    v.
    DORA BUENROSTRO,
    Defendant and Appellant.
    S073823
    Riverside County Superior Court
    CR59617
    December 3, 2018
    Justice Kruger filed the opinion of the court, in which Chief
    Justice Cantil-Sakauye and Justices Chin, Corrigan, Liu,
    Cuéllar, and Mauro* concurred.

    Associate Justice of the Court of Appeal, Third Appellate
    District, assigned by the Chief Justice pursuant to article VI,
    section 6 of the California Constitution.
    PEOPLE v. BUENROSTRO
    S073823
    Opinion of the Court by Kruger, J.
    After a jury found defendant Dora Buenrostro competent
    to stand trial, a separate jury convicted her of the first degree
    murders of her children, Susana, Vicente, and Deidra. (Pen.
    Code, § 187.) The jury found true three multiple-murder
    special-circumstance allegations (id., § 190.2, subd. (a)(3)) and
    allegations that defendant personally used a knife in the
    commission of each murder (id., §§ 1192.7, subd. (c)(23), 12022,
    subd. (b)). After a penalty trial, the same jury returned a verdict
    of death. The trial court denied defendant’s motion for a new
    trial and for modification of the verdict (id., § 190.4, subd. (e))
    and sentenced her to death. This appeal is automatic. (Id.,
    § 1239, subd. (b).)
    We affirm the judgment as to guilt, vacate two of the three
    multiple-murder special-circumstance findings, reverse the
    judgment as to the sentence of death, and remand the matter
    for a new penalty determination.
    I. FACTS
    A. Guilt Phase
    The bodies of the three victims were found on October 27,
    1994. Each victim had suffered fatal stab wounds. Beginning
    on that date and continuing through her trial testimony,
    defendant blamed the murders on her estranged husband,
    1
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Alejandro Buenrostro (who was known as Alex). In closing
    argument, however, the defense conceded that Alex, who had an
    alibi, could not have killed the children. The guilt phase focused
    on whether there was sufficient evidence to establish that
    defendant committed the murders and did so willfully and with
    premeditation and deliberation.
    1. Prosecution Evidence
    Defendant and Alex were married in 1982. Until their
    separation several years later, they lived in Los Angeles with
    their three children, Susana, Vicente, and Deidra (ages nine,
    eight, and four, respectively, at the time of the murders). Alex
    worked as an auto refinisher painter, and defendant worked for
    seven years as a file clerk and interpreter for a law firm. In
    1990, defendant moved with the children to San Jacinto in
    Riverside County. Alex remained at the Los Angeles residence
    and saw the children twice a month.
    a. Events of Tuesday, October 25, 1994
    Between 5:00 and 6:30 p.m. on Tuesday, October 25, 1994,
    defendant was seen driving in her car with her three children.
    Around 6:30 p.m., defendant borrowed $10 from a neighbor,
    David Tijerina, for gasoline because she was going to drive to
    Los Angeles to see her husband. Tijerina watched defendant
    drive out of the apartment complex with Deidra in the car.
    Defendant arrived at Alex’s residence in Los Angeles,
    alone and unannounced, about 11:00 p.m. and stayed for two
    hours. She asked to see Alex’s gun. He removed the bullets,
    showed her the gun, and then put it away. He asked defendant
    about the children, and she told him they were fine. At some
    point, defendant went to the kitchen and then approached Alex,
    who was in the bedroom. She was holding a steak knife and
    2
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    wearing a red glove. She made stabbing motions with the knife
    and asked Alex why he was afraid of dying. She threatened to
    hit him where “it hurts the most” because he had “never given
    her our separation.” He called 911. Defendant swung at him
    with the knife a couple of times, but he was able to get away and
    ran outside.
    Police arrived within 20 minutes, at 1:15 a.m. Defendant
    was standing in the doorway of the residence, holding the knife,
    but complied when police commanded her to drop it. She told
    the police she was there to pick up her child, whom she accused
    Alex of taking to buy shoes earlier in the day and not returning.
    The police observed no children at the residence or in
    defendant’s car, a dark-colored four-door Oldsmobile lacking a
    child’s car seat. The police advised her to return to San Jacinto
    and file a missing child report, and she left.
    b. Events of Wednesday, October 26, 1994
    On Wednesday, October 26, 1994, about 10:30 a.m.,
    defendant went to the San Jacinto Police Department and
    reported to Officer Blane Dillon that her estranged husband had
    taken her youngest child two days earlier and not brought her
    back. The officer informed her law enforcement could not
    intervene unless her husband was in violation of a court order
    providing he was not permitted to visit with the child.
    Defendant left the police department.
    Later that day, about 2:00 p.m., defendant’s sister, Angela
    Montenegro, saw her at a gas station in San Jacinto. Defendant
    was alone and driving her black Oldsmobile, which had been
    washed and had water dripping from the back bumper. Neither
    Deidra nor a child’s car seat was in the car. About 3:00 p.m.,
    defendant’s next door neighbor, Velia Cabanila, saw Susana and
    3
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Vicente when they stopped briefly to play at her apartment after
    school. The children told Cabanila their mother had told them
    Deidra was with their father. Deidra had visited Cabanila’s
    apartment the day before, by herself. About 7:00 p.m., another
    neighbor saw defendant looking over the wall of her apartment.
    c. Events of Thursday, October 27, 1994
    Cabanila’s and defendant’s apartments shared a common
    wall. On Thursday, October 27, 1994, about 3:00 a.m., Cabanila
    heard a “really loud thump,” but no other noise, coming from
    defendant’s living room.
    At 6:40 a.m., defendant entered the San Jacinto Police
    Department and reported to the desk clerk her husband was at
    her apartment with a knife.          Police were immediately
    dispatched. The officers entered the apartment and found two
    of defendant’s children, Susana and Vicente, lying on separate
    sofas in the living room, each covered as if sleeping. Both were
    dead, with stab wounds to their necks. Another sofa was
    standing on its end at the entrance to the hallway, blocking the
    path to the bedrooms and the bathroom. Defendant admitted
    she had moved the sofa.
    Outside, defendant told police Alex had come to the
    apartment that morning. She let him in, and he went to the
    bathroom. Defendant thought he was acting strange, so she
    went to the police station to notify the police of his behavior.
    San Jacinto Police Detective Sergeant Frederick
    Rodriguez was assigned as lead investigator. At the police
    station, he interviewed defendant, who was not in custody.
    Meanwhile, police focused their investigation on Alex. By 9:00
    a.m., police located him at the office of his employer in Los
    Angeles and took him into police custody for questioning. By
    4
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    early the next morning, the police ruled him out as a suspect
    and released him from custody.2
    Later, around 6:00 p.m., Deidra’s body was discovered by
    children playing in an abandoned post office in Lakeview. A
    deputy with the Riverside County Sheriff’s Department
    responded to the scene and saw Deidra strapped in a child’s car
    seat. There was blood and visible trauma to her mouth and
    neck. An object with a handle, possibly a screwdriver or pen
    knife, was stuck in her throat.
    Officer Dillon arrived at the scene about 7:30 p.m. to
    investigate.     He had received information about the
    investigation from other officers during the course of the day.
    Based on inconsistencies in defendant’s versions of events,
    police focused on her as a suspect.3
    d. Physical evidence
    Defendant’s car was removed from her apartment complex
    and processed for evidence. Her purse and camera case and a
    red knit glove were discovered in the trunk of the car. DNA
    testing established that six blood samples obtained from
    2
    Police spoke with Alex’s neighbor, who confirmed (as she
    did at trial) she had heard his shower running the morning of
    Thursday, October 27, and saw him leave his residence about
    7:20 a.m. Given the distance between defendant’s apartment in
    San Jacinto and Alex’s workplace in Los Angeles, as well as the
    time defendant reported Alex was at her apartment in
    possession of a knife (6:40 a.m.), Alex was ruled out as a suspect.
    3
    Detective Rodriguez’s interview of defendant began
    around 10:30 a.m., shortly after the bodies of Susana and
    Vicente were discovered in her apartment. A tape recording of
    the entire interview was played for the jurors. A transcript of
    the recording was also given to the jurors.
    5
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    defendant’s car matched Deidra’s DNA profile. Defendant, Alex,
    Susana, and Vicente were eliminated as sources for the blood.
    Hairs found on Deidra’s hand and leg were determined to
    be similar to defendant’s. Tire impressions lifted from an area
    near the abandoned post office where Deidra’s body was found
    matched the tread designs of the three different types of tires on
    defendant’s car.
    e. Autopsy results
    All three children bled to death from multiple stab wounds
    to the neck. Susana suffered defensive wounds to her right
    hand; four stab wounds to the front of her neck, two of which
    went into the bone of her spine; superficial cuts to her neck; and
    a perforation of her left chest cavity. The stab wounds ranged
    in depth from one to three inches. One stab wound severed the
    left subclavian artery and another cut halfway through the
    external jugular vein. These two injuries caused exceedingly
    rapid bleeding and likely rendered Susana unconsciousness in
    less than a minute.
    Vicente suffered numerous defensive wounds on his
    hands, two stab wounds to the front of his neck, and abrasions
    and contusions on his neck and right clavicle. One of the stab
    wounds cut almost completely through the right common carotid
    artery, which comes from the heart. Vicente died from rapid
    bleeding, which likely rendered him unconsciousness in less
    than a minute.
    Deidra died from multiple stab wounds to her neck. A
    piece of a knife blade three-quarters of an inch wide by two to
    three inches in length had broken off and was embedded in the
    bone in her neck area. A metallic tip of what appeared to be a
    ballpoint pen was found in the soft tissue of her neck. Deidra
    6
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    had suffered a perforation of the chest cavity and blunt force
    trauma to her skull, which was consistent with her head being
    slammed against the car seat while she was being stabbed.
    There were no defensive wounds on her body. Deidra’s body
    exhibited signs of decomposition. The time of her death could
    not be determined.
    2. Defense Evidence
    Defendant testified in her own defense. On direct
    examination, she testified that the last time she saw Deidra was
    9:00 or 10:00 a.m. on Tuesday, October 25, 1994, when Alex
    came to her apartment and took her. Between 11:00 a.m. and
    noon, defendant went to the San Jacinto Police Department to
    report Deidra missing. At 11:00 p.m. that night, defendant
    drove to Alex’s residence in Los Angeles and checked the house
    for Deidra. She picked up a knife to defend herself during an
    argument with Alex. She threatened him but did not try to stab
    him, and she denied that she wore a red glove on her hand. Alex
    called the Los Angeles Police, and defendant dropped her knife
    when ordered to do so. She complained to police that Alex had
    taken Deidra and had not returned her. When the police
    advised her to leave, she left and returned to San Jacinto. The
    following morning, defendant went to the San Jacinto Police
    Department       seeking    assistance      regarding   Deidra’s
    disappearance.
    Defendant testified that at 5:00 a.m. on Thursday
    morning, October 27, 1994, Alex came to her apartment. When
    she let him in, he went straight to the bathroom. Defendant left
    the apartment because of the Tuesday evening altercation with
    him in Los Angeles. She left Susana and Vicente in the
    apartment. She arrived at the police department between 5:30
    7
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    and 6:00 a.m., telling police she had had an argument with Alex
    on Tuesday and he had taken her daughter. She asked them to
    check her apartment and speak with Alex. Defendant said he
    did not have a knife or other weapon.
    Defendant returned to her apartment complex with the
    police and waited outside. About 7:30 a.m., she was informed
    her children were dead.         Defendant went to the police
    department, where she remained all day for questioning. She
    denied killing the children, claiming someone had planted the
    blood evidence in her car. She had no explanation for the tire
    impressions that matched the tires on her car and said the red
    gloves found in the passenger compartment and trunk of her car
    belonged to a Betty Buenrostro. Defendant admitted having a
    prior felony conviction for grand theft.
    B. Penalty Phase
    1. Prosecution Evidence
    The prosecution presented evidence of defendant’s prior
    conviction for grand theft, her violent conduct while
    incarcerated, and the impact of the murders on the victims’
    family members and on the community.
    a. Prior felony convictions (Pen. Code, § 190.3,
    factor (c))
    The parties stipulated that defendant pleaded guilty to
    felony grand theft (Pen. Code, § 487.1) on September 1, 1988.
    b. Prior unadjudicated criminal activity involving
    the use of or express or implied threat to use
    force or violence (Pen. Code, § 190.3, factor (b))
    In February 1995, while awaiting trial in this case,
    defendant had a physical altercation with Deputy Johnnie
    Anaya and a nurse who was administering medications to
    8
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    inmates housed on the medical floor in the jail. The altercation
    occurred when defendant stepped outside her cell, refused an
    order to return to her cell, and raised her hand to the deputy
    and nurse. Defendant grabbed the nurse’s arm and, when her
    hand slipped, held tightly onto her sleeve. Anaya forced
    defendant back into her cell. The deputy and defendant
    struggled, fell to the floor, and struggled further before other
    deputies subdued defendant.4
    Another incident occurred in May 1996.             Deputy
    Stephanie Rigby was supervising inmates at the jail and
    permitted defendant to leave the day room. Defendant walked
    into a sally port area and removed a wringer from a custodial
    mop bucket. Observing her from a glass-enclosed control room,
    Deputy Rigby commanded her to return to the day room.
    Defendant refused to comply and held the mop wringer over her
    shoulder like a baseball bat. When she refused to drop the
    wringer, back-up deputies were called to assist. A deputy had
    to physically remove the wringer from her grip. Defendant did
    not attempt to hit any of the deputies with the wringer.5
    c. Victim impact testimony
    The prosecution presented the testimony of the victims’
    older half-sister, Alejandra Buenrostro, their father, Alex
    Buenrostro, and Deborah De Forge, the principal of the
    4
    The trial court ruled evidence of the incident admissible
    under Penal Code section 190.3, factor (b), as showing a battery
    (id., § 242) involving the express or implied use of force or
    violence, or the threat of force or violence.
    5
    The trial court ruled the incident admissible under Penal
    Code section 190.3, factor (b), as misdemeanor exhibiting a
    deadly weapon in a threatening manner (id., § 417).
    9
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    elementary school Susana and Vicente attended.               The
    prosecution played a videotape of Alex at the police station
    showing the moment he learned Susana and Vicente had been
    murdered. The prosecution also presented a video montage of
    photographs of the victims in life and their shared gravesite.
    2. Defense Evidence
    Defendant testified on her own behalf, claiming she had
    been framed by police in general and Officer Blane Dillon in
    particular, whom she accused of having lied about the timeline
    of events and planting the incriminating evidence in her car. In
    her view, the expert had testified the hairs found on Deidra
    could have belonged to anyone. She denied being mentally ill.
    Defendant maintained her innocence of the charges and wanted
    to be sentenced to life without the possibility of parole because
    she had been framed.
    The defense also presented testimony from defendant’s
    former neighbor David Tijerina, niece Brenda Davalos, and
    sisters Martha Gudino and Maria Perez and their mother,
    Arcelia Zamudio. The evidence briefly sketched defendant’s
    family background, portrayed her as a loving mother, and
    related a change in her attitude and behavior in the months
    preceding the murders. Defendant’s family members asked for
    mercy.
    II. COMPETENCY PROCEEDINGS
    A. Factual and Procedural Background
    Before trial, the trial court declared a doubt as to
    defendant’s competence to stand trial and suspended the
    criminal proceedings under Penal Code section 1368 for a
    competency determination. The question was submitted to a
    10
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    jury. At the competency trial, defense experts — psychologists
    Michael Perrotti and Michael Kania and psychiatrist Mark
    Mills — testified that defendant was not competent to stand
    trial. Court-appointed experts — psychiatrist Jose Moral and
    psychologist Craig Rath — testified that she was competent.
    The jury found defendant competent to stand trial.
    1. Defense Evidence
    a. Psychologist Michael Perrotti
    Psychologist Michael Perrotti, Ph.D., spent 10 hours
    administering psychological tests and evaluating defendant in
    March and July 1995.
    Defendant related to Dr. Perrotti that she had a ninth
    grade education and had been physically abused by her
    husband. Regarding her current circumstances, defendant
    reported that “everyone was against her,” jail deputies
    conspired against her, she was being poisoned by a gas leak in
    her jail cell, she was hearing voices and acting aggressively to
    the point that she had to be handcuffed, and the medical staff at
    the jail was conducting experiments on her for research
    purposes. Defendant appeared depressed and confused. Her
    thoughts were disorganized and her speech pressured. She
    suffered from significant impairment of memory and
    concentration caused by a mental disorder, and Dr. Perrotti
    believed there was “a possibility of a neuro-psychological
    problem.” Dr. Perrotti did not perform neuropsychological
    testing because defendant would not cooperate.
    Dr. Perrotti opined defendant did not understand the legal
    system and had no insight into her lack of understanding.
    Everything with defendant was “clouded with suspicion,
    distrust, and [beliefs that] people are acting against her,” all of
    11
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    which hindered her ability to work with her attorney or any
    attorney. Defendant was aware of the murder charges against
    her but denied knowing who the victims were. She wanted to go
    to court so she could be released and return home.
    Dr. Perrotti diagnosed defendant as a paranoid
    schizophrenic. He did not include this diagnosis in his written
    report because he believed a description of defendant’s behavior
    and her “problems” was easier to understand than a diagnostic
    label, and had not used the label “paranoid schizophrenic” with
    regard to defendant except with trial counsel. Over the course
    of Dr. Perrotti’s evaluation of defendant, trial counsel would
    occasionally ask him, “Do you think [defendant’s]
    schizophrenic?” He admitted that his diagnosis of defendant as
    a paranoid schizophrenic did not necessarily mean that she was
    incompetent. Based on the test results, Dr. Perrotti found no
    signs defendant was malingering.
    b. Psychologist Michael Kania
    Psychologist Michael Kania, Ph.D., met with defendant on
    six or seven occasions before he evaluated her for competency
    during his visits on March 3 and April 17, 1995.                He
    administered the Minnesota Multiphasic Personality Inventory
    (MMPI) on December 17, 1994. Dr. Kania explained that
    although this psychological test is not relevant to the issue of
    competency, a determination of malingering can be made based
    on a comparison of the test results to the clinician’s impressions.
    Dr. Kania found no evidence defendant malingered on the
    MMPI. He acknowledged defendant’s scores had been evaluated
    by Dr. Alex Caldwell’s testing service, which produced a report
    stating her answers suggested “extensive intentional
    overstatement” and “some degree of deliberate malingering.”
    12
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    The report also included a warning to use caution in
    interpreting defendant’s test results because she did not answer
    all items.
    Based on his interviews with defendant, Dr. Kania
    diagnosed her as suffering from delusional disorder with
    paranoid delusions. For example, defendant thought her sister
    spoke a different language and had been influencing her
    children in this language. Defendant also believed gas was
    being pumped into her jail cell. He concluded she was
    incompetent to stand trial; although she understood the nature
    of the charges against her and had a basic understanding of the
    legal proceedings, she could not rationally assist counsel.
    c. Psychiatrist Mark Mills
    Psychiatrist Mark Mills, M.D., met with defendant on
    November 16, 1994, and April 27, 1995, for a total of two hours.
    He questioned whether she had been forthcoming during the
    interviews and believed she may have been “paranoid but hiding
    symptoms.” Defendant discussed her delusions with family
    members and others, but refused to talk with him about them.
    He diagnosed her as suffering from “a significant psychotic
    disorder, probably a delusional disorder.” Because her diagnosis
    rendered her unable to work rationally with any attorney, he
    believed her to be incompetent to stand trial.6
    d. Psychiatrist Herminio Academia
    On February 26, 1995, Riverside County Mental Health
    Department staff psychiatrist Herminio Academia, M.D.,
    6
    Dr. Mills explained that although he did not explicitly
    state in his report that defendant was incompetent, he did so
    impliedly.
    13
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    treated defendant at the jail for about 20 minutes. Defendant
    was complaining her cell was too hot, she was being “cooked,”
    and “gas was going to her cell.” Dr. Academia diagnosed
    defendant with a nonspecific psychotic disorder and prescribed
    Haldol to relieve her delusions and paranoia, but she refused the
    medication.
    e. Psychiatrist Austin Anthony
    On February 27, 1995, Riverside County Department of
    Mental Health staff psychiatrist Austin Anthony, M.D., treated
    defendant. She spoke in a rambling manner about the room
    being hot and about the smell of gas. She appeared friendly and
    cooperative and had good eye contact, but on occasion seemed
    confused and bewildered. She refused to take medication
    prescribed for her. On February 28, 1995, Dr. Anthony’s last
    appointment with defendant, he found her to be friendly and
    alert and no longer complaining of the gas smell.
    f. Testimony of defendant’s family members and
    Regena Acosta
    Defendant’s sisters Angela Montenegro, Martha Gudino,
    and Maria Perez described her delusions and bizarre behavior.
    For example, Montenegro testified that in July 1994, when she
    and her two children were living with defendant and her three
    children, defendant came home from church one day and took
    the tacos the children were eating, threw them in the garbage,
    and told Montenegro to move out. On several occasions during
    the next month, defendant accused Montenegro of feeding
    defendant’s children poisoned taco meat, being a witch, and
    turning into a snake and biting her (defendant’s) leg. On cross-
    examination, Montenegro testified she and defendant had
    attended the same church, and the church asked her
    14
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    (Montenegro) to quit attending services because of a
    relationship she had with a man named Roberto. Defendant
    accused Montenegro of being a prostitute. Montenegro told the
    police that defendant’s anger and name-calling might have had
    something to do with Roberto.
    Gudino visited defendant at the jail with their other sister,
    Perez, and their mother. Trial counsel was also present during
    the visit and asked Gudino to persuade defendant to sign
    medical information release authorization forms for any medical
    provider who treated defendant during her life. For about an
    hour and 45 minutes, Gudino, Perez, and their mother tried to
    persuade defendant to sign the forms. She refused and told her
    family that they were against her.
    Regena Acosta read about defendant in the newspapers
    after the murders. She was motivated to minister to defendant
    and visited her in jail four or five times between about
    November 1994 and February 1995. Acosta testified defendant
    told her she believed the jail guards were putting “stuff” in her
    food to make her sick. Defendant also told Acosta she did not
    understand what was going on at court.
    2. Prosecution Evidence
    a. Court-Appointed Psychiatrist Jose Moral
    On March 25, 1995, court-appointed psychiatrist Jose
    Moral, M.D., examined defendant at the jail. She was alert and
    oriented and understood the purpose of his visit. She knew she
    had been charged with murdering her three children. She
    demonstrated knowledge and understanding of the criminal
    legal process, including the various stages from arrest through
    trial and sentencing. Before having her children, she had been
    employed at a civil law firm as an assistant to the legal
    15
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    secretaries and worked with attorneys for about seven years.
    Defendant complained the proceedings were progressing too
    slowly. She denied having delusions or hallucinations and
    exhibited no psychotic symptoms during the interview.
    On July 26, 1995, Dr. Moral interviewed defendant a
    second time. Defendant again demonstrated knowledge of the
    legal system. Her relationship with counsel had improved by
    this time. She explained that her preoccupation with the smell
    of gas in her cell stemmed from news reports about deaths in
    Riverside caused by exposure to gas fumes. She denied having
    the psychotic symptoms reported by other psychologists and
    psychiatrists and gave Dr. Moral reasonable explanations for
    the reported symptoms. Defendant had no thought disorder.
    She was able to carry out her interview with Dr. Moral without
    difficulty and was “purposeful in her answers,” “cooperative,”
    “reasonable,” and “logical.” Dr. Moral believed defendant was
    competent to stand trial. During a break in the proceedings on
    the day he testified, Dr. Moral interacted with defendant and
    discussed competency issues with her. After this contact,
    Dr. Moral continued to believe defendant was competent to
    stand trial.
    b. Court-Appointed Psychologist Craig Rath
    Psychologist Craig Rath, Ph.D., was appointed on March
    14, 1995, to evaluate defendant’s competence to stand trial.
    Previously, on October 28, 1994, at the request of the Riverside
    District Attorney’s Office, Dr. Rath had interviewed defendant
    16
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    for about an hour after her arrest.7 He taped the interview, and
    the audiotape was played for the jury in its entirety.8
    Defendant’s demeanor during the interview was appropriate.
    She exhibited no signs of mental illness or psychosis putting her
    “out of contact with reality.” Defendant’s long-term and short-
    term memory were unimpaired. She communicated very well
    and protected information she did not want to share.
    Dr. Rath administered the MMPI to defendant. She
    completed 400 of 566 questions. Her answers showed a “saw-
    tooth profile,” which is a classic sign of malingering.
    After Dr. Rath was appointed by the court to evaluate
    defendant’s competency, he unsuccessfully attempted to
    evaluate defendant on March 24, 1995, and April 3, 1995.9
    Based on his October 28, 1994, interview with her shortly after
    the murders, Dr. Rath believed she was competent to stand trial
    because she “does not have any major mental illness [that]
    would preclude her from understanding what’s going on or
    cooperating with her attorney.”
    Although Dr. Rath had first interviewed defendant shortly
    after her arrest, at the request of the District Attorney’s office,
    he did not declare a conflict when the court appointed him on
    March 14, 1995, to render an opinion as to her competence to
    7
    Defendant had waived her right against self-incrimination
    and agreed to speak to a “doctor.”
    8
    The jury was also given a copy of the transcript of the
    interview.
    9
    On his first attempt, deputies at the jail informed Dr. Rath
    defendant had refused to be handcuffed, which was required
    when she was transported outside her cell because she “had
    been attacking people.”       When he returned to evaluate
    defendant in April, she refused to see him.
    17
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    stand trial. Dr. Rath denied he had a conflict under the Board
    of Medical Quality Assurance Ethics Committee’s standards.
    He testified he had contacted the committee and was told he had
    not acted unethically.       Regarding his initial visit with
    defendant, Dr. Rath pointed out it would have been unethical
    for him to refuse to see her, given she was potentially suicidal
    after the deaths of her three children.
    c. Jail Psychiatrist Romeo Villar
    Between October 28, 1994, and March 1, 1995, jail
    psychiatrist Romeo Villar, M.D., saw defendant several times
    while she was in custody. During his last contact with her in
    March 1995, defendant denied having hallucinations or suicidal
    ideations. Dr. Villar testified defendant had fair insight and
    judgment, and her affect was subdued.
    3. Defense Rebuttal Evidence
    Catherine Moreno, a paralegal employed by trial counsel,
    had had contact with defendant approximately 10 times by the
    time she testified at the competency trial. Moreno testified that
    defendant could not structure coherent paragraphs, although
    Moreno could not recall ever having read anything written by
    defendant. Moreno had never tried to talk with defendant about
    the facts of her case. Defendant refused Moreno’s numerous
    requests to sign forms to authorize the release of information
    and failed to provide any explanation. Moreno acknowledged
    she could have obtained the documents with a subpoena.
    Sherry Skidmore, Ph.D., a clinical and forensic
    psychologist, had served on local, state, and national
    psychological ethics committees. She reviewed the results of the
    MMPI test Dr. Rath administered to defendant. Based on those
    scores, Dr. Skidmore could not render an opinion as to whether
    18
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    or not defendant was malingering.         In her opinion, no
    psychologist would determine malingering from MMPI results
    alone. A determination of malingering depends on a number of
    objective measures, including a follow-up interview to clarify
    specific parts of the malingering assessment, such as distortion
    and over-reporting of symptoms. For a forensic psychologist to
    render an opinion regarding an individual’s competence based
    on an interview not conducted for the purpose of determining
    competence would fall below the standard of care.
    4. Surrebuttal
    On October 27, 1995, George Groth, a mental health
    clinician at the jail, saw defendant at her request. Defendant
    was anxious about her upcoming trial. Groth found defendant’s
    thinking clear and her speech understandable, and she
    exhibited no signs of mental illness. The parties stipulated this
    was the only time defendant was seen by the jail’s Forensic
    Mental Health unit between September 1, 1995, and the day her
    competency trial commenced, October 26, 1995.
    The parties also stipulated that on November 1, 1995, a
    search warrant was served in defendant’s jail cell. Two
    documents written by defendant in Spanish were confiscated
    during the search.10
    10
    Additional details concerning the two documents are
    provided in part II.B.4., post.

    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    B. Discussion
    1. Constitutionality of the Definition of Incompetence
    to Stand Trial Under Penal Code Section 1367,
    Subdivision (a), and CALJIC No. 4.10
    The due process guarantees of both the federal and state
    Constitutions forbid the trial of a criminal defendant while he
    or she is mentally incompetent. (See People v. Mickel (2016) 
    2 Cal.5th 181
    , 194–195.)        In California, the determination
    whether a criminal defendant is competent to stand trial is
    governed by Penal Code section 1367 (section 1367), which
    provides that a defendant is mentally incompetent “if, as a
    result of mental disorder or developmental disability, the
    defendant is unable to understand the nature of the criminal
    proceedings or to assist counsel in the conduct of a defense in a
    rational manner.” (§ 1367, subd. (a).) Consistent with that
    standard, the jury in this case was instructed with CALJIC
    No. 4.10 (Doubt of Present Mental Competence), which informed
    the jury that its task was to “decide whether the defendant is
    mentally competent to be tried for a criminal offense,” and went
    on to explain: “Although on some subjects her mind may be
    deranged or unsound, a person charged with a criminal offense
    is deemed mentally competent to be tried for the crime charged
    against her if, one, she is capable of understanding the nature
    and purpose of the proceedings against her; two, she
    comprehends her own status and condition in reference to such
    proceedings; and, three, she is able to assist her attorney in
    conducting her defense in a rational manner. [¶] The defendant
    is presumed to be mentally competent. The effect of this
    presumption is to place upon the defendant the burden of
    proving by a preponderance of the evidence that she is mentally
    incompetent as a result of a mental disorder.”
    20
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Defendant contends that the statutory definition of
    mental competence in section 1367 is inadequate to safeguard a
    defendant’s due process rights because it requires proof that a
    mental disorder or developmental disability rendered the
    defendant unable to understand the proceedings against him or
    her or to assist counsel with his or her defense. She also
    contends that both the statutory definition and CALJIC
    No. 4.10 are inadequate because they fail to require proof of (a)
    both a “rational” and a “factual” understanding of the criminal
    proceedings, and (b) a “present” ability to assist counsel in a
    rational manner. She contends these infirmities, separately and
    together, violated her right to substantive due process under the
    Fourteenth Amendment and require reversal of the entire
    judgment. Defendant’s contentions lack merit.
    a. Legal background
    As a matter of due process, “[a] defendant may not be put
    to trial unless he ‘ “has sufficient present ability to consult with
    his lawyer with a reasonable degree of rational understanding
    . . . [and] a rational as well as factual understanding of the
    proceedings against him.” ’ ” (Cooper v. Oklahoma (1996)
    
    517 U.S. 348
    , 354, quoting Dusky v. United States (1960)
    
    362 U.S. 402
    , 402 (per curiam) (Dusky).) A trial court’s failure
    “to employ procedures to protect against trial of an incompetent
    defendant deprives him of his due process right to a fair trial
    and requires reversal of his conviction.” (People v. Medina
    (1990) 
    51 Cal.3d 870
    , 881–882, citing Drope v. Missouri (1975)
    
    420 U.S. 162
    , 171 (Drope).) “ ‘Even when a defendant is
    competent at the commencement of his trial, a trial court must
    always be alert to circumstances suggesting a change that would
    render the accused unable to meet the standards of competence
    to stand trial.’ [Citation.] State constitutional authority is to
    21
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    the same effect. [Citation.]” (People v. Lightsey (2012) 
    54 Cal.4th 668
    , 690–691 (Lightsey).)
    “The applicable state statutes essentially parallel the
    state and federal constitutional directives.” (Lightsey, supra,
    54 Cal.4th at p. 691.) Section 1367, subdivision (a), provides in
    pertinent part: “A person cannot be tried or adjudged to
    punishment . . . while that person is mentally incompetent. A
    defendant is mentally incompetent for purposes of this chapter
    if, as a result of mental disorder or developmental disability, the
    defendant is unable to understand the nature of the criminal
    proceedings or to assist counsel in the conduct of a defense in a
    rational manner.”
    Penal Code section 1368 (section 1368) provides in
    relevant part: “(a) If, during the pendency of an action and prior
    to judgment . . . , a doubt arises in the mind of the judge as to
    the mental competence of the defendant, he or she shall state
    that doubt in the record and inquire of the attorney for the
    defendant whether, in the opinion of the attorney, the defendant
    is mentally competent. If the defendant is not represented by
    counsel, the court shall appoint counsel. At the request of the
    defendant or his or her counsel or upon its own motion, the court
    shall recess the proceedings for as long as may be reasonably
    necessary to permit counsel to confer with the defendant and to
    form an opinion as to the mental competence of the defendant at
    that point in time. [¶] (b) If counsel informs the court that he
    or she believes the defendant is or may be mentally incompetent,
    the court shall order that the question of the defendant’s mental
    competence is to be determined in a hearing which is held
    pursuant to [Penal Code] Sections 1368.1 and 1369. If counsel
    informs the court that he or she believes the defendant is
    22
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    mentally competent, the court may nevertheless order a
    hearing.”
    “[A] trial court is obligated to conduct a full competency
    hearing if substantial evidence raises a reasonable doubt that a
    criminal defendant may be incompetent. This is true even if the
    evidence creating that doubt is presented by the defense or if the
    sum of the evidence is in conflict. The failure to conduct a
    hearing despite the presence of such substantial evidence is
    reversible error.” (Lightsey, supra, 
    54 Cal.4th 691
    , citing People
    v. Welch (1999) 
    20 Cal.4th 701
    , 737–738.)
    The law presumes a person is competent to stand trial.
    (Pen. Code, § 1369, subd. (f).) “When the defendant puts his or
    her competence to stand trial in issue, the defendant bears the
    burden of proving by a preponderance of the evidence that he or
    she lacks competence.”           (People v. Mendoza (2016)
    
    62 Cal.4th 856
    , 871; see § 1369, subd. (f); Medina v. California
    (1992) 
    505 U.S. 437
    , 446 (Medina) [allocation of the burden of
    proof to a criminal defendant to prove incompetence does not
    violate procedural due process].)
    b. Penal Code section 1367’s requirement of proof
    of mental disorder or developmental disability
    Defendant contends that the definition of mental
    incompetence under section 1367, subdivision (a), fails to meet
    the constitutional standard because it requires proof of a mental
    disorder or developmental disability. She contends that United
    States Supreme Court decisions, by contrast, have defined
    competence to stand trial solely in the functional terms of a
    defendant’s ability to understand the nature of the proceedings
    against her and to assist her attorney in preparing her defense
    in a rational manner. (See Dusky, 
    supra,
     362 U.S. at p. 402;
    23
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Drope, 
    supra,
     420 U.S. at p. 171.) She contends that section
    1367’s requirement of proof of a mental disorder or
    developmental disability unconstitutionally narrows the
    definition of incompetence, thereby depriving a “subset of
    defendants”—those who are unable to understand the
    proceedings and assist counsel in a rational manner but do not
    “suffer from a recognized mental disorder or developmental
    disability”—of the right not to be tried while incompetent.
    In her briefing, defendant did not specify whether her
    claim relates to the facial validity of section 1367, subdivision
    (a), or the statute’s validity as applied to the particular
    circumstances of her case. At oral argument, however, appellate
    counsel clarified that defendant’s challenge is a facial attack.
    “ ‘ “To support a determination of facial unconstitutionality, . . .
    [challengers] cannot prevail by suggesting that in some future
    hypothetical situation constitutional problems may possibly
    arise as to the particular application of the statute.” ’ ” (Tobe v.
    City of Santa Ana (1995) 
    9 Cal.4th 1069
    , 1084.) Rather, the
    “minimum” our cases have accepted is a showing that the
    statute is invalid “in the generality or great majority of cases.”
    (San Remo Hotel v. City and County of San Francisco (2002)
    
    27 Cal.4th 643
    , 673; cf. Washington State Grange v. Washington
    State Republican Party (2008) 
    552 U.S. 442
    , 449 [noting that
    while some justices of the high court have embraced a more
    demanding standard, all justices “agree that a facial challenge
    must fail where the statute has a ‘ “plainly legitimate
    sweep” ’ ”].)
    In this case, defendant has failed to demonstrate that
    section 1367, subdivision (a), is facially invalid; indeed, she has
    failed to identify any case (including her own) in which section
    1367’s mental disorder or developmental disability requirement
    24
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    results in the violation of due process.11 Contrary to her
    argument, the due process right not to be tried while
    incompetent has long been understood in terms of the causal
    relationship between the defendant’s mental condition and his
    or her trial-related functional abilities. As the high court
    explained in Drope, the constitutional right is rooted in the
    venerable common law rule “that a person whose mental
    condition is such that he lacks the capacity to understand the
    nature and object of the proceedings against him, to consult with
    counsel, and to assist in preparing his defense may not be
    subjected to a trial.” (Drope, supra, 420 U.S. at p. 171.)
    Section 1367, like many other similar statutes in other
    jurisdictions, thus articulates a causal relationship between the
    existence of a mental disorder and functional impairments.12
    11
    When pressed at oral argument, appellate counsel posited
    a scenario in which a defendant does not understand the nature
    of the proceedings because of cultural differences, as opposed to
    a mental disorder or developmental disability. But cultural
    differences alone do not give rise to a lack of capacity to
    understand the nature of the proceedings or assist counsel in
    preparing a defense, as the Dusky standard requires.
    12
    When the statute was first enacted in 1872, section 1367
    provided: “A person cannot be tried, adjudged to punishment,
    or punished for a public offense, while he is insane.” Case law
    interpreting the provision established that, though a defendant
    may have claimed to be “deranged or unsound,” he was not
    “insane” for purposes of section 1367 unless he could not
    understand the nature and object of the proceedings against him
    and could not aid his counsel to conduct his defense in a rational
    manner. (People v. Perry (1939) 
    14 Cal.2d 387
    , 397, 399.) In
    1974, the Legislature amended the statute to codify this
    standard, substituting the term “mentally incompetent” for
    “insane.” (Assem. Com. on Criminal Justice, Ex Post Facto
    25
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    (See, e.g., 
    18 U.S.C. § 4241
    (d) [federal statute forbidding trial of
    a defendant found to be “presently suffering from a mental
    disease or defect rendering him mentally incompetent to the
    extent that he is unable to understand the nature and
    consequences of the proceedings against him or to assist
    properly in his defense”].) The statutory language reflects a
    view that, “[a]s a matter of law and logic,” incompetence to stand
    trial “must arise from a mental disorder or developmental
    disability that limits his or her ability to understand the nature
    of the proceedings and to assist counsel.” (Timothy J. v.
    Superior Court (2007) 
    150 Cal.App.4th 847
    , 860.) On this view,
    “[a] defendant who refuses to work with his lawyer out of spite
    alone is not incompetent,” for example, “even if that defendant
    has a serious mental disease or defect.” (United States v. Garza
    (9th Cir. 2014) 
    751 F.3d 1130
    , 1136.)
    The high court’s cases cast no doubt on the
    constitutionality of this approach. On the contrary, that court
    has characterized a state statute establishing procedures to
    determine whether a person “ ‘as a result of mental disease or
    defect lacks capacity to understand the proceedings against him
    or to assist in his own defense’ ” as facially “adequate to protect
    a defendant’s right not to be tried while legally incompetent.”
    (Drope, supra, 420 U.S. at p. 173.) And the court has since
    consistently referred to the incompetence inquiry under Dusky
    as one that focuses on the defendant’s mental condition and
    capacity. (See, e.g., Godinez v. Moran (1993) 
    509 U.S. 389
    , 401,
    fn. 12 (Moran); see also, e.g., Medina, 
    supra,
     505 U.S. at p. 450
    [at a competency hearing, “psychiatric evidence is brought to
    Analysis of Assem. Bill. No. 1529 (1973 Reg. Sess.) June 12,
    1973, pp. 3–6; Stats. 1974, ch. 1511, § 2, eff. Sept. 27, 1974.)
    26
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    bear on the question of the defendant’s mental condition”].)
    Defendant has offered no sound basis to conclude that this focus
    is inconsistent with due process.
    To the extent defendant means instead to argue that the
    Dusky standard does not require a specific medical diagnosis
    drawn from the current version of the Diagnostic and Statistical
    Manual of Mental Disorders, we do not disagree. But neither
    does section 1367 impose this sort of requirement. Although this
    statute requires that the defendant show that, because of a
    mental disorder or developmental disability, he or she is unable
    to understand the nature of the proceedings or to rationally
    assist in his or her own defense, it does not require that the
    defendant’s mental disorder fit neatly within the standard
    diagnostic taxonomy. We find no inconsistency with Dusky.
    c. Asserted omission of certain elements from
    Penal Code section 1367’s definition of
    competence to stand trial and CALJIC No. 4.10
    Defendant next contends that the definition of competence
    in section 1367 and in CALJIC No. 4.10 omit necessary elements
    from the standard articulated in Dusky, 
    supra,
     
    362 U.S. 402
     and
    thus fails to satisfy due process requirements. Under Dusky, a
    defendant is competent to stand trial if he or she “ ‘has sufficient
    present ability to consult with his [or her] lawyer with a
    reasonable degree of rational understanding’ ” and “ ‘has a
    rational as well as factual understanding of the proceedings
    against him [or her].’ ” (Id. at p. 402, italics added.) Defendant
    argues that section 1367 and CALJIC No. 4.10 omit the
    requirements of “a rational as well as factual” understanding of
    the proceedings and a “present” ability to rationally assist
    counsel. She contends the jury should be instructed that a
    defendant’s understanding of the proceedings “must be based on
    27
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    reason, as opposed to delusion, fantasy or some other non-reality
    based perception” and encompass the ability to comprehend
    facts. She also contends the instructions should require the jury
    to determine the defendant has a “present, already-existing
    ability,” as opposed to mere “potential capacity,” to rationally
    assist an attorney in conducting a defense.
    In response to similar arguments, “[w]e have previously
    observed that the language of section 1367, from which CALJIC
    No. 4.10 is drawn, ‘does not match, word for word, that of Dusky.
    But as the Court of Appeal noted in James H. v. Superior Court
    (1978) 
    77 Cal.App.3d 169
    , 177, “To anyone but a hairsplitting
    semanticist, the two tests are identical.” ’ ” (People v. Jablonski
    (2006) 
    37 Cal.4th 774
    , 808.) What we have said before applies
    equally in this case. The United States Supreme Court has itself
    articulated the standard for competency in terms similar to
    those in section 1367 and CALJIC No. 4.10. (Moran, 
    supra,
    509 U.S. at p. 402 [“Requiring that a criminal defendant be
    competent has a modest aim: It seeks to ensure that he has the
    capacity to understand the proceedings and to assist counsel.”].)
    Neither section 1367 nor the instruction is infirm merely
    because it fails to focus specifically on the defendant’s “rational
    and factual” understanding of the proceedings, as opposed to
    focusing on the defendant’s understanding of the proceedings
    more generally; we agree with the Attorney General that “one’s
    ability to grasp the nature of the proceedings necessarily
    encompasses one’s capacity to have a rational and factual
    understanding of the proceedings.”
    Nor is the statute or instruction flawed because it fails to
    refer to the defendant’s “present” ability to assist counsel. Both
    the statute and instruction are already phrased in the present
    tense, and the statutory scheme makes amply clear that the
    28
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    mental competence inquiry focuses on the defendant’s present
    abilities, as opposed to the possibility that the relevant abilities
    may be restored in the future. (See Pen. Code, § 1370, subd.
    (a)(1)(B).) To the extent defendant contends that the point
    should have been made even clearer to the jury, she made no
    such argument in the trial court and therefore has forfeited any
    objection she might have had to the omission of the term
    “present ability” from CALJIC No. 4.10.            (See People v.
    Covarrubias (2016) 
    1 Cal.5th 838
    , 876–877 (Covarrubias).)
    2. Exclusion of Psychologist Sherry Skidmore’s
    Rebuttal Testimony
    Defendant contends that the trial court erroneously
    excluded rebuttal testimony from defense psychologist
    Dr. Sherry Skidmore. The testimony was offered to impeach
    Dr. Rath’s testimony concerning his evaluation of defendant’s
    competence to stand trial (see Pen. Code, § 1369, subd. (d)).
    Specifically, Dr. Skidmore would have testified that:
    (1) Dr. Rath’s conclusion that defendant was competent to stand
    trial was invalid under professional standards because he did
    not conduct an evaluation for the purpose of determining
    competence, and (2) Dr. Rath had a conflict of interest because
    he was originally referred by the District Attorney to interview
    defendant on the day of her arrest and before the court
    appointed him to evaluate defendant’s competence. Defendant
    asserts that the erroneous exclusion of Dr. Skidmore’s
    testimony violated her state and federal constitutional rights to
    due process, a fair trial, confrontation, compulsory process, and
    to present evidence in support of her case (Cal. Const., art. I,
    §§ 15, 16; U.S. Const., 6th & 14th Amends.), and was
    29
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    prejudicial, requiring reversal of the entire judgment.13 The
    claim lacks merit.
    a. Factual and procedural background
    Clinical psychologist Craig Rath, Ph.D., testified for the
    prosecution that he interviewed defendant and administered
    the MMPI on October 28, 1994, the day of her arrest for the
    murders. Defendant had waived her Miranda14 rights and had
    agreed to speak to a doctor. The purpose of the interview was to
    evaluate defendant for possible suicide risk and to gather
    13
    In this claim and most others on appeal, defendant
    contends the asserted error or misconduct she raises infringed
    various of her state and federal constitutional rights to a fair
    and reliable trial. What we said in People v. Boyer (2006)
    
    38 Cal.4th 412
    , 441, footnote 17, is equally applicable here: “In
    most instances, insofar as defendant raised the issue at all in
    the trial court, [s]he failed explicitly to make some or all of the
    constitutional arguments [s]he now advances. In each instance,
    unless otherwise indicated, it appears that either (1) the
    appellate claim is of a kind (e.g., failure to instruct sua sponte;
    erroneous instruction affecting defendant’s substantial rights)
    that required no trial court action by the defendant to preserve
    it, or (2) the new arguments do not invoke facts or legal
    standards different from those the trial court itself was asked to
    apply, but merely assert that the trial court’s act or omission,
    insofar as wrong for the reasons actually presented to that court,
    had the additional legal consequence of violating the
    Constitution. To that extent, defendant’s new constitutional
    arguments are not forfeited on appeal. [Citations.] [¶] In the
    latter instance, of course, rejection, on the merits, of a claim that
    the trial court erred on the issue actually before that court
    necessarily leads to rejection of the newly applied constitutional
    ‘gloss’ as well. No separate constitutional discussion is required
    in such cases, and we therefore provide none.”

    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    information “for possible later use in court for one side or the
    other.”
    On March 14, 1995, without objection by the defense, the
    trial court appointed Dr. Rath to evaluate defendant’s
    competence to stand trial. (See Pen. Code, §§ 1368, 1369, subd.
    (a).) Defendant refused to meet with Dr. Rath after his
    appointment. Based on his October 28, 1994, interview of
    defendant and the results of the MMPI, Dr. Rath opined
    defendant was competent to stand trial and did not have “any
    major mental illness which would preclude her from
    understanding what’s going on or cooperating with her
    attorney.” Dr. Rath also opined defendant’s MMPI results
    showed a classic profile for malingering.
    On cross-examination, defense counsel attempted to
    impeach Dr. Rath by establishing that: (1) his evaluation of
    defendant on the day of her arrest, October 28, 1994, was not a
    competency evaluation under section 1368 because he did not
    interview her for that purpose; and (2) his agreement to
    interview defendant for the District Attorney shortly after her
    arrest created a potential conflict of interest he was required to
    disclose when the trial court later appointed him to conduct a
    competency evaluation.
    Dr. Rath denied there were any ethical problems with the
    services he rendered.       He also testified that defendant
    demonstrated no mental illness during the October 28 interview
    and that her behavior at that time appeared to be “all
    volitional.” He therefore considered her competent to stand trial
    and did not ask her specific questions about her knowledge and
    understanding of court proceedings. When counsel attempted
    to place Dr. Rath’s ethics in issue because he relied on
    31
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    information he gathered during the October 28 interview and
    testing, neither of which were for the purpose of evaluating
    competency, the expert explained he included the circumstances
    of his interview in his written report.
    Counsel also asked Dr. Rath whether his inability to
    interview defendant in March and April 1995, after his court
    appointment, potentially affected the reliability of his opinion
    that she was competent to stand trial. Dr. Rath testified he
    would have been able to elaborate more but thought his opinion
    would remain unchanged. Counsel then asked Dr. Rath about
    an ethical standard prohibiting a psychologist from offering
    evidence about an individual’s psychological characteristics
    when the psychologist has not had “an opportunity to conduct
    an examination of the individual adequate to the scope of the
    statements, opinions or conclusions to be issued” and requiring
    psychologists to make “clear the impact of such limitations on
    the reliability and validity” of their testimony.15 Dr. Rath
    agreed that no expert should “go beyond the scope of his
    database” and claimed he satisfied this ethical requirement by
    “outlining exactly what the database is and whatever
    limitations there might be.” Dr. Rath explained that in his
    report concerning defendant, he “clearly stated how much [he]
    had seen her and when [he] had not seen her. . . .”
    Dr. Rath agreed with counsel the American Psychological
    Association (APA) Guidelines contained in the APA’s Ethical
    Handbook governed his professional conduct. Counsel asked
    whether he was obligated to comply with the standard directing
    that “[f]orensic psychologists avoid providing professional
    15
    Counsel did not provide a citation to the ethical standard
    he purportedly was quoting.
    32
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    services to parties in a legal proceeding with whom they have
    personal or professional relationships that are inconsistent with
    the anticipated relationship.” Dr. Rath identified the quoted
    standard as having been taken from the Division 41 Guidelines
    for Forensic Psychologists, which he said had been rejected by
    the APA and the California licensing board as unclear and
    ambiguous. He denied that his having interviewed defendant
    for the District Attorney before his court appointment for the
    competency evaluation amounted to a conflict of interest.
    Dr. Rath testified that he had contacted the Board of Medical
    Quality Assurance Ethics Committee and had been told “there
    [was] no conflict.”
    Counsel then asked Dr. Rath whether he had complied
    with the APA guidelines requiring disclosure to the parties of
    those factors that “might reasonably affect the decision to
    contract with the forensic psychologist[],” including “prior and
    current personal or professional activities, obligations, and
    relationships that might produce a conflict of interest.”
    Dr. Rath repeated that there was no conflict of interest. Counsel
    asked Dr. Rath whether the APA guidelines required him to
    obtain consent from defendant or her counsel before conducting
    his October 28 interview, given that the interview was not court
    ordered. Dr. Rath explained that because defendant had no
    attorney at that time and had waived her Miranda rights, there
    was no violation of the APA guidelines.
    On recross-examination, counsel sought to further
    question Dr. Rath about his ethical obligations, and the
    prosecutor objected on grounds of scope and relevance. The trial
    court sustained the objection, stating, “We have covered this
    ethics thing completely” and “[w]e are done talking about
    ethics.”
    33
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Outside the presence of the jury and before the
    prosecution rested its case, trial counsel sought permission to
    present testimony by forensic psychologist Sherry Skidmore,
    Ph.D., to rebut Dr. Rath’s testimony concerning a psychologist’s
    ethical obligations. Specifically, Dr. Skidmore would have
    testified that:      (1) Dr. Rath’s competency evaluation was
    governed by ethical principles that he denied were applicable;
    (2) “it is unethical and scientifically invalid to reach a conclusion
    on the question of competency when [Dr. Rath] never actually
    interviewed [defendant] and performed a specific competency
    evaluation”; and (3) under professional standards for forensic
    psychologists, Dr. Rath had a conflict of interest because he
    interviewed defendant on October 28 at the request of the
    District Attorney before he was appointed by the court to
    evaluate her competency, and was required to “make certain
    disclosures.”       Counsel argued Dr. Skidmore’s proffered
    testimony was proper rebuttal because the jury had no evidence
    other than Dr. Rath’s own testimony on which to base its
    determination whether Dr. Rath acted ethically.
    The prosecutor objected on the basis the proffered
    testimony was collateral and excludable under Evidence Code
    section 352. The court sustained the objection, agreeing the
    proffered testimony was collateral and noting, “Dr. Rath is not
    on trial[,]” and “I allowed [defense counsel] to inquire into the
    ethical situation as Dr. Rath understood it, and [he] did and now
    we are done with that.” The court permitted counsel to
    introduce Dr. Skidmore’s testimony refuting Dr. Rath’s
    interpretation of defendant’s MMPI test results.
    In rebuttal, Dr. Skidmore testified she had specialized
    experience in the areas of professional ethics and on scoring and
    evaluating MMPI tests. She testified that a psychologist acts
    34
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    below the standard of care by rendering an opinion on
    competence to stand trial based on an interview conducted for a
    purpose other than determining competence. When the defense
    inquired whether a forensic psychologist could reach a valid
    conclusion if, at the time of the interview, he or she was working
    “in a dual role,” the court sustained the prosecution’s objection
    before Dr. Skidmore answered.
    b. Discussion
    In competency proceedings, each party may offer evidence
    to rebut evidence offered by the other side. (Pen. Code, § 1369,
    subd. (d).) Evidence bearing on the credibility of a witness is
    generally relevant, and therefore admissible, in such a
    proceeding. (Evid. Code, §§ 210, 350.)
    “As with all relevant evidence, however, the trial court
    retains discretion to admit or exclude evidence offered for
    impeachment.” (People v. Rodriguez (1999) 
    20 Cal.4th 1
    , 9.) The
    court “may exclude evidence if its probative value is
    substantially outweighed by the probability that its admission
    will (a) necessitate undue consumption of time or (b) create
    substantial danger of undue prejudice, of confusing the issues,
    or of misleading the jury.” (Evid. Code, § 352.) Such rulings are
    reviewed for abuse of discretion. (People v. Minifie (1996)
    
    13 Cal.4th 1055
    , 1070; see People v. Young (2005)
    
    34 Cal.4th 1149
    , 1199.)
    Although the trial court characterized Dr. Skidmore’s
    proffered testimony as “collateral,” the testimony was
    unquestionably relevant: Because professional psychologists
    and psychiatrists are permitted to render an opinion on the
    ultimate issue of the defendant’s competence, their adherence to
    or disregard of professional standards in forming those opinions
    35
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    is relevant to their credibility as experts. The question here is
    whether the trial court appropriately weighed the probative
    value of the testimony against the probability that its admission
    would necessitate undue consumption of time, under Evidence
    Code section 352. We ultimately need not answer the question,
    however, because even if we were to assume for the sake of
    argument that the trial court abused its discretion in excluding
    the evidence, any such error was clearly harmless.
    Dr. Skidmore would have testified that Dr. Rath violated
    professional ethical standards for a forensic psychologist
    because his evaluation of defendant’s competence to stand trial
    was based on an interview not designed for the purpose of
    evaluating competence to stand trial. She also would have
    testified that Dr. Rath had a conflict of interest when he was
    appointed to evaluate defendant’s competence because before
    his appointment it was the prosecution that initially engaged
    him to interview her. As defendant emphasizes, the trial court’s
    limitation on Dr. Skidmore’s testimony had the effect of
    precluding the jury from hearing from any expert, other than
    Dr. Rath himself, regarding relevant professional ethical
    standards for forensic psychologists.
    Ultimately, however, the circumstances of Dr. Rath’s
    prearrest examination and its limits on assessing competency
    were fully litigated, despite the limitation on the defense’s
    rebuttal evidence. In response to defense questioning, Dr. Rath
    himself agreed that no expert should “go beyond the scope of his
    data base.” As Dr. Rath also noted, his report had explained
    how much he had seen defendant and his failures to meet with
    her following his court appointment. Further, the jury heard
    testimony from Dr. Skidmore that (1) it is “below the standard
    of care” for a forensic psychologist to render an opinion about an
    36
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    individual’s competence to stand trial when the individual was
    not interviewed for that purpose,16 and (2) it is unethical for a
    psychologist to form an opinion about malingering based on the
    limited information provided by MMPI results.
    Despite this evidence, as well as the testimony of two
    defense experts opining that defendant was incompetent, the
    jury was unconvinced. Other evidence, including the writings
    taken from her cell, tended to show that defendant could
    communicate coherently and that she understood the nature of
    the proceedings against her. There is no reasonable probability
    that the jury would have reached a different conclusion had the
    defense been permitted to offer further rebuttal evidence to
    counter Dr. Rath’s claim that he accepted his court appointment
    without breaching any ethical rules or creating a conflict of
    interest. (People v. Watson (1956) 
    46 Cal.2d 818
    , 836 (Watson).)
    16
    On appeal, defendant for the first time suggests
    Dr. Skidmore’s testimony on this topic was incomplete because
    she “did not explain why a valid opinion about competence
    requires a specific kind of interview, did not describe the
    requirements for such a particularized interview, and did not
    explain why Dr. Rath’s investigative interview did not meet the
    professional standards for a competency interview.” Trial
    counsel’s proffer did not include these specifics, and the trial
    court was never made aware of the testimony defendant now
    asserts was omitted from counsel’s proffer. (See People v. Vines
    (2011) 
    51 Cal.4th 830
    , 868–869 [a reviewing court “may not
    reverse a judgment for the erroneous exclusion of evidence
    unless ‘[t]he substance, purpose, and relevance of the excluded
    evidence was made known to the court by the questions asked,
    an offer of proof, or by any other means.’ (Evid. Code, § 354,
    subd. (a).)”].) To the extent defendant claims the trial court
    erred by excluding the testimony, the issue is not properly before
    us. (People v. Livaditis (1992) 
    2 Cal.4th 759
    , 780.)
    37
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Assuming defendant has preserved a claim of federal
    constitutional error, and the error implicated federal
    constitutional rights, we conclude the error was harmless
    beyond a reasonable doubt. (Chapman v. California (1967)
    
    386 U.S. 18
    , 24.)
    3. Exclusion of Portions of Defense Expert Testimony
    During the defense case, the trial court excluded
    Dr. Kania’s testimony about defendant’s delusions regarding
    computers and Dr. Mills’s testimony about the Caldwell testing
    service report on the results of the MMPI that Dr. Rath
    administered to defendant on the day of her arrest. Defendant
    offered these portions of the experts’ testimony to support their
    opinions defendant was not competent to stand trial. The court
    excluded the testimony because the defense did not timely
    provide discovery of the evidence to the prosecutor. Defendant
    asserts that the court erroneously applied the criminal discovery
    statutes (Pen. Code, § 1054 et seq.) in excluding the evidence.
    She contends that the provisions of the Civil Discovery Act of
    1986 (Civil Discovery Act or Act)17 governed her competency
    proceeding, and that there was no violation of those provisions.
    Exclusion of the evidence, she asserts, was prejudicial error and
    denied her state and federal constitutional rights to due process
    17
    Effective July 1, 2005, the Civil Discovery Act of 1986
    (Code Civ. Proc., §§ 2016–2036) was repealed and reenacted
    without substantive changes by the Civil Discovery Act of 2004
    (id., § 2016.010 et seq.). (Stats. 2004, ch. 182, § 61; see also Cal.
    Law Revision Com. com. to § 2016; Lee v. Superior Court (2009)
    
    177 Cal.App.4th 1108
    , 1123, fn. 2.) Defendant refers to the
    repealed provisions of the 1986 Act because they were in effect
    at the time of her competency trial. For convenience, we, too,
    refer to the repealed provisions of the 1986 Act effective at the
    time of defendant’s competency trial.
    38
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    and a fair competency trial, to present evidence in support of her
    case, and to contest the prosecution’s case. The claim lacks
    merit.
    a. Factual and procedural background
    i. Dr. Kania
    During cross-examination, the prosecutor questioned
    Dr. Kania extensively regarding defendant’s delusions. On
    redirect examination, trial counsel asked Dr. Kania about his
    discussions with defendant regarding her delusional belief
    concerning computers. Dr. Kania said defendant had stated
    that computers were running the world and killing people, and
    that she did not know whether the people she saw were alive or
    were computers. The prosecutor objected to the line of
    questioning on the ground it was beyond the scope of cross-
    examination and it was “all new information” that had “never
    been [included] anywhere in a report or anything.” The court
    permitted trial counsel to reopen his examination on this topic,
    and the prosecutor again objected he had not been provided
    discovery. The court asked counsel whether discovery of this
    particular delusion had been disclosed to the prosecutor. When
    counsel responded that it did not appear in Dr. Kania’s report,
    the court sustained the prosecution’s objection and struck the
    portion of the expert’s testimony relating to defendant’s
    computer delusions. The court admonished the jury to disregard
    the testimony.
    ii. Dr. Mills
    During direct examination, Dr. Mills opined that
    defendant was not malingering and suffered from a psychotic
    disorder hindering her ability to work with an attorney. Trial
    counsel then asked whether he had reviewed the results of an
    39
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    MMPI administered to defendant by the prosecution’s expert,
    Dr. Rath. Outside the presence of the jury, the prosecutor
    objected to Dr. Mills’s testimony on the ground he was unaware
    that Dr. Mills had sent Dr. Rath’s raw data to the Caldwell
    testing service for evaluation; Dr. Mills’s report made no
    mention of this information or an opinion based on the test data.
    The prosecutor stated he had received no discovery on this
    particular issue.
    The court allowed trial counsel to question Dr. Mills
    outside the jury’s presence. Dr. Mills testified both he and
    Dr. Kania sent Dr. Rath’s MMPI results to Caldwell and had
    each received a report from Caldwell. Dr. Mills explained that,
    while there were slight differences between the reports he and
    Dr. Kania received, “for all practical purposes, they say the
    same thing.” Counsel explained he sought admission of the
    Caldwell report sent to Dr. Mills because Dr. Mills had relied on
    the report in reaching his opinion. Counsel also asserted the
    report sent to Dr. Mills was not “new material” because the
    prosecutor “had the copy of the report from [Dr.] Kania.”
    Finding that counsel had failed to provide discovery of
    Dr. Mills’s testimony concerning the Caldwell report, the court
    excluded the testimony.
    b. Discussion
    Defendant contends that the trial court erred in
    sustaining the prosecutor’s objections and in excluding portions
    of Dr. Kania’s and Dr. Mills’s testimony as sanctions for
    discovery violations. Because a competency proceeding under
    section 1368 is a special proceeding and not a criminal action
    (People v. Hill (1967) 
    67 Cal.2d 105
    , 114, fn. 3), she reasons, civil
    discovery rules apply rather than the criminal discovery statute.
    40
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    (See Code Civ. Proc., former § 2016, subd. (b)(1).) In support,
    she relies on Baqleh v. Superior Court (2002) 
    100 Cal.App.4th 478
    , 490–491, decided after her competency trial, which held
    that the Civil Discovery Act applies to competency hearings.
    Defendant argues that because the prosecutor did not comply
    with the civil rules for seeking discovery from her expert
    witnesses, in that he did not make a demand for the production
    “of all discoverable reports and writings” made by a designated
    expert in the course of preparing his or her opinion (Code Civ.
    Proc., former § 2034, subds. (a)(3), (g)), there was no basis for an
    order excluding the evidence for noncompliance with the Act’s
    requirements. Absent a discovery violation under the Act,
    defendant contends, the court abused its discretion in excluding
    Dr. Kania’s testimony about her computer-related delusions and
    Dr. Mills’s testimony about the Caldwell report concerning the
    MMPI test results Dr. Rath obtained.
    The Attorney General, citing People v. Anderson (2001)
    
    25 Cal.4th 543
    , 592, footnote 17, and People v. Williams (1997)
    
    16 Cal.4th 153
    , 250, argues preliminarily that defendant’s claim
    under the Act is forfeited on appeal because she did not rely on
    the prosecutor’s alleged noncompliance with the Act in opposing
    the objections at trial. Further, the Attorney General contends
    the trial court properly relied on the criminal discovery statutes
    in ruling on the prosecutor’s objection because no objection was
    made concerning their applicability and the state of the law was
    unsettled. (Cf. In re Scott (2003) 
    29 Cal.4th 783
    , 813–814
    [although the criminal discovery statute did not apply in a
    habeas corpus proceeding, the superior court judge logically
    cited the statute in crafting an order for limited discovery].) The
    Attorney General argues the court properly excluded the
    evidence under Penal Code section 1054.5, subdivision (c),
    41
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    because the defense failed to disclose the “statements of experts
    made in connection with the case” and the results of the mental
    examination as required by Penal Code section 1054.3,
    subdivision (a)(1), of the criminal discovery provisions. Finally,
    the Attorney General contends that, even assuming error,
    defendant suffered no prejudice because the excluded evidence
    was cumulative.
    We need not decide whether the Act or the criminal
    discovery statutes applied to defendant’s competency trial.
    Even assuming the court’s ruling excluding portions of
    Dr. Kania’s and Dr. Mills’s testimony constituted an abuse of
    discretion, the error was harmless under the “miscarriage of
    justice” standard for state law error under Watson, supra, 46
    Cal.2d at page 836.
    The court’s ruling precluded the jury from considering
    Dr. Kania’s testimony relating to defendant’s purported
    delusional beliefs about computers and Dr. Mills’s explanation
    of his reliance on the Caldwell analysis of Dr. Rath’s MMPI test
    results. Defendant offered the evidence in support of each
    expert’s opinion that defendant was incompetent to stand trial.
    The evidence was, however, cumulative of other testimony
    concerning defendant’s delusions. Dr. Kania himself testified
    the primary symptom of defendant’s psychotic disorder was her
    delusions. According to Dr. Kania, during his interviews with
    defendant, she expressed delusional beliefs that her sister was
    speaking a different language and influencing defendant’s
    children in this language, that gas was being pumped into her
    cell, and that people were trying to physically harm her and kill
    her with the gas.

    Dr. Perrotti similarly testified defendant had expressed
    delusional beliefs that she was being made the subject of a
    medical experiment, that people wanted to harm her, and that
    there was gas in her cell. In addition, Regena Acosta, who
    befriended defendant in jail, testified that defendant believed
    staff at the jail cafeteria put “stuff” in her food to make her sick.
    Defendant’s family members also testified about her delusions,
    including, for example, her belief that her sister Angela
    Montenegro fed defendant’s children poisoned meat and that
    Montenegro was a witch.
    Defendant argues, however, that Dr. Perrotti’s testimony
    concerning defendant’s delusion about gas being pumped into
    her cell was not as persuasive as, and “did not compensate” for
    the exclusion of, Dr. Kania’s testimony because Dr. Perrotti
    observed the delusion only once. She also asserts that the other
    evidence concerning her delusions came primarily from family
    members “whose impartiality the prosecutor called into
    question” and thus would not have been as persuasive as
    Dr. Kania’s account of her computer delusion. The jury,
    however, heard ample evidence of defendant’s delusional beliefs
    from a variety of sources. We see no reasonable probability that
    exclusion of Dr. Kania’s testimony about defendant’s particular
    delusional beliefs regarding computers affected the outcome of
    the proceedings. Defendant also fails to show that exclusion of
    the evidence, even if erroneous under state law, rendered her
    competency proceeding fundamentally unfair or otherwise
    violated her due process rights.
    Regarding the exclusion of Dr. Mills’s testimony, trial
    counsel represented that the expert’s testimony would be
    essentially the same as Dr. Kania’s on this point because each
    expert had submitted the results of Dr. Rath’s MMPI to
    43
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Caldwell for evaluation and each had received similar reports
    from the testing service. During the hearing on the prosecutor’s
    objection, Dr. Mills testified that the reports he and Dr. Kania
    received from Caldwell “for all practical purposes, . . . say the
    same thing.” At trial, Dr. Kania compared the Caldwell
    interpretations of the results of the MMPI tests he and Dr. Rath
    administered separately to defendant.18            Under these
    circumstances, testimony by Dr. Mills similar to Dr. Kania’s
    testimony on the same subject would have added little, if
    anything, to the weight of the evidence of incompetence.
    Defendant therefore was not prejudiced by exclusion of
    Dr. Mills’s testimony concerning the Caldwell report (Watson,
    supra, 46 Cal.2d at p. 836) and she does not otherwise show that
    exclusion of the evidence resulted in a fundamentally unfair
    competency proceeding or violated her right to due process.
    4. Admission of Defendant’s Jailhouse Writings
    Defendant contends that the trial court abused its
    discretion by admitting certain jailhouse writings in the
    prosecution’s surrebuttal case. The prosecution introduced the
    writings, which had been seized during a search of defendant’s
    jail cell the previous week, to refute defense investigator
    Catherine Moreno’s rebuttal testimony that defendant could not
    communicate coherently. Defendant argues that the writings
    were improper surrebuttal because: (1) her inability to converse
    coherently was at issue throughout the defense case-in-chief,
    18
    Among other things, Dr. Kania testified defendant’s
    MMPI results on the test he administered did not indicate
    malingering, but he acknowledged that the Caldwell report
    indicated that the results obtained by Dr. Rath suggested
    otherwise.
    44
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    meaning the prosecution should have offered the writings
    during its case-in-chief; and (2) the prosecutor had indicated he
    would not introduce the writings. Defendant contends that
    admission of the writings deprived her of her state and federal
    constitutional rights to due process and a fair competency trial.
    We reject the argument.
    a. Procedural background
    During defendant’s rebuttal, defense paralegal Catherine
    Moreno testified that she had visited with defendant about 10
    times during the previous year in an effort to get her to
    cooperate with the defense team. Moreno had four or five
    conversations with defendant about witnesses in her case and
    found her to be unhelpful, incoherent, and unable to stay on
    topic.19 On cross-examination, Moreno testified she had never
    read any of defendant’s writings.
    Later the same day, and outside the presence of the jury,
    the prosecutor informed the court that defendant’s jail cell had
    been searched the previous week and writings had been seized,
    copies of which had been provided to counsel. The prosecutor
    stated: “I have been debating back and forth, and I am still not
    convinced this second, but I think I would like to introduce the
    writings that we found in her cell to the jury. [¶] The only
    hesitancy I have is, the majority of it is in Spanish, and I don’t
    know how the Court would feel about them getting a document
    that somebody’s going to need to interpret.”
    19
    Trial counsel asked Moreno, “Have [your conversations
    with defendant] been coherent on the part of [defendant]?” and
    “have you observed whether or not [defendant]’s able to
    structure coherent paragraphs?”
    45
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    The court responded: “[W]hen . . . there is something
    written in a different language, it’s translated, and then the
    translated version is what is utilized[.]” The court expressed its
    reluctance “to send a document in Spanish into a jury. There
    may be some people who are fluent in Spanish, there may be
    some partially fluent. You don’t want to do that because you
    don’t know what is going to be the result.” The prosecutor
    responded, “All right. That’s fine. I will pass.” The court said,
    “All right. Let’s bring our jurors in. I propose at this point we
    will just end for the day and start the arguments on Monday.”
    Trial was adjourned until Monday, November 13, 1995.
    On that date, the last day of the competency trial, the prosecutor
    revisited the issue of the writings seized from defendant’s jail
    cell. He represented that the writings had been translated over
    the weekend by a certified interpreter, and he offered the
    translations, copies of which had been provided to counsel, to
    demonstrate defendant’s ability to write and form paragraphs
    and sentences. The court described one document as “three
    pages of translation attached to a number of pages that are in
    Spanish. The English portion here . . . [is] labeled, ‘Another 48-
    Hour Appointment With Death,’ and, just perusing this in
    general, it appears to be a story, and it appears to be a story that
    closely parallels [defendant’s].” The court described the second
    document as a one-page handwritten document in Spanish, the
    English translation of which comprised defendant’s “thoughts
    and/or prayers on behalf of the defendant dealing with this
    case.”
    Trial counsel objected to admission of the writings on the
    grounds the evidence should have been presented in the
    prosecution’s case-in-chief and because the prosecutor had
    indicated in the prior proceeding he would not offer the evidence.
    46
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    The court ruled: “[W]e did not close [as] to evidence. I did
    indicate we were going to leave it open for a ruling on People’s
    10 [jail records].     During the trial the seizure of this
    documentation was brought up. [The prosecutor] mentioned
    last week it was in Spanish. I mentioned to him last week, ‘How
    do you intend to introduce it, it is written in some Spanish, we
    can’t have the jurors translate it, we will have to have a
    translator translate the information.’ He did not indicate,
    necessarily, he intended to introduce it, it was considered, it was
    considered for purposes of introduction as evidence. [¶] I clearly
    remember that because I remember [thinking], ‘Isn’t that
    interesting, how are we going to go ahead with documents in
    Spanish when, obviously, they haven’t been translated?’ So, you
    are not going to be successful with an objection on those bases.”
    When the court asked trial counsel whether he had any
    objection to the contents of the writings, counsel repeated that
    at the previous proceeding, the prosecutor had indicated he
    would not offer the writings. The court stated: “I agree with
    you, the last thing we had was [People’s Exhibit] 10; however,
    we did not close [as] to evidence. It is not a surprise, we did
    discuss the information. I indicated I am not going to keep it
    out on that basis.” The court granted trial counsel 15 minutes
    to review the pages and object to their content. Trial counsel
    stated he wanted to consult with his experts “to see what, if any,
    change this would make in their diagnosis [sic].” The following
    colloquy then occurred:
    “THE COURT: Wait a minute. [¶] The way the trial
    proceeds, you go first, he goes next, you rebut, he rebuts. We
    are at his rebuttal. Do you have some authority that says you
    get a second rebuttal?
    47
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    “[TRIAL COUNSEL]: Well, I think in this instance, yes;
    not case authority, but this goes well beyond simply being
    rebuttal, this is much more in the nature of a case in chief. It
    isn’t something that occurred over the weekend.
    “THE COURT: You offered the testimony of Ms. Moreno
    from your office, who testified on rebuttal that your client could
    not form paragraphs, that she couldn’t put thoughts together
    and hold them together. Just perusing this, it clearly seems to
    rebut that presentation by you. [¶] Now, if you don’t have any
    authority for a second rebuttal, that ends the issue here on that
    basis.”
    When trial counsel did not provide additional authorities,
    the court indicated that it would recess to give counsel an
    opportunity to read the translated writings and make any
    further objections. After the recess, the court confirmed counsel
    had read the writings and asked if he had anything further.
    Counsel responded, “I have nothing additional.” The parties
    stipulated that the writings were confiscated during a search of
    defendant’s jail cell, and the court admitted the writings and
    translations.
    b. Discussion
    Penal Code section 1369 specifies the order of proof in a
    competency trial. First, defense counsel offers evidence in
    support of the allegation of mental incompetence (id., subd.
    (b)(1)); next, the prosecution presents its evidence on the issue
    of the defendant’s present mental competence (id., subd. (c));
    finally, “[e]ach party may offer rebutting testimony, unless the
    court, for good reason in furtherance of justice, also permits
    other evidence in support of the original contention” (id., subd.
    (d)). Beyond these specifications, the order of proof is generally
    48
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    within the court’s discretion. (Evid. Code, § 320.) We review a
    trial court’s ruling as to the order of proof for abuse of discretion.
    (See People v. Tafoya (2007) 
    42 Cal.4th 147
    , 175.)
    Defendant argues that evidence of her writings was not
    admissible as surrebuttal evidence because it should have been
    introduced during the prosecution’s case-in-chief, given that it
    was relevant to the prosecution’s case and already in its
    possession.20 We disagree.
    During the defense case-in-chief, several witnesses,
    including Dr. Perrotti, jail nurse Terrill, and Dr. Mills testified
    that at times defendant did not express herself coherently.
    During its case-in-chief, the prosecution had introduced
    evidence to the opposite effect, including, for example,
    Dr. Moral’s testimony that defendant could effectively
    communicate about her family, medical, and mental health
    history and “keep in touch with [him] verbally, talking back and
    forth, without difficulty.”      In rebuttal, to counter the
    prosecution’s evidence that defendant could communicate
    20
    Defendant also argues that “the prosecutor did not
    establish that the writings seized from [defendant]’s cell
    reflected her present ability to communicate coherently” because
    “[t]he documents were undated and could have been written at
    any time during the year between [her] arrest and their
    admission at trial.” At trial, however, defendant did not object
    to the admissibility of the evidence on this ground, thereby
    forfeiting this objection. In any event, the writings were
    relevant to show defendant’s ability to communicate during the
    period before trial, as to which defense paralegal Moreno had
    also testified. Defendant’s concern that the writings may not
    have been made during or immediately before trial goes to the
    weight of the evidence, not its admissibility.
    49
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    effectively and without difficulty, defense paralegal Moreno
    testified that defendant could not converse or structure
    paragraphs coherently. The prosecutor offered defendant’s
    writings in surrebuttal to refute Moreno’s rebuttal testimony.
    This was not improper. (Pen. Code, § 1369, subd. (d).)
    Defendant argues that the prosecution should have
    offered the writings in its case-in-chief because this issue was
    material to its case and already in its possession. But the same
    is true of defense witness Moreno’s rebuttal testimony that
    defendant could not communicate coherently; that testimony
    was likewise material to defendant’s case-in-chief and already
    in her possession, but not offered until after the defense and
    prosecution had each presented its case-in-chief. Under the
    circumstances, the trial court did not abuse its discretion in
    permitting the prosecution to rebut Moreno’s testimony with
    defendant’s writings.
    Further, the record does not support defendant’s
    contention that admission of the writings at the end of trial
    improperly allowed the prosecution to place undue emphasis on
    them. The writings were addressed only briefly during the
    parties’ closing arguments. The prosecutor asked jurors to
    consider all the evidence in deciding whether defendant was
    competent, telling them, among other things: “[t]here is some
    evidence you have not seen . . . the notes we had translated from
    her jail cell, took [sic] about two weeks ago,” which they should
    “[r]ead . . . [and] make [your] own decisions as to how well she
    can think or not think, the cleverness, the detail, the subtleties.”
    The prosecutor also argued that the writings demonstrated
    defendant understood the nature of the legal proceedings
    against her. Defense counsel countered that jurors should
    accord the writings little weight because they were not
    50
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    introduced earlier or given to the doctors who interviewed
    defendant. Nothing in the record suggests that the prosecution
    placed undue emphasis on the late-introduced writings.
    Finally, contrary to defendant’s assertion, the trial court’s
    ruling did not allow the prosecutor to “sandbag” the defense.
    The prosecution’s argument that the writings showed defendant
    was able to communicate coherently in writing did not inject an
    entirely new subject into the trial at the last moment. Defense
    paralegal Moreno’s rebuttal testimony that defendant could not
    communicate coherently related to events in the previous year.
    Further, the writings were not available until about a week
    before the prosecutor first indicated he might want to introduce
    them. The trial court found there was no surprise in the
    prosecution’s request to admit the writings because “we did
    discuss the information.” The record supports this finding.
    Trial counsel was on notice on November 9, 1995, that the
    prosecutor might introduce the writings but that nothing
    further would occur until they were translated.
    Defendant makes much of the prosecutor’s “I will pass”
    comment, arguing it revealed an intention to forgo admission of
    the writings.     The trial court evidently understood the
    prosecutor’s comment differently. When trial counsel objected
    on the same ground to the prosecutor’s efforts to introduce the
    writings on Monday, November 13, the court recalled that the
    prosecutor had been undecided; the court had mentally noted
    the documents had not been translated, as would be necessary
    before they could be introduced. Even assuming the court’s
    recollection of the November 9 discussion was inaccurate,
    counsel did nothing to correct the error. For these reasons, the
    court’s finding that the prosecutor’s request to introduce the
    exhibits was not a surprise was supported by substantial
    51
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    evidence. The court’s granting the prosecutor’s renewed request
    to admit the writings on the following court day was not
    fundamentally unfair.
    5. Asserted Bias in Evidentiary Rulings at the
    Competency Hearing
    Defendant contends that the trial court’s evidentiary
    rulings discussed above (pt. II.B.2.–.4., ante) demonstrated bias
    against her and in favor of the prosecution and violated her state
    and federal constitutional rights to due process. We reject the
    argument.
    Defendant first complains that the court excluded portions
    of Dr. Kania’s and Dr. Mills’s testimony as a discovery sanction
    (pt. II.B.3., ante), but permitted the prosecution to introduce the
    writings seized from defendant’s jail cell over defense objections
    the evidence was improper rebuttal evidence and untimely
    (pt. II.B.4., ante). Second, defendant asserts that the court
    treated the defense and the prosecutor differentially when it
    excluded the rebuttal testimony of defense expert Sherry
    Skidmore regarding professional standards governing forensic
    psychologists in a competency evaluation (pt. II.B.2., ante), but
    admitted the prosecution’s surrebuttal evidence of defendant’s
    writings, despite the prosecutor’s assertedly misleading
    representation he would not use the writings (pt. II.B.4., ante).
    Defendant forfeited the claim of bias by failing to raise it
    during the competency trial.       (People v. Pearson (2013)
    
    56 Cal.4th 393
    , 447; People v. Guerra (2006) 
    37 Cal.4th 1067
    ,
    1112 (Guerra).) The claim lacks merit in any event. “ ‘[A] trial
    court’s numerous rulings against a party—even when
    erroneous—do not establish a charge of judicial bias, especially
    when they are subject to review.’ ” (People v. Fuiava (2012)
    52
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    
    53 Cal.4th 622
    , 732, quoting Guerra, at p. 1112; cf. Andrews v.
    Agricultural Labor Relations Bd. (1981) 
    28 Cal.3d 781
    , 795
    [“There is no reason to explore the heart and mind of the
    [adjudicator] when effective relief is readily available if the
    reviewing court concludes a finding is unsupported by
    substantial evidence. To hold otherwise would encourage a
    losing party to raise the specter of bias indiscriminately[.]”].)
    Defendant fails to demonstrate that the court engaged in any
    judicial misconduct or exhibited bias, “let alone misconduct or
    bias that was ‘so prejudicial that it deprived defendant of “ ‘a
    fair, as opposed to a perfect, trial.’ ” ’ ” (People v. Avila (2009)
    
    46 Cal.4th 680
    , 696.)
    6. Rejection of Proposed Instruction
    Defendant asked the court to instruct the jury that if she
    were found incompetent, she would not be released from
    custody. The proposed instruction, which was patterned after
    CALJIC No. 4.01, stated in relevant part: “A verdict of
    ‘incompetent to stand trial’ does not mean the defendant will be
    released from custody. Instead, she will remain in confinement
    at a state hospital or another public or private institution for
    treatment of the mentally disordered until the court determines
    that she had [sic] regained her competence. [¶] Moreover, if and
    when the defendant is found to be competent, the criminal
    proceeding that was pending against her will be reinstituted. A
    finding by you, the jury, that the defendant is not competent to
    stand trial does not constitute the final disposition of the
    criminal case against her. Rather it will have the effect of
    postponing that case until she is deemed to be competent to
    assist in her own defense.” The trial court refused to give the
    instruction.
    53
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    On appeal, defendant contends that the court’s refusal to
    instruct the jury on the consequences of a verdict of
    incompetence was erroneous because there was a risk that the
    jurors in her trial would assume she could be immediately
    released from custody were she found incompetent, and
    therefore might find her competent to prevent her return to the
    community. Defendant relies for her argument on People v.
    Moore (1985) 
    166 Cal.App.3d 540
    , in which the Court of Appeal
    held a defendant in a sanity trial is entitled upon request to an
    instruction advising the jury that a verdict of “not guilty by
    reason of insanity” does not mean the defendant will be released
    from custody. (Id. at p. 556.) The Moore court reasoned that
    because some jurors may be unaware of the consequences of an
    insanity verdict, the instruction is necessary to guard against
    the possibility that the jurors would find the defendant sane
    because they feared an insanity verdict would result in his
    release from custody. (Ibid.) Defendant argues that this case
    involved a similar risk that jurors unfamiliar with competency
    proceedings might have found her competent simply to prevent
    her release from custody and the indefinite abeyance of her
    criminal case. Defendant further contends that she was entitled
    to the proposed instruction under the due process clause of the
    Fourteenth Amendment. In support of the argument, defendant
    cites the high court’s decision in Simmons v. South Carolina
    (1994) 
    512 U.S. 154
    , 168–169 (plur. opn. of Blackmun, J.) and
    its progeny, holding that, where future dangerousness is at
    issue, a capital defendant has a due process right to inform the
    jury that he or she will be ineligible for parole if sentenced to life
    imprisonment.
    We have previously rejected arguments similar to
    defendant’s, and do so again here. In People v. Marks (2003)
    54
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    
    31 Cal.4th 197
    , for example, the defendant sought a similar
    instruction stating, in relevant part: “ ‘If the defendant is found
    mentally incompetent to stand trial, criminal proceedings shall
    remain suspended until such time as he becomes mentally
    competent. In the meantime, the court will order the defendant
    to be confined at a state hospital for the care and treatment of
    the mentally disordered where he will participate in a program
    designed to promote the defendant’s speedy restoration to
    mental competence.’ ” (Id. at p. 221.) We upheld the trial court’s
    refusal to give the instruction, explaining the instruction was
    flawed because it “characterized defendant’s return to
    competence and the eventual resumption of criminal
    proceedings as inevitable,” even though “there [is] no guarantee
    of a speedy recovery.” (Id. at p. 222.) We “declined to extend
    Moore beyond its original context,” i.e., sanity trials. (Ibid.)
    Similarly, in People v. Dunkle (2005) 
    36 Cal.4th 861
    (Dunkle), the defendant argued the trial court erred in failing to
    instruct the jury on its own motion regarding the consequences
    of a verdict of incompetence, also analogizing his case to Moore.
    We again “declined to apply Moore outside its original context.”
    (Id. at p. 897.) We reasoned that “[b]ecause the outcome of any
    future efforts at restoring a defendant to competency is
    uncertain at the time when the jury must make its decision on
    competency, an instruction patterned after Moore and CALJIC
    No. 4.01 is necessarily speculative.” (Ibid.)
    Here, defendant’s proposed instruction on the
    consequences of an incompetency verdict suffered from the same
    basic flaw. It speculates as to defendant’s return to competence
    and resumption of criminal proceedings, matters that are
    inherently uncertain when the jury is determining competency.
    (Cf. Jackson v. Superior Court (2017) 
    4 Cal.5th 96
    , 100–102
    55
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    [describing range of possible outcomes following a
    determination of incompetence].) The court did not err in
    refusing defendant’s proposed instruction.
    7. Cumulative Error at Competency Trial
    Defendant contends her entire death judgment should be
    reversed based on the cumulative effect of the prejudice
    resulting from all of the asserted errors in her competency trial.
    We have found no prejudicial error. Where we have assumed
    the existence of error in the exclusion of portions of the
    Skidmore, Mills, and Kania testimony, we have concluded any
    error was harmless. Considered in combination, these assumed
    errors do not establish that defendant was denied a fair
    competency proceeding.
    8. Denial of Request for a Second Competency Trial
    Defendant contends that the court erred in denying her
    request for a second competency hearing under section 1368
    based on her assertion that she was increasingly unable to
    understand and respond to the legal proceedings and to
    cooperate with trial counsel in preparing her defense. She also
    contends that the asserted error violated her state and federal
    constitutional rights to due process and a fair trial. We find no
    error.
    a. Factual and procedural background
    As discussed above, on November 13, 1995, the jury
    returned its verdict finding defendant competent to stand trial
    in her criminal proceedings. On January 3, 1996, during a
    pretrial in camera hearing held outside the presence of the
    prosecutor, the court denied defendant’s motion for substitution
    of defense counsel under People v. Marsden (1970) 
    2 Cal.3d 118
    .
    In the course of the proceeding, trial counsel declared a doubt
    56
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    about defendant’s competence and requested a second
    competency hearing under section 1368. Although counsel
    offered no new information in support of his request, the court
    suspended the criminal proceedings and appointed two
    psychiatrists to evaluate defendant’s competence.
    On January 5, 1996, during proceedings at which both
    parties were present, the court vacated its order appointing
    psychiatrists pursuant to section 1368. It explained: “I was
    somewhat taken aback by [trial counsel]’s further declaration as
    to the defendant’s competency and forgot there was no District
    Attorney present, because we had a [Marsden] hearing prior to
    that, and I appointed doctors. But on reconsideration I think we
    need to have a little further information and showing before that
    can be done again.” The court informed counsel it was relying
    on our decision in People v. Medina (1995) 
    11 Cal.4th 694
    (Medina II), for its authority to reconsider its prior order
    appointing the psychiatrists. The court set the matter for a
    hearing to determine under Medina II whether there had been
    a “substantial change of circumstances” since the jury returned
    its verdict finding defendant was competent to stand trial.
    At a hearing on January 19, 1996, trial counsel renewed
    his request for appointment of mental health experts under
    section 1368 to evaluate defendant’s competence to stand trial.
    Counsel explained that his motion was based solely on new
    factual developments and not a new diagnosis. During the two
    conferences he had had with defendant since the jury had found
    her competent on November 13, 1995, counsel said, she spoke in
    a “rambling fashion” about her dissatisfaction with his
    representation. Although counsel tried to discuss the nature of
    her dissatisfaction and inform her of her options, she appeared
    to not understand his explanations. Counsel asserted that
    57
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    defendant spoke no more than 10 words during the Marsden
    hearing21 and that her conduct demonstrated a “deepened
    inability” to understand and respond to the legal proceedings
    and cooperate with counsel. In addition, after counsel informed
    her the District Attorney had filed a notice of intent to seek the
    death penalty, he questioned her to determine whether she
    understood the impact of the decision; she responded “with a
    blank stare.”
    The prosecutor argued that defendant’s incoherence and
    inability to understand the issues had been litigated at the
    competency trial, and counsel had presented no grounds for a
    new referral under section 1368. Counsel acknowledged that
    the issues presented by his renewed motion were not different
    from those litigated at defendant’s first competency trial, i.e.,
    her confusion and inability to understand the legal proceedings
    and to cooperate with counsel, but he maintained defendant had
    become “more disorganized, incoherent, and uncooperative.”
    The court denied the motion, finding counsel’s showing
    insufficient to distinguish defendant’s present condition from
    her condition before the competency trial.
    b. Discussion
    “ ‘Once a defendant has been found competent to stand
    trial, a second competency hearing is required only if the
    21
    Actually, defendant spoke somewhat more than 10 words
    at the Marsden hearing. When defendant complained about
    counsel’s representation, the court asked her to give examples.
    Defendant explained, “Okay. Sometimes I asked him, like, for
    small things that he is able to do. And he just cannot do them.
    Sometimes I ask him questions, and he never has an answer for
    them, you know. And the way he has handled the case since the
    beginning, I just don’t like it. I don’t agree with it.”
    58
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    evidence discloses a substantial change of circumstances or new
    evidence is presented casting serious doubt on the validity of the
    prior finding of the defendant’s competence.’ ” (People v.
    Leonard (2007) 
    40 Cal.4th 1370
    , 1415, quoting Medina II,
    supra, 11 Cal.4th at p. 734; see also People v. Jones (1991)
    
    53 Cal.3d 1115
    , 1153.) “More is required than just bizarre
    actions or statements by the defendant to raise a doubt of
    competency” (People v. Marshall (1997) 
    15 Cal.4th 1
    , 33), or
    “counsel’s unparticularized assertion that defendant’s condition
    had deteriorated, with no explanation of how it had done so”
    (Dunkle, 
    supra,
     36 Cal.4th at p. 904).
    We conclude the court did not err in denying defendant’s
    motion for a new competency evaluation. Trial counsel offered
    only unparticularized assertions and brief descriptions of
    isolated incidents that, in his view, reflected a “deepening” of
    defendant’s inability to understand the legal proceedings and
    cooperate with counsel. Defendant’s behavior may, however,
    have simply been a display of her unwillingness to cooperate
    with counsel. (See, e.g., Medina II, supra, 11 Cal.4th at p. 735
    [defendant’s “cursing and disruptive actions displayed an
    unwillingness to assist in his defense, but did not necessarily
    bear on his competence to do so, or reflect a substantial change
    of circumstances or new evidence casting serious doubt on the
    validity of the prior finding of the defendant’s competence”].) In
    the absence of a more specific offer of proof, the trial court did
    not err in concluding that counsel had not presented evidence of
    changed circumstances or new evidence casting a serious doubt
    on the prior finding that defendant was competent to stand trial.
    59
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    III. CRIMINAL PROCEEDINGS
    A. Jury Selection Issues
    Defendant contends that the trial court committed
    reversible error when it excused for cause two prospective
    jurors, B.R. and F.P., based solely on their written questionnaire
    answers concerning their personal views on the death penalty,
    in violation of her rights under the Sixth, Eighth, and
    Fourteenth Amendments to the United States Constitution.
    (See Wainwright v. Witt (1985) 
    469 U.S. 412
    ; People v. Stewart
    (2004) 
    33 Cal.4th 425
    , 440–455 (Stewart).)            In addition,
    defendant contends that the court erroneously excused for cause
    Prospective Juror R.J. after voir dire based on his death penalty
    views. We conclude that the court erred in excusing Prospective
    Juror B.R. for cause based solely on her questionnaire
    responses.     Reversal of defendant’s penalty judgment is
    mandated under United States Supreme Court precedent.
    (Gray v. Mississippi (1987) 
    481 U.S. 648
    , 659–667 (Gray).) In
    light of this conclusion, we need not decide whether the trial
    court erred in dismissing any of the remaining prospective
    jurors based on their death penalty views.
    1. The Jury Selection Procedure and Written
    Questionnaire
    Four panels of prospective jurors were called for selection
    of the jury in this case. After each panel was sworn, the court
    made its prefatory remarks and then screened prospective
    jurors for hardship excusals, almost all of which were resolved
    by stipulations of the parties. The remaining prospective jurors
    were instructed to complete the jury questionnaire in the jury
    assembly room and to return the following Monday.
    60
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    The 32-page questionnaire contained 81 questions and
    included a section concerning the respondents’ “Opinions about
    the Death Penalty.” The introduction to this section explained
    that if the jury found defendant to be guilty and a special
    circumstance true, a penalty trial would be held; the jury would
    choose a penalty of life without the possibility of parole or death;
    and in making the penalty choice, the jury would consider
    factors in aggravation and mitigation.
    On July 6, 1998, outside the presence of the prospective
    jurors, the court informed counsel that 122 prospective jurors
    with completed questionnaires were expected to arrive that
    morning for jury selection.         The court had “identified
    approximately 29 potential jurors from the reading of the
    questionnaires, which in my mind, if their answers were
    consistent in open court with their answers in the questionnaire,
    I would in all probability excuse them for cause.” The court
    asked the parties to consider excusing the 29 prospective jurors
    by stipulation because the courtroom could seat a maximum of
    only 92 individuals. In the alternative, the court proposed
    excusing the last 30 individuals from the random list of
    prospective jurors. The court expressed hope that “[we] can
    work through the obvious individuals to stipulate for cause.”
    The court and counsel thereafter discussed the
    qualifications of the 29 prospective jurors based solely on their
    written questionnaire responses, beginning with Prospective
    Juror B.R. When the court asked the parties for a response, trial
    counsel stated, “[W]e’ll submit it. We can’t stipulate to them
    obviously, Your Honor, but we know what the Court’s concerns
    are.” The prosecutor noted that B.R. was on his list of challenges
    for cause. Without further discussion, the court ruled, “Based
    on the answers that the potential juror would not vote for death,
    61
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    and at this time [B.R.] would be excused for cause.” No other
    cause for her excusal was identified.
    Prospective Juror F.P. was another of the 29 prospective
    jurors the court identified as probably disqualified based on her
    written questionnaire responses alone. After the court and
    counsel discussed her responses, the prosecutor challenged F.P.
    for cause under Witt. The court granted the challenge.
    The court subsequently conducted voir dire of the
    remaining prospective jurors in groups of 18. Each party was
    permitted 30 minutes to ask follow-up questions.
    During the voir dire process, the court excused Prospective
    Juror R.J. for cause under Witt. The court did not permit
    counsel to attempt to rehabilitate any of the prospective jurors
    the court had determined to be disqualified as “substantially
    impaired.” The parties exercised their for-cause and peremptory
    challenges, and the jury was sworn.
    2. Discussion
    “Under decisions of the United States Supreme Court,
    prospective jurors who express personal opposition to the death
    penalty are not automatically subject to excusal for cause as
    long as ‘they state clearly that they are willing to temporarily
    set aside their own beliefs in deference to the rule of law.’
    (Lockhart v. McCree (1986) 
    476 U.S. 162
    , 176; see Witherspoon
    v. Illinois (1968) 
    391 U.S. 510
    , 522.)      To determine if a
    prospective juror is excusable for cause without compromising a
    defendant’s constitutional rights, we inquire whether the
    prospective juror’s views on the death penalty ‘would “prevent
    or substantially impair the performance” ’ of the juror’s duties
    in accordance with the court’s instructions and his or her oath.”
    (People v. Riccardi (2012) 
    54 Cal.4th 758
    , 778 (Riccardi); see
    62
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    People v. Avila (2006) 
    38 Cal.4th 491
    , 529 (Avila); Stewart,
    
    supra,
     33 Cal.4th at pp. 446–447.)
    “Before granting a challenge for cause, the ‘court must
    have sufficient information regarding the prospective juror’s
    state of mind to permit a reliable determination as to whether
    the juror’s views would “ ‘prevent or substantially impair’ ” ’
    performance as a capital juror. [Citation.] Trial courts must
    therefore make ‘a conscientious attempt to determine a
    prospective juror’s views regarding capital punishment to
    ensure that any juror excused from jury service meets the
    constitutional standard.’ ”        (People v. Leon (2015)
    
    61 Cal.4th 569
    , 592; accord, Covarrubias, supra, 1 Cal.5th at
    p. 863.)
    On appeal, we independently review a trial court’s
    dismissal of a prospective juror under Witt based solely on his or
    her written questionnaire responses. (People v. Zaragoza (2016)
    
    1 Cal.5th 21
    , 37, citing Riccardi, supra, 54 Cal.4th at p. 779.)
    “[A] prospective juror may be discharged for cause solely on the
    basis of written questionnaire responses only if it is ‘clear’ from
    those responses that the juror is unable or unwilling to
    temporarily set aside the juror’s beliefs and follow the law.
    ([Riccardi], supra, 54 Cal.4th at p. 781, fn. 11; [Avila], supra,
    38 Cal.4th at p. 531; see also People v. McKinnon (2011)
    
    52 Cal.4th 610
    , 647–648.) Where a prospective juror’s written
    responses are ambiguous with respect to the individual’s
    willingness or ability to follow the court’s instructions in a
    potential penalty phase, the record does not support a challenge
    for cause. (Stewart, at pp. 448–449.)” (Zaragoza, supra, at
    pp. 38–39; see Covarrubias, supra, 1 Cal.5th at p. 863.)
    63
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    Preliminarily, the Attorney General argues defendant
    forfeited her claim by failing to object to the dismissal of
    Prospective Juror B.R. or request voir dire. At the time of
    defendant’s trial, however, there was no requirement of a
    contemporaneous objection or statement of grounds to preserve
    a claim of Witherspoon/Witt error in the excusal of a prospective
    juror.22 (McKinnon, supra, 52 Cal.4th at p. 637.) Nor did
    counsel forfeit the issue by submitting the question to the trial
    court. (Ibid.; People v. Lynch (2010) 
    50 Cal.4th 693
    , 733.) We
    therefore proceed to the merits of defendant’s claim.
    In her questionnaire, Prospective Juror B.R. stated that
    she was a widowed 70-year-old retired payroll clerk and had
    been a resident of the city of Riverside for 42 years. B.R.
    estimated that she had worked on the questionnaire for an hour.
    Of the 81 questions contained in the questionnaire, B.R. left 36
    questions unanswered.
    In response to Question 15, Prospective Juror B.R.
    identified herself as a religious person and indicated that her
    religious beliefs would not prohibit or make it difficult for her to
    sit as a juror. The section entitled “The Charges Here” informed
    prospective jurors that defendant was charged with the murders
    of her three minor children by stabbing and with the special
    22
    In People v. McKinnon, 
    supra,
     52 Cal.4th at page 643
    (McKinnon), we overruled People v. Velasquez (1980)
    
    26 Cal.3d 425
    , “to the extent it articulates a no-forfeiture rule
    with respect to Witherspoon/Witt excusal error” and
    prospectively held that in order to preserve a claim of such error
    for appeal, counsel—or defendant if proceeding pro se—“must
    make either a timely objection, or the functional equivalent of
    an objection, such as a statement of opposition or disagreement,
    to the excusal stating specific grounds under Witherspoon/Witt.”
    64
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    circumstance of multiple murder. In response to Question 37 in
    that section, B.R. indicated by circling “yes” that she had a
    “religious or moral feeling that would make it difficult for her to
    sit in judgment of another person.” B.R. did not have any
    feelings, positive or negative, about the criminal justice system.
    The questions Prospective Juror B.R. left unanswered
    included the following: “Would you automatically reject the
    testimony of a witness who admitted that he/she had used drugs
    or alcohol?”; “What is your opinion, if any, of psychologists or
    psychiatrists who testify in criminal cases?”; “Do you have the
    opinion that any mother who kills her children must be ‘crazy’?”;
    “Do you have any feeling about the nature of the charges in this
    case that would make it difficult or impossible for you to be fair
    or impartial?”; “Would you be reluctant to serve on a jury on a
    crime involving acts of violence and where graphic photographs
    of the victim will be in evidence?”; “Do you believe the criminal
    justice system makes it too hard for the police and prosecutors
    to convict people accused of crimes?”; and “If the judge gives you
    an instruction on the law that differs from your beliefs or
    opinions, will you follow the law at [sic] the judge instructs you?”
    She did not answer questions about her ability to follow
    instructions concerning the prosecution’s burden of proof. She
    also failed to answer the following questions: “Would you
    believe or disbelieve the testimony of a law enforcement officer
    simply because he/she is a law enforcement officer?”; “Would you
    automatically believe everything an expert said merely because
    the person is called an expert?”; and “What is it about yourself
    that makes you feel you can be a fair and impartial juror?”
    In the “Trial Issues” section of the questionnaire,
    Prospective Juror B.R. answered the following questions
    “unsure” instead of “yes” or “no”: “Do you feel you can give the
    65
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    defendant and the People a fair trial?”; “Can you objectively view
    and consider graphic photos of dead children?”; “[C]ould you
    listen to your fellow jurors and receive from them the benefit of
    their thinking concerning the evidence in this case?”; “If during
    jury deliberations . . . you become convinced that you are wrong,
    could you reconsider your position?”; and “Would you change
    your position merely because the other jurors disagree with
    you?”
    Questions 68 through 73 and 76 through 78 of the
    questionnaire concerned a prospective juror’s death penalty
    views and duties as a capital juror. In response to Question 68,
    which asked respondents to describe their “general feelings
    about the death penalty,” B.R. wrote: “I wouldn’t want to make
    that decision.” In part “a” of Question 68, which asked
    prospective jurors to rank their feelings about the death penalty
    on a scale of 1 to 10, with 1 indicating “strongly against the death
    penalty” and 10 being “strongly in favor of the death penalty,”
    B.R. ranked herself a “1.”
    In part “c” of Question 68, Prospective Juror B.R. circled
    “Yes” in response to the question, “If you are against the death
    penalty, would your opinion make it difficult for you to vote for
    the death penalty in this case, regardless of what the evidence
    was?” In Part “e” of the same question, B.R. indicated that she
    had never held a different opinion about the death penalty. In
    response to Question 73, “Do you have an opinion as to whether
    you think death or life in prison is the more severe
    punishment?,” B.R. answered, “No.” B.R. left unanswered the
    remaining death penalty questions. Among them was Question
    70, which asked, in essence, whether, no matter what the
    evidence was, the prospective juror would “ALWAYS” vote for
    the death penalty (pt. (a)) or would “ALWAYS” vote for life
    66
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    without possibility of parole (pt. (b)), or would consider all of the
    evidence and decide the appropriate penalty according to the
    law (pt. (c)).
    Based on our independent review of the record,
    Prospective Juror B.R.’s written questionnaire responses, taken
    together, did not clearly demonstrate that her death penalty
    views would prevent or substantially impair her ability to serve
    as a capital juror in accordance with the trial court’s instructions
    and her juror’s oath. (McKinnon, 
    supra,
     52 Cal.4th at p. 647;
    Avila, supra, 38 Cal.4th at p. 533.) Crucially, B.R. indicated she
    “wouldn’t want” to make a decision involving the death penalty,
    not that she could not or would not make such a decision if
    instructed to do so. B.R. also stated that her strongly held views
    against the death penalty would make it difficult to vote for the
    death penalty, but again, not that she could not or would not do
    so. Our cases make clear that “mere difficulty in imposing the
    death penalty does not, per se, prevent or substantially impair
    the performance of a juror’s duties.” (Avila, supra, at p. 530.)
    “A juror might find it very difficult to vote to impose the death
    penalty, and yet such a juror’s performance still would not be
    substantially impaired under Witt, unless he or she were
    unwilling or unable to follow the trial court’s instructions by
    weighing the aggravating and mitigating circumstances of the
    case and determining whether death is the appropriate penalty
    under the law.” (Stewart, supra, 33 Cal.4th at p. 447.)
    It is possible that Prospective Juror B.R.’s views might
    have been clearly revealed by her response to Question 70,
    which sought to determine whether prospective jurors would
    “always” vote for life imprisonment versus the death penalty.
    We have previously upheld the dismissal of jurors based on their
    written responses to questions that clearly ask whether the
    67
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    “juror would automatically vote one way or the other
    irrespective of the evidence.”            (People v. Wilson (2008)
    
    44 Cal.4th 758
    , 787 (Wilson) [questionnaire asking jurors
    whether, “ ‘[n]o matter what the evidence was,’ would they
    ‘ALWAYS vote for the death penalty’ or ‘for life without
    possibility of parole.’ ”]; see 
    id.
     at pp. 788–789.) But B.R. did not
    respond to Question 70, and the remainder of her responses
    provided no sufficient basis to conclude that B.R. was “not
    willing or able to set aside . . . her personal views and follow the
    law.” (Id. at p. 787.)
    The Attorney General argues that even if counsel’s failure
    to object to B.R.’s excusal did not result in forfeiture of the claim,
    counsel’s decision to submit the matter provided support for the
    trial court’s assessment that B.R. was excusable for cause under
    Witt. The Attorney General relies on People v. Schmeck (2005)
    
    37 Cal.4th 240
    , 262 (Schmeck), in which we said trial counsel’s
    submission of the question of a prospective juror’s qualification
    to serve in a capital trial, like a failure to object, “ ‘does suggest
    counsel concurred in the assessment that the juror was
    excusable.’ ”     (Ibid., quoting People v. Cleveland (2004)
    
    32 Cal.4th 704
    , 734–735.)
    This case is distinguishable from Schmeck. In Schmeck,
    substantial evidence supported the trial court’s finding, based
    on their voir dire responses and demeanor, that the prospective
    jurors in question were disqualified under Witt. “All four
    prospective jurors indicated at various points during their voir
    dire that, in light of their views concerning the death penalty . . .
    they were unable to state that they could consider imposing the
    death penalty in this case as a reasonable possibility.”
    (Schmeck, supra, 37 Cal.4th at p. 262.) Here, by contrast, the
    court excused Prospective Juror B.R. based solely on her
    68
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    questionnaire responses, finding she “would not vote for death.”
    As explained above, however, the evidence before the court was
    insufficient to establish that B.R.’s death penalty views would
    prevent or substantially impair her performance as a capital
    juror. (McKinnon, supra, 52 Cal.4th at p. 643; Avila, supra,
    38 Cal.4th at p. 531.) Moreover, during this portion of the jury
    selection process, the court did not permit the parties to attempt
    to rehabilitate any of the prospective jurors whom it had
    identified as excusable for cause. Under the circumstances, trial
    counsel’s decision to submit B.R.’s excusal does not alter our
    conclusion that the excusal was improper.
    This case is likewise distinguishable from McKinnon, in
    which trial counsel not only submitted the matter of prospective
    jurors’ excusal for cause under Witherspoon/Witt based solely
    on their written questionnaire responses, but also declined the
    court’s offer to conduct voir dire. (McKinnon, supra, 52 Cal.4th
    at p. 650.) In McKinnon, as in Schmeck, we reasoned that
    counsel’s conduct “signaled concurrence” in the trial court’s
    ruling; this concurrence, we said, “weigh[ed] heavily, along with
    the substance of [the] questionnaire responses, in favor of a
    determination on the merits that the excusal was proper.”
    (McKinnon, at p. 650; see id. at p. 651.) In this case, as noted,
    trial counsel was not given the option of conducting voir dire.
    And more importantly, the substance of B.R.’s questionnaire
    responses—or nonresponses, as the case may be—did not clearly
    signal that B.R. held views about the death penalty that
    rendered her “unable to deliberate fairly on the issue of penalty.”
    (Id. at p. 649.) Under the circumstances, even if we were to
    assume that counsel’s submission of B.R.’s excusal indicated
    acquiescence in the court’s ruling, it would not “weigh heavily”
    in favor of a finding that the ruling was proper. The trial court
    69
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    erred in concluding B.R. was disqualified based solely on her
    written questionnaire responses; further inquiry was necessary
    to determine whether her death penalty views actually
    warranted excusal under Witherspoon/Witt.
    The Attorney General raises an alternative ground for
    affirming the excusal: that B.R. failed to obey her juror oath and
    respond to all the questions in the questionnaire. But even
    assuming that we may affirm B.R.’s dismissal on a ground
    entirely different from the ground the trial court cited, we reject
    the Attorney General’s argument. The clerk administered the
    following oath to each panel of prospective jurors: “You and each
    of you do understand and agree that you will accurately and
    truthfully answer under penalty of perjury all questions
    propounded to you concerning your qualifications and
    competency to serve as a trial juror in the matter now pending
    before this Court.” In addition, after each panel was sworn, the
    trial court made its prefatory remarks and advised the
    prospective jurors of the importance of the juror questionnaire.
    It stated first the use of the questionnaire would “cut down the
    jury selection in this case by a number of days.” It then informed
    the prospective jurors that “the attorneys will be reading the
    questionnaires in great depth because they will be utilizing that
    information to help them select the jury in this case.” The
    “Instructions for Juror Questionnaire,” appearing on the second
    page of the questionnaire, largely repeated the trial court’s
    advisement of the questionnaire’s dual purpose and specifically
    encouraged prospective jurors to provide complete answers.
    Critically, however, the written questionnaire instructions
    included the following additional advisement, which was not
    provided orally by the trial court: “If you cannot answer a
    question, please leave the response area blank. During the
    70
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    questioning, you will be given an opportunity to explain or
    expand any answers if necessary.”
    The record does not reveal why Prospective Juror B.R. did
    not answer a substantial number of the questions on her
    questionnaire. She may have had difficulty answering the
    questions and reasonably relied on the above advisement on the
    questionnaire, with the expectation that when she and the other
    prospective jurors returned to court, the judge and attorneys
    would question her and give her an opportunity to explain her
    blank responses. Absent an explanation from B.R. as to why she
    failed to complete all of the questions, we cannot conclude she
    failed to obey her oath. The unanswered questions provided a
    reason for the trial court to voir dire B.R., but not justification
    to excuse her for cause. (See, e.g., Wilson, 
    supra,
     44 Cal.4th at
    p. 789 [a trial court should personally examine a prospective
    juror when it has “reason to suspect a prospective juror is a poor
    reader or may simply have misunderstood the questionnaire”].)
    Having found error, we turn to the question of remedy.
    “The general rule is that, absent a showing of prejudice, an
    erroneous excusal of a prospective juror for cause does not
    mandate the reversal of judgment. This rule is based on the
    principle that a ‘[d]efendant has a right to jurors who are
    qualified and competent, not to any particular juror.’ [Citation.]
    But . . . under existing United States Supreme Court precedent,
    the erroneous excusal of a prospective juror for cause based on
    that person’s views concerning the death penalty automatically
    compels the reversal of the penalty phase without any inquiry
    as to whether the error actually prejudiced defendant’s penalty
    determination. (Gray, 
    supra,
     481 U.S. at pp. 659–667 (opn. of
    the court); 
    id.,
     at pp. 667–668 (plur. opn. of Blackmun, J.); id.,
    at p. 672 (conc. opn. of Powell, J.).)”         (Riccardi, supra,
    71
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    54 Cal.4th at p. 783; see People v. Woodruff (2018) 
    5 Cal.5th 697
    ,
    745.) In accordance with this precedent, we must reverse the
    penalty judgment.23
    B. Guilt Phase Issues
    1. Defendant’s Motion for Self-Representation
    Defendant argues that the trial court committed
    reversible error in denying her request for self-representation
    under Faretta v. California (1975) 
    422 U.S. 806
    . The claim is
    without merit.
    a. Factual and procedural background
    On Monday, July 20, 1998, during the morning session on
    the second day of the prosecution’s case-in-chief, the prosecutor
    played for the jury a portion of the audiotape of defendant’s
    interview with San Jacinto Police Detective Frederick
    Rodriguez conducted on the day of the homicides. Sometime
    after the morning recess, at lead defense counsel Jay
    Grossman’s request, the trial court conducted an in camera
    hearing with only Grossman and cocounsel David Macher
    present. Grossman informed the court that defendant was
    dissatisfied with counsel’s representation and that he had
    23
    Defendant also contends that the court failed to make a
    case-specific determination concerning whether group voir dire
    was practicable, in violation of Code of Civil Procedure section
    223, and failed to conduct a voir dire adequate to identify
    prospective jurors who could not be impartial. As a result,
    defendant contends, she was denied a fair and impartial jury at
    the penalty phase in violation of article I, section 16 of the state
    Constitution and the Sixth and Fourteenth Amendments to the
    federal Constitution.     Because we conclude the penalty
    judgment must be reversed due to Witherspoon/Witt error, we
    need not address this contention.
    72
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    explained her options, one of which was to request self-
    representation under Faretta v. California, supra, 
    422 U.S. 806
    (Faretta).   Grossman had mentioned the option of self-
    representation because “the things that she’s asking us to do,
    while not unethical, are simply not in her best interest.”
    Defendant told counsel that she “wanted to represent herself
    and wanted to talk with the Court.” Grossman added, “this is a
    continuing problem [that is] exacerbated every day when there’s
    more testimony.” Cocounsel Macher stated he would object to a
    Faretta motion as untimely and not in defendant’s best interest.
    The court indicated it would allow defendant to be heard on her
    request later that day. After the hearing concluded, the
    remainder of the audiotape of defendant’s police interview was
    played to the jury.
    During the lunch recess, the court held a hearing under
    Marsden and Faretta. Lead counsel Grossman informed the
    court that, while the audiotape was being played before the jury
    that morning, defendant mentioned for the first time that she
    believed the voice on the audiotape of her police interview was
    not hers. Grossman and cocounsel Macher later met with
    defendant in a holding cell. According to Grossman, defendant
    told them that the audiotape was a fraud, that the prosecution
    was trying to frame her for the murders, and that she expected
    her attorneys to call witnesses to prove the audiotape was a
    fraud.
    Grossman informed the court: “I have no such witnesses
    and there’s never been a suggestion that that is not her voice on
    the tape. And we tried to explain that to [defendant]. She then
    said that if we wouldn’t do it, basically it was her intention to do
    it by way of either testifying or managing the case on her own.”
    Grossman continued: “[W]e have no witnesses who can contest
    73
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    the validity of that tape. I don’t know who to call, no provisions
    have been made to do that because, frankly, there was never any
    expectation that this wasn’t her voice on the tape. [¶] And I
    tried to talk to [defendant] about . . . recognizing her voice. I
    know I’m not a witness, but the information that was . . . being
    conveyed in that tape is of the nature that I told her I would find
    hard to believe a jury would believe the San Jacinto Police were
    getting somebody to invent the names of the children, the ages,
    the history with her husband, things like that. [¶] [Defendant]’s
    very adamant that it’s a fraud and insists that we go forward in
    some way to prove that it’s a fraud, and . . . this is another
    instance, in her own mind, that indicates to her that counsel is
    not making an effort to try to protect her legal rights and
    advance her interests in this case.”
    Grossman explained to the court it would be “the worst
    possible thing” for the defense to present evidence that the
    prosecution framed defendant for the murders and to also argue
    “the DNA and other things have all been fabricated.” According
    to counsel, as of that morning, defendant was “adamant” that
    “she wanted to at least explore this issue with the Court, and
    again indicate her dissatisfaction to the Court.”
    Defendant told the court that she had never heard the
    audiotape of her interview with Detective Rodriguez before it
    was played for the jury. Lead counsel Grossman informed the
    court: “We have dealt with the tape issue, at least the statement
    issues, before, although I don’t recall ever playing portions of the
    tape to her in . . . jail. We did have the transcript, but it never
    was brought to my attention that this was a fabrication.”
    The court asked defendant whether she was requesting to
    represent herself, and she answered, “Yes.” The court noted
    74
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    that lead counsel Grossman had been assigned to defendant’s
    case for two years, and the prosecution was “halfway” through
    the presentation of evidence in its case-in-chief. The court also
    stated that earlier that morning, it had overheard defendant
    yelling at both her attorneys in a “very raised, angry voice” in a
    holding cell directly adjacent to the courtroom, and asked
    Grossman, “Is that a very fair characterization?” Grossman
    answered, “Generally, yes.”
    The court asked Grossman what his “take on this” was,
    and counsel said he believed defendant’s concern “is not one of
    delay[;] her concern in her own mind is presenting what she
    considers the true facts to be to this jury.” Grossman stated that
    defendant had expressed no desire for a continuance, but
    essentially insisted that he call witnesses he did not have in
    order to dispute the accuracy of the audiotape of defendant’s
    police interview. Grossman expressed frustration “that we are
    almost at total loggerheads, ‘we’ meaning [defense counsel],
    with [defendant] . . . . And there’s a widening gulf between what
    she wants and what we can ethically do and what we think is in
    her best interests in terms of possible penalty in this case.”
    Cocounsel Macher added that after working on
    defendant’s case for two years, he considered her defense
    theories “implausible,” “fantasy,” and “just not based in reality.”
    Macher stated he could not present defendant’s theories in good
    faith because her defense “would be a disaster for both guilt and
    penalty, and we can’t do it.” The following colloquy then
    occurred:
    “THE COURT: So we have a clear record, in your opinion
    the defense that she wants presented, which she would like to
    present on her own behalf, is one, in part, based upon fantasy?
    75
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    “MR. MACHER: Your honor, from what we’ve been able
    to see in two years of working on the case, I would agree that it’s
    just not based in reality.
    “THE COURT: All right. [Defendant], are you telling me
    you want to represent yourself today; is that what you’re saying?
    “[DEFENDANT]: Yes, Your Honor.
    “THE COURT: And how do you plan on doing that?
    “[DEFENDANT]: As I have already seen how Mr. Macher
    conducted the cross-examination of Officer Blane Dillon, and
    there’s questions that could have been asked direct to him in
    regards to the timing, that he made like from San Jacinto Police
    Station to the apartments. [¶] And there’s a couple questions
    that we already have reports on that we could compare his
    answers with, because those reports are dated October 27th,
    1994. They’re very accurate.
    “THE COURT: All right. And you’re telling me that you
    are—you feel that you are competent to proceed today, without
    any further delay, in representing yourself?
    “[DEFENDANT]: From what I see in the way they have
    conducted the case, yes, I think so. I think I would be.
    “THE COURT: All right. The Court is well aware of the
    admonition pursuant to Faretta and the right to self-
    representation. [¶] And Mr. Grossman, I don’t think I am even
    going to go into it that far and advise her of the consequences of
    self-representation and the detriments thereto. Obviously this
    is a death penalty case, [defendant] knows that, and she would
    not be given any special consideration. [¶] I’m not going to voir
    dire her on that because . . . in my view of the situation, her
    conduct today at this late stage is either an obstructionist tactic
    76
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    or one of delay. It’s tardy. [¶] [Defense counsel] have been on
    this case for many, many, many months, and we’re halfway
    through the prosecution’s case. And based upon the Marsden
    request that got this far, and based upon her attitude that she
    displayed to you in the holding cell today, that I overheard, as
    far as the raised voices—and again, I didn’t hear what she said,
    I just heard her yelling at you—and her demeanor and manner
    during the Marsden hearing, it’s clear to me that that request
    for self-representation is not in good faith, and I feel that it is
    one to obstruct these proceedings and it is untimely. And that
    request is . . . denied.”24
    b. Prior Marsden hearings
    On May 20, 1996, defense conflict panel attorneys Jay
    Grossman and Frank Peasley were appointed to represent
    defendant; thereafter, conflict attorney David Macher
    substituted for Frank Peasley.          Defendant made four
    unsuccessful attempts under Marsden to substitute appointed
    counsel Grossman and Macher at the in camera hearings held
    on April 2, May 4, July 14, and July 16, 1998.25
    i. April 2 hearing
    At the April 2, 1998, Marsden hearing, the trial court
    addressed defendant’s letter to the court expressing her
    24
    We presume the trial court was referring to defendant’s
    Marsden motion that it heard and denied on July 16, 1998, the court
    day immediately preceding the current Faretta hearing. We discuss
    this hearing below.
    25
    These hearings were held before two different judges: The
    Honorable Vilia G. Sherman conducted the trial proceedings
    until she recused herself on June 16, 1998. Thereafter, the
    Honorable Patrick F. Magers conducted defendant’s trial.
    77
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    concerns about the defense DNA testing and the possibility that
    samples were lost when the DNA facility that conducted the
    analyses relocated its laboratory. Based on counsel Macher’s
    representation that no DNA samples were lost during the move,
    the trial court found that defendant had a misunderstanding
    about the samples and “no grounds here for a Marsden motion.”
    When the trial court asked defendant if she had anything
    else to call to the court’s attention, defendant answered that she
    believed the contents of police reports she possessed contained
    errors. The trial court explained to defendant that she should
    discuss her concerns with her attorneys.            Lead counsel
    Grossman informed the trial court that defendant and counsel
    had differences with respect to defense strategy and trial tactics,
    including whom to subpoena as witnesses. Counsel said that he
    suspected that prior counsel had similar problems with
    defendant and that prior to trial the issue of “who is in charge of
    the trial, the attorneys or [defendant]” will have to be resolved.
    The trial court informed defendant that “[t]he law is that
    the attorneys have the last word on everything to do with tactics
    and strategy.” Defendant told the court, “I’m not dissatisfied
    with [her attorneys], and I do not have a conflict with them.”
    She added, “All I really want is on the record two or three of the
    [police] reports. That’s about it. That is what I’m asking for.”
    Because defendant did not have the reports with her at the
    hearing, the trial court agreed to talk with her about them at
    the next proceeding.
    ii. May 4 hearing
    At counsel Macher’s request, the trial court held a
    Marsden hearing to address counsel’s concern that after he and
    lead counsel Grossman met for hours with defendant, she voiced
    78
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    “substantial dissatisfaction” with counsel, which “carried over”
    to that morning’s proceedings. Macher explained that although
    he and Grossman reviewed the evidence with defendant more
    than once and explained their defense theory, defendant told
    them that she would prepare her own defense. Neither
    Grossman nor Macher believed the theory defendant wanted to
    present was “based upon any factual matters whatsoever.”
    Macher further informed the trial court that defendant said she
    would be ready to proceed “this morning.” Both Grossman and
    Macher believed that any Faretta request was untimely and
    believed defendant’s dissatisfaction related to how counsel
    planned to conduct the defense rather than a breakdown in the
    attorney-client relationship.
    Defendant said that she was “somewhat dissatisfied” with
    defense counsel because apparently none of the defense
    witnesses included those whom she suggested. When the court
    asked defendant whether she wanted new attorneys or to
    represent herself, defendant answered, “No. Well, I’m just
    explaining the reason as to why I am somewhat dissatisfied.”
    Defendant also stated that she planned to meet with current
    counsel in the upcoming week to discuss her concerns and asked,
    “[C]an I ask the Court if I can hold my decision to see if I want
    a new counsel or not until Thursday after I speak to them?”
    When the court asked for her to clarify what she was asking,
    defendant stated, “Just for four days to find out if I will remain
    with them, stay with them until the proceedings start, until the
    trial, whatever.” The court explained that it was presently
    conducting pretrial motions and that “[t]oday’s the date set for
    trial.” Macher expressed concern that defendant might not have
    understood that if she waited to bring a Faretta motion until
    after she met with counsel during the week, which would occur
    79
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    after trial commenced, that the motion would be untimely. The
    following colloquy ensued:
    “THE COURT: Well, I was about to take that up with her,
    but I’m not clear on exactly what it is she’s asking for, to keep
    you until she hires somebody else or to represent herself in trial.
    So, [defendant], do you want to act as your own attorney
    and cross-examine witnesses and conduct the trial and call
    experts and be responsible for getting witnesses here and, in
    other words, do everything that Mr. Macher and Mr. Grossman
    are doing for you now? Is that what you’re asking?
    “[DEFENDANT]: Well, from the place that I am at it’s
    pretty hard for me to bring witnesses in.
    “THE COURT: Exactly. [¶] So are you asking me to
    replace Mr. Grossman and Mr. Macher with other attorneys? Is
    that what you’re asking?
    “[DEFENDANT]: No. I was just asking for a little time,
    but if you say we already start trial today—
    “THE COURT: All right. A little time for what?
    “[DEFENDANT]: To speak to them and show them a
    couple of defense points that they could use.
    “THE COURT: Well, I think that you will be speaking to
    them a great deal during this trial, and I’m sure they’ll be
    listening to you and the things you want them to do. They may
    not necessarily agree with you, and as your expert lawyers, it’s
    up to them to decide how to conduct the case. You need to
    understand that.
    “[DEFENDANT]: Oh, okay. Okay.”
    Before the trial court made its findings, Macher added
    that he and lead counsel Grossman reviewed a list of eight
    80
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    potential witnesses whom defendant identified as “very
    important” to her defense but found none relevant to any
    potential guilty phase issues. Macher also informed the court
    that defendant’s theory “makes no legal sense and we cannot
    pursue it” and that the views he expressed would not change
    before he and Grossman next met with her. Defendant told the
    trial court that she understood all that Macher had said.
    The trial court ruled, “To the extent that this was a
    Marsden motion, which I don’t believe it was in the true essence
    of the word, the motion is denied.” The court found no
    breakdown in the attorney-client relationship, because it found
    defendant would have the same complaints with “any other
    attorneys.” Next, the trial court ruled that it “[didn’t] truly
    believe” defendant was making a Faretta motion; in the
    alternative, any Faretta motion was untimely.
    iii. July 14 hearing
    At defendant’s request, the trial court conducted a
    Marsden hearing. Defendant repeated her concerns about lost
    DNA samples, specific DNA tests, and the list of individuals she
    wanted counsel to call to testify on her behalf. Cocounsel
    Macher reported that defendant “has been consistently confused
    despite our repeated explanations regarding the purported lost
    DNA.” He explained that “DNA evidence has never been lost in
    this case either by the government or by the defense team” and
    that the defense previously litigated all DNA issues, which were
    preserved for appeal. In addition, Macher, Grossman, and the
    defense investigator met “face-to-face” with defendant for two
    hours at the beginning of May to review her list of potential
    witnesses and unanimously agreed that none of the witnesses
    would be relevant to the guilt phase defense. Having found no
    81
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    grounds for substitution of counsel, the trial court denied the
    Marsden motion.
    iv. July 16 hearing
    On the first day of the prosecution’s case-in-chief, after the
    prosecution’s second witness was excused, and out of the
    presence of the jury, lead counsel Grossman informed the trial
    court that he wanted to address a “Marsden issue.” When
    Grossman asked the prosecutor to leave (so the trial court could
    conduct a confidential Marsden hearing), defendant said she
    wanted him to stay. The trial court cleared the courtroom of
    everyone except defendant and her counsel. Grossman informed
    the trial court that during trial, defendant expressed
    dissatisfaction “with the defense efforts in this case.” Grossman
    then stated, “Apparently, part of her complaint is that she wants
    to tell [the prosecutor] that he knows she’s innocent and is
    prosecuting her improperly. I said, I didn’t think that was a
    wise thing for her to tell him because, in my opinion, I don’t
    think he believes that.”
    Defendant repeated her concerns about the DNA testing
    and specifically that her attorneys did not dispute the DNA
    testing results with their own defense expert. Macher informed
    the trial court that the DNA admissibility issues had been
    litigated before and decided by Judge Sherman and were
    preserved for appeal. Defendant then complained, “It appears
    pretty unfair that the DA has so much proof. It’s like me being
    denied the access to an expert.” Grossman then explained that
    “[defendant]’s problem is that she feels that we should have the
    laboratory that did the analysis for us come to court. [¶] The
    problem is that their analysis in many ways is the same, as
    harmful as, or more harmful as the state laboratory. And I tried
    82
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    to explain to her this morning, there’s no sense calling somebody
    that hurts us.” Grossman and Macher made a tactical decision
    to not present the defense DNA test results.
    The trial court asked defendant if she had anything
    further, and she stated, “I just don’t agree with the way they are
    conducting the whole entire case. The way they are handling
    my case.” The trial court ruled, “The Marsden request, if that’s
    a Marsden request, it will be denied.”
    c. Discussion
    Defendant contends the court erred in denying her
    midtrial request for self-representation under Faretta, 
    supra,
    422 U.S. 806
    . We find no error.
    In Faretta, 
    supra,
     
    422 U.S. 806
    , the United States
    Supreme Court held that the Sixth Amendment to the United
    States Constitution gives criminal defendants the right to
    represent themselves. Following Faretta, in People v. Windham
    (1977) 
    19 Cal.3d 121
     (Windham), this court considered
    questions concerning the timing of a defendant’s self-
    representation request. We held that “in order to invoke the
    constitutionally mandated unconditional right of self-
    representation a defendant in a criminal trial should make an
    unequivocal assertion of that right within a reasonable time
    prior to the commencement of trial.” (Id. at pp. 127–128.)
    Otherwise, “once a defendant has chosen to proceed to trial
    represented by counsel, demands by such defendant that he be
    permitted to discharge his attorney and assume the defense
    himself shall be addressed to the sound discretion of the court.”
    (Id. at p. 128; accord, e.g., People v. Bradford (1997)
    
    15 Cal.4th 1229
    , 1365 [“[A]lthough in a criminal trial a
    defendant has a federal constitutional, unconditional right of
    83
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    self-representation, in order to invoke that right, he or she must
    make an unequivocal assertion of that right within a reasonable
    time prior to the commencement of trial.”].)26
    We have held that “timeliness for purposes of Faretta is
    based not on a fixed and arbitrary point in time, but upon
    consideration of the totality of the circumstances that exist in
    the case at the time the self-representation motion is made. An
    analysis based on these considerations is in accord with the
    purpose of the timeliness requirement, which is ‘to prevent the
    defendant from misusing the motion to unjustifiably delay trial
    or obstruct the orderly administration of justice.’ ” (People v.
    Lynch, 
    supra,
     50 Cal.4th at p. 724.) In exercising its discretion
    to grant or deny an untimely self-representation request, we
    have held the trial court should consider, among other factors,
    “the quality of counsel’s representation of the defendant, the
    defendant’s prior proclivity to substitute counsel, the reasons for
    the request, the length and stage of the proceedings, and the
    disruption or delay which might reasonably be expected to
    follow the granting of such a motion.” (Windham, supra,
    19 Cal.3d at p. 128.) When a court denies an untimely request,
    26
    After defendant’s trial, the United States Supreme Court
    held in Indiana v. Edwards (2008) 
    554 U.S. 164
    , 174–178, that
    a defendant may be denied the right to self-representation if he
    or she, although competent to stand trial, suffers from a severe
    mental illness and is unable to conduct trial proceedings without
    assistance of counsel. In People v. Johnson (2012) 
    53 Cal.4th 519
    , 527–530, we adopted the Edwards standard for competence
    to represent oneself at trial. This case, however, presents no
    issue under Edwards or Johnson; neither the court nor the
    parties addressed the question of defendant’s mental condition
    in connection with her Faretta motion.
    84
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    its ruling is reviewed for abuse of discretion. (See People v.
    Valdez (2004) 
    32 Cal.4th 73
    , 103 (Valdez).)
    Defendant does not dispute that whether to grant an
    untimely Faretta motion is addressed to the trial court’s
    discretion. But she argues that the only factor the trial court
    may properly consider is the potential for delay or other
    disruption resulting from the granting of the motion. She
    argues Windham was wrong to permit courts to consider other
    factors—an error, she contends, that is traceable to a mistaken
    assumption that the self-representation right evaporates once
    trial has begun. We agree with defendant that the potential for
    delay and disruption is an important factor in the analysis, but
    we disagree that it is the only factor the court may consider. We
    see no reason why a court may not also consider, for example,
    whether the potential disruption is likely to be aggravated,
    mitigated, or justified by the surrounding circumstances,
    including the quality of counsel’s representation to that point,
    the reasons the defendant gives for the request, and the
    defendant’s proclivity for substituting counsel. (See Windham,
    supra, 19 Cal.3d at p. 128.) Defendant cites no authority, and
    we are aware of none, to suggest that these considerations are
    impermissible under Faretta.
    Here, defendant made her request on the second day of the
    prosecution’s case-in-chief and approximately two years after
    lead counsel Grossman and cocounsel Macher were appointed to
    represent her. The request was untimely under Windham. (See
    Valdez, 
    supra,
     32 Cal.4th at p. 102 [Faretta motion made
    “moments before jury selection was set to begin” was untimely];
    People v. Horton (1995) 
    11 Cal.4th 1068
    , 1110–1111 (Horton)
    [defendant’s motion for self-representation was untimely when
    made on the date scheduled for trial after numerous
    85
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    continuances]; People v. Frierson (1991) 
    53 Cal.3d 730
    , 742
    [defendant’s request for self-representation was untimely when
    made on the eve of trial, over 10 months after appointment of
    trial counsel]; People v. Burton (1989) 
    48 Cal.3d 843
    , 853
    [defendant’s Faretta request was untimely when made “after the
    case had been called for trial, both counsel had answered ready,
    and the case had been transferred to a trial department for
    pretrial motions and jury trial” and jury selection was to
    commence the next day]; cf. Avila v. Roe (9th Cir. 2002) 
    298 F.3d 750
    , 753 [a Faretta request is timely if made before jury is
    empaneled, unless it is shown to be for the purpose of delay].)
    Defendant argues that her delay in requesting self-
    representation was justified because she had not heard the
    audiotape of her interview with Detective Rodriguez until the
    prosecutor played it for the jury. She asserts that she had no
    prior opportunity to discuss its authenticity with counsel. Lead
    counsel Grossman, however, informed the trial court that he
    previously reviewed the transcript of the statements on the
    audiotape with defendant in her jail cell and that she had never
    previously complained that the audiotape was a fabrication. If
    defendant believed that any statements were falsely attributed
    to her, she had prior opportunity to inform counsel of her
    concern that the police and prosecution fabricated the
    audiotape. Defendant’s delay was not justified on this ground.
    Because defendant’s Faretta request was untimely, we
    must consider whether the court abused its discretion in
    denying the request. No abuse of discretion has been shown.
    The source of defendant’s dissatisfaction with her attorneys was
    their unwillingness to make unsupported attacks on the
    prosecution case that in their professional judgment would have
    been contrary to their client’s interests. Defendant had
    86
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    previously expressed similarly unfounded complaints about
    counsel and sought their replacement. Although defendant did
    not explicitly request a continuance if she took on her own
    defense, and asserted she “th[ought]” she was “competent” to
    take over her defense immediately, the defense she apparently
    intended to take on—attempting to show that the tape of her
    police interview had been fabricated—would by its nature
    involve delay to investigate and secure witnesses. The trial
    court reasonably concluded that defendant’s midtrial Faretta
    request was made for purposes of disruption or delay and that
    it would indeed have that effect.            Considering these
    circumstances, the court did not abuse its discretion. (See
    Valdez, 
    supra,
     32 Cal.4th at p. 103; Horton, 
    supra,
     11 Cal.4th at
    pp. 1110–1111; People v. Burton, supra, 48 Cal.3d at pp. 853–
    854; Windham, supra, 19 Cal.3d at pp. 129–130.)
    2. Jury Instructions on the Degree of Murder and on
    Motive
    Defendant contends that the trial court’s instructions to
    the jury on doubt as to the degree of murder (CALJIC No. 8.71),
    unanimity as to first or second degree murder (CALJIC
    No. 8.74), and motive (CALJIC No. 2.51) were flawed and
    diluted the prosecution’s burden of proof. CALJIC Nos. 8.71 and
    8.74, she contends, were confusing and ambiguous regarding the
    degree of murder, and CALJIC No. 2.51 permitted the jury to
    find guilt based on motive alone and also placed a burden of
    proving innocence on the defense. Defendant argues that these
    instructional errors require reversal of her death judgment.
    As an initial matter, the Attorney General contends
    defendant has forfeited these issues by failing to object to the
    challenged instructions at trial. We agree in part. In general, a
    defendant may raise for the first time on appeal instructional
    87
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    error affecting his or her substantial rights. (Pen. Code, § 1259;
    People v. Coffman and Marlow (2004) 
    34 Cal.4th 1
    , 103, fn. 34.)
    But “[a] party may not argue on appeal that an instruction
    correct in law was too general or incomplete, and thus needed
    clarification, without first requesting such clarification at trial.”
    (People v. Hillhouse (2002) 
    27 Cal.4th 469
    , 503.)              Here,
    defendant’s claim that CALJIC No. 2.51 improperly permitted
    the jury to find her guilty based on evidence of motive alone is
    forfeited because, at bottom, it is an argument that the
    instruction was incomplete. Defendant was obligated to request
    a clarifying instruction and failed to do so, thereby forfeiting her
    appellate challenge. (Guerra, supra, 37 Cal.4th at p. 1134.) Her
    other claims, asserting the instructions were incorrect, are
    reviewable despite the lack of an objection below. (People v.
    Gamache (2010) 
    48 Cal.4th 347
    , 375, fn. 13.) In any event, all
    of the claims fail on the merits.
    a. CALJIC Nos. 8.71 and 8.74
    Since defendant’s trial, we have twice addressed
    troublesome language in the 1996 revised version of CALJIC
    No. 8.71 given in this case.        (People v. Salazar (2016)
    
    63 Cal.4th 214
    , 246–248 (Salazar); People v. Moore (2011)
    
    51 Cal.4th 386
    , 410–411 (Moore).) As given here, the instruction
    told the jury, “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 the defendant the benefit of
    that doubt and return a verdict fixing the murder as of the
    88
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    second degree.”27 As we have acknowledged, the references to
    unanimity in this instruction are potentially confusing in light
    of their apparent contradiction of other instructions that
    correctly inform the jury that it must unanimously acquit the
    defendant of the greater offense before it may render a verdict
    on a lesser included offense. We have concluded, however, that
    in light of the totality of the instructions there is no reasonable
    likelihood any confusion created by CALJIC No. 8.71 could be
    detrimental to the defendant. “If anything, [this instruction]
    skewed the deliberations in [defendant’s] favor. [It] could
    reasonably be understood to tell the jurors that if they all agreed
    there was reasonable doubt as to the degree of the crime,
    because some jurors were not convinced, then defendant was
    entitled to the benefit of the doubt and a verdict of the lesser
    offense.” (Salazar, supra, 63 Cal.4th at p. 247.) We reach the
    same conclusion in this case.
    Like the defendants in Moore and Salazar, defendant also
    argues that CALJIC No. 8.71 could have misled some jurors into
    believing they were foreclosed from giving her the “benefit of the
    doubt” if other jurors were convinced beyond a reasonable doubt
    that she was guilty of first degree murder. The unconvinced
    jurors, defendant argues, would conclude from the unanimity
    language in the instruction that they could not give her the
    benefit of the doubt because not all jurors were unsure of the
    degree of the murder, and therefore the jurors with a doubt
    would be required to vote for first degree murder. This
    argument also fails. As we explained in Salazar, “No logical
    27
    The trial court did not give the jury the concluding
    bracketed portion of the pattern instruction, which read “as well
    as a verdict of not guilty of murder in the first degree.”
    89
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    reading of the instructions leads to a compelled verdict of first
    degree murder.” (Salazar, supra, 63 Cal.4th at p. 247.)
    Viewing the jury instructions as a whole, as we must
    (People v. Huggins (2006) 
    38 Cal.4th 175
    , 192), we conclude the
    jurors would have understood that they must be individually
    convinced of defendant’s guilt beyond a reasonable doubt before
    convicting her of first degree murder. (See CALJIC Nos. 8.74
    [requiring a jury to unanimously agree on the degree of murder
    before returning a murder verdict]; 17.40 [requiring a juror to
    make an individual decision and not decide a question by merely
    following the majority vote]; 17.43 [directing the jury to address
    any question during deliberation to the trial court]; and 8.30
    [instructing the jury that unpremeditated second degree murder
    was an intentional unlawful killing with malice aforethought
    “but the evidence is insufficient to prove deliberation and
    premeditation”].) Any jurors who might personally have been
    persuaded to give defendant the benefit of the doubt regarding
    the degree of murder when other jurors had concluded she was
    guilty of first degree murder would have understood that they
    could not properly vote to convict her of first degree murder
    because, in their view, the prosecution had not proven her guilt
    of that offense beyond a reasonable doubt. (See also People v.
    Musselwhite (1998) 
    17 Cal.4th 1216
    , 1262–1263 [instruction
    nearly identical to CALJIC No. 2.02, which was given in this
    case, provided adequate benefit-of-the-doubt instruction under
    People v. Dewberry (1959) 
    51 Cal.2d 548
    , 555–557]; People v.
    Friend (2009) 
    47 Cal.4th 1
    , 55 [despite the trial court’s failure to
    give CALJIC No. 8.71, in light of the giving of CALJIC Nos. 8.79
    and 17.10, among others, the jury was adequately instructed on
    the Dewberry benefit-of-the-doubt principle].) In the scenario
    defendant envisions, a jury’s reasonable understanding of the
    90
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    instructions as a whole would result in a hung jury, not a
    directed verdict for first degree murder, as she appears to argue.
    Defendant lastly contends that CALJIC No. 8.74, which
    told the jury it “must agree unanimously as to whether she is
    guilty of murder of the first degree or murder of the second
    degree” before returning a verdict, was flawed because it did not
    clarify the confusion caused by giving CALJIC No. 8.71, nor did
    it mention the requirement to find the degree of murder beyond
    a reasonable doubt.28 As a result, she argues, CALJIC No. 8.74
    diluted the prosecution’s burden of proof. We disagree. As we
    have explained, CALJIC No. 8.71 is a benefit-of-the-doubt
    instruction concerning the role of the juror’s individual
    judgment in deciding between first and second degree murder.
    (Moore, supra, 51 Cal.4th at p. 411.) CALJIC No. 8.74 properly
    instructed the jurors on returning a verdict. Specifically, the
    instruction correctly informed the jurors that if they
    unanimously found defendant guilty of murder, they had to
    unanimously agree on the degree of the murder before returning
    a verdict.
    Nothing in CALJIC No. 8.74 contradicted other
    instructions clarifying the requirement that the jurors
    determine whether the prosecution proved defendant’s guilt of
    first degree or second degree murder beyond a reasonable doubt.
    Jurors were instructed that the presumption of innocence places
    on the prosecutor “the burden of proving [defendant] guilty
    28
    CALJIC No. 8.74, as given in its entirety, provided:
    “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 her guilty of an unlawful
    killing, you must agree unanimously as to whether she is guilty
    of murder of the first degree or murder of the second degree.”
    91
    PEOPLE v. BUENROSTRO
    Opinion of the Court by Kruger, J.
    beyond a reasonable doubt” (CALJIC No. 2.90) of “the crime of
    murder” (CALJIC No. 8.10). CALJIC No. 8.70 instructed the
    jury that if it found defendant guilty of murder, it had to decide
    whether the murder was “of the first or second degree.” The
    jurors were instructed on the elements of first degree murder
    (CALJIC Nos. 8.11, 8.20) and second degree murder (CALJIC
    Nos. 8.30, 8.31). Finally, the jurors were instructed under
    CALJIC No. 2.01 (sufficiency of circumstantial evidence) that
    each fact on which an inference of guilt rests must be proved
    beyond a reasonable doubt. We presume jurors understand and
    follow the instructions they are given, including the written
    instructions. (Wilson, supra, 44 Cal.4th at p. 803.) There is no
    likelihood the jurors misinterpreted the instructions concerning
    the prosecutor’s burden of proving first degree or second degree
    murder in a manner that violated defendant’s constitutional
    rights.
    b. CALJIC No. 2.51
    Defendant contends that the trial court’s instruction on
    motive under CALJIC No. 2.5129 improperly allowed the jury to
    find her guilty based on motive alone and shifted to her the
    burden of proving an absence of motive in order to establish her
    innocence, thereby undermining the prosecution’s burden of
    proof. We have previously rejected these claims (People v. Letner
    and Tobin (2010) 
    50 Cal.4th 99
    , 191), and defendant provides no
    persuasive reason to revisit that conclusion.
    29
    CALJIC No. 2.51 states: “Motive is not an element of the
    crime charged and need not be shown. However, you may
    consider motive or lack of motive as a circumstance in this case.
    Presence of motive may tend to establish the defendant is guilty.
    Absence of motive may tend to show the defendant is not guilty.”

    3. Superfluous Multiple-Murder Special-
    Circumstance Findings
    Citing People v. Halvorsen (2007) 
    42 Cal.4th 379
    , 422,
    defendant correctly notes that two of the three multiple-murder
    special-circumstance allegations were erroneously charged and
    found true in this case. “In numerous cases involving the same
    kind of error, we have stricken the superfluous finding[s] and
    concluded the defendant suffered no prejudice. [Citations.]”
    (Ibid.) We do so again in this case.
    C. Penalty Phase Issues
    Defendant raises several claims of error at the penalty
    trial. Because we conclude the penalty judgment must be
    reversed for Witherspoon/Witt error, we do not address these
    claims. (See Riccardi, supra, 54 Cal.4th at p. 839.)
    IV. DISPOSITION
    We affirm the judgment as to guilt, vacate two of the three
    multiple-murder special-circumstance findings, reverse the
    judgment as to the sentence of death, and remand the matter
    for a new penalty determination.
