    A jury in San Bernardino County convicted defendant
    Louis Mitchell, Jr., of three counts of first degree murder of
    Mario Lopez, Patrick Mawikere, and Susano Torres (Pen. Code,
    § 187, subd. (a); all undesignated references are to this code),
    and three counts of first degree attempted murder of Juan
    Bizzotto, Jerry Payan, and Armando Torres (§§ 664, 187,
    subd. (a)), arising from two shootings committed by Mitchell on
    August 8, 2005. The jury found true special circumstance
    allegations that Mitchell committed multiple murders and the
    enhancements that in each offense Mitchell personally and
    intentionally discharged a firearm. (§§ 190.2, subd. (a)(3),
    12022.53, subd. (d).) The jury returned a verdict of death. The
    trial court then sentenced Mitchell to death for the three counts

    sentence of 150 years to life in prison for the three counts of
    conviction of first degree attempted murder and the firearm
    enhancements. This appeal is automatic. (Cal. Const., art. VI,
    § 11; § 1239, subd. (b).) We affirm the judgment in all respects.

    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    I.     FACTS
    A. Guilt Phase
    1. Prosecution Evidence
    (a) Mitchell and Small’s Visit to Car Dealership
    on August 8, 2005
    In August of 2005, Mitchell and Dorene Small were living
    together in an apartment in Rialto, along with Small’s five
    children and three of Mitchell’s children. Small had recently
    been in a car accident and received a settlement from her
    insurance company. She intended to use the settlement
    proceeds to buy another car.
    On August 8, 2005, after Small picked up the settlement
    check from her insurance company, she and Mitchell went to
    California Auto Specialist (CAS), a used car dealership in
    Colton, to shop for a replacement vehicle. They arrived at CAS
    between 10:00 and 10:30 in the morning in Small’s white
    Chevrolet Lumina. Small testified that although she owned the
    Lumina, it was often driven and used by Mitchell.
    At first, they were helped by CAS salesman Juan Bizzotto.
    Because Bizzotto could not speak English well, he referred them
    to his colleague, Mario Lopez. Ultimately, Lopez helped Small
    complete paperwork to purchase a used Dodge Durango truck.
    According to the testimony of another CAS salesman Jerry
    Payan, it appeared that Mitchell tried to dissuade Small from
    buying the Durango because he preferred a larger truck. But
    Small did not like the bigger truck, and her poor credit status
    prevented her from qualifying for the more expensive truck that
    Mitchell preferred.
    Mitchell left CAS, leaving Small to finalize the car
    purchase with Lopez on her own. There was conflicting
    2
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    testimony as to Mitchell’s demeanor when he left Small. Payan
    recalled that Mitchell was angry with her over her choice.
    Bizzotto, on the other hand, remembered Mitchell acting “fine”
    during the deal, despite his disagreement with Small’s decision.
    Small then told Lopez that she needed to cash a check at
    a bank in order to make the downpayment. Lopez agreed to
    allow Small to drive the Durango to the bank, and Bizzotto
    followed Small in a separate car. On the way back to the
    dealership, the Durango broke down and could not be restarted.
    They left the Durango on the side of the road for repairs, and
    Bizzotto drove Small back to the dealership.
    Small testified that she was not upset about the
    breakdown of the Durango, and Bizzotto confirmed in his
    testimony that Small had reacted calmly. According to Bizzotto,
    Small went ahead with the purchase of the Durango, even
    though she had the right to back out of the deal. Small chose to
    take a loaner car and allow the dealership to fix the Durango.
    While still at the dealership, Small called home to tell her son
    Kenrod Bell that she had bought a car but was not coming home
    with it because it broke down.
    When Small arrived home, Mitchell was not there, and she
    did not see her Chevy Lumina. Small noticed that Mitchell had
    left his cell phone, which was unusual for him. Small then left
    for work, arriving there around 2:30 p.m. But she left shortly
    thereafter because she was not feeling well, and she returned
    home around 4:00 p.m.
    Around 2:00 p.m., Mitchell called Christina Eyre, who at
    the time of trial was Mitchell’s girlfriend. Eyre testified that she
    and Mitchell had been in a relationship for about two years,
    including the time that Mitchell was together with Small. Their
    3
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    conversation lasted less than five minutes. Mitchell mentioned
    to Eyre that he and Small had been “screwed over” in a car deal;
    according to Eyre, Mitchell did not say he was mad, but noted
    that Small had insisted upon buying the defective Durango.
    Eyre further stated that she heard Romen Williams, also known
    as “Chrome,” and Small’s son Bell in the background.
    (b) Shooting at the Car Dealership
    Between 2:15 p.m. and 2:30 p.m. on August 8, 2005,
    Payan, Lopez, and Patrick Mawikere were gathered at Payan’s
    desk facing the window overlooking the car lot. They saw
    Mitchell return to the dealership driving the same white
    Lumina in which he and Small had arrived earlier that day.
    Bizzotto, who was on his desk phone talking with his wife at the
    time, also noticed Mitchell. Bizzotto saw that Mitchell was not
    alone; he was accompanied in the Lumina by two other people.
    Bizzotto described the two as African American men between 25
    and 35 years of age; they remained in the car as Mitchell entered
    the dealership.
    There were no customers in the dealership at the time.
    Payan and Bizzotto both testified that they saw Lopez meet
    Mitchell at the entrance of the dealership office. Mitchell
    repeatedly asked Lopez where Small was. Lopez replied that
    Small had left to go to work. Both Payan and Mawikere stood
    up, intending to assist Lopez. Although Payan was not alarmed
    by Mitchell’s behavior at this time, Bizzotto testified that
    Mitchell was excited and angry, in contrast to his behavior
    earlier that day.
    Payan then saw Mitchell pull a gun out of his pants pocket
    and shoot Lopez. Payan testified that Mitchell was looking at
    Payan while he shot Lopez. When Payan heard a second
    4
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    gunshot, he ran toward a window looking to escape. Because
    Mitchell was standing in front of the only exit, Payan decided to
    escape by jumping through the closed window. Before he
    crashed through the window, Payan heard two or three more
    gunshots and was shot in the right arm. Payan landed between
    two large cars parked outside the office and crouched between
    them. Mitchell pointed his gun outside the window and shot at
    him. Payan heard one or two more gunshots, but he was not hit.
    As he continued to crouch between the two cars, Payan heard
    another series of gunshots coming from inside the dealership.
    He also noticed that Mitchell’s white Lumina was in front of
    him, with a man sitting in the front seat. Payan made eye
    contact with him, and the man exited the Lumina. According to
    Payan, the man was a tall, thin African American man, perhaps
    18 or 19 years old. Payan saw that this man had his hand down
    by his side, and it looked like he had a gun. Payan then ran
    across the dealership lot and across the street, seeking help.
    Payan ultimately caught the attention of an ambulance and was
    given medical assistance on the street before being transported
    to a hospital.
    Bizzotto testified that he saw Mitchell push Lopez back
    from the front door of the dealership as Lopez was attempting
    to escort him outside, pull out a gun, and shoot Lopez in the
    abdomen. Bizzotto then saw Payan jump through a window
    while Mitchell shot at Payan. When Mawikere tried to
    intervene, Bizzotto saw Mitchell point his gun at Mawikere, and
    Mawikere asked Mitchell not to shoot him. Mitchell then shot
    Mawikere in the head and turned toward Bizzotto. Bizzotto
    attempted to hide underneath his desk, and Mitchell started
    shooting at him. Bizzotto was shot in the right arm and the
    right thigh. Mitchell fired another seven times at Bizzotto,
    5
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    causing Bizzotto to suffer shrapnel wounds to his left leg. After
    he heard two additional shots, the sound of the door opening,
    and a car being driven away, Bizzotto emerged from underneath
    his desk. He saw that Lopez was injured and told him to remain
    calm.    He saw that Mawikere had been shot and was
    unresponsive. Bizzotto instructed his wife, who was still on the
    phone, to call 911. Bizzotto also called 911 himself.
    John Vasquez was driving by the dealership around 2:30
    p.m., when he saw Bizzotto come out of the dealership with blood
    running down his arm.          He testified that Bizzotto was
    staggering and being assisted by another man who was holding
    his arm up. Vasquez noticed a broken window and thought that
    Bizzotto had fallen through it, so he stopped to offer help.
    Bizzotto told Vasquez that he had been shot by two black men
    and that he feared for his life.
    Responding to the 911 calls, officers from the Colton Police
    Department arrived at CAS at approximately 2:45 p.m. They
    found that a window in front of the dealership office had been
    smashed, and there was a trail of blood outside the window
    leading south toward the street. Officers encountered Bizzotto
    outside the dealership and saw that he had been shot in the arm.
    Bizzotto told them that the person responsible was a black man
    who had been at the dealership earlier that day to buy a black
    Durango. Inside the office of the dealership, officers found
    Lopez lying on the floor on his back, near the front door. Lopez
    was conscious and in pain from two gunshot wounds but able to
    relate that a lone black man, who had arrived in a white 1997
    Chevy Lumina, had shot him. The officers then found Mawikere
    behind a desk, dead and facedown with a gunshot wound to the
    6
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    head. Lopez died later that night at the hospital as a result of
    three gunshot wounds.
    The police interviewed Payan and Bizzotto at the hospital
    where they were being treated for their injuries. Payan was
    shown photo displays of two suspects. At first, Payan was
    unable to cooperate because he was under the influence of
    morphine.      Thereafter, Payan identified a photograph of
    Mitchell as the shooter. Bizzotto was physically unable to talk
    to the officer who visited him at the hospital. After his discharge
    from the hospital, Bizzotto was shown a display of six
    photographs and identified Mitchell’s photograph as the person
    who shot him.
    (c) Shooting at the Yellows Apartment Complex
    The Yellows was the colloquial name given to an
    apartment complex in San Bernardino. On August 8, 2005,
    around 3:00 p.m, Armando Torres was at the complex visiting
    his mother and his brother Susano Torres. Mitchell had
    previously lived at the complex and still visited it frequently.
    Armando and Susano knew Mitchell from around the complex
    and had not had any problems with him.
    On his way to a friend’s apartment, Armando saw Susano
    speaking to Rita Ochoa through the window of her apartment.
    Armando told Susano that their mother was looking for him.
    Armando then went to his friend’s apartment, where he smoked
    methamphetamine.
    As Armando came out of his friend’s apartment, Mitchell
    walked towards him and said, “Hey devil, let me talk to you,”
    and repeatedly told Armando to “come here.” Armando had an
    unusual tattoo of horns on his head. Armando testified that
    Mitchell appeared to be upset. Armando asked what Mitchell
    7
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    wanted, and Mitchell demanded that Armando come to him.
    Armando refused and Mitchell pulled out a gun and said, “You
    fucked up.” Mitchell shot at Armando at least three times,
    hitting him once in the leg as a woman managed to pull him
    inside her apartment and call 911. Armando stated that he
    heard more shots fired about 30 seconds later.
    Susano was joined by his friend Phillip Mancha, and they
    were talking to Ochoa outside her window when they heard
    shots. Mancha climbed through Ochoa’s window, and he and
    Ochoa got down on the ground. Susano went to check what was
    happening and encountered Mitchell.           According to the
    testimony of another resident of the Yellows, Valerie
    Hernandez, Mitchell shot Susano. He was with Romen
    Williams, and one of them said something to the effect of “[f]uck
    that. That’s what they get.” Hernandez could not see Mitchell’s
    face because it was obscured by the leaves of a tree in her line of
    sight, but she saw his body and a gun in his hand when the shots
    were fired. Then after the shots were fired, she saw Mitchell
    pull down the gun to his side and walk away between the
    apartments toward the parking area. Mancha testified that he
    heard Susano getting hit and yelling for help. Ochoa testified
    that she looked outside and saw Susano on the ground bleeding
    from the nose. The bullet passed through both of Susano’s
    lungs, and he died shortly thereafter from internal bleeding.
    Neither Ochoa nor Mancha identified Susano’s shooter.
    Just before 3:00 p.m., Rosalba Villaneda, Armando’s
    sister-in-law and a resident of the Yellows, heard several
    gunshots being fired. She testified that about five minutes later,
    Mitchell walked by them with a gun in his right hand,
    unaccompanied. Although Villaneda did not know him by name,
    8
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    she was familiar with Mitchell. Mitchell then entered a car on
    the passenger side and left the area.
    Shortly thereafter, San Bernardino police officers arrived
    at the Yellows to respond to the incident. Officer James Voss
    saw a group of people by Torres, who was lying in a dirt area
    with no pulse. Voss called for medical assistance. A resident of
    the Yellows then directed Voss to her apartment, where he
    found Armando on the floor.
    (d) Mitchell’s Arrest
    On the next day, August 9, 2005, Mitchell went to the Del
    Mar apartment complex in San Bernardino. He was at Tracy
    Ruff’s apartment, where he and another person were smoking
    marijuana and cigarettes. Suddenly, Mitchell pulled out his gun
    and fired it into the air six or seven times. Then Mitchell walked
    out in front of the apartment complex, waving his gun in the air.
    A nearby resident, Patricia Conger, saw Mitchell pointing his
    gun at other cars, people, and houses. Around the same time,
    another nearby resident, James Morrison, was outside his house
    working on a car and heard several gunshots. He then saw
    Mitchell waving a gun, so Morrison ran into his house.
    Ruff followed Mitchell to the street and saw Mitchell wave
    his gun in the air and say, “I killed the devil.” Ruff told Mitchell
    that the police were going to come and asked Mitchell to give
    him the gun. Ruff returned to the apartments and hid the gun
    in the tire well of a van in the rear parking structure.
    Officer Thomas Adams arrived on the scene, and Mitchell
    immediately started yelling at him. Officer Adams testified that
    he made numerous commands that Mitchell ignored. Instead of
    complying, Mitchell kept approaching the officer and said, “My
    gun is bigger than yours. Fuck it. I’ll just take your gun.”
    9
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Officer Adams then shot Mitchell in the leg to stop him from
    advancing.
    Officer Kevin Jeffery testified that Mitchell was agitated
    when officers were handcuffing him and in the ambulance on
    the way to the hospital. During this time, Mitchell told Officer
    Joshua Cogswell that if he was going to die, the officer was going
    to go with him. He also told Officer Jeffery, “God would not
    judge him for killing the devil.”
    (e) Forensic Evidence
    Criminalist Heather Harlacker located one fired cartridge
    case outside the CAS office building and 10 more fired cartridge
    cases and bullet fragments inside the building. According to
    Harlacker’s expert testimony, all 11 cartridge casings were from
    the same nine-millimeter caliber gun. Seven cartridge casings,
    all nine-millimeter casings of the same brand, and nine bullet
    fragments were collected at the Yellows. At the Del Mar
    complex crime scene, a forensic technician recovered a nine-
    millimeter gun containing an empty magazine concealed in the
    wheel well of a van, with Mitchell’s DNA on it. Criminalist Kerri
    Heward concluded that six of the seven cartridge casings had
    definitely been fired from the same nine-millimeter gun
    retrieved, and the other cartridge probably was.             The
    technician also recovered a second empty nine-millimeter
    magazine inside the pocket of Mitchell’s pants. Furthermore,
    Heward opined that the casings recovered from the car
    dealership, the Yellows, and the Del Mar complex were all fired
    from Mitchell’s gun.
    2. Defense Evidence
    The defense case focused on inconsistencies in the
    witness’s testimony and the lack of scientific evidence. Defense
    10
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    counsel argued that Payan’s account of Lopez’s death conflicted
    with the medical examiner’s findings. Counsel challenged the
    credibility of Armando’s testimony on account of the fact that he
    was under the influence of methamphetamine and his brother
    was killed, and additionally pointed out inconsistencies in his
    recitation of the facts. Counsel also challenged Hernandez’s
    recitation of the facts as inconsistent. Finally, defense counsel
    underscored that the bullets recovered from the victims could
    not be matched to the casings at the crime scenes and to
    Mitchell’s gun.
    B. Penalty Phase
    1. Prosecution Evidence in Aggravation
    (a) Criminal Activity Involving Force or Violence
    (1) July 10, 1998 Carjacking
    The prosecution presented evidence that Mitchell was
    involved in a carjacking on July 10, 1998. Around 5:30 p.m. on
    that day, Rebecca Davis and Lupe Chavez were parked at a store
    in San Bernardino, talking to each other. Chavez was in the
    driver’s seat, Davis was in the passenger seat, and Davis’s infant
    daughter was sitting in between them. Davis noticed two black
    males talking to each other. One of them approached the
    driver’s side, and the other, Mitchell, approached the
    passenger’s side of the car. The man on the driver’s side was
    wearing brass knuckles and told Chavez to get out of the car.
    When she refused, he pulled her out of the car and she fell to the
    ground. Mitchell told Davis to get out and get her baby out of
    the car, and she complied. The men then drove away in the car.
    (2) August 9, 2005 Firing of Gun
    The prosecution then presented evidence about the events
    at the Del Mar complex on August 9, 2005. Around 3:00 p.m.,
    11
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Mitchell was in the middle of 19th Street with a gun. Brenda
    Wierenga and David Roark were in a car on the street at the
    time. Wieranga saw Mitchell pointing a gun at her and ducked
    under the steering wheel. Mitchell fired the empty gun five to
    six times at the car’s passenger side where Roark was seated.
    Mitchell made a number of threatening and racially charged
    statements at Wieranga and Roark, such as: “Hey, anybody
    want to come out here and fight me? We can get down right
    now”; “All you whites and Mexicans stay inside”; and “Where is
    all my n–––––?” As Wieranga drove the car away, Mitchell said,
    “See y’all don’t want none.” Mitchell then pointed his gun at the
    sky, took out the clip, and pointed it at his head and said, “See,
    I’ll even shoot myself.” He also said to himself, “Go back inside.
    You all need to go back inside. The devil is talking to me.”
    Armando DeSantiago, who worked for Federal Express,
    was delivering a package on 19th Street when he heard
    gunshots. He testified he saw Mitchell in the middle of the
    street pointing his gun indiscriminately and yelling, “I’m the
    devil. I’m going to shoot everybody. Just come out wherever you
    are.” Mitchell saw DeSantiago, pointed the gun at him, said,
    “I’m going to kill you” and to “get out of there”; Mitchell then
    pulled the trigger three times from a short distance away. In
    fear, DeSantiago hid behind his truck.
    Mitchell then went back inside the apartment complex
    and came back out. He was followed by Ruff telling him to calm
    down. Mitchell and Ruff struggled over the gun and finally
    Mitchell gave it to him. When the officer arrived, Mitchell
    walked toward the officer, pantomiming that he had a gun in his
    hand and was firing it. Mitchell said to the officer, “Come on,
    you’re a cop. You’re supposed to kill me.” Mitchell was arrested
    12
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    soon thereafter, and he told an officer to remove his handcuffs
    and said he would “kick his ass.”
    (b) Victim Impact Evidence
    (1) Murder of Mario Lopez
    Rene Lopez, one of Mario Lopez’s four sons, testified about
    his father. Rene described Mario as a caring, happy man. He
    described Mario as “the best mechanic in the world. The best
    father. The best grandfather.” Mario doted on his grandson and
    loved spending the holidays with Rene’s family. He also loved
    spending time with his wife Cecelia.
    Rene traveled to the hospital when he heard Mario was
    shot and stayed with him until he died. Since his father’s death,
    Rene said there are “times I lose myself” when he goes through
    bouts of depression. Rene also misses the relationship his father
    had with his son.
    Cecelia Lopez had been Mario’s partner for nine years.
    She described Mario as a family man, always concerned about
    his children and grandchildren. She described him as a
    gentleman and very hardworking.
    Since his death, Cecelia had to sell their house, move in
    with her daughter, and give up her two dogs. Cecelia said that
    what she missed most about Mario was his presence, his caring,
    and how he looked after her. For example, he used to remind
    her to take her medication. Furthermore, she testified that her
    medical problems have gotten worse since Mario was murdered
    due to high blood pressure and anxiety.
    Payan had known Mario Lopez for over five years. He
    described Mario as always concerned about everybody else. He
    13
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    missed Mario’s advice and encouragement, like when Mario
    would tell him not to worry about the small things.
    (2) Murder of Patrick Mawikere
    Several witnesses testified about the impact of Patrick
    Mawikere’s murder on their lives. Patrick’s father, John
    Mawikere, testified about his son. Patrick had an apartment
    with his brother Sandy, but often visited his parents on his days
    off. John testified that Patrick loved working and was very
    generous with his money. Patrick had a lot of friends; more than
    1,600 people attended his funeral. Patrick loved to take his
    niece and nephew out. Patrick and his mother, Mary Mawikere,
    were very close; they spoke every day. Mary had to go to
    counseling to cope with Patrick’s death. Payan testified that he
    had known Patrick for two years, and they became friends. He
    said Patrick was raised very well by his parents, was hard
    working, and had set a number of goals for himself.
    (3) Attempted Murder of Jerry Payan
    Prior to being shot, Payan was a very active person. He
    testified that he has lost some function in his right arm and is
    still suffering from the injury to his knee. He testified that he
    was frustrated and angry because he could no longer do things
    like hug his wife, hold his children, and play sports with his son.
    Payan’s wife, Doris Payan, described the changes in their
    lifestyle since the shooting. Instead of spending days off taking
    their son to the amusement park and doing other activities, they
    spent that time going to therapy. She further testified that
    Jerry was no longer the calm person he once was; he used to be
    jovial and joke with people, but he became easily agitated. He
    was also uneasy at home; he did not feel safe and often worried
    that he would not be able to protect her if something happened.
    14
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    (4) Attempted Murder of Juan Bizzotto
    When Bizzotto was shot, he had one-year-old twins. He
    testified that the injury from his gunshot wound severely
    limited the use of his right hand and arm such that he could no
    longer lift his children or feed them with his right arm.
    Furthermore, Bizzotto’s mental and emotional health was
    adversely affected by the shooting. He testified that he had
    trouble going out in public. Moreover, he was no longer able to
    work.
    (5) Murder of Susano Torres and Attempted
    Murder of Armando Torres
    Rafaela Navarete testified about her sons, Susano and
    Armando Torres. She testified that Susano loved playing with
    her grandchildren and that he helped watch them. She said
    Susano was a happy child who loved to work with his hands; he
    liked to take things apart and put them back together. Navarete
    knew Mitchell, as he was friends with her children and would
    come by and ask for them. She testified that Mitchell even
    called her “mom.” She was angry at Mitchell and did not
    understand why he killed Susano. As a result of the stress, she
    had to go to the hospital. Navarete thereafter moved from the
    Yellows complex. Following Susano’s death, she went to the
    cemetery every day to visit him, where she cried and talked to
    him.
    Sergio Quintero, Susano and Armando’s older brother,
    also testified. At one point, Susano lived with Quintero in
    Redlands before Susano moved in with their mother. Quintero
    said Susano was his friend and they spent a lot of time hanging
    out together.
    15
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Beatriz Lopez, Susano’s older sister, recalled that Susano
    was a good child. Whenever she went to their mother’s house,
    Susano was often playing with the kids. She recalled that when
    she was cooking, Susano would come up from behind her, hug
    her, and say, “I love you, sis.” She said that she misses
    everything about Susano and that they had a great relationship.
    She also testified that this last Christmas, her mother did not
    want to be with the family and instead spent time alone in her
    room.
    Armando Torres testified that he missed Susano’s smile,
    how Susano used to treat him, and the time they spent hanging
    out together. He said Susano was a nice person and a good kid.
    Armando had not returned to the Yellows since the shootings
    because he did not want to remember it. Armando testified that
    when he thought about his brother, he used drugs to make his
    thoughts go away.            After the shootings, Armando’s
    methamphetamine use became worse; he testified that he kept
    “messing up,” resulting in further arrests. Armando testified
    that at the time of his testimony, he was in custody for criminal
    charges relating to an assault, possession of drugs, and
    possession of a firearm.
    2. Mitigation Evidence
    (a) Mitchell’s Family and Childhood
    Mitchell’s mother, Kathy Joiner, was 16 years old when
    she married Mitchell’s father, Louis Mitchell, Sr. Mitchell, the
    first of their three children together, was born in 1970.
    Mitchell’s father returned from service in the Marines in 1971.
    Mitchell’s parents had a tumultuous marriage and separated
    three times before their divorce in 1975.
    16
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Mitchell and his younger brother, Dante Mitchell, were
    ages six and five, respectively, when their father went to jail.
    Mitchell’s uncle, John Mitchell, and his wife took Mitchell and
    Dante in and cared for them. They stayed with John for about
    four and a half months until the state placed them in the foster
    system. John described Mitchell’s father as an “absentee dad,”
    even to this day. John said that Mitchell’s parents were both
    very young and inexperienced, and incapable of raising children.
    Joiner testified that she failed her son as a mother.
    Dante Mitchell testified that when he was eight and
    Mitchell was ten, they lived with a couple named Matty and Big
    Jim until they moved back in with their father. Things began
    to deteriorate from there, and at their father’s request, they
    went back into foster care. They were then returned to their
    mother in 1979 and, shortly thereafter, removed from her care
    when she was arrested for alleged child abuse and neglect. The
    last time Dante had seen Mitchell was on the morning of August
    9, 2005. Mitchell came to Dante’s house in Los Angeles just
    before Dante was leaving for work around 8:00 a.m. He told
    Dante that he looked like Mitchell’s children and that he loved
    him.
    Wendy Williams was Mitchell’s stepmother but had been
    separated from Mitchell’s father for about 22 years. She
    testified that Mitchell and Dante had lived with her and
    Mitchell, Sr., on two occasions for relatively short periods of time
    when they were younger. She further testified that Mitchell,
    Sr., had poor parenting skills and that he did not interact with
    any of his children. Williams last saw Mitchell when he was 17
    years old.
    17
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Lashona Blue, with whom Mitchell has three children,
    also testified. Their children were 11-year-old twins Hasan and
    Amena, and eight-year-old Mustafa. Blue and Mitchell met in
    1994 and lived together in Los Angeles for three to four years.
    She testified that Mitchell loved their children, was a good
    father, and never abused her in any way. Blue said she had
    some great times with Mitchell and their children, and that he
    was never vicious. She stated that her sons were having
    problems and acting out because of their father’s situation.
    Mitchell’s daughter Amena testified that she loved her
    father but knew he was in a lot of trouble. She promised she
    would stay in touch with him and send him letters.
    (b) Mitchell’s Criminal and Mental Health History
    Mitchell was convicted in August 1988 for unlawfully
    taking a motor vehicle and placed on felony probation. In
    December 1989, he was convicted of possession of cocaine for
    sale. He was arrested in March 1990 for possession of cocaine
    and convicted in August 1990. Mitchell was arrested in August
    1992, and ultimately convicted in November 1992 of possession
    of cocaine base for sale. His probation for the carjacking offense
    in 1988 was revoked, and he was sentenced to four years in
    prison. In December 1996, Mitchell was convicted of possession
    of marijuana for sale and granted probation. He was convicted
    of possession of PCP in July 2000, sentenced to two years in
    prison, and released in January 2002. Thereafter, he was
    arrested again for possession of cocaine base for sale, convicted
    in December 2002, and sentenced to prison for four years.
    Karen Hofmeister of the University of California, San
    Diego psychiatry department interviewed Mitchell in June 2004
    at the California Institute for Men, in advance of Mitchell being
    18
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    paroled in order to gather information for the Parole Outpatient
    Clinic. She wrote in her report that Mitchell appeared
    depressed.
    While still incarcerated, Mitchell came under the care of
    Dr. William Lawrence, who treated Mitchell for depression and
    prescribed a number of medications for Mitchell while he was in
    prison, including the antidepressant Wellbutrin. According to
    Dr. Lawrence’s notes, there did not appear to be any change in
    Mitchell’s mood or mental status from July 2004 to February
    2005, and his medication did not change. The last time he saw
    Mitchell was in March 2005; his mental status exam was,
    according to Dr. Lawrence, “in essence, normal.” He had a
    diagnosis of dysthymia, or persistent depressive disorder, and
    was on the same dose of Wellbutrin.
    Dr. Nuingyu Kim, a psychiatrist for the Department of
    Corrections and Rehabilitation, met with Mitchell on June 24,
    2005, and Mitchell told him that he had stopped taking
    Wellbutrin. Before the meeting, Dr. Kim read a brief summary
    of his social background. It stated that Mitchell had a long
    history of being institutionalized, abused as a child, and a long
    history of substance abuse, including PCP. Dr. Kim was
    concerned that Mitchell stopped taking his medication, but Dr.
    Kim could not force Mitchell to take it. As a result, they agreed
    that Mitchell would continue to see Dr. Kim once a month in
    case he needed medication, but then Mitchell did not show up
    for his next scheduled appointment.
    Parole Agent Steven Day supervised Mitchell for a short
    period of time and said Mitchell appeared compliant with his
    parole. He testified that during those three months or so,
    Mitchell never tested positive for any kind of narcotics. The last
    19
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    time he was tested was two to three days prior to his arrest for
    the three murders.
    (c) Mitchell’s PCP Use
    After Mitchell’s encounter with the police on August 9,
    2005, Dr. Jeff Grange treated Mitchell at the hospital for a
    gunshot wound and psychiatric symptoms. Mitchell arrived in
    an almost catatonic state and then later exhibited bizarre
    behavior. Based on this and the events with the paramedics and
    law enforcement, Mitchell was tested for drugs. A presumptive
    urine test was positive for PCP and marijuana. It was Dr.
    Grange’s opinion that Mitchell likely had PCP in his system and
    that he exhibited behavior consistent with being on PCP. An
    independent laboratory confirmed that Mitchell had PCP in his
    system.
    Felix D’Amico testified as a drug recognition expert. He
    said that symptoms of PCP appear almost immediately after
    smoking it and usually peak two to three hours later. He further
    noted that clinical symptoms continue for up to four to six hours
    and that behavioral manifestations continue for up to 11 hours.
    He noted that because PCP is stored in fatty cells and can be
    released by adrenaline, behavioral manifestations can reoccur
    even weeks later. Some of the behaviors he has observed in
    people under the influence of PCP include being agitated or
    excited, having hallucinations or delusions, and paranoia. Their
    vital signs (pulse, body temperature, blood pressure) are
    extremely high.       Other symptoms include abnormal eye
    movements, blank stare, and inability to verbalize. He testified
    that these symptoms tend to cycle, such that one moment the
    individual will be calm and another moment something might
    set them off. He noted that when PCP is used with marijuana,
    20
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    a user may experience greater impairment in terms of
    misperception of time, space, and distance, in addition to the
    possible symptoms from the PCP. Based on his review, D’Amico
    stated his opinion that Mitchell was under the influence of PCP
    on August 9, 2005.
    Dr. Alan Abrams examined Mitchell and testified as an
    expert on psychopharmacology. He also reviewed Mitchell’s
    childhood school records and concluded they were consistent
    with Mitchell growing up in a highly unstable, abusive, and
    neglectful home. Mitchell and his siblings were in and out of
    foster care and group homes because of their mother’s abuse and
    neglect and their father’s inability to care for them. As a child,
    Mitchell tested average to above average in intelligence, but his
    academic performance was poor.
    Review of Mitchell’s health records disclosed that Mitchell
    had a psychiatric diagnosis of dysthymia and was prescribed a
    variety of antidepressants including Remeron, Paxil, Prozac,
    and Wellbutrin. Dr. Abrams described dysthymic disorder as a
    type of depression that people experience when they have been
    unhappy their whole life, but not to the extremes of
    contemplating suicide or the inability to get out of bed. People
    so afflicted “have a lowgrade alienation feeling that something
    is missing, joylessness.” He opined that it usually has to do with
    genetic predisposition and problems in child rearing.
    Regarding PCP, Dr. Abrams said the drug is unlike almost
    any other abused drug because it makes people catatonic,
    insensible, and excitable. Dr. Abrams stated his opinion that
    the level of Mitchell’s drug test administered at the time of his
    arrest — PCP in the amount of 11 nanograms per milliliter —
    indicated Mitchell most likely smoked a substantial amount of
    21
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    PCP within the 24 to 72 hours before his arrest. Dr. Abrams
    explained that Mitchell’s blood level of PCP and his irrational,
    violent, senseless, and out-of-control behavior suggested that
    after noon on August 8, 2005, Mitchell’s behavior was strongly
    influenced by the effects of PCP. Dr. Abrams noted that one side
    effect of PCP is that it prevents the formation of memories. Dr.
    Abrams reported that Mitchell told him only that he “was
    driving around that day” and that he could not remember any
    involvement in the shootings. Dr. Abrams stated his view that
    Mitchell was intoxicated at the time of the shootings, but
    whether he acted with premeditation or malice “would be up for
    grabs.”
    II.    GUILT PHASE ISSUES
    A. CALJIC Nos. 8.71 and 8.72 Instructional Error
    1. Background
    Mitchell contends that his convictions for first degree
    murder, with the special circumstance finding, should be
    reversed because the jury was instructed incorrectly. Mitchell
    was found death-eligible based on the multiple-murder special
    circumstance, which required that he be convicted of at least one
    first degree murder and one second degree murder in the same
    proceeding. (§ 190.2, subd. (a)(3).) Mitchell was charged with
    three murders during the two incidents — first the killing of
    Lopez and Mawikere at CAS, and thereafter the killing of
    Susano Torres at the Yellows. The prosecution proceeded solely
    on the theory that all three homicides were premeditated and
    deliberate first degree murder. That is the only theory of first
    degree murder on which the jury was instructed.
    At the close of the guilt phase, the trial court gave the jury
    instructions on voluntary manslaughter, first degree murder,
    22
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    and second degree murder, as the various possible theories of
    crimes that the evidence at trial supported. The trial court then
    gave the jury the 1996 revised versions of CALJIC Nos. 8.71 and
    8.72. These instructions concern how the jury is to proceed if it
    finds reasonable doubt with respect to a greater offense.
    The given version of CALJIC No. 8.71 reads: “If you are
    convinced beyond a reasonable doubt and unanimously agree
    that the crime of murder has been committed by a defendant,
    but you unanimously agree that you have a reasonable doubt
    whether the murder was of the first or of the second degree, you
    must give defendant the benefit of that doubt and return a
    verdict fixing the murder as of the second degree.” The trial
    court appears to have slightly misstated the language of
    CALJIC No. 8.71 in its oral pronouncement by using the phrase
    “but you unanimously agree and you have a reasonable doubt”
    instead of “but you unanimously agree that you have a
    reasonable doubt.” But there does not appear to be any
    substantive difference between the two formulations that would
    have affected the outcome. (See People v. Osband (1996) 
    13 Cal. 4th 622
    , 717 [“as long as the court provides the jury with the
    written instructions to take into the deliberation room, they
    govern in any conflict with those delivered orally”].)
    The given version of CALJIC No. 8.72 reads: “If you are
    convinced beyond a reasonable doubt and unanimously agree
    that the killing was unlawful, but you unanimously agree that
    you have a reasonable doubt whether the crime is murder or
    manslaughter, you must give the defendant the benefit of that
    doubt and find it to be manslaughter rather than murder.”
    Mitchell contends that the 1996 versions are flawed and
    that these instructions lowered the prosecution’s burden of proof
    23
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    and undermined the proof beyond a reasonable doubt standard,
    thereby violating his state and federal constitutional rights.
    Specifically, Mitchell observes that the versions of the
    instructions required that in order for the jury to return a
    verdict on the lesser charge, the jury must “unanimously agree
    that [they] have a reasonable doubt” as to whether the
    defendant was guilty of the greater charge or lesser charge.
    Mitchell contends this conveyed to jurors who harbored
    reasonable doubt that unless the doubt was shared by all of the
    other jurors, the duty to give the benefit of the doubt did not
    arise. As such, this conveyed to the jury that first degree murder
    was the default finding and thus lowered the prosecution’s
    burden of proof by reassigning the benefit of the doubt to the
    prosecution.
    2. Analysis
    A claim of instructional error is reviewed de novo. (People
    v. Cole (2004) 
    33 Cal. 4th 1158
    , 1210.) An appellate court
    reviews the wording of a jury instruction de novo and assesses
    whether the instruction accurately states the law. (People v.
    Posey (2004) 
    32 Cal. 4th 193
    , 218.) In reviewing a claim of
    instructional error, the court must consider whether there is a
    reasonable likelihood that the trial court’s instructions caused
    the jury to misapply the law in violation of the Constitution.
    (Estelle v. McGuire (1991) 
    502 U.S. 62
    , 72 & fn. 4; People v.
    Lucas (2014) 
    60 Cal. 4th 153
    , 287.) The challenged instruction
    is viewed “in the context of the instructions as a whole and the
    trial record to determine whether there is a reasonable
    likelihood the jury applied the instruction in an impermissible
    manner.” (People v. Houston (2012) 
    54 Cal. 4th 1186
    , 1229.)
    24
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Preliminarily, because Mitchell failed to object below, his
    state law claims asserting error on the instructions have been
    forfeited. (See People v. Bolin (1998) 
    18 Cal. 4th 297
    , 327.) But
    failure to object to instructional error will not result in forfeiture
    if the substantial rights of the defendant are affected. (§ 1259;
    People v. Lucas (2014) 
    60 Cal. 4th 153
    , 287.) Here, Mitchell
    claims that the flawed instructions deprived him of due process,
    and because this would affect his substantial rights if true, his
    claim is not forfeited.
    In support of his claim, Mitchell cites People v. Moore
    (2011) 
    51 Cal. 4th 386
    , where we stated that “the better practice
    is not to use the 1996 revised versions of CALJIC Nos. 8.71 and
    8.72, as the instructions carry at least some potential for
    confusing jurors about the role of their individual judgments in
    deciding between first and second degree murder, and between
    murder and manslaughter.” (Id. at p. 411.) However, we
    expressly did not decide whether other jury instructions, such
    as CALJIC No. 17.40, dispel any confusion that might arise from
    CALJIC Nos. 8.71 and 8.72 because the jury in Moore had found
    true     burglary-murder      and     robbery-murder     special
    circumstances and thus had an alternative basis to find that the
    defendant was guilty of first degree murder. (Moore, at p. 412.)
    In this case, unlike in Moore, the prosecution only relied
    on the premeditation theory to prove the charge of first degree
    murder against Mitchell. We hold that the instructions as a
    whole made clear the role of the juror’s individual judgments in
    deciding between first and second degree murder, and between
    murder and manslaughter, thereby negating any potential
    confusion arising from CALJIC Nos. 8.71 and 8.72.
    25
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Mitchell’s principal complaint is that the instructions’
    reference to unanimity confused jurors into thinking that even
    if they had reasonable doubt as to the greater charge in the
    instruction, they should defer to another juror’s finding of no
    reasonable doubt. We rejected a similar argument in People v.
    Salazar (2016) 
    63 Cal. 4th 214
    , 246–248 (Salazar). The only
    pertinent difference between Salazar and this case is that the
    trial court in Salazar instructed the jury with CALJIC No. 17.10
    and omitted CALJIC No. 2.61. But Salazar remains relevant
    and instructive in its determination that “while we have
    disapproved the unanimity terminology in the 1996 revised
    versions of CALJIC Nos. 8.71 and 8.72 because of the potential
    for confusion, the instructions were not erroneous in this case
    when considered with the rest of the charge to the jury.” (Salazar,
    at p. 248, italics added.) Mitchell contends that the instructions
    conveyed that “[i]f just one juror was convinced the homicides
    were the greater offense, then the other eleven jurors, who did
    have doubt that it was murder or first degree murder, would
    have no obligation to vote for the lesser offense.” However, the
    jury was instructed with CALJIC No. 17.40, which made clear
    that “[t]he People and the defendant are entitled to the
    individual opinion of each of you. . . . Each of you must decide
    the case for yourself, but do so only after discussing the evidence
    and the instructions with your fellow jurors.” (Italics added.)
    (See People v. Buenrostro (2018) 6 Cal.5th 367, 430 [“In the
    scenario defendant envisions, a jury’s reasonable understanding
    of the instructions as a whole would result in a hung jury, not a
    directed verdict for first degree murder”].)
    Mitchell’s further arguments that CALJIC Nos. 8.71 and
    8.72 improperly shifted the burden from the prosecution or set
    first degree murder as the default finding are similarly
    26
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    unavailing.    With regard to the prosecution’s burden of
    persuasion, the jury was instructed with CALJIC No. 2.61,
    which made clear that the prosecution must prove beyond a
    reasonable doubt every element or charge against Mitchell.
    Also, in addition to CALJIC Nos. 8.71 and 8.72, the jury was
    instructed with CALJIC No. 8.74, which explains the
    determinations that the jury must unanimously make in order
    to render a guilty verdict for first degree murder: “Before you
    may return a verdict in this case you must agree unanimously
    not only as to whether the defendant is guilty or not guilty, but
    also if you should find him guilty of an unlawful killing, you
    must agree unanimously as to whether he is guilty of murder of
    the first degree or murder of the second degree or voluntary
    manslaughter.” This instruction makes clear that the jury must
    unanimously find that the defendant was “guilty of murder of
    the first degree or murder of the second degree or voluntary
    manslaughter,” without preferring any of the options.
    Mitchell argues that these other instructions fail to rectify
    the potential confusion because CALJIC Nos. 8.71 and 8.72 are
    the more specific instructions and thus, insofar as there was an
    inconsistency between CALJIC Nos. 8.71 and 8.72 and other
    instructions, the jury would have applied CALJIC Nos. 8.71 and
    8.72. This is mistaken. Although it is true that CALJIC
    Nos. 8.71 and 8.72 are more specific in addressing the crimes
    with which Mitchell was charged, they are not more specific
    than CALJIC Nos. 17.40, 2.61, and 8.74 in addressing the
    subject matter at issue.
    For each of the possible sources of confusion identified by
    Mitchell in CALJIC Nos. 8.71 and 8.72, the other jury
    instructions — CALJIC Nos. 17.40, 2.61, and 8.74 — addressed
    27
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    those points more specifically: As to any potential confusion
    about whether each juror was to exercise his or her individual
    judgment or defer to another juror’s judgment on whether there
    is reasonable doubt that Mitchell committed the greater crime,
    CALJIC No. 17.40 made clear that jurors are required to
    exercise their individual judgment in making this
    determination. CALJIC No. 2.61 more specifically addressed
    whether the prosecution bore the burden of proving the
    elements of the greater crimes; it expressly stated that the
    prosecution bears the burden to prove beyond a reasonable
    doubt every element or charge against Mitchell. And CALJIC
    No. 8.74 more specifically addressed whether the jury is to treat
    first degree murder as the default finding; it explained that the
    jury must be unanimous in deciding whether the defendant is
    guilty of first degree murder, second degree murder, or
    manslaughter, with no default among them. (See People v.
    Gomez (2018) 6 Cal.5th 243, 302 [any juror confusion arising
    from CALJIC No. 8.71 was remedied by CALJIC Nos. 17.40 and
    8.74].)
    We find no error in the jury instructions because when
    they are viewed as a whole, there is no reasonable likelihood
    that they caused the jury to misapply the law in violation of the
    Constitution.
    B. CALJIC No. 8.73.1 Instructional Error
    1. Background
    Mitchell next contends that the trial court erred in
    refusing to instruct the jury pursuant to CALJIC No. 8.73.1. On
    August 3, 2006, at the guilt phase jury instruction conference,
    defense counsel requested that the trial court give CALJIC No.
    28
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    8.73.1. That instruction states: “A hallucination is a perception
    that has no objective reality. [¶] If the evidence establishes that
    the perpetrator of an unlawful killing suffered from a
    hallucination which contributed as a cause of the homicide, you
    should consider that evidence solely on the issue of whether the
    perpetrator killed with or without deliberation and
    premeditation.” (CALJIC No. 8.73.1.)
    Without immediately deciding the question, the trial court
    first noted that there was no medical evidence that Mitchell was
    hallucinating, but that there was evidence that Mitchell was
    “yelling about shooting the devil” and that Armando Torres had
    tattoos of horns on his head. The prosecutor argued that
    because Armando actually had horn tattoos, Mitchell’s
    statements about shooting the devil were not hallucinations.
    Defense counsel countered that despite the tattoos, Mitchell’s
    statements about shooting the devil did not necessarily refer to
    Torres. The prosecutor agreed that Mitchell may not have been
    referring to Armando. The trial court then deferred deciding the
    issue to hear counsel’s arguments on the applicability of People
    v. Padilla (2002) 
    103 Cal. App. 4th 675
    , a case cited in reference
    to CALJIC No. 8.73.1.
    On August 7, 2006, when the trial court revisited the
    issue, defense counsel informed the trial court that Mitchell had
    instructed him “not to present a psychiatric defense or a drug
    defense” at the guilt phase and that he had decided for tactical
    reasons not to oppose his client’s decision. However, defense
    counsel stated that he was still requesting that CALJIC No.
    8.73.1 be given. The prosecutor maintained that the evidence
    only arguably showed that Mitchell might have been under the
    influence of some drug on August 9, 2005, the day after the
    29
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    charged homicides. Thus, the prosecutor argued that the
    instruction was irrelevant. The trial court agreed and refused
    to give the instruction.
    Mitchell argues that there was evidence that he was
    suffering from hallucinations during the shootings of August 8,
    2005, evidenced by the fact that he called Armando “devil” and
    that he was behaving erratically the next day, including making
    statements that he had killed the devil. Accordingly, he claims
    that the jury should have been instructed and consequently
    could have determined that there was no deliberation or
    premeditation in the homicides. Mitchell claims that the trial
    court’s denial of his requested instruction violated state law and
    his due process right to a fair trial and a meaningful opportunity
    to present a defense.
    2. Analysis
    In general, a trial court must give a requested jury
    instruction if there is substantial evidence in the record
    supporting such an instruction. (See People v. Cunningham
    (2001) 
    25 Cal. 4th 926
    , 1008 [so holding with respect to
    instructions on lesser included offenses].) “In determining
    whether the evidence is sufficient to warrant a jury instruction,
    the trial court does not determine the credibility of the defense
    evidence, but only whether ‘there was evidence which, if
    believed by the jury, was sufficient to raise a reasonable doubt.’ ”
    (People v. Salas (2006) 
    37 Cal. 4th 967
    , 982.) “On appeal, we
    likewise ask only whether the requested instruction was
    supported by substantial evidence — evidence that, if believed
    by a rational jury, would have raised a reasonable doubt as to”
    an element of the crime in question. (People v. Mentch (2008) 
    45 Cal. 4th 274
    , 288.
    30
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Here, there was not sufficient evidence to warrant the trial
    court giving the requested instruction at the time of the request.
    Mitchell points to only two facts that could support the
    requested instruction: (1) that he called Armando Torres “devil”
    before shooting him; and (2) that he was behaving erratically,
    possibly under the influence of PCP, on the day after his
    shooting sprees, including making statements that he had killed
    the devil. Notably, at the guilt phase, counsel chose not to
    present a psychiatric or drug defense and did not dispute the
    trial court’s statement that there was no medical evidence of
    hallucination.
    The fact that Mitchell called Armando “devil” does not
    alone provide sufficient evidence that Mitchell was
    hallucinating. In using the term “devil,” Mitchell may have been
    referring to Armando because of his horn tattoos. Moreover,
    although Armando initially testified on direct examination that
    Mitchell had never called him the devil before, later on redirect
    Armando stated that Mitchell “always” called him the devil
    despite Armando telling him not to.
    Mitchell’s erratic behavior on the day after the shootings
    also does not show he was suffering from hallucinations. Even
    assuming Mitchell was under the influence of PCP on August 9,
    2005, both parties agree that there is no medical evidence in the
    record to indicate that he was under the influence on the day of
    the shootings. Mitchell also presented no evidence that he had
    suffered hallucinations during any prior use of PCP. Mitchell
    notes he was “crazily” shooting his gun into the air, screaming
    about killing the devil and being the devil, and saying that God
    would not judge him for killing the devil. But Mitchell’s
    indiscriminate shooting into the air does not imply he was
    31
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    hallucinating, and his usage of the word “devil” does not imply
    that he was in fact perceiving a “devil” as opposed to simply
    referring to the concept or referring to Armando by a nickname.
    The cases Mitchell relies upon to support this claim
    offered significantly more compelling evidence that a defendant
    suffered from hallucinations, including medical evidence. (See
    People v. Mejia-Lenares (2006) 
    135 Cal. App. 4th 1437
    , 1444
    [medical evidence showed defendant was diagnosed with major
    depression with “psychotic features, including delusions,” and
    defendant testified that he suffered specific hallucinations in
    which he witnessed the victim transforming into the devil];
    People v. Duckett (1984) 
    162 Cal. App. 3d 1115
    , 1118 [medical
    expert testified that defendant suffered from chronic paranoid
    schizophrenia and that defendant experienced “ ‘command
    hallucinations’ ” in an “acute phase” of his illness at the time of
    the killing]; People v. Pennington (1967) 
    66 Cal. 2d 508
    , 512
    [medical expert testified, in the context of assessing defendant’s
    competence for trial, that defendant was suffering from
    hallucinations indicative of schizophrenia and stated that “he
    had observed defendant go into a fit of ‘psychotic furor’ ”].)
    It is of course possible that Mitchell was hallucinating, but
    a mere possibility is not enough. There must be substantial
    evidence to warrant the instruction. In light of the absence of
    evidentiary support for Mitchell’s argument, coupled with the
    support for the alternative explanation, we believe no
    reasonable jury would have credited Mitchell’s explanation. The
    trial court’s refusal to instruct the jury with CALJIC No. 8.73.1
    did not deny Mitchell his due process rights to a fair trial or a
    meaningful opportunity to present a defense.
    32
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    C. Cumulative Error at the Guilt Phase
    Because we reject Mitchell’s claims of error at the guilt
    phase, there is no cumulative error requiring reversal of his
    convictions.
    III.   PENALTY PHASE ISSUES
    A. CALJIC No. 2.20 Instructional Error
    1. Background
    Mitchell contends the trial court erred at the penalty
    phase by failing to instruct the jury properly on witness
    credibility. At the jury instructions hearing for the penalty
    phase, the trial court discussed CALJIC No. 2.20, the jury
    instruction addressing what jurors may consider in assessing
    witness credibility. That pattern instruction says: “Every
    person who testifies under oath [or affirmation] is a witness.
    You are the sole judges of the believability of a witness and the
    weight to be given the testimony of each witness. [¶] In
    determining the believability of a witness you may consider
    anything that has a tendency reasonably to prove or disprove
    the truthfulness of the testimony of the witness, including but
    not limited to any of the following: [¶] The extent of the
    opportunity or ability of the witness to see or hear or otherwise
    become aware of any matter about which the witness testified;
    [¶] The ability of the witness to remember or to communicate
    any matter about which the witness has testified; [¶] The
    character and quality of that testimony; [¶] The demeanor and
    manner of the witness while testifying; [¶] The existence or
    nonexistence of a bias, interest, or other motive; [¶] The
    existence or nonexistence of any fact testified to by the witness;
    [¶] The attitude of the witness toward this action or toward the
    giving of testimony[.][;] [¶] [A statement [previously] made by
    33
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    the witness that is [consistent] [or] [inconsistent] with [his] [her]
    testimony][.][;] [¶] [The character of the witness for honesty or
    truthfulness or their opposites][;] [¶] [An admission by the
    witness of untruthfulness][;] [¶] [The witness’ prior conviction of
    a felony][;] [¶] [Past criminal conduct of a witness amounting to
    a misdemeanor][;] [¶] [Whether the witness is testifying under
    a grant of immunity].” (CALJIC No. 2.20.)
    The last six paragraphs of CALJIC No. 2.20 may be
    omitted based on the evidence presented at trial. In discussion
    with counsel, the trial court reviewed whether evidence
    supported the inclusion of any of the six bracketed paragraphs
    in the instruction. The trial court stated that “no witness had a
    felony conviction,” defense counsel agreed, and the prosecutor
    remained silent. As a result, the trial court fashioned an
    instruction, ultimately delivered to the jury, which eliminated
    the last six paragraphs of the pattern CALJIC No. 2.20
    instruction, as well as the reference to “affirmation” in the
    instruction’s introductory paragraph.
    It appears that the trial court and the parties failed to
    recall that witness Armando Torres, who testified for the
    prosecution at the guilt phase and would testify at the penalty
    phase, had admitted that he had been convicted of felony
    robbery. As a result, the penalty phase jury was not instructed
    that a witness’s prior conviction of a felony bore on his
    credibility, as set forth in CALJIC No. 2.20 and CALJIC
    No. 2.23. Although the jury did receive the version of CALJIC
    No. 2.20 containing the language pertaining to felony
    convictions as well as CALJIC No. 2.23 at the guilt stage, the
    jury was specifically instructed at the penalty phase to
    disregard the guilt phase instructions.
    34
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    Consequently, Mitchell contends the incomplete
    instructions denied his state and federal constitutional rights to
    a fair penalty trial, due process, and a fair penalty
    determination mandating the reversal of his death judgment.
    We reject this claim, as the error in failing to reinstruct on
    principles relating to evaluating the credibility of a witness in
    the penalty phase was harmless beyond a reasonable doubt.
    2. Analysis
    “A trial court has a sua sponte duty to ‘instruct on general
    principles of law that are closely and openly connected to the
    facts and that are necessary for the jury’s understanding of the
    case,’ including instructions relevant to evaluating the
    credibility of witnesses.” (People v. Blacksher (2011) 52 Cal.4th
    769,845–846; see also §§ 1093, subd. (t), 1127.) This duty
    includes giving correct instructions regarding the credibility of
    witnesses. As we have stated, “[T]he court should give the
    substance of CALJIC No. 2.20 in every criminal case, although
    it may omit factors that are inapplicable under the evidence.”
    (People v. Horning (2004) 
    34 Cal. 4th 871
    , 910.)
    As discussed, Mitchell’s counsel assented to the trial
    court’s formulation of CALJIC No. 2.20, omitting the bracketed
    language regarding a witness’s prior felony convictions.
    Therefore, any claim of state law error has been forfeited and
    has not been preserved for appeal. (People v. 
    Bolin, supra
    , 18
    Cal.4th at p. 328.) That said, under section 1259, a reviewing
    court has the authority to review any question of law involving
    an instruction if the defendant’s substantial rights were
    affected, notwithstanding a failure to preserve the issue for
    appeal. Thus, we will consider Mitchell’s claim that the
    35
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    omission of the portion of CALJIC No. 2.20 was constitutional
    error.
    Here, any error in the failure to instruct the jury on the
    impact of a felony conviction on a witness’s credibility was
    undoubtedly harmless beyond a reasonable doubt. The jury was
    aware that Armando was a felon, as he testified at the guilt
    phase that he had a prior felony conviction for robbery. The jury
    was instructed that it could consider evidence from any phase of
    the trial, and although the jury was not specifically instructed
    about the impact of felony convictions on a witness’s credibility,
    the jury was instructed that it could “consider anything that has
    a tendency reasonably to prove or disprove the truthfulness of
    the testimony of the witness.” Thus, the jury was well appraised
    of Armando’s felony conviction and equipped to assess
    Armando’s credibility in light of his criminal past.
    Moreover, the subject of Armando’s testimony at the
    penalty phase was not controversial. Armando testified that he
    liked his younger brother and missed him. He testified that
    when he thinks about his brother, he uses drugs to make his
    thoughts go away, that his methamphetamine use has gotten
    worse, and that as a result he has ended up in custody. The jury
    was also made aware that Armando was currently in custody
    relating to charges involving great bodily injury, drugs, and a
    firearm. The fact that Armando was a convicted felon at the
    time of his testimony bore little relevance to the subject of his
    testimony about how Susano’s murder had affected his life.
    Furthermore, given what the jury knew about Armando’s drug
    use and criminal behavior, the fact that his prior felony
    conviction was not specifically called to the jury’s attention had
    marginal relevance in negatively impacting Armando’s
    36
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    credibility. Consequently, it is not reasonably possible that the
    jury would not have returned a death verdict had it been
    expressly told it could consider Armando’s felony conviction in
    assessing his credibility.
    B. Constitutionality of California’s Death Penalty
    Statute
    Mitchell raises several constitutional challenges to
    California’s death penalty scheme. We have rejected these
    claims before, as follows, and we decline to revisit our prior
    holdings:
    “The death penalty law adequately narrows the class of
    death-eligible defendants.” (People v. Boyce (2014) 
    59 Cal. 4th 672
    , 723; 
    Salazar, supra
    , 63 Cal.4th at p. 255.)
    Consideration of the circumstances of the crime during the
    penalty phase pursuant to section 190.3, factor (a), does not
    result in an arbitrary and capricious application of the death
    penalty and does not violate the Fifth, Sixth, Eighth, and
    Fourteenth Amendments to the federal Constitution. (People v.
    Winbush (2017) 2 Cal.5th 402, 489 (Winbush); see also Tuilaepa
    v. California (1994) 
    512 U.S. 967
    , 976 [§ 190.3, factor (a) does
    not violate the Eighth Amendment and is not unconstitutionally
    vague].)
    The jury need not make findings beyond a reasonable
    doubt that aggravating factors were present (other than Penal
    Code section 190.3, factor (b) or (c) evidence), that they
    outweighed the mitigating factors, or the factors were
    substantial enough to warrant a judgment of death under
    Apprendi v. New Jersey (2000) 
    530 U.S. 466
    , Blakely v.
    Washington (2004) 
    542 U.S. 296
    , Ring v. Arizona (2002) 
    530 U.S. 584
    , and Cunningham v. California (2007) 
    549 U.S. 270
    . (See
    37
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    People v. Merriman (2014) 
    60 Cal. 4th 1
    , 106; People v. Griffin
    (2004) 
    33 Cal. 4th 1015
    ; People v. Blair (2005) 
    36 Cal. 4th 686
    ,
    753.)
    The federal Constitution does not require the court to
    instruct the jury that the prosecution has the burden of
    persuasion regarding the existence of aggravating factors, nor is
    the court required to instruct the jury that there is no applicable
    burden of proof. (People v. Mendoza (2016) 
    62 Cal. 4th 856
    , 916;
    People v. Lenart (2004) 
    32 Cal. 4th 1107
    , 1136–1137; People v.
    Holt (1997) 
    15 Cal. 4th 619
    , 682–684.)
    The jury is not required to unanimously find that certain
    aggravating factors warrant the death penalty under the federal
    Constitution, and the equal protection clause does not compel a
    different result. (People v. Enraca (2012) 
    53 Cal. 4th 735
    , 769;
    People v. Casares (2016) 
    62 Cal. 4th 808
    , 854.) The court is also
    not required to instruct the jury that it need not unanimously
    find particular facts in mitigation. (People v. Cage (2015) 
    62 Cal. 4th 256
    , 293 (Cage).)
    CALJIC No. 8.88 does not improperly instruct the jury
    that a verdict of death is required if the factors in aggravation
    outweigh the factors in mitigation. (People v. Arias (1996) 
    13 Cal. 4th 92
    , 170–171.)
    The use of adjectives like “extreme” and “substantial” in
    the list of mitigating factors in section 190.3 does not act as a
    barrier to the jury’s consideration of mitigating evidence in
    violation of the federal Constitution. (People v. McKinnon
    (2011) 
    52 Cal. 4th 610
    , 692; People v. Avila (2006) 
    38 Cal. 4th 491
    ,
    614–615.)
    The court’s use of CALJIC No. 8.88, which instructs that
    jurors must be “persuaded that the aggravating circumstances
    38
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    are so substantial in comparison with the mitigating
    circumstances” to warrant a death judgment, is not
    unconstitutionally vague, appropriately informs jurors, and
    does not violate the Eighth and Fourteenth Amendments to the
    federal Constitution. (People v. Landry (2016) 2 Cal.5th 52,
    122–123 (Landry); People v. Williams (2016) 1 Cal.5th 1166,
    1204–1205.)
    The trial court has no obligation to delete from CALJIC
    No. 8.85 inapplicable mitigating factors, nor must it identify
    which factors are aggravating and which are mitigating. (People
    v. Cook (2006) 
    39 Cal. 4th 566
    , 618; People v. Hillhouse (2002) 
    27 Cal. 4th 469
    , 509 [“The aggravating or mitigating nature of the
    factors is self-evident within the context of each case.”].) “We
    again conclude that the instruction is ‘not unconstitutional for
    failing to inform the jury that: (a) death must be the appropriate
    penalty, not just a warranted penalty [citation]; (b) [a sentence
    of life without the possibility of parole] is required, if it finds that
    the mitigating circumstances outweigh those in aggravation
    [citation] or that the aggravating circumstances do not outweigh
    those in mitigation [citation]; (c) [a sentence of life without the
    possibility of parole] may be imposed even if the aggravating
    circumstances outweigh those in mitigation [citation]; (d)
    neither party bears the burden of persuasion on the penalty
    determination.’ ” 
    (Landry, supra
    , 2 Cal.5th at p. 122.)
    “The 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; People v. Smithey (1999) 
    20 Cal. 4th 936
    , 1000 [“ ‘Sympathy for a defendant’s family is not a
    matter that a capital jury can consider in mitigation’ ”].)
    39
    PEOPLE v. MITCHELL
    Opinion of the Court by Liu, J.
    The trial court need not instruct the jury that life without
    parole was presumed the appropriate sentence; “[t]here is no
    requirement jurors be instructed there is a ‘ “ ‘presumption of
    life’ ” ’ or that they should presume life imprisonment without
    the possibility of parole is the appropriate sentence.” (People v.
    Parker (2017) 2 Cal.5th 1184, 1233.) And “[j]urors need not
    make written findings in determining penalty.” (People v.
    Valdez (2012) 
    55 Cal. 4th 82
    , 180.)
    The federal Constitution does not require intercase
    proportionality review among capital cases. 
    (Winbush, supra
    , 2
    Cal.5th at p. 490; see Pulley v. Harris (1984) 
    465 U.S. 37
    , 50–
    51.) “California’s death penalty law does not violate equal
    protection by treating capital and noncapital defendants
    differently.” (People v. Sánchez (2016) 
    63 Cal. 4th 411
    , 488.)
    California’s use of the death penalty does not violate
    international law, the federal Constitution, or the Eighth
    Amendment’s prohibition against cruel and unusual
    punishment in light of “evolving standards of decency.” 
    (Cage, supra
    , 62 Cal.4th at p. 297; see People v. Zamudio (2008) 
    43 Cal. 4th 327
    , 373.)
    IV.    CUMULATIVE ERROR
    Because we have only found one error in the proceeding —
    at the penalty phase regarding the trial court’s failure to
    instruct the jury that a witness’s prior conviction of a felony bore
    on his credibility — and because we have determined that the
    error was harmless beyond a reasonable doubt, we find there is
    no cumulative error requiring reversal of Mitchell’s convictions
    or penalty of death.
