, which he did. Sergeant
    McDonald asked him to describe his rights, and Juarez replied,
    “That I don’t understand anything.” Sergeant McDonald
    responded that Juarez had read, signed, and said he understood
    the form. Juarez replied, “I cannot understand what rights I can
    have.” Sergeant McDonald then asked whether Juarez knew,
    when they began their conversation, that he had the right to
    remain silent; Juarez replied, “Yes.” Sergeant McDonald asked
    whether Juarez understood, when they began their
    conversation, that he had the right to talk to an attorney; Juarez
    replied, “Yes.” Sergeant McDonald asked whether Juarez
    46
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    understood that he had the right to talk to an attorney before he
    talked to them; Juarez replied, “Yes.” Sergeant McDonald asked
    whether Juarez decided to talk to them; Juarez replied, “Yes.”
    Sergeant McDonald asked, “Because you wanted to and you
    didn’t want to talk to an attorney?” and Juarez replied, “What
    am I going to gain by talking to a lawyer?” Sergeant McDonald
    said, “Okay. Again, there’s nothing else you want to ask?”
    Juarez did not reply. After Detective Bennett asked about how
    the family can heal from this, Sergeant McDonald asked why
    Juarez decided to talk “in Long Beach” and “today.” Juarez said
    that he would have felt “very bad” if he did not talk. Juarez then
    asked when he would go to court. The interpreter responded to
    him. After receiving permission to do so, the interpreter also
    briefly explained to him what to expect for the first court
    appearance. The interpreter then said something about his not
    understanding the justice system, to which Detective Bennett
    said, “We still don’t.”
    The next morning, Sergeant McDonald and other law
    enforcement officials took Juarez on a walk-through at the
    Parnell Ranch, which lasted for about 15 or 20 minutes. The
    walk-through was taped, although only some sound was
    discernible. Juarez was shackled, but he appeared cooperative
    and relaxed. A sheriff’s department employee, Virginia Ferral,
    spoke Spanish and acted as an interpreter, but she was not a
    certified interpreter and did not translate her conversations
    verbatim.
    Ferral testified that she asked Juarez, “Do you remember
    the rights that were discussed and the right to an attorney?” He
    said, “Yes.” He then asked, “Can I have an attorney here?” She
    testified that Sergeant McDonald told her to say words to the
    effect of “it’s up to you,” and she told Juarez “if you want.” Ferral
    47
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    testified that Juarez then expressed concern about his safety in
    jail because some inmates wanted to kill him. The court found
    that “[i]t is unclear from the record which phrase was said or
    translated to [him], but it’s clear that [he] asked for nothing
    further regarding an attorney but turned to security concerns.”
    Ferral testified that in response to his question about
    security, she told him she understood but wanted to know
    whether he would do this walk-through. She also told him that
    they and the jail staff were obligated to protect him, that they
    could move him to another place, and that they would talk to the
    person in charge of the jail. The group then proceeded with the
    walk-through.
    That afternoon, Juarez was arraigned, and the prosecutor
    advised him of his rights under the Vienna Convention. Juarez
    said, “What for?” After conferring with him, defense counsel
    said, “I believe at this time we would like to wait. [¶] We would
    not request any such notification right now.”
    2. Asserted Violation of Miranda and Voluntariness
    “ ‘ “As a prophylactic safeguard to protect a suspect’s Fifth
    Amendment privilege against self-incrimination, the United
    States Supreme Court, in Miranda, required law enforcement
    agencies to advise a suspect, before any custodial law
    enforcement questioning, that ‘he has the right to remain silent,
    that anything he says can be used against him in a court of law,
    that he has the right to the presence of an attorney, and that if
    he cannot afford an attorney one will be appointed for him prior
    to any questioning if he so desires.” ’ ” (People v. McCurdy
    (2014) 
    59 Cal.4th 1063
    , 1085–1086.) “ ‘ “Critically, however, a
    suspect can waive these rights.” [Citation.]’ [Citation.] ‘The
    waiver must be “voluntary in the sense that it was the product
    48
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    of a free and deliberate choice rather than intimidation,
    coercion, or deception” [citation], and knowing in the sense that
    it was “made with a full awareness of both the nature of the
    right being abandoned and the consequences of the decision to
    abandon it.” ’ ” (Id. at p. 1086.)
    “ ‘The Fourteenth Amendment of the federal Constitution
    and article I, section 7 of the California Constitution make
    “inadmissible any involuntary statement obtained by a law
    enforcement officer from a criminal suspect by coercion.” ’
    [Citation.] The prosecution must prove by a preponderance of
    the evidence that a defendant freely and voluntarily gave police
    statements before the statements can be admitted. [Citation.]
    ‘ “Voluntariness does not turn on any one fact, no matter how
    apparently significant, but rather on the ‘totality of [the]
    circumstances.’ ” ’ [Citation.] The test considers several factors,
    including any element of police coercion, the length of the
    interrogation and its location and continuity, and the
    defendant’s maturity, education, and physical and mental
    health. [Citation.] The determinative question ‘ “is whether
    defendant’s choice to confess was not ‘essentially free’ because
    his will was overborne.” ’ ”         (People v. Peoples (2016)
    
    62 Cal.4th 718
    , 740.)
    “On appeal, we review independently the trial court’s legal
    determinations of whether a defendant’s statements were
    voluntary [citation], whether his Miranda waivers were
    knowingly, intelligently, and voluntarily made [citation], and
    whether his later actions constituted an invocation of his
    [rights] [citation]. We evaluate the trial court’s factual findings
    regarding the circumstances surrounding the defendant’s
    statements and waivers, and ‘ “accept the trial court’s resolution
    of disputed facts and inferences, and its evaluations of
    49
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    credibility, if supported by substantial evidence.” ’ ” (People v.
    Rundle (2008) 
    43 Cal.4th 76
    , 115.) When “an interview is
    recorded, the facts surrounding the admission or confession are
    undisputed and we may apply independent review.” (People v.
    Leon (2020) 
    8 Cal.5th 831
    , 843.)
    a. Confession in Long Beach on July 15
    Juarez claims that his confession at the Long Beach police
    station should have been suppressed. The trial court concluded
    that he was advised of his rights, “appeared to understand his
    rights,” and confessed “freely and voluntarily” after a “full and
    knowing waiver of his rights.” The court found that “some of the
    words [in the advisement form] could have been better,” but the
    discrepancies were “[a]t best” characterized as “insignificant”
    and “the substance of the Miranda rights were conveyed to [him]
    orally and in writing.” The court also found, as to all of the
    interviews, that he was “calm and cooperative” and “readily
    appeared willing to talk to the police and to fully explain the
    circumstances of the crime”; there was no evidence “of
    discomfort or stress” or that “he was forced to sign anything or
    to waive his rights”; and all of the defense’s arguments about his
    being “cold, tired or hungry are purely speculative. No evidence
    suggests that [he] actually was influenced by these factors.”
    We conclude that Juarez was adequately advised of his
    rights. The advisement form in question states that he has the
    right to remain silent, anything he says can and will be used
    against him in a court of law, he has the right to speak with an
    attorney and the right to have the attorney present while being
    interrogated, and if he cannot afford an attorney, one will be
    assigned for him before the interrogation if he so desires. Juarez
    50
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    read the form, Agent Stevens read it to him, and Juarez said he
    understood and did not have any questions.
    Juarez argues that the form was inadequate and
    misleading. An interpreter, Santiago Flores, testified that the
    word “civil” in the form’s title did not encompass criminal; the
    word “silencio” in the first sentence could mean “to be still [or]
    quiet”; the word “consultar,” which means “to seek advice,”
    should have been used to explain the right to an attorney, rather
    than “hablar,” which means “to talk, to carry on conversation”;
    and the word “discutir” in the fifth sentence could mean “to
    discuss” or “to argue or debate.”          The last sentence —
    “[c]ualquiera de las declaraciones que yo haga en este momento
    son libres y voluntarias, con ninguna promesa de indulgencia
    (severidad) o recompensa” — also could be interpreted in
    multiple ways. When asked to translate this sentence, Flores
    translated it as “[a]ny declarations that I make at this moment
    are free and voluntary without any promises of indulgence,
    severity or compensation.” When defense counsel subsequently
    asked whether this sentence has more than one translation,
    Flores testified, “No, I don’t believe so.” Following up, defense
    counsel asked whether this sentence could also mean “I can
    speak freely without any consequences as a result of my
    providing information.” Flores responded that “[i]t could” and
    elaborated, “If I — ‘whatever declaration I make would be made
    without any punishment.’ It could mean that. ‘I’m free to talk,
    but I won’t be punished for it.’ ” When the prosecutor
    subsequently asked Flores to translate this sentence again,
    Flores translated it as “[a]ny declarations that you are making
    at this moment are free and voluntary with no promise of
    indulgence, leniency, severity or compensation.” Finally, the
    signature line stated only “signature.”
    51
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    The high court has “never insisted that Miranda warnings
    be given in the exact form described in that decision.”
    (Duckworth v. Eagan (1989) 
    492 U.S. 195
    , 202.) Rather, “[t]he
    inquiry is simply whether the warnings reasonably ‘conve[y] to
    [a suspect] his rights as required by Miranda.’ ” (Id. at p. 203.)
    In Duckworth, the high court concluded that the warnings at
    issue “touched all of the bases required by Miranda. The police
    told respondent that he had the right to remain silent, that
    anything he said could be used against him in court, that he had
    the right to speak to an attorney before and during questioning,
    that he had ‘this right to the advice and presence of a lawyer
    even if [he could] not afford to hire one,’ and that he had the
    ‘right to stop answering at any time until [he] talked to a
    lawyer.’ ” (Ibid.)
    The advisement form in this case likewise touches all of
    the bases required by Miranda. It states that Juarez has the
    right to remain silent, anything he says can and will be used
    against him in a court of law, he has the right to speak with an
    attorney and the right to have the attorney present while being
    interrogated, and if he cannot afford an attorney, one will be
    assigned for him before the interrogation if he so desires. The
    trial court found that “some of the words [in the advisement
    form] could have been better,” but the discrepancies were “[a]t
    best” characterized as “insignificant” and “the substance of the
    Miranda rights were conveyed to [him] orally and in writing.”
    Although we agree that some of the words in the advisement
    form could have been more precise, “we are not persuaded . . .
    that the language was so ambiguous or confusing” that it did not
    reasonably convey his rights.         (People v. Wash (1993)
    
    6 Cal.4th 215
    , 236; cf. U.S. v. Botello-Rosales (9th Cir. 2013)
    
    728 F.3d 865
    , 867 [Miranda warnings failed to reasonably
    52
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    convey the defendant’s right to appointed counsel because the
    warnings suggested that the right to appointed counsel would
    be “contingent on the approval of a request or on the lawyer’s
    availability” and did not make clear that appointed counsel
    would be “without cost”].)
    We further conclude that, after being advised of his rights,
    Juarez validly waived them and voluntarily confessed. “To
    establish a valid Miranda waiver, the prosecution bears the
    burden of establishing by a preponderance of the evidence that
    the waiver was knowing, intelligent, and voluntary under the
    totality of the circumstances of the interrogation.” (People v.
    Linton (2013) 
    56 Cal.4th 1146
    , 1171.) In assessing whether the
    waiver was knowing and intelligent, relevant circumstances
    include “ ‘(i) the defendant’s mental capacity; (ii) whether the
    defendant signed a written waiver; (iii) whether the defendant
    was advised in his native tongue or had a translator;
    (iv) whether the defendant appeared to understand his rights;
    (v) whether the defendant’s rights were individually and
    repeatedly explained to him; and (vi) whether the defendant had
    prior experience with the criminal justice system.” (U.S. v. Price
    (9th Cir. 2019) 
    921 F.3d 777
    , 792.)
    Juarez read the advisement form written in Spanish and
    Agent Stevens read it to him, asking him after each line whether
    he understood or had any questions. Although Juarez points out
    on appeal that he had spent his life “working in fields or
    pastures,” there is no indication that he was incapable of
    understanding his rights. Having reviewed the advisement
    form, he said he understood and did not have any questions. He
    signed the form without hesitation and then actively engaged in
    the interrogation, providing an extensive account of the events.
    Agent Stevens acted as an interpreter during the interrogation.
    53
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    She previously had translated between Spanish and English in
    her role as a law enforcement agent. She had learned Spanish
    from her mother, who was Mexican. Although she did not know
    whether there was a different dialect used in the region of
    Mexico where Juarez had lived, she testified that he spoke “very
    clearly,” she “[n]ever” had any trouble understanding his
    responses, and at no point did he indicate that he did not
    understand the questions. Nor did he indicate that he did not
    want to talk. Rather, the trial court found that he “appeared to
    understand his rights” and “readily appeared willing to talk to
    the police and to fully explain the circumstances of the crime.”
    Nor do the circumstances he emphasizes amount to
    coercion. There was no suggestion of “ ‘physical intimidation,’ ”
    “ ‘coercive tactics,’ ” promises, or threats. (People v. Spencer
    (2018) 
    5 Cal.5th 642
    , 672; see 
    id.
     at pp. 672–674.) When he said
    he was cold, he was given a shirt. He did not indicate that he
    was hungry or otherwise uncomfortable. Nor did he indicate
    that his nervousness or sleeplessness affected his ability to
    understand his rights or the questions. Instead, the trial court
    found that he was “calm and cooperative,” and there was no
    evidence “of discomfort or stress” or that “he was forced to sign
    anything or to waive his rights.” Finally, the fact that he lacked
    experience with the criminal justice system did not invalidate
    his waiver or render his subsequent statements involuntary in
    the circumstances here. (See U.S. v. Bautista-Avila (9th Cir.
    1993) 
    6 F.3d 1360
    , 1364–1366 [finding valid waiver despite the
    defendant’s lack of experience with the justice system].)
    b. Confession in Placer County on July 16
    Juarez next claims that his confession in Placer County
    should have been suppressed.         “Where a subsequent
    54
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    interrogation is ‘ “reasonably contemporaneous” ’ with the prior
    waiver, and the prior waiver was ‘knowing and intelligent,’
    police need not undertake a Miranda readvisement. [Citation.]
    In determining whether a subsequent interrogation is
    reasonably contemporaneous, we consider the totality of the
    circumstances. Relevant considerations include: ‘1) the amount
    of time that has passed since the initial waiver; 2) any change
    in the identity of the interrogator or location of the
    interrogation; 3) an official reminder of the prior advisement;
    4) the suspect’s sophistication or past experience with law
    enforcement; and 5) further indicia that the defendant
    subjectively understands and waives his rights.’ ” (People v.
    Spencer, supra, 5 Cal.5th at p. 668.)
    The trial court concluded that the admonition provided
    approximately 14 hours earlier in the Long Beach interrogation
    was “reasonably contemporaneous with [the Placer County]
    interview.” The court found that at the beginning of the Placer
    County interrogation, Juarez “indicated that he recalled the
    rights given earlier; that he understood them, and that he
    agreed to talk.” At the end of the interrogation, Sergeant
    McDonald again discussed with Juarez the advisement form
    that Juarez had signed in Long Beach. The court found that
    when Sergeant McDonald asked Juarez whether he understood
    his rights, Juarez “was unable to articulate his rights generally,
    but as to each individual right, [he] replied that he understood
    that he had the right to remain silent and the right to an
    attorney.” When Sergeant McDonald asked Juarez whether he
    decided to talk to the officers because he wanted to do so and did
    not want to talk to an attorney, Juarez responded, “What am I
    going to gain by talking to a lawyer?” As to this response, the
    court found that it “indicates at least an understanding that the
    55
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    right to an attorney exists, but [Juarez] made a conscious
    decision, perhaps unwise, not to exercise it.”
    Our review of the record confirms that approximately 13
    or 14 hours elapsed between Juarez’s waiver in Long Beach and
    his interrogation in Placer County, and he remained in custody
    during that time. At the beginning of the Placer County
    interrogation, Sergeant McDonald showed Juarez the
    advisement form he signed in Long Beach, and Juarez indicated
    that he recalled and understood it. The Placer County
    interrogation was conducted in a different location by different
    law enforcement officials, and Juarez lacked experience with the
    justice system.       But considering the totality of the
    circumstances, we conclude that the Placer County
    interrogation was reasonably contemporaneous with the earlier
    advisement and waiver in Long Beach, and no Miranda
    readvisement was necessary at the outset of the Placer County
    interrogation. (Cf. People v. Pearson (2012) 
    53 Cal.4th 306
    , 317
    [interview was reasonably contemporaneous with advisement
    and waivers that occurred 27 hours earlier].)
    Juarez nevertheless contends that his statements made
    during the initial Long Beach interrogation and the subsequent
    Placer County interrogation should have been suppressed
    because he did not understand his rights. In support of his
    argument, he relies on his statements at the end of the Placer
    County interrogation indicating that he did not understand his
    rights. Those statements were made approximately 14 hours
    after the initial Long Beach interrogation, during which he told
    Agent Stevens that he understood his rights, he signed the
    advisement form, and he confessed to the murders. Juarez
    argues: “What are we to believe: a self-serving statement about
    the past [interrogation in Long Beach by Agent Stevens] that
    56
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    was not recorded, or a videotaped statement of [Juarez during
    the interrogation in Placer County]?”
    But the trial court found, after evaluating Agent Stevens’s
    credibility, that in the Long Beach interrogation, “[Juarez] told
    Agent Stevens that he did understand his rights,” “he signed the
    form,” he “had no questions,” and he “appeared to understand
    his rights” when he waived them in Long Beach. We accept the
    trial court’s evaluations of credibility where, as here, substantial
    evidence supports them. In light of these credibility findings
    and the totality of the circumstances surrounding the
    interrogation in Long Beach, we have concluded that Juarez
    validly waived his rights before that interrogation. (See
    pt. IV.B.2.a., ante.)
    As to the subsequent Placer County interrogation, Juarez
    indicated at the outset of that interrogation that he recalled and
    understood the advisement form he had signed in Long Beach.
    He then proceeded to confess again to the murders. It is true
    that at the end of the approximately two-hour interrogation,
    Sergeant McDonald asked Juarez to describe his rights, and
    Juarez said, “That I don’t understand anything” and “I cannot
    understand what rights I can have.” But Sergeant McDonald
    then followed up by asking Juarez to confirm that at the time he
    began the interrogation in Placer County, he understood he had
    the right to remain silent and the right to talk to an attorney
    stated on the form he had signed in Long Beach. For each right,
    Juarez did so confirm. Then, when Sergeant McDonald asked
    whether Juarez decided to talk to the officers because he wanted
    to do so and did not want to talk to an attorney, Juarez said,
    “What am I going to gain by talking to a lawyer?” Although this
    remark suggests that Juarez did not appreciate the value of
    speaking to an attorney, we conclude that this remark,
    57
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    considered in its context, is insufficient to call into question the
    validity of his earlier waiver. The videotape of the interrogation
    shows that the brief remark was not a genuine question
    intended to elicit an explanation of the possible benefit of
    speaking to an attorney. The remark occurred in the course of
    Sergeant McDonald wrapping up the interrogation, and it is
    evident from Juarez’s tone, body language, and lack of further
    questions that he was not seeking or expecting to receive
    information about what he could gain from talking to an
    attorney. Instead, the remark simply appeared to convey
    Juarez’s perception that it would be futile to consult a lawyer in
    light of his predicament. Even if this perception was “unwise,”
    as the trial court suggested, it fails to show that Juarez did not
    understand he had the right to speak with a lawyer.
    Thus, considering Juarez’s statements at the end of the
    Placer County interrogation in context, we do not find those
    statements to alter our conclusions that he validly waived his
    rights before the Long Beach interrogation and that no
    readvisement was required before the Placer County
    interrogation.
    We additionally conclude that his confession was
    voluntary. In arguing to the contrary, Juarez emphasizes many
    of the same circumstances discussed above and adds that he was
    tired and weak after flying to Placer County. He asserts that he
    got little sleep and no food from his arrest around 8:40 p.m. on
    July 15 until his interrogation during the morning of July 16 in
    Placer County. But the record contains no indication that
    Juarez complained of hunger or weakness during the Placer
    County interrogation, or that any coercion rendered Juarez’s
    statements involuntary.
    58
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    c. Walk-through of the Parnell Ranch on July 17
    When Juarez moved to suppress his statements made
    during the walk-through as involuntary and obtained in
    violation of his rights, the trial court denied his motion. But the
    court subsequently excluded the videotape of the walk-through
    as unduly prejudicial. Because there was no possible prejudice
    at trial stemming from his walk-through at the ranch, we need
    not address this issue.
    3. Asserted Violation of the Vienna Convention
    Juarez further argues that the police did not advise him
    in a timely manner of his right to have his consulate notified of
    his arrest, in violation of Article 36 of the Vienna Convention
    and Penal Code section 834c. He argues that the trial court
    should have suppressed his statements, found the violation
    intentional, and considered it in the voluntariness inquiry.
    When Juarez presented this claim in the trial court, the
    court concluded that he was not advised in a timely fashion of
    his right to have his consulate notified of his arrest under the
    Vienna Convention. (See Vienna Convention, supra, art. 36,
    par. 1(b), at p. 101 [requiring law enforcement officers to inform
    arrested foreign nationals, “without delay,” that they have the
    right to have their consulate notified of their arrest].) The court
    found that the violation was negligent, not intentional, based on
    statements by law enforcement officers and the district attorney
    that they did not know of the Vienna Convention, despite
    opportunities to learn of it. The court further concluded that the
    violation was not of constitutional dimension. The court
    declined to suppress his statements or preclude the prosecutor
    from seeking the death penalty.
    59
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    After Juarez’s trial, “the United States Supreme Court [in
    Sanchez-Llamas v. Oregon (2006) 
    548 U.S. 331
    ] made it clear
    that an officer’s failure to notify a suspect of his or her consular
    rights does not, in itself, render a confession inadmissible.”
    (People v. Enraca (2012) 
    53 Cal.4th 735
    , 756.) The California
    Legislature also enacted Penal Code section 834c, effective in
    2000, to address Vienna Convention requirements. (Stats. 1999,
    ch. 268, § 1, pp. 2338–2341.) The statute requires the police,
    upon arresting or detaining a known or suspected foreign
    national “for more than two hours,” to advise the foreign
    national of his or her consular rights but does not specify a
    remedy for violations. (§ 834c, subd. (a)(1).)
    We find no violation of section 834c since that statute was
    not effective until after Juarez’s arrest. But we proceed on the
    assumption that Juarez’s consular rights were violated by law
    enforcement’s failure to timely advise him of his right to have
    his consulate notified of his arrest under the Vienna
    Convention.
    As the high court held in Sanchez-Llamas, such a violation
    does not, by itself, require suppression. “Article 36 [of the
    Vienna Convention] has nothing whatsoever to do with . . .
    interrogations.    Indeed, Article 36 does not guarantee
    defendants any assistance at all. The provision secures only a
    right of foreign nationals to have their consulate informed of
    their arrest or detention — not to have their consulate
    intervene, or to have law enforcement authorities cease their
    investigation pending any such notice or intervention. In most
    circumstances, there is likely to be little connection between an
    Article 36 violation and evidence or statements obtained by
    police.” (Sanchez-Llamas v. Oregon, 
    supra,
     548 U.S. at p. 349;
    accord, People v. Vargas (July 13, 2020, S101247) __ Cal.5th __
    60
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    [2020 Cal. Lexis 4311, at pp. *65–67] [reversal not warranted
    “[d]espite the ‘technical violation’ of the Vienna Convention”].)
    However, “ ‘[a] defendant can raise an Article 36 claim as part
    of a broader challenge to the voluntariness of his statements to
    police.’ ” (People v. Enraca, 
    supra,
     53 Cal.4th at p. 757, quoting
    Sanchez-Llamas, at p. 331; accord, People v. Sanchez (2019)
    
    7 Cal.5th 14
    , 51.)
    Juarez does so here. Contrary to his argument, however,
    the record supports the factual finding that the violation was
    not intentional. Agent Stevens, Detective Robbins, Sergeant
    McDonald, and Detective Bennett each testified to being
    unaware of the Vienna Convention at the time of Juarez’s
    arrest. The district attorney also testified that he did not
    become aware of the advisement requirement under the Vienna
    Convention until around Juarez’s arraignment, at which time
    Juarez was advised of his rights under the Vienna Convention.
    The trial court “accept[ed] the statements of the law
    enforcement officers” and “the district attorney” that they “did
    not know of the Vienna Convention,” despite opportunities to
    learn of it. The trial court thus found that the violation of the
    Vienna Convention was negligent, not intentional. The trial
    court made that finding after assessing the credibility of
    numerous witnesses who testified about the circumstances
    surrounding the violation, and substantial evidence supports
    the finding.
    In addition, Juarez argues that the trial court failed to
    consider the violation when evaluating the validity of his waiver
    and the voluntariness of his confessions. As noted, the trial
    court found no violation of Juarez’s constitutional rights due to
    the Vienna Convention violation. The court then found “from
    the totality of the circumstances” that Juarez’s statements were
    61
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    “freely and voluntarily given after a sufficient advisement of his
    constitutional rights.” Although the court did not expressly
    refer to the Vienna Convention violation in concluding that he
    validly waived his rights and voluntarily confessed, the court
    considered “the totality of the circumstances,” and on this
    record, we decline to find error. In any event, we review
    independently whether Juarez validly waived his rights and
    voluntarily confessed. (See People v. Rundle, 
    supra,
     43 Cal.4th
    at p. 115.)
    We find that Juarez has not established a relation
    between his lack of consular notice and his confessions. (See
    People v. Leon, supra, 8 Cal.5th at p. 846.) Juarez has not shown
    that had he been advised of his consular rights earlier, he would
    have requested that the consulate be notified. Even after he was
    advised of his rights at his arraignment, he did not request such
    notification. It is true that defense counsel said she had “had
    numerous contacts” with the consulate on his behalf. And he
    submitted a declaration — which the trial court deemed not
    competent evidence in the absence of cross-examination —
    stating, among other things, “Had I known I could talk to
    someone from the Mexican Consulate, before speaking with the
    officers, I would have done so.” But his statement was largely
    “unpersuasive in view of the other evidence, because it was
    ‘conclusory, self-serving, and not subject to cross-examination.’ ”
    (U.S. v. Amano (9th Cir. 2000) 
    229 F.3d 801
    , 805.) As the trial
    court found, Juarez “readily appeared willing to talk to the
    police and to fully explain the circumstances of the crime.” We
    conclude that in the totality of the circumstances, the failure to
    timely advise him of his consular rights did not overcome his
    will and render his waiver invalid or his confessions
    involuntary. There was no error in admitting his confessions.
    62
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    C. CALJIC No. 2.28
    The Placer County District Attorney’s Office retained Dr.
    Frank Dougherty, a forensic psychologist, to observe the July
    16, 1998 interrogation live by means of a closed circuit television
    transmission. Dr. Dougherty “discussed various aspects of
    possible mental health defenses and issues regarding [Juarez]
    . . . and consulted with Deputy District Attorney Thomas
    Beattie and various sheriff’s deputies regarding interview
    techniques and anticipated prosecutorial issues related to
    [Juarez’s] actual or potentially alleged mental health.” Dr.
    Dougherty believed he took “some contemporaneous notes,” but
    he was unable to locate any notes after a “diligent” search. He
    did not provide any consultation on this case after July 16. The
    defense learned of his existence in October 2000, contacted him
    in December 2000, and interviewed him. The prosecutor
    subsequently represented that Dr. Dougherty said, “It doesn’t
    look like there’s anything wrong with him,” but the prosecutor
    was not aware of any notes taken by Dr. Dougherty.
    The defense asked the trial court to instruct the jury
    pursuant to CALJIC No. 2.28, which explained the rules of
    discovery and permitted the jury to consider failures to timely
    disclose evidence. The court denied the request. The court
    reasoned that “it’s not clear that this witness had notes,
    although he may have.” Even if he did, “it would be entirely
    speculative to assume that those notes would include anything
    that would aid the jury because those notes would only be about
    things that the jury can view through the videotape anyway, and
    thus any conjecture that this jury might enter into as to how a
    psychologist watching the interview or anybody else watching
    the interview would give additional useful information would be
    just that: conjecture.” Juarez contends that the trial court
    63
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    erred, depriving him of due process and a fair, reliable, and
    impartial determination of his guilt and sentence.
    Section 1054.1 requires the prosecutor to disclose to the
    defendant, among other things, the names, addresses, and
    “[r]elevant written or recorded statements of witnesses,” and
    “reports of the statements of witnesses whom the prosecution
    intends to call at trial, including any reports or statements of
    experts made in conjunction with the case.” (Id., subds. (a), (f).)
    When a party fails to comply with its discovery obligations, the
    trial court may, among other things, “advise the jury of any
    failure or refusal to disclose and of any untimely disclosure.”
    (Id., subd. (b).) Here, it was not clear that the prosecutor failed
    to comply with discovery obligations. The prosecutor never
    intended to call and did not call Dr. Dougherty as a witness.
    Although Dr. Dougherty “may have” taken notes, the trial court
    observed, “it’s not clear” that he did.              Under these
    circumstances, the prosecutor’s asserted failure to comply with
    discovery obligations and the trial court’s refusal to instruct the
    jury as requested did not deprive Juarez of due process or a fair,
    reliable, and impartial determination of his guilt and sentence.
    The July 16 interrogation was videotaped and played for the
    jury, and as the trial court reasoned, it is mere “conjecture” that
    any notes taken by Dr. Dougherty would have provided
    “additional useful information” to aid the jury’s own viewing of
    the videotaped interrogation.
    D. Sufficiency of Evidence for Felony Murders of
    José and Juan
    The jury was instructed that it could convict Juarez of the
    first degree murders of José and Juan based on the theories of
    premeditation and deliberation, lying in wait, or felony murder.
    The jury found him guilty of the first degree murders.
    64
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Juarez claims that there was insufficient evidence of
    felony murder, i.e., that he killed José and Juan during the
    commission of a robbery. Juarez argues that the trial court
    erred in instructing the jury as to that theory and in declining
    to provide a requested instruction concerning “independent
    felonious intent.” He emphasizes that when he moved pursuant
    to section 1118.1 for the entry of a judgment of acquittal on the
    felony-murder special circumstances regarding José and Juan,
    the court granted his motion. In considering his section 1118.1
    motion, the court indicated that it might grant the motion
    because “what was going on here was a robbery in the course of
    a murder, not a murder in the course of a robbery,” and “there
    is such a solid basis in the evidence for the multiple murder and
    lying in wait special circumstances, that it is a neater, cleaner,
    more understandable way to present to the jury the only issues
    that are really going to make much difference anyway.” The
    prosecutor did not object to the motion, and the court granted it.
    Preliminarily, we reject Juarez’s contention that the trial
    court erred in declining to provide a requested instruction
    concerning “independent felonious intent.” After the prosecutor
    argued against giving the instruction, the court questioned
    defense counsel about it, asking whether a killing that occurred
    during the commission of a robbery could support a felony
    murder conviction even if the robbery was committed for
    purposes of concealing the killing. Defense counsel essentially
    withdrew the request by responding, “I have to concede at this
    point in time that Mr. — the prosecution is correct, and I was
    thinking of something else, and unfortunately, the case law does
    not support my thought process.” The court then denied the
    request.
    65
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Even assuming the issue was preserved for review, we find
    no error. The jury was instructed that for felony murder, the
    unlawful killing must occur during the commission or attempted
    commission or as a direct causal result of the crime of robbery
    and the perpetrator must have had the specific intent to commit
    that crime. The jury was also instructed that for the crime of
    robbery, “the perpetrator must have formed the specific intent
    to permanently deprive an owner of his property before or at the
    time that the act of taking the property occurred” and “before or
    at the time of the application of force or violence, or the use of
    fear or intimidation.” Thus, “[w]ith the robbery and felony-
    murder instructions given, the jury was adequately instructed
    that [Juarez] must have possessed the intent to commit robbery
    at the time of the killing to be guilty of felony murder . . . .”
    (People v. Mora and Rangel (2018) 
    5 Cal.5th 442
    , 499.)
    As to his remaining contentions, “[w]hether we review
    [the] claim as asserted instructional error in [instructing the
    jury on a particular theory of first degree murder for which there
    was insufficient evidence] or insufficiency of the evidence
    supporting the jury’s verdict, we apply essentially the same
    standard. [Citation.] We ‘review the whole record in the light
    most favorable to the judgment below to determine whether it
    discloses substantial evidence — that is, evidence which is
    reasonable, credible, and of solid value — such that a reasonable
    trier of fact could find the defendant guilty beyond a reasonable
    doubt.’ ” (People v. Nelson (2016) 
    1 Cal.5th 513
    , 550.)
    “Robbery is defined as ‘the felonious taking of personal
    property in the possession of another, from his person or
    immediate presence, and against his will, accomplished by
    means of force or fear.’ (§ 211.) Robbery requires the ‘specific
    intent to permanently deprive’ the victim of his or her property.”
    66
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    (People v. Mora and Rangel, supra, 5 Cal.5th at p. 489.)
    “Liability for first degree murder based on a felony-murder
    theory is proper when the defendant kills in the commission of
    robbery, burglary, or any of the other felonies listed in section
    189. . . . [T]o find a defendant guilty of first degree murder
    based on a killing perpetrated during a robbery, the evidence
    must show the defendant intended to steal the victim’s property
    either before or during the fatal assault.” (People v. Lewis (2001)
    
    25 Cal.4th 610
    , 642.) “ ‘ “[T]he killing need not occur in the
    midst of the commission of the felony, so long as that felony is
    not merely incidental to, or an afterthought to, the killing.’
    [Citation.] In addition, a homicide occurs in the perpetration of
    an enumerated felony for the purpose of the felony-murder rule
    if both offenses were parts of ‘ “one continuous transaction.” ’
    [Citation.] ‘ “There is no requirement of a strict ‘causal’
    [citation] or ‘temporal’ [citation] relationship between the
    ‘felony’ and the ‘murder.’ ” ’        [Citation.]     In addition,
    ‘[c]ircumstantial evidence may provide sufficient support for a
    felony-murder conviction.’ ”         (People v. Prince (2007)
    
    40 Cal.4th 1179
    , 1259.)
    Here, there was evidence that when José and Juan arrived
    at the Parnell Ranch, José wore a watch, Juan wore gold chains,
    and both carried wallets. After their arrival, Juarez asked José
    to accompany him into the field, which he did. Y.M. did not see
    Juan. When Y.M. subsequently asked where José and Juan
    were, Juarez said that they were cleaning and cutting a deer
    that he had killed. Although there were no eyewitnesses to the
    murders, the evidence indicated that during this time, Juarez
    shot José and Juan and buried them. The following day, law
    enforcement officers discovered boots under the bed in Juarez’s
    trailer, and inside them were three metal chains, a watch, and
    67
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    two wallets containing identification for José and Juan, $147 in
    American currency, and $80 in Mexican pesos. These items did
    not have dirt on them, which suggested that the items were
    removed before placing the men in the grave. In addition, the
    clasps on the chains appeared undamaged; the jury may have
    reasonably inferred from this fact that Juarez sought to
    preserve the value of these items as opposed to hastily taking
    them as an afterthought to the murders.            Rather than
    destroying the items, Juarez also placed them within his boots
    under his bed.
    It is true that there was evidence showing that Juarez had
    planned to kill José and Juan, and when asked in the
    interrogation why Juarez took their jewelry and wallets, Juarez
    said that “[w]hen [he] saw those things it occurred to [him] to
    take it” and that he took the items because they would be able
    to identify José and Juan, not because they were valuable.
    Viewing all of the evidence in the light most favorable to the
    judgment, however, we find that a reasonable trier of fact could
    conclude that Juarez had a concurrent intent to rob and kill José
    and Juan and that the robberies were not merely incidental to,
    or an afterthought to, the murders. (Cf. People v. Brooks (2017)
    
    3 Cal.5th 1
    , 65 [“And although defendant may have intended to
    commit arson for the additional purpose of concealing [the
    victim’s] identity and his role in her killing, we have observed
    that concurrent intent to kill and to commit the target felony
    does not preclude a felony-murder theory of first degree
    murder.”].) The record discloses legally sufficient evidence of
    Juarez’s guilt of felony murder based on robbery. We further
    conclude that even though the trial court granted the
    section 1118.1 motion as to the felony-murder special
    circumstances, the felony murder theory of guilt was still
    68
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    properly before the jury, and the trial court did not err in
    instructing the jury on that theory.
    Even assuming that there was insufficient evidence to
    support the felony murder theory of guilt and that the trial court
    erred in instructing the jury on that theory, we would still
    uphold the first degree murder verdicts here. “A first degree
    murder verdict will be upheld if there is sufficient evidence as
    to at least one of the theories on which the jury is instructed,
    ‘absent an affirmative indication in the record that the verdict
    actually did rest on the inadequate ground.’ ” (People v. Nelson,
    supra, 1 Cal.5th at p. 552 [upholding first degree murder verdict
    where there was sufficient evidence of the primary prosecution
    theory of first degree murder based on premeditation and
    deliberation, even though there was insufficient evidence to
    support the theory of first degree murder based on lying in
    wait].) Juarez does not challenge the sufficiency of evidence for
    the lying-in-wait and premeditation and deliberation theories
    on which the jury was instructed. The record contains ample
    evidence in support of these theories: Among other things, he
    dug the hole in advance of their arrival, he walked José and
    Juan toward the hole after telling them that he had shot a deer
    and needed them to go to it, and he shot them in the head from
    less than an inch away. The jury found true the special
    circumstance that he killed them while lying in wait, which in
    itself makes the killing first degree murder. Accordingly, we
    uphold the first degree murder verdicts for the murders of José
    and Juan.
    E. Constitutionality of Lying-in-wait Special
    Circumstance
    Juarez claims that the lying-in-wait special circumstance
    is unconstitutional because it is vague and fails to adequately
    69
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    narrow the class of persons eligible for the death penalty. We
    have previously rejected these claims. (See, e.g., People v. Cage
    (2015) 
    62 Cal.4th 256
    , 281; People v. Lewis (2008)
    
    43 Cal.4th 415
    , 516.) He also challenges the lying-in-wait
    special-circumstance instruction, CALJIC No. 8.81.15, as
    confusing and contradictory. We have previously rejected these
    challenges. (See, e.g., People v. Cage, at pp. 280–281; People v.
    Bonilla (2007) 
    41 Cal.4th 313
    , 332–333.) Juarez provides no
    reason to revisit those decisions here.
    F. Sufficiency of Evidence for Lying-in-wait
    Special Circumstance as to J.M. and A.M.
    Juarez contends that there was insufficient evidence to
    support the jury’s finding that he killed J.M. and A.M. while
    lying in wait.
    “A sufficiency of evidence challenge to a special
    circumstance finding is reviewed under the same test applied to
    a conviction. [Citation.] Reviewed in the light most favorable to
    the judgment, the record must contain reasonable and credible
    evidence of solid value, ‘such that a reasonable trier of fact could
    find the defendant guilty beyond a reasonable doubt.’ ” (People
    v. Stevens (2007) 
    41 Cal.4th 182
    , 201.)
    At the time of the 1998 murders, “ ‘the elements of the
    lying-in-wait special circumstance required an intentional
    killing, committed under circumstances that included a physical
    concealment or concealment of purpose; a substantial period of
    watching and waiting for an opportune time to act; and,
    immediately thereafter, a surprise attack on an unsuspecting
    victim from a position of advantage. [Citations.] . . . . [The
    period of waiting and watching] need not continue for any
    particular length “ ‘of time provided that its duration is such as
    70
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    to show a state of mind equivalent to premeditation and
    deliberation.’ ” [Citation.] “ ‘ “The element of concealment is
    satisfied by a showing ‘ “that a defendant’s true intent and
    purpose were concealed by his actions or conduct. It is not
    required that he be literally concealed from view before he
    attacks the victim.” ’ ” ’ ” [Citation.] The factors of concealing
    murderous intent, and striking them from a position of
    advantage and surprise, “are the hallmark of a murder by lying
    in wait.” [Citation.]’ [Citations.] ‘[T]he lying-in-wait special
    circumstance requires “that the killing take place during the
    period of concealment and watchful waiting. . . .” [Citation.]’
    [Citation.] ‘ “During” means “at some point in the course of.” ’
    [Citation.] [¶] Moreover, when the capital crime[s] occurred, the
    lying-in-wait special circumstance required a showing that the
    defendant ‘intentionally killed the victim while lying in wait.’
    (§ 190.2, former subd. (a)(15), italics added.)” (People v. Hajek
    and Vo (2014) 
    58 Cal.4th 1144
    , 1183–1184.)
    Viewing the evidence in the light most favorable to the
    judgment, we conclude that a rational trier of fact could have
    found true this special circumstance. The record contains
    evidence that Juarez walked J.M. and A.M. approximately a
    quarter-mile to a remote location, where he had dug a hole that
    already contained the bodies of José and Juan and that was deep
    enough to hold additional bodies. “[T]he jury could reasonably
    infer that a matter of minutes elapsed” on the walk. (People v.
    Edwards (1991) 
    54 Cal.3d 787
    , 826 [substantial period of
    watching and waiting where “more than a quarter of a mile
    separated the spot where defendant first saw the girls and
    where he shot them”].) The jury could also reasonably conclude
    that he concealed his purpose as they walked. It is true that the
    children had seen him attack their mother, they had cried, and
    71
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    he had put tape on them. But Juarez said that he removed the
    tape and that the children wanted to see their father. The jury
    could reasonably infer that despite having been upset, the
    children — aged three and five — were willing to walk with
    Juarez because he was an adult with whom they were familiar.
    Juarez himself said that the children had calmed down and that
    A.M. became tired, so he let go of J.M.’s hand and carried her.
    Finally, the record contains evidence that once near the hole, he
    struck the children’s heads and put them in the hole. This is
    sufficient to infer a substantial period of watching and waiting,
    followed by a surprise attack from a position of advantage.
    G. Sufficiency of Evidence for Felony Murders of
    J.M. and A.M.
    The jury was instructed that it could convict Juarez of the
    first degree murders of J.M. and A.M. based on the theories of
    premeditation and deliberation, lying in wait, or felony murder.
    The jury found him guilty. Juarez claims, however, that there
    was insufficient evidence of felony murder — that is, that he
    killed them in the commission of the rape or penetration by a
    foreign object of Y.M. — and the trial court erred in instructing
    the jury as to that theory. He acknowledges that the felony-
    murder special circumstances as to J.M. and A.M. were
    dismissed.
    We need not decide whether sufficient evidence supported
    the theory of felony murder here. The jury’s true findings
    regarding the lying-in-wait special circumstance show that the
    jury found that Juarez killed J.M. and A.M. while lying in wait.
    Because there was sufficient evidence to support the first degree
    murder verdicts based on the lying-in-wait theory (see pt. IV(F),
    ante) and no indication that the verdicts rested on the felony
    murder theory, the verdicts must be upheld.
    72
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    H. Admission of Photographs
    The prosecutor sought to introduce 14 crime scene and 25
    autopsy photographs depicting the four murder victims. The
    defense objected to all but three of them. The trial court
    considered each photograph and excluded eight as cumulative
    or unduly prejudicial, directed the prosecutor to crop one, and
    allowed the remaining to be introduced.
    During the guilt phase, Detective Summers testified about
    the excavation of the grave and photographs depicting the
    victims within it. The photographs were displayed on a screen,
    and at times, the prosecutor enlarged parts of them. When the
    defense objected to these enlargements, the trial court directed
    the prosecutor to inform the defense before enlarging anything
    on the screen, but noted that the overhead projections were of
    “significantly lower quality than the actual photographs” and
    “there has been nothing more than a restoration on the screen”
    of the actual photographs. Dr. Henrikson also testified during
    the guilt phase about the autopsies and photographs from them.
    Juarez contends that the trial court abused its discretion
    and violated his federal constitutional rights to a fair trial, due
    process, and reliable verdicts and sentence.
    “ ‘ “This court is often asked to rule on the propriety of the
    admission of allegedly gruesome photographs. [Citations.] At
    base, the applicable rule is simply one of relevance, and the trial
    court has broad discretion in determining such relevance.” ’ ”
    (People v. Powell (2018) 
    6 Cal.5th 136
    , 163.) “ ‘ “A trial court’s
    decision to admit photographs . . . will be upheld on appeal
    unless the prejudicial effect . . . clearly outweighs their
    probative value.” ’ ” (Ibid.)
    73
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Here, the trial court exercised its discretion in excluding
    some photographs and admitting others. We have examined the
    photographs. The crime scene photographs were relevant to
    show that the murders occurred, where and how the victims
    were buried, and the order in which they were buried. (See
    People v. Cowan (2010) 
    50 Cal.4th 401
    , 475 [photographs
    showed “the locations and positions in which [the] bodies were
    found”].) The autopsy photographs were relevant to show the
    manner of the killings and to clarify testimony regarding the
    victims’ injuries and causes of death. (Ibid.) Although the
    photographs were numerous, “none gratuitously duplicated any
    other.” (People v. Memro (1995) 
    11 Cal.4th 786
    , 867; see People
    v. Panah, 
    supra,
     35 Cal.4th at pp. 476–477 [no abuse of
    discretion for admitting eight photographs of victim]; People v.
    Crittenden (1994) 
    9 Cal.4th 83
    , 131–135 [no abuse of discretion
    for admitting 24 photographs of two victims].)
    Nor were the photographs “ ‘so gruesome as to have
    impermissibly swayed the jury.’ ” (People v. Burney (2009)
    
    47 Cal.4th 203
    , 243.) The excavators proceeded carefully in an
    effort to preserve and photograph the original positions of the
    bodies. Similarly, the autopsy photographs did not contain
    gratuitous details. Contrary to Juarez’s argument, they were
    wholly unlike the autopsy photographs in People v. Marsh
    (1985) 
    175 Cal.App.3d 987
    , 996–999, which were “gruesome
    solely because of the autopsy surgeon’s handiwork; removing the
    skull, opening the body cavity, covering the child’s face with the
    exposed underside of the bloody scalp, etc.” We conclude the
    trial court did not abuse its discretion or violate Juarez’s
    constitutional rights.
    74
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    I. Prosecutorial Misconduct
    Juarez contends that the prosecutor committed
    misconduct by eliciting inadmissible and prejudicial testimony.
    This misconduct, he contends, violated his rights to due process
    and a reliable guilt and penalty determination.
    1. Testimony by Deputy Walker
    While discussing motions in limine, defense counsel noted
    that a responding officer had described “[Y.M.] running her
    finger across her neck in a gesture,” but defense counsel did not
    believe that the prosecutor intended to introduce this evidence.
    The court said, “Well, let’s — why don’t we deal with this
    whenever you think it first needs to come up.” The prosecutor
    said, “That’s fine, Your Honor.”
    During the guilt phase, Deputy Walker testified about
    talking to Y.M. on the night of the crimes. He asked her whether
    she had been tied up. When the prosecutor asked about her
    response, the defense objected on hearsay grounds, but the court
    overruled the objection. Deputy Walker testified, “I don’t
    remember if I got a response in regards to the duct tape, but I
    do remember regards [sic] to the scarf that was around her
    neck.” The prosecutor asked, “Did she physically manipulate or
    move the scarf in some fashion in response to your question?” to
    which Deputy Walker replied affirmatively. The prosecutor
    then asked, “How did she do that?” Deputy Walker replied, “She
    took the scarf, put it in her mouth and said, ‘Arturo bad,’ ” and
    Deputy Walker made a “grating noise” and “dr[ew] his right
    index finger across his neck.”
    The defense objected and, outside the presence of the jury,
    moved for a mistrial, arguing that the gesture and noise were
    hearsay, prejudicial, and conveyed that Y.M. wanted Juarez to
    75
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    be killed. Although opposing this, the prosecutor described the
    gesture as Y.M. “expressing anger regarding [Juarez] and
    perhaps a desire to get even for what has occurred.”
    The trial court urged counsel to remember “those matters
    with respect to which there are in limine orders in place and
    which have not been ruled on,” and observed that defense
    counsel “did what he needed to do in order to assure that he
    could get a ruling on this evidence before the jury heard it.” The
    court, however, denied the motion for a mistrial. The court
    concluded that the gesture fell within the hearsay exception for
    excited utterances and carried “little, if any,” prejudice. The
    court explained that the gesture was “highly ambiguous.” “[I]t
    is extraordinarily unlikely that what [Y.M.] was trying to convey
    was [Juarez] has done a terrible thing and should receive the
    death penalty.” Instead, “it is highly likely what she was trying
    to convey is yes, I had some kind of a binding of some sort around
    my neck,” or at most, “an expression of undifferentiated
    outrage.” The court also denied the defense’s request to
    admonish the jury to disregard Deputy Walker’s testimony,
    without prejudice to the defense later requesting an instruction
    that the jury should disregard any victim’s views on how this
    case should be resolved.
    “ ‘ “A prosecutor’s . . . intemperate behavior violates the
    federal Constitution when it comprises a pattern of conduct ‘so
    egregious that it infects the trial with such unfairness as to
    make the conviction a denial of due process.’ ” ’ [Citations.]
    Conduct by a prosecutor that does not render a criminal trial
    fundamentally unfair is prosecutorial misconduct under state
    law only if it involves ‘ “ ‘the use of deceptive or reprehensible
    methods to attempt to persuade either the court or the jury.’ ” ’ ”
    (People v. Samayoa (1997) 
    15 Cal.4th 795
    , 841.) “ ‘ “It is, of
    76
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    course, misconduct for a prosecutor to ‘intentionally elicit
    inadmissible testimony.’     [Citations.]”   [Citation.] Such
    misconduct is exacerbated if the prosecutor continues to elicit
    such evidence after defense counsel has objected.’ [Citation.]
    However, a prosecutor cannot be faulted for a witness’s
    nonresponsive answer that the prosecutor neither solicited nor
    could have anticipated.” (Tully, supra, 54 Cal.4th at p. 1035;
    People v. O’Malley (2016) 
    62 Cal.4th 944
    , 998.)
    Whether the prosecutor, in asking Deputy Walker how
    Y.M. physically manipulated or moved the scarf, could have
    anticipated the testimony about her gesture and noise presents
    a close issue. The prosecutor did not directly ask whether she
    made a gesture or a noise, although defense counsel had alerted
    the prosecutor to the issue and the trial court had expressly
    reserved the issue. But even assuming the prosecutor elicited
    this testimony in violation of the court’s request to rule on it, the
    prosecutor’s “asking of a single question” did not constitute a
    “pattern of conduct so egregious that it rendered the trial
    fundamentally unfair.” (People v. Cox (2003) 
    30 Cal.4th 916
    ,
    952.) Nor did the prosecutor’s conduct cause prejudice at the
    guilt phase or the penalty phase of the trial. The gesture and
    noise were a brief and passing element of a lengthy trial, with
    little if any prejudicial weight in comparison to the totality of
    other evidence. We find no prejudicial misconduct or trial court
    error.
    2. Testimony by Orozco
    The trial court ordered that “no other crimes evidence, no
    character evidence, and no reputation evidence be introduced
    during the guilt phase,” without a court order. Before Orozco
    77
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    testified, the prosecutor stated that he no longer intended to
    introduce testimony about Juarez’s womanizing.
    During Orozco’s testimony, the prosecutor asked whether
    he recalled “anything [Juarez and he] talked about on the way
    back” after visiting the Martinezes.            Orozco replied
    affirmatively. The prosecutor asked, “And what was that?”
    Orozco responded in Spanish, but the interpreter did not
    translate his response in the jury’s presence. Outside the jury’s
    presence, the interpreter translated his response: “ ‘He was
    talking to me about being with a girl in Santa Gertrudis.’ ”
    The defense moved for a mistrial, arguing that the
    prosecutor violated his representation regarding Orozco’s
    testimony. The court denied the motion but agreed to strike
    Orozco’s response and instruct the jurors that to the extent they
    understood it, they should disregard it.
    Shortly after resuming, the prosecutor asked Orozco
    whether Juarez said anything about the Martinezes on the
    drive. Orozco responded no, and further testified that Juarez
    did not mention being threatened by José or Juan.
    There was no misconduct. Although the prosecutor asked
    an open-ended question, it is not clear that the prosecutor
    solicited or anticipated Orozco’s response. And even if we
    assume that the prosecutor did anticipate Orozco’s response, it
    did not render the trial fundamentally unfair or cause prejudice.
    The response was brief and stated in Spanish, and the court
    struck it and instructed the jury to disregard it.

    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    V. PENALTY PHASE ISSUES
    A. Denial of Discovery Motion Regarding
    Discriminatory Prosecution
    Juarez contends that the trial court erred in denying his
    motion for discovery to pursue a claim of discriminatory
    prosecution by the Placer County District Attorney’s Office
    (District Attorney). He asks us to remand the case to the trial
    court to consider his claim of discriminatory prosecution after
    he receives discovery.
    “ ‘[D]iscriminatory enforcement of the laws may be a valid
    defense in a case in which the [defense] can establish deliberate
    invidious discrimination by prosecutorial authorities.’
    [Citation.]. . . .   In Murgia[ v. Municipal Court (1975)]
    15 Cal.3d [286, 306], we held that when a defendant seeks to
    defend a criminal prosecution based on discriminatory
    prosecution, ‘traditional principles of criminal discovery
    mandate that defendants be permitted to discover information
    relevant to such a claim.’ ”         (People v. Montes (2014)
    
    58 Cal.4th 809
    , 828.) “Under our state law standard, a Murgia
    motion must ‘ “describe the requested information with at least
    some degree of specificity and must be sustained by plausible
    justification.” ’ [Citation.] We have held a showing of ‘plausible
    justification’ requires a defendant to ‘show by direct or
    circumstantial evidence that prosecutorial discretion was
    exercised with intentional and invidious discrimination in his
    case.’ [Citation.] Similarly, under the federal standard, a
    defendant must produce ‘ “some evidence” ’ tending to show the
    existence of both a discriminatory effect and the prosecutor’s
    discriminatory intent.” (Id. at p. 829.) On appeal, we assume
    that the motion was validly made and consider “whether
    79
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    defendant made the requisite showing under state or federal
    standards to obtain the discovery he sought.” (Ibid.)
    Juarez argues that he made the requisite showing based
    on two facts alleged in his motion. First, since 1977, there were
    only three other cases involving multiple murders and murders
    of children; the defendants (James Hill, Kenneth McGraw,
    Theresa Knorr) were Caucasian and were offered plea bargains.
    Second, in the preceding decade, the District Attorney sought
    the death penalty at trial against only two defendants, both of
    whom were African American.
    The Attorney General argues that Juarez failed to make
    the requisite showing and relies on additional facts identified by
    the District Attorney. First, the cases against Hill, McGraw,
    and Knorr were distinguishable. Hill had been admitted to a
    mental hospital before killing his two children; McGraw had
    been found incompetent to stand trial for killing his pregnant
    estranged wife and daughter, and a key prosecution witness had
    died before McGraw’s criminal proceedings resumed; and
    Knorr’s case had been transferred to another county, where the
    District Attorney did not participate. Second, Juarez’s date
    range for death penalty trials was arbitrary and misleading.
    Based on the prosecutor’s “personal knowledge of the cases, [his]
    personal review of court files, and on [his] direct communication
    with [deputy district attorneys],” the District Attorney charged
    46 defendants (of whom 26 were White, 19 were persons of color,
    and one was of unknown ethnicity) with special circumstances
    between 1977 and 2000, and sought the death penalty at trial
    against eight of them, of whom five were White, two were
    African American, and one was of unknown ethnicity.
    80
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    The trial court denied the motion after finding no showing
    of discriminatory effect or discriminatory intent based on a case-
    by-case analysis or a statistical analysis. The court noted that
    no case in the county’s history involved the “degree of criminal
    conduct in terms of multiple homicides and sexual assault” as
    existed here.
    We see no error. Juarez’s case-by-case analysis boils down
    to merely two cases, both of which involved fewer murders and
    no rape allegations. Neither comparison is persuasive. In
    addition, his statistics about the District Attorney seeking the
    death penalty at trial “failed to take into account the case
    characteristics of the homicides” and used an arbitrary date
    range, as suggested by the District Attorney’s additional
    information in this regard. (People v. Montes, supra, 58 Cal.4th
    at pp. 830–831.) Juarez has not made the requisite showing.
    B. Use of Jail Visitation Logs
    Before trial, the prosecutor’s investigator reviewed
    Juarez’s jail visitation logs and contacted persons listed on
    them. Juarez contends that this conduct violated his statutory
    and constitutional rights and urges us to set aside his
    convictions and sentence.
    1. Background
    In December 1999, defense counsel learned that the
    prosecutor’s investigator, Joe Bertoni, had contacted two of its
    experts. The defense filed an emergency application to restrain
    the prosecutor from accessing the identities of defense experts
    or contacting them, and to order the prosecutor to disclose all
    defense experts of whom they had become aware or whom they
    had contacted and the source of that information. At a
    December 13, 1999 hearing, the defense explained that the
    81
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    prosecutor had obtained the information from jail visitation
    logs. The trial court ordered the prosecutor to provide the
    defense with copies of the jail visitation logs, a list of all persons
    contacted from them, and a summary of all information
    obtained. The court also ordered the prosecutor not to review
    the logs or contact persons on them and not to disclose
    information obtained to the Attorney General, pending a further
    hearing.     The defense subsequently moved to estop the
    prosecutor from seeking the death penalty, to recuse the District
    Attorney, and to require the prosecutor to demonstrate that no
    part of its case relied on information thus obtained.
    At the hearing in January 2000, the acting corrections
    support supervisor, Donna Sylvia, testified that the jail
    maintains visitation logs for security reasons but routinely
    provides them to law enforcement. The logs contain the date
    and time of each visit, classify the visit as either personal or
    professional, and contain a remarks field that typically lists the
    visitor’s name, contact information, and relationship (if
    personal) or occupation (if professional). The logs typically do
    not contain the purpose of the visits, although a clerk could
    enter that information in the remarks field. For example, the
    log refers once to “psych eval” in the remarks field.
    Bertoni testified that he routinely reviewed visitation logs
    in his investigations to identify potential witnesses and was not
    aware of any rule prohibiting such review. He accessed the logs
    in Juarez’s case through his network terminal on two occasions
    (once in 1998 and again around July 1999), and due to a system
    change, he requested and received them through the jail records
    custodian on a third occasion (around Sept. or Oct. 1999). On
    that third occasion, he requested them after being asked to do
    so in a memorandum by Deputy District Attorney Peggy Turner,
    82
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    who indicated she acted on behalf of Deputy District Attorney
    Thomas Beattie. The memorandum asked Bertoni to review the
    logs and gather information about professionals listed in them,
    including whether, where, and what they had previously
    testified.
    Bertoni testified that in reviewing the logs, he identified
    personal visitors who might lead to additional interviews and
    sought information about professional visitors. He contacted
    four of the personal visitors as part of his “continuing
    investigation.”    He searched the Internet and contacted
    associations in regard to two professional visitors; from this, he
    learned that one of the professionals had testified in Sonoma
    County. He then called the two professionals, identified himself,
    said that they might be witnesses in this case, and asked for
    their curricula vitae and experience testifying. One of the
    professionals agreed to provide her curriculum vitae and said
    that she had testified approximately “40/60” for the prosecution
    and the defense but did not clarify to which side the percentages
    corresponded. Bertoni testified that he did not recall but may
    have referred to the other professional by name in his call with
    her. Bertoni did not ask about their conversations with Juarez,
    and no confidential communications were divulged. He provided
    the information he collected to Turner and Beattie.
    Following the hearing, the trial court concluded that the
    prosecutor did not violate any express statutory provision, but
    the court made note of section 987.9, which authorizes a capital
    defendant to “request the court for funds for the specific
    payment of investigators, experts, and others for the
    preparation or presentation of the defense,” and provides that
    “[t]he fact that an application has been made shall be
    confidential and the contents of the application shall be
    83
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    confidential.” In order to facilitate section 987.9’s purpose and
    spirit, and to permit the defense to prepare its case in an
    atmosphere of confidentiality, the court ordered the jail not to
    disclose, and the District Attorney not to obtain, any
    information pertaining to the defense expert witnesses in the
    case unless an exception applied. “Expert witnesses” for
    purposes of this order meant persons retained by the defense
    pursuant to section 987.9. The court declined to preclude the
    prosecutor from seeking the death penalty or to recuse the
    District Attorney because the court found the defense had failed
    to establish the necessity of either sanction. The court found no
    showing of material prejudice. The court declined to speculate
    that the prosecutor held the key to the defense’s case based on
    the names of two potential experts. The court reasoned that the
    information about the two experts would have been
    subsequently disclosed to the prosecutor or would have been
    rendered irrelevant. The court noted that “[t]here may well be
    other tactical arguments or information that might be gleaned
    from the presence or absence of any particular witness,” but in
    the very early stage of the trial preparation process here, the
    court was “only given the possibility of prejudice without any
    actual showing of prejudice.”
    Several months later, the defense renewed its motion to
    estop the prosecutor from seeking the death penalty and to
    recuse the District Attorney. The defense claimed that the
    prosecutor improperly contacted the California Medical
    Forensic Group (CMFG), which provided medical and mental
    health care to inmates, and learned that Juarez’s file did not
    contain any psychotherapist records. The defense argued that
    the prosecutor sought this information to determine whether
    there was any medical or mental condition that might bear on
    84
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    the Miranda issues or on the mitigating evidence at the penalty
    phase. The prosecutor responded that he had contacted CMFG
    because he had issued a subpoena and did not want to
    inadvertently receive materials subject to the psychotherapist
    privilege. The trial court denied the motion. The court
    characterized the prosecutor’s conduct as “probably ill advised”
    and “probably improper” but “an honest attempt to avoid
    problems of getting information they didn’t have a right to.” The
    court subsequently ruled that the prosecution could not
    introduce Juarez’s jail medical records in its case-in-chief.
    2. Discussion
    Juarez seems to agree with the Attorney General that a
    prosecutor can access jail visitation logs for purposes other than
    gathering information about a defendant’s possible defenses.
    (Cf. People v. Loyd (2002) 
    27 Cal.4th 997
    , 1010 [“California law
    now permits law enforcement officers to monitor and record
    unprivileged communications between inmates and their
    visitors to gather evidence of crime”].) He focuses his claim on
    the prosecutor’s use of the jail visitation logs to obtain
    information about defense experts. He contends that this
    conduct violated state statutes and his constitutional right to
    counsel, his right against self-incrimination, and his rights to
    due process and equal protection. He also asserts with little
    analysis that this conduct violated Evidence Code section 1017
    and his rights to be free of unreasonable searches and seizures
    and to privacy and association.
    We begin with Juarez’s statutory claims. Civil Code
    section 1798.24 of the Information Practices Act of 1977 (Civ.
    Code, § 1798 et seq.) prohibits agencies from disclosing
    “personal information in a manner that would link the
    85
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    information disclosed to the individual to whom it pertains,”
    absent an exception.        Subdivision (e), however, permits
    disclosing information to another agency when the disclosure is
    necessary for the agency to perform its duties and “the use is
    compatible with a purpose for which the information was
    collected.” (Civ. Code, § 1798.24, subd. (e).) When information
    is transferred to or from a law enforcement agency, “a use is
    compatible if the use of the information requested is needed in
    an investigation of unlawful activity under the jurisdiction of
    the requesting agency.” (Ibid.) Subdivision (o) additionally
    permits disclosing information “[t]o a law enforcement or
    regulatory agency when required for an investigation of
    unlawful activity” unless the disclosure is otherwise prohibited
    by law. (Civ. Code, § 1798.24, subd. (o).) Information that is
    permitted to be disclosed under subdivision (e) or subdivision (o)
    “shall be provided when requested by a district attorney.” (Civ.
    Code, § 1798.68.) Because the Information Practices Act of 1977
    provides that information required for an investigation of
    unlawful activity “shall be provided” to a district attorney upon
    request, we do not find a violation of this statute by the
    prosecutor’s access to the jail visitation logs here.
    Section 987.9 provides that in a capital case trial, “the
    indigent defendant, through the defendant’s counsel, may
    request the court for funds for the specific payment of
    investigators, experts, and others for the preparation or
    presentation of the defense.” (§ 987.9, subd. (a).) “The fact that
    an application has been made shall be confidential and the
    contents of the application shall be confidential.” (Ibid.) In light
    of section 987.9’s directive that not only the contents of a defense
    application for payment of experts but also the mere “fact that
    an application has been made” “shall be confidential,” we find it
    86
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    troubling that the prosecutor in this case directed the
    investigator to review the visitation logs for the purpose of
    learning about the defense’s possible experts. Through these
    efforts, the prosecutor learned about two experts who were
    consulted but who ultimately did not testify. In other words, the
    prosecutor’s purpose was to learn — and he in fact did learn —
    what he could about the defense plans from whatever could be
    gleaned from the identities of the defense’s possible experts.
    Although section 987.9 does not expressly make confidential the
    fact that a defense expert visited a defendant in jail, the
    prosecutor’s conduct is difficult to square with the evident
    purpose of section 987.9. (See People v. Berryman (1993)
    
    6 Cal.4th 1048
    , 1071 [“ ‘The confidentiality requirement was
    evidently intended to prevent the prosecution from learning of
    the application for funds and thereby improperly anticipating
    the accused’s defense.’ ” (italics added)].)
    However, even if we find the prosecutor’s learning about
    the defense’s possible experts to be an improper invasion of
    Juarez’s statutory entitlement to confidentiality in consulting
    defense experts, we cannot reverse the judgment unless we find
    it “reasonably probable that a result more favorable to [the
    defendant] would have been reached” at the guilt phase in the
    absence of the prosecutor’s conduct (People v. Watson (1956)
    
    46 Cal.2d 818
    , 836) or that there is “a reasonable (i.e., realistic)
    possibility that the jury would have rendered a different verdict”
    at the penalty phase in the absence of the prosecutor’s conduct
    (People v. Brown (1988) 
    46 Cal.3d 432
    , 448). Here, neither the
    prosecutor nor the investigator sought to learn, or actually
    learned, of any conversations among Juarez, the experts, and
    defense counsel. The circumstances here differ from those in
    Morrow v. Superior Court (1994) 
    30 Cal.App.4th 1252
    , 1261,
    87
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    where the prosecutor “orchestrate[d] an eavesdropping upon a
    privileged attorney-client communication in the courtroom and
    acquire[d] confidential information.”      (Ibid. [dismissal is
    appropriate because there was a “ ‘substantial threat of
    demonstrable prejudice’ ” as a matter of law].)
    Further, the record does not show that the conduct aided
    the prosecution or harmed the defense. The trial court, alert to
    the confidentiality guarantee in section 987.9, restricted the
    prosecution’s access to information about defense experts in
    December 1999, approximately 15 months before trial. There is
    no showing of specific insights that the prosecutor divined about
    defense strategy before then. And neither the Attorney General
    nor Juarez identify any specific evidence offered by the
    prosecution that was developed as a result of the visitation logs.
    Nor has Juarez pointed to any specific evidence that the defense
    chose not to present as a result of the prosecutor’s conduct.
    Juarez also has not shown that the prosecutor’s conduct actually
    impaired Juarez’s ability to consult with counsel or any expert,
    or his ability to otherwise assist in his defense. We conclude
    that, despite the impropriety of the prosecutor’s conduct,
    reversal on statutory grounds is unwarranted.
    We further reject Juarez’s related assertion that the
    attorney-client and work-product privileges were violated. None
    of the information obtained from the visitation logs constituted
    “a confidential communication between client and lawyer.”
    (Evid. Code, §§ 952, 954.) Nor did the information constitute
    attorney work-product material — that is, “ ‘ “any writing
    reflecting ‘an attorney’s impressions, conclusions, opinions, or
    legal research or theories.’ ” ’ ” (People v. Zamudio (2008)
    
    43 Cal.4th 327
    , 355; see id. at p. 355, fn. 14.)
    88
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    We next consider whether the prosecutor’s conduct
    violated Juarez’s right to counsel under article I, section 15 of
    the California Constitution. In Barber v. Municipal Court
    (1979) 
    24 Cal.3d 742
    , 745 (Barber), we considered the proper
    remedy when an accused’s constitutional right to counsel has
    been denied by the actions of an undercover police officer who
    posed as a codefendant and attended the accused’s confidential
    attorney-client conferences. We held that the right to counsel
    guaranteed by the Constitution “embodies the right to private
    consultation with counsel” and “is violated when a state agent
    is present at confidential attorney-client conferences.” (Id. at
    p. 752.) Rejecting an exclusionary remedy, we concluded the
    appropriate remedy was dismissal of the charges. (Id. at
    pp. 759–760.)
    We distinguished Barber in People v. Alexander (2010)
    
    49 Cal.4th 846
     (Alexander), where we emphasized that “the
    officer in Barber participated in many meetings during which
    defense strategy was thoroughly discussed; he conveyed, to some
    degree, the nature of the anticipated defense with his superiors;
    and he inserted himself directly into the defense preparations
    . . . . All of this occurred because the officer, with the knowledge
    of the prosecution, deceived the defendant and their attorneys
    concerning his true status. [Citation.] In addition, there was
    evidence that the defendants ‘[had] been prejudiced in their
    ability to prepare their defense’ after they learned an
    undercover officer had been in their midst.” (Id. at p. 895.) In
    Alexander, “detectives intercepted one telephone call between
    defendant and a defense investigator that covered only limited
    topics related to certain witnesses, and the interception occurred
    pursuant to a judicially approved warrant, not ‘trickery’ by the
    authorities. There was no evidence anyone other than the
    89
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    officers monitoring the call learned of its contents, and much of
    what was discussed in that call was repeated in subsequent calls
    that were not privileged.” (Ibid.) On these facts, we declined to
    decide whether the defendant’s state constitutional right to
    counsel was violated; we instead concluded that reversal was
    not warranted even assuming a violation. (Ibid.) Finding “[n]o
    evidence establish[ing] that the prosecution gained anything
    from intercepting the call or that the defense was affected
    negatively in a way that could have changed the trial’s
    outcome,” we concluded that the defendant had not shown “a
    reasonable probability” of prejudice. (Id. at p. 899.)
    Similarly here, even assuming Juarez’s state
    constitutional right to counsel was violated, there is no
    reasonable probability or possibility that absent the violation, a
    result more favorable to him would have been reached at either
    the guilt or the penalty phase of the trial. In this case, unlike in
    Barber, no state agent attended confidential attorney-client
    conferences, and all attorney-client communications remained
    confidential. Moreover, as noted, neither the investigator nor
    the prosecution learned the content of any conversations
    between Juarez and the experts, and the record does not show
    that the prosecutor’s conduct impaired the preparation of his
    defense or aided the state’s presentation of the evidence against
    him.
    We turn now to Juarez’s claim that the prosecutor’s
    conduct violated his right to counsel under the Sixth
    Amendment. “In Weatherford v. Bursey (1977) 
    429 U.S. 545
    ,
    549 [
    51 L.Ed.2d 30
    , 
    97 S.Ct. 837
    ] (Weatherford) the Supreme
    Court rejected a per se rule that ‘ “whenever the prosecution
    knowingly arranges and permits intrusion into the attorney-
    client relationship the right to counsel is sufficiently endangered
    90
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    to require reversal and a new trial.” ’ Although the high court
    did not establish a definitive standard for determining when
    surreptitious state participation in communications between a
    defendant and his or her attorney or . . . the attorney’s agent,
    does violate the Sixth Amendment, it stated that unless the
    record supports ‘at least a realistic possibility of injury to [the
    defendant] or benefit to the State, there can be no Sixth
    Amendment violation.’ [Citations.] In other words, a court
    properly rejects a Sixth Amendment claim based on
    surreptitious state participation in communications between a
    defendant and his or her attorney or the attorney’s agent when
    the record demonstrates there was no realistic possibility of
    injury to the defendant or benefit to the prosecution.”
    (Alexander, supra, 49 Cal.4th at pp. 888–889.)
    Weatherford was an undercover law enforcement agent
    who, along with Bursey and two others, vandalized an office.
    Bursey was arrested and charged, and Weatherford, in order to
    maintain his undercover status, was fictitiously arrested and
    charged as well. Weatherford was invited to two meetings with
    Bursey and his attorney Wise to discuss defense tactics.
    Weatherford did not share any information he obtained from
    those meetings. But he did testify at Bursey’s trial regarding
    his undercover activities and the vandalism. After Bursey was
    convicted, Bursey initiated a civil rights action against
    Weatherford and others, alleging a deprivation of his Sixth
    Amendment right to the assistance of counsel. (Weatherford v.
    Bursey, 
    supra,
     429 U.S. at pp. 547–549 (Weatherford).)
    The high court observed that Weatherford’s testimony did
    not reveal anything about the meetings, that none of the state’s
    evidence was obtained as a result of his participation in the
    meetings, and that the district court found that Weatherford did
    91
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    not communicate about the meetings to his superiors or to the
    prosecution. (Weatherford, 
    supra,
     429 U.S. at pp. 555–556.)
    “Moreover, this is not a situation where the State’s purpose was
    to learn what it could about the defendant’s defense plans and
    the informant was instructed to intrude on the lawyer-client
    relationship or where the informant has assumed for himself
    that task and acted accordingly.” (Id. at p. 557.) “There being
    no tainted evidence in this case, no communication of defense
    strategy to the prosecution, and no purposeful intrusion by
    Weatherford,” the Sixth Amendment was not violated. (Id. at
    p. 558.)
    We applied Weatherford in People v. Ervine (2009)
    
    47 Cal.4th 745
     (Ervine). There, the trial court found that jail
    personnel had read defendant’s privileged materials during a
    search of his cell, but no privileged information had been
    communicated to the prosecution.        We found no Sixth
    Amendment violation in the absence of evidence that
    confidential information was conveyed to the prosecution. (Id.
    at pp. 763–765, 768.)
    We again applied Weatherford in Alexander, where the
    defendant challenged the recording of a telephone call involving
    himself, his mother, and a defense investigator. We said the
    “critical facts are comparable [to those in Weatherford] in all
    important respects.” (Alexander, supra, 49 Cal.4th at p. 889.)
    “In both cases a law enforcement officer who was assisting in the
    investigation of the defendant’s offenses, and who testified at
    the defendant’s trial, became privy to trial strategy discussions
    between the defendant and the defense attorney or the
    attorney’s agents. In both, the record supported the findings
    that the information the officer learned was not conveyed to the
    prosecutors and that the officer’s investigation or testimony at
    92
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    trial was not affected by information learned during the
    discussions.” (Ibid.) Neither case was “ ‘a situation where the
    State’s purpose was to learn what it could about the defendant’s
    defense plans.’ ” (Id. at p. 890.) We also noted that the
    “defendant’s mother repeated to others much of what was
    discussed during the three-way call” and that the prosecutors
    therefore “would have learned much of its contents,” further
    decreasing “any possibility that interception of the call hindered
    the defense or benefited the prosecution.” (Id. at pp. 889–890.)
    We thus concluded “the record demonstrates no realistic
    possibility that defendant was injured by, or the prosecution
    benefited from, the monitoring and recording of the three-way
    call” and, accordingly, there was no Sixth Amendment violation.
    (Id. at p. 891.)
    Here, unlike in Weatherford, Ervine, and Alexander, the
    prosecutor purposefully instructed the investigator to review
    the visitation logs in order to learn about possible defense
    experts. And the investigator did learn confidential information
    — namely, the identities of two defense experts — and
    proceeded to research the background and qualifications of
    those experts, presumably to gain insight into the defense plan.
    This conduct improperly invaded the confidentiality to which
    Juarez was entitled in preparing his defense. Nevertheless, the
    prosecutor did not learn the content of any conversation between
    Juarez and the experts, and the Attorney General and Juarez
    do not point to any trial evidence that was derived or developed
    from the investigator’s access to the visitation logs, nor does
    Juarez identify any evidence he would have developed or
    presented had the improper access not occurred. For these
    reasons and others stated above, we conclude that “the record
    demonstrates no realistic possibility that defendant was injured
    93
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    by, or the prosecution benefited from,” the investigator’s access
    to the visitation logs, and we thus find no Sixth Amendment
    violation. (Alexander, 
    supra,
     49 Cal.4th at p. 891.)
    Juarez additionally asserts a violation of his Fifth
    Amendment right against self-incrimination.            The Fifth
    Amendment “prohibits the direct or derivative criminal use
    against an individual of ‘testimonial’ communications of an
    incriminatory nature, obtained from the person under official
    compulsion.” (People v. Low (2010) 
    49 Cal.4th 372
    , 390.) Juarez
    notes that the experts signed into the jail, but he identifies no
    statement obtained by compulsion and personal to him, much
    less used against him at trial. (See Maldonado v. Superior Court
    (2012) 
    53 Cal.4th 1112
    , 1127 [“this constitutional provision
    simply bars the direct or derivative use of such officially
    compelled disclosures to convict or criminally punish the person
    from whom they were obtained”]; cf. Izazaga v. Superior Court
    (1991) 
    54 Cal.3d 356
    , 367–369 [statements of witnesses are not
    personal to the defendant and therefore fall outside this clause].)
    His claim therefore fails.
    Juarez’s asserted violation of his due process rights fares
    no better. He claims that the prosecutor’s use of the logs
    “disrupt[ed] the reciprocity mandated by the due process clause”
    because the defense did not have access to the logs or
    comparable access to information about prosecution experts.
    “However, as we have explained, because the concern of the due
    process clause is ‘the right of the defendant to a fair trial,’ the
    focus of the reciprocity inquiry under the due process clause is
    whether any lack of reciprocity ‘ “interferes with the defendant’s
    ability to secure a fair trial.” ’ ” (People v. Valdez (2012)
    
    55 Cal.4th 82
    , 120.) To the extent there was any lack of
    reciprocity here, it did not compromise his ability to present a
    94
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    defense or tilt the balance toward the state to any significant
    degree.
    Nor do we find merit in his undeveloped equal protection
    argument. Juarez contends that the prosecutor could access the
    identities of possible defense experts only because he was
    incarcerated and not released on bail. But he offers no reason
    why the state may not require persons visiting an incarcerated
    defendant to identify themselves to prison authorities, even
    though persons visiting a defendant who is not incarcerated
    need not.
    Finally, as to the prosecutor’s contact with CMFG, Juarez
    argues that the prosecutor learned from CMFG “what it needed
    to know about any evidence of mental conditions that [Juarez]
    might use during pretrial motions, or at a penalty phase,” and
    he asserts with little analysis that this interfered with the
    development of a defense and violated his right against self-
    incrimination, to equal protection, and to a fair trial. The
    prosecutor’s inquiry into the existence of an inmate’s
    psychotherapy records is also troubling. (See Evid. Code,
    § 1017, subd. (a) [psychotherapist-patient privilege applies
    “where the psychotherapist is appointed by order of the court
    upon request of” defense counsel in order to advise a criminal
    defendant on presenting a defense based on his or her emotional
    or mental condition].) But the trial court prohibited the
    prosecutor from introducing Juarez’s jail medical records. For
    this reason, and for the reasons discussed above, the
    prosecutor’s conduct did not violate these constitutional rights
    or deprive Juarez of a fair trial.
    95
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    C. Denial of Motion for a Mistrial Following Y.M.’s
    Testimony
    Juarez contends that the trial court erred in denying his
    motion for a mistrial after Y.M. testified. Her testimony, he
    argues, was so inflammatory that it deprived him of the jury’s
    reasoned moral response and violated his rights to due process,
    a fair trial, and a reliable penalty determination.
    Y.M. testified about the victims’ personal characteristics
    and the emotional and financial impact of their deaths on her.
    During her testimony, two photographs of the victims and a
    short videotape of the children were displayed. At one point, the
    prosecutor asked how she felt when she thought about her
    children these days. She responded, “I feel a lot of pain for not
    having been able to do anything for them. I wish I could turn
    time back and give my life for them. I still remember the day
    when I was being beaten, and the thing that terrifies me the
    most is having been unable to do anything for them. Their little
    faces. Their desperation at seeing how their mother was being
    beaten, and me unable to do a thing for them.” Following her
    response, the court recessed.
    Once her testimony concluded, the defense moved for a
    mistrial. The defense argued that Y.M.’s testimony was so
    emotionally charged that it was impossible for the jury to make
    a dispassionate decision about life or death. The defense also
    argued that when she left the courtroom during the recess, she
    cried “very loudly” in the hallway. Although the trial judge did
    not hear her crying, the prosecutor and the courtroom deputy
    did, but when the deputy went into the hallway, he found her
    quiet and no jurors present. The court denied the motion,
    stating that at the end of the morning, “when [Y.M.] was
    describing the helplessness she felt as she saw her children’s
    96
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    fear for her, she began to cry uncontrollably.” Her emotionalism
    lasted “about half a minute,” and the court recessed. She was
    “remarkably composed throughout most of her testimony.” She
    became “slightly tearful” on one or “[p]erhaps more than one
    other occasion” but “not to a point where, other than to cause
    her to pause before answering a question, it disrupted [the]
    proceedings in any way.” The court concluded that what the jury
    saw and heard was not “particularly emotionally charged” given
    the facts of the case.
    “Victim impact evidence is admissible during the penalty
    phase of a capital trial. [Citation.] Section 190.3, factor (a)
    permits the prosecution to establish aggravation by offering
    evidence of the circumstances of the crime, including the impact
    of the crime on surviving victims and on a victim’s family.”
    (People v. Peoples, supra, 62 Cal.4th at pp. 752–753.) “ ‘[T]he
    trial court is vested with considerable discretion in ruling on
    mistrial motions.’ ” (People v. Hines, 
    supra,
     15 Cal.4th at
    p. 1038.)
    We see no basis to conclude that the trial court abused its
    discretion. Y.M.’s testimony spanned less than one day,
    comprising around 15 transcript pages, and it concerned the
    victims and the impact of their deaths on her. We have routinely
    permitted the admission of similar evidence. (See, e.g., People
    v. Brady (2010) 
    50 Cal.4th 547
    , 574–579 [testimony about
    victim’s character, immediate reaction to victim’s death, and
    impact of victim’s death and videotape depicting victim]; People
    v. Peoples, supra, 62 Cal.4th at p. 753 [photographs of victim].)
    We have also stated that it is “a normal human response to the
    loss of a child” for a mother to cry on the stand, and that
    circumstance “does not render that testimony inflammatory.”
    (People v. Verdugo (2010) 
    50 Cal.4th 263
    , 298.) Even though
    97
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Juarez argues that we have unreasonably expanded the holding
    in Payne v. Tennessee (1991) 
    501 U.S. 808
     (Payne) to allow such
    testimony, he presents “no persuasive reason for us to overrule
    our own decisions regarding victim-impact evidence.” (People v.
    Weaver (2012) 
    53 Cal.4th 1056
    , 1086.) The trial court gave a
    reasoned ruling that Y.M.’s testimony did not invite an
    irrational response from the jury, and we conclude that her
    testimony did not render the trial fundamentally unfair.
    D. Execution-impact Evidence
    The trial court ruled that Juarez could not introduce
    testimony about the anticipated impact of his execution on his
    family unless it illuminated some positive quality in his
    background. Over his objection, the court accordingly instructed
    the jury: “You may not consider sympathy for the defendant’s
    family respecting the possibility of his execution except as it may
    illuminate some positive quality of the defendant’s background
    or character.”     Juarez contends this rendered his trial
    fundamentally unfair and violated his constitutional rights to
    present a defense, due process, equal protection, and a reliable
    penalty determination. He does not argue that the court
    improperly excluded specific testimony; rather, he argues that
    the impact of an execution is a circumstance of the crime and
    asks us to reexamine our contrary position.
    We have held that “[t]he impact of a defendant’s execution
    on his or her family may not be considered by the jury in
    mitigation.” (People v. Bennett (2009) 
    45 Cal.4th 577
    , 601;
    accord, People v. Williams (2013) 
    56 Cal.4th 165
    , 197–198.)
    None of the reasons offered by Juarez persuades us to revisit our
    precedent. First, he argues that the Eighth Amendment does
    not permit excluding evidence that might have mitigating value.
    98
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    “But nothing in that constitutional rule ‘limits the traditional
    authority of a court to exclude, as irrelevant, evidence not
    bearing on the defendant’s character, prior record, or the
    circumstances of his offense.’ ” (People v. Wall, supra, 3 Cal.5th
    at p. 1071; see People v. Gonzales (2012) 
    54 Cal.4th 1234
    , 1286–
    1287.) Second, he argues that our position conflicts with Payne,
    
    supra,
     
    501 U.S. 808
    , but it does not. (Cf. People v. Bennett, at
    p. 602 [Payne made clear that “a defendant must be allowed to
    introduce     mitigating    evidence    ‘concerning    his    own
    circumstances,’ ” but “execution-impact evidence is irrelevant
    under section 190.3 because it does not concern a defendant’s
    own circumstances”].) Finally, he observes that some courts
    have admitted execution-impact evidence, but none of the cases
    he cites are binding on this court.
    E. Prosecutorial Misconduct
    Juarez contends that the prosecutor engaged in repeated
    misconduct that impermissibly skewed his case toward death.
    He refers specifically to the prosecutor’s conduct concerning the
    jail visitation logs, Dr. Dougherty, and Orozco. Even though we
    have found and assumed misconduct, we conclude that for the
    reasons discussed, the misconduct, considered singly or
    cumulatively, “did not cause reversible prejudice” or amount to
    “a ‘pattern’ of misconduct so ‘egregious’ that it infected the trial
    with fundamental unfairness.” (People v. Shazier (2014)
    
    60 Cal.4th 109
    , 150, 151; see also People v. Mendoza (2007)
    
    42 Cal.4th 686
    , 705, 706, 709.)
    VI. OTHER ISSUES
    A. International Law
    Juarez contends that he was deprived of a fair trial and a
    reliable penalty in violation of customary international law as
    99
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    informed by the Universal Declaration of Human Rights, the
    International Covenant on Civil and Political Rights, the
    American Declaration of the Rights and Duties of Man, and the
    International Convention Against All Forms of Racial
    Discrimination. But we have held that “ ‘[i]nternational law
    does not prohibit a sentence of death when, as here, it was
    rendered in accordance with state and federal constitutional and
    statutory requirements.’ ”     (People v. Sattiewhite (2014)
    
    59 Cal.4th 446
    , 489; see also People v. Hillhouse (2002)
    
    27 Cal.4th 469
    , 511.)
    In addition, he contends that because racial
    discrimination permeates the death penalty, capital
    punishment itself violates international law and norms. He
    relies on statistical studies that purport to show racial
    disparities in the charging, sentencing, and imposition of the
    death penalty, particularly with respect to African-American
    defendants. We have rejected similar arguments and do so
    again here. (See, e.g., People v. Hajek and Vo, supra, 58 Cal.4th
    at p. 1253; People v. Martinez (2003) 
    31 Cal.4th 673
    , 703; People
    v. Jenkins (2000) 
    22 Cal.4th 900
    , 1055.)
    B. Challenges to the Death Penalty
    Juarez raises a number of challenges to the
    constitutionality of California’s death penalty statute that we
    have repeatedly rejected. Juarez provides no persuasive reason
    to revisit the following precedent:
    The death penalty statute as construed by this court does
    not fail to perform the narrowing function required by the
    Eighth Amendment. (People v. Schmeck (2005) 
    37 Cal.4th 240
    ,
    304.) Disputing this, Juarez argues in his reply brief that we
    have misinterpreted Pully v. Harris (1984) 
    465 U.S. 37
     and
    100
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    Tuilaepa v. California (1994) 
    512 U.S. 967
     in so holding. His
    argument does not persuade us to revisit our conclusion.
    Juarez claims that the failure to require the jury
    unanimously find true the aggravating factors relied on violates
    the federal Constitution. “ ‘Nothing in the federal Constitution
    requires the penalty phase jury to make written findings of the
    factors it finds in aggravation and mitigation[] [or] agree
    unanimously that a particular aggravating circumstance
    exists.’ ” (People v. Williams (2013) 
    58 Cal.4th 197
    , 295.) Nor is
    the death penalty statute unconstitutional for not requiring
    “findings beyond a reasonable doubt that an aggravating
    circumstance (other than Pen. Code, § 190.3, factor (b) or (c)
    evidence) has been proved, that the aggravating factors
    outweighed the mitigating factors, or that death is the
    appropriate sentence.”            (People v. Rangel (2016)
    
    62 Cal.4th 1192
    , 1235.) The high court’s recent decisions
    interpreting the Sixth Amendment’s jury trial guarantee do not
    alter our conclusions. (See Rangel, at p. 1235; People v. Lee
    (2011) 
    51 Cal.4th 620
    , 651–652; see also McKinney v. Arizona
    (2020) __ U.S. __, __ [
    140 S.Ct. 702
    , 708] [“Ring [v. Arizona
    (2002) 
    536 U.S. 584
    ] and Hurst [v. Florida (2016) __ U.S. __
    [
    136 S.Ct. 616
    ]] did not require jury weighing of aggravating
    and mitigating circumstances”].)
    “ ‘ “ ‘The sentencing factor of “circumstances of the crime”
    (§ 190.3, factor (a)) is not unconstitutionally vague and does not
    result in the arbitrary and capricious imposition of the death
    penalty.’ ” ’ ” (People v. Powell, supra, 6 Cal.5th at p. 193.)
    “ ‘The jury may properly consider evidence of unadjudicated
    criminal activity under section 190.3, factor (b) [citation], [and]
    jury unanimity regarding such conduct is not required
    [citation].’ ” (Ibid.) The trial court does not violate a defendant’s
    101
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    constitutional rights by failing to instruct the jury it must
    unanimously agree the defendant committed a prior crime
    under section 190.3, factor (c). (People v. O’Malley, supra,
    62 Cal.4th at p. 1014.)
    The trial court’s instructions need not “delete inapplicable
    sentencing factors, delineate between aggravating and
    mitigating circumstances, or specify a burden of proof either as
    to aggravation (except for other crimes evidence) or the penalty
    decision.” (People v. Schmeck, supra, 37 Cal.4th at p. 305.) “Nor
    are potentially mitigating factors unconstitutionally limited by
    the adjectives ‘extreme’ and ‘substantial’. . . .” (Ibid.) The
    sentencing factors are not vague and ill-defined. (Ibid.)
    The absence of written findings, intercase proportionality
    review, and disparate sentence review does not render the
    statute unconstitutional.        (People v. Pearson (2013)
    
    56 Cal.4th 393
    , 478; People v. Bryant, Smith and Wheeler,
    supra, 60 Cal.4th at p. 469; Ervine, 
    supra,
     47 Cal.4th at p. 811.)
    Imposition of the death penalty does not violate the Eighth
    Amendment’s prohibition against cruel and unusual
    punishment. (People v. Adams (2014) 
    60 Cal.4th 541
    , 581–582.)
    Finally, these asserted flaws, considered together, do not
    render the statute unconstitutional. (See People v. Pearson,
    supra, 56 Cal.4th at p. 479.)
    C. Cumulative Prejudice
    Juarez contends that the combined errors require reversal
    of his convictions and sentence. He additionally contends that
    to the extent errors at the guilt phase do not require reversal of
    his convictions, they nevertheless require reversal of his
    sentence.
    102
    PEOPLE v. SUAREZ
    Opinion of the Court by Liu, J.
    We have assumed error but found no prejudice at the
    preliminary hearing by the use of the unsworn, uncertified
    interpreter, the use of Juarez’s interpreter to interpret Y.M.’s
    outburst, and Juarez’s absence when his interpreter did so. We
    have declined to decide whether sufficient evidence supported
    the theory of felony murder for the murders of J.M. and A.M.,
    and while we have found sufficient evidence supported the
    theory of felony murder for the murders of José and Juan, we
    have assumed that even if there was no sufficient evidence, we
    still would uphold each of the first degree murder verdicts. We
    have additionally assumed or found error but no prejudice at
    trial regarding the difficulties that made it hard to hear the
    court proceedings, the accuracy of interpreters, the failure to
    timely advise Juarez of his right to have his consulate notified,
    the trial court’s denial of his motions to suppress evidence
    obtained during Detective Summers’s entry into the trailer and
    Juarez’s statements made during the walk-through, Deputy
    Walker’s testimony about Y.M.’s gesture, Orozco’s testimony
    about Juarez’s talk of “being with a girl,” and the prosecutor’s
    use of the jail visitation logs and contact with CMFG.
    Considering these actual or assumed errors altogether, we
    conclude that their cumulative effect does not warrant reversal
    of his convictions or sentence. (See People v. Page (2008)
    
    44 Cal.4th 1
    , 54; People v. Panah, 
    supra,

    PEOPLE v. SUAREZ
    S105876
    Concurring Opinion by Justice Liu
    Today’s opinion recognizes that while “ ‘the State has a
    strong interest in having jurors who are able to apply capital
    punishment within the framework state law prescribes,’ ” a
    criminal defendant “ ‘has the right to an impartial jury drawn
    from a venire that has not been tilted in favor of capital
    punishment by selective prosecutorial challenges for cause.’ ”
    (People v. McKinzie (2012) 
    54 Cal.4th 1302
    , 1328.)            “A
    prospective juror is properly excluded if he or she is unable to
    conscientiously consider all of the sentencing alternatives,
    including the death penalty where appropriate.” (Ibid., internal
    quotation marks omitted.) Here we decline to reconsider our
    decisions upholding the death qualification process. (Maj. opn.,
    ante, at pp. 16–21.)
    It bears mention, however, that although the United
    States Supreme Court in Lockhart v. McCree (1986) 
    476 U.S. 162
    , 168–173, rejected arguments that the death qualification
    process leads to conviction-prone juries, “a range of studies have
    continued to emerge post-Lockhart that build on the research
    [submitted in Lockhart] showing that death-qualified jurors are
    quite different from non-death-qualified jurors.” (Levinson et
    al., Devaluing Death: An Empirical Study of Implicit Racial
    Bias on Jury-Eligible Citizens in Six Death Penalty States (2014)
    89 N.Y.U. L.Rev. 513, 569, fn. 247 (hereafter Levinson); see id.
    at pp. 543, 568–569 [critiquing Lockhart and citing studies
    finding that death-qualified jurors tend to be more conviction-
    PEOPLE v. SUAREZ
    Liu, J., concurring
    prone than ordinary jurors]; Rozelle, The Principled
    Executioner: Capital Juries’ Bias and the Benefits of True
    Bifurcation (2006) 
    38 Ariz. St. L.J. 769
    , 784–785 [study of 1,201
    capital jurors from over 350 trials found that death-qualified
    jurors have disproportionately punitive orientations, are more
    likely to hold racial stereotypes, and are more likely to be pro-
    prosecution and conviction-prone]; see also Butler, Death
    Qualification and Prejudice: The Effect of Implicit Racism,
    Sexism, and Homophobia on Capital Defendants’ Right to Due
    Process (2007) 
    25 Behav. Sci. & L. 857
    ; Butler & Wasserman,
    The Role of Death Qualification in Venirepersons’ Attitudes
    Toward the Insanity Defense (2006) 36 J. Applied Soc. Psych.
    1744.)
    In a multifaceted study of 445 jury-eligible citizens in six
    death penalty states, including California, researchers found
    that “the process of death qualification results in capital jurors
    with significantly stronger implicit racial biases . . . and explicit
    racial biases than jury-eligible citizens generally.” (Levinson,
    supra, 89 N.Y.U. L.Rev. at p. 569; see id. at pp. 559–560.) The
    study further found that “death-qualified juries possess stronger
    implicit biases because the process results in the
    disproportionate elimination of non-White jurors.” (Ibid., italics
    omitted; see id. at pp. 559.)
    This latter finding coheres with a substantial body of
    evidence that Black jurors are significantly more likely than
    Whites to be excused for cause. (Frampton, For Cause:
    Rethinking Racial Exclusion and the American Jury (2020) 118
    Mich. L.Rev. 785, 792–805 (hereafter Frampton); Cover, The
    Eighth Amendment’s Lost Jurors: Death Qualification and
    Evolving Standards of Decency (2016) 
    92 Ind. L.J. 113
    , 136–138
    (hereafter Cover) [examining 1,445 venire members in 11

    capital trials in Louisiana between 2009 and 2013]; Eisenberg,

    South Carolina Capital Cases, 1997–2012 (2017) 9 Ne. U. L.Rev.

    Walks Like Systematic Exclusion and Quacks Like Systematic
    Exclusion: Follow-Up on Removal of Women and African-
    Americans in Jury Selection in South Carolina Capital Cases,
    1997–2014 (2017) 68 S.C. L.Rev. 373, 387–388.) In many cases,
    the magnitude of racial disparities is greater among jurors
    excused for cause than among jurors excused through
    peremptory strikes. (See Frampton, at pp. 800–801; Removal,
    at pp. 335–339, 342–344.) And this phenomenon is not limited
    to capital cases. (See Frampton, at pp. 794–795 [study of 316
    Louisiana criminal trials with 14,616 prospective jurors, 62
    percent White and 33 percent Black, showed that jurors
    challenged by prosecutors for cause were 59 percent Black and
    34 percent White, while jurors targeted by prosecutors for
    peremptory strikes were 54 percent Black and 41 percent
    White]; 
    id.
     at pp. 796–798 [study of 83 Mississippi criminal
    trials with 4,717 prospective jurors, 60 percent White and 34
    percent Black, showed that jurors challenged by prosecutors for
    cause were 80 percent Black and 21 percent White, while jurors
    targeted by prosecutors for peremptory strikes were 68 percent
    Black and 32 percent White].)
    Thus, although much attention has appropriately been
    paid to the inefficacy of Batson v. Kentucky (1986) 
    476 U.S. 79
    in combating racial discrimination in peremptory strikes, there
    is significant evidence that removal of jurors for cause is an
    equally if not more significant contributor to the exclusion of
    Black jurors, which may result in juries with higher levels of
    implicit bias.
    3
    PEOPLE v. SUAREZ
    Liu, J., concurring
    Here, defendant raises these concerns but does not tie
    them to the record in this case. It would be difficult to do so. As
    one observer explains, “This data is buried in attorneys’ notes
    and in transcripts of the jury voir dire proceedings in individual
    capital cases. Strike data are enormously labor intensive to
    obtain and to aggregate in a meaningful way.” (Cover, supra, 92
    Ind. L.J. at p. 130.) Thus, a starting point for addressing this
    issue may be to require public reporting of the demographic
    composition of jury venires and of the prospective jurors who are
    excused for cause. (See, e.g., id. at pp. 148–149 [proposing
    legislation or a rule of court to require reporting of such data].)
    Transparency is an important first step to understanding the
    extent to which racial dynamics affect jury selection.
    Several efforts are presently underway in California to
    make juries more inclusive and representative of our
    communities. These include a bill to reform the legal framework
    for rooting out discrimination in the exercise of peremptory
    strikes (Assem. Bill No. 3070 (2019–2020 Reg. Sess.) as
    amended July 8, 2020) and a bill to expand the jury pool to
    include all people who have filed a state tax return (Sen. Bill No.
    592 (2019–2020 Reg. Sess.)). Other proposals may soon be in
    the works. (See Cal. Courts Newsroom, California Supreme
    Court Names Jury Selection Work Group (July 6, 2020).) If the
    goal of these efforts is to better ensure that juries reflect a cross-
    section of our communities, then the topics worthy of attention
    4
    PEOPLE v. SUAREZ
    Liu, J., concurring
    may include whether current standards and processes for
    excusal of prospective jurors for cause contribute to racial
    disparities in jury selection and to implicit biases in the
    resulting petit juries.
