    PEOPLE v. BLOOM
    S095223
    Opinion of the Court by Kruger, J.
    After a federal court vacated his earlier conviction and
    sentence, defendant Robert Maurice Bloom was retried and
    convicted of the first degree murder of his father and the second
    degree murders of his stepmother and stepsister. The jury on
    retrial also found true a multiple-murder special-circumstance
    finding and various firearm- and weapon-use findings. (Pen.
    Code, §§ 187, subd. (a), 190.2, subd. (a)(3), 1203.06, subd. (a)(1),
    12022, subd. (b), 12022.5, subd. (a).) Bloom was sentenced to
    death. This appeal is automatic. (Id., § 1239, subd. (b).)
    We now affirm the judgment in part and reverse in part.
    At trial, defense counsel conceded Bloom’s responsibility for the
    deaths of all three victims in an effort to pursue a mental
    capacity defense to the murder charges. Bloom, however, was
    willing to accept responsibility only for the killing of his father
    and expressly objected to admitting responsibility for the deaths
    of the other two victims. In conceding responsibility for these
    victims against Bloom’s wishes, defense counsel violated
    Bloom’s Sixth Amendment right to choose the fundamental
    objectives of his defense under McCoy v. Louisiana (2018) 584
    U.S. ___ [
    138 S.Ct. 1500
    ]. The error does not affect Bloom’s
    conviction for the murder of his father or the associated firearm-
    use finding. But the error requires us to reverse the rest of the
    judgment, including the second degree murder convictions
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    relating to the other two victims, the multiple-murder special-
    circumstance finding, and ultimately the judgment of death.
    The People may retry Bloom on the relevant counts and
    associated enhancement and special circumstance allegations if
    they so choose.
    I. FACTS
    Bloom was charged with and convicted of the murders of
    his father, Robert Bloom, Sr.; his stepmother, Josephine Bloom;
    and his eight-year-old stepsister, Sandra Hughes. In an earlier
    automatic appeal, we affirmed Bloom’s conviction and death
    sentence. (People v. Bloom (1989) 
    48 Cal.3d 1194
    .) A federal
    court then granted habeas relief on the ground that Bloom’s trial
    counsel had rendered ineffective assistance in the investigation
    and presentation of mental health evidence. (Bloom v. Calderon
    (9th Cir. 1997) 
    132 F.3d 1267
    .) This case now returns to us
    following Bloom’s retrial for the murders.
    On retrial, Bloom entered alternative pleas of not guilty
    and not guilty by reason of insanity. The jury found Bloom
    guilty of the first degree murder of his father and an associated
    firearm allegation but reported that it was unable to reach
    verdicts on the remaining counts. The prosecution then
    dismissed the allegations in support of first degree murder on
    the other two murder counts, and the jury found Bloom guilty of
    second degree murder as to each count. It also found true
    associated firearm-use and weapon-use allegations and a
    multiple-murder special-circumstance allegation.
    After the jury returned a guilty verdict, the court held a
    sanity trial. The jury found Bloom sane as to the first degree
    murder but was unable to reach a verdict as to the two second
    degree murders. Defendant then withdrew his plea of not guilty
    2
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    by reason of insanity and proceeded to a penalty trial, at which
    he represented himself. The jury returned a death verdict and
    the court entered judgment accordingly.
    A. Guilt Phase Evidence
    1. Prosecution case
    In 1982, Robert Bloom, Sr., his wife, Josephine (whose
    given name was Lucille), and her eight-year-old daughter,
    Sandra Hughes (also known as Sandy), lived in a house on
    Sancola Avenue in Sun Valley. Bloom, 18 years old at the time,
    stayed at the house off and on.
    The murders occurred during the early morning on April
    22, 1982. One witness, Dave Hughes, had been asleep with his
    girlfriend in a van parked in the driveway of his parents’ house,
    which was next door to the Bloom residence. After being
    awakened by the sound of a toilet flushing in his parents’ house,
    Hughes heard two people arguing outside his van. Looking out
    the van’s rear window, he saw Bloom, Sr., on his front lawn and
    Bloom standing in the street. Bloom, Sr., was “hollering” at
    Bloom in an “angry[,] pleading” voice to “come back.” Bloom,
    Sr., then chased after Bloom, who had taken off running down
    the street. A few minutes later, Bloom, Sr., and Bloom returned
    together. The two men entered the Bloom residence.
    Hughes tried to go back to sleep but heard more arguing
    outside his van. Looking out again, he saw Bloom heading off
    in the opposite direction from the one he had previously taken,
    while Bloom, Sr., stood in his yard, again telling Bloom to come
    back. A minute or two later, Hughes heard a shot that sounded
    like a .22- or .25-caliber gun. Bloom, Sr., clutched his
    midsection, started jumping up and down and screaming, and
    ran toward his house. Bloom came running, pointing a rifle at
    3
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom, Sr. Hughes heard two more gunshots, followed by the
    sound of glass breaking. Bloom, Sr., fell onto the front porch.
    Bloom approached and pointed a rifle at his father. Hughes
    heard two more shots.
    Bloom ran into the house and Josephine began screaming.
    After two gunshots, the screaming stopped. Between 30 seconds
    and a minute later, there was another shot. Hughes got out of
    the van and entered his parents’ house to call 9-1-1, then went
    back to the van to get his girlfriend. As he came around the side
    of his parents’ house, he saw Bloom standing in the dining room
    window of the Bloom residence “messing” with his rifle. Bloom
    put down the gun and stared out the window. Hughes saw
    Bloom leave the house, put the rifle in Josephine’s car, and drive
    away. Police arrived within five minutes.
    Another witness, Moises Gameros, was living on Sancola
    Avenue across the street and a few doors up from the Bloom
    residence. Gameros woke up in the early morning hours on
    April 22 and heard someone repeatedly yelling “Robert.”
    Looking out his window, Gameros saw Bloom, Sr., and Bloom
    walking down Sancola Avenue. Bloom was holding a rifle.
    Standing outside Gameros’s living room window, Bloom, Sr.,
    said, “That’s it, I’m gonna call the cops,” and walked back toward
    his house. Bloom followed and tried to enter the house after
    him. It appeared to Gameros that Bloom, Sr., tried to grab the
    rifle from Bloom from within the house. Bloom then ran from
    the house, with Bloom, Sr., chasing him, past Gameros’s field of
    vision. Gameros heard a shot and heard Bloom, Sr., screaming.
    Bloom, Sr., turned and ran toward his house; Bloom shot him
    again. Bloom, Sr., reached the front stairs to his house and fell.
    From his vantage point, Gameros could no longer see Bloom, Sr.,
    but he saw Bloom point the rifle downward and shoot once more.
    4
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom stood in the doorway for about a minute, manipulating
    the rifle, and then entered the house. Gameros heard nothing
    further. After about 10 minutes, Bloom emerged from the house
    with the rifle, got into a car, and drove away.
    Sergeant Joseph Dvorak of the Los Angeles Police
    Department was the first to respond to the scene. He found
    Bloom, Sr., in the front doorway and Josephine in a hallway or
    bedroom. Both were dead. Sandra was found in a different
    bedroom, alive but seriously injured. After an ambulance
    arrived and took the child, Dvorak secured the crime scene.
    Sergeant Michael McKean of the Los Angeles Police Department
    arrived about 4:15 a.m. Along with two other police cars, he
    drove to the home of Bloom’s girlfriend, accompanied by a
    neighbor who knew its location. The neighbor saw Bloom
    walking westbound on Nettleton Avenue, two and a half to three
    miles from the Sancola residence, and pointed him out. Officers
    arrested him. Later that day, McKean located Josephine’s car
    parked on the street a mile and a half to two miles from where
    Bloom was arrested.
    A later autopsy determined that Bloom, Sr., had died of
    gunshot wounds to the abdomen, neck, and cheek. Josephine
    suffered three fatal gunshot wounds to the head. Sandra
    sustained a graze wound to the right shoulder and a gunshot
    wound to the head that led to her death after time spent on a
    respirator. She also suffered 23 stab and cutting wounds to the
    head, neck, right arm, torso, and back, as well as superficial
    wounds to the inside of her left wrist and forefinger, all inflicted
    by a pointed instrument such as a pair of scissors. From the
    nature of the stab wounds, it appeared Sandra was moving
    around when they were inflicted; she was shot after being
    5
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    stabbed and cut.     Toxicology reports on Bloom, Sr., and
    Josephine were both negative for drugs and alcohol.
    Various witnesses testified about events occurring in the
    days preceding the killings. Martin Medrano, an acquaintance
    of Bloom’s who testified at the first trial, was deceased by the
    time of the retrial; his prior testimony was read to the retrial
    jury. In April 1982, Bloom said he had a contract to kill someone
    and offered Medrano $1,200 to get him a gun. Medrano, a drug
    addict who was on parole, said he intended to take Bloom’s
    money but not give him a gun. Bloom approached Medrano
    several more times. Medrano asked if he had the money; Bloom
    told Medrano he would get it and that Medrano would read
    about the killing. At the time Medrano testified, he was in
    custody for armed robbery. He had seen Bloom in jail and
    reported his earlier dealings with him to a deputy sheriff. No
    promises were made to Medrano in connection with his
    testimony.
    Ricardo Avila testified that in 1982 he and his then-
    girlfriend, Christine Waller, both 14 years old, were friends of
    Bloom’s. They spent time with Bloom at the homes of Waller’s
    mother and of Bloom, Sr. According to Avila, Bloom and
    Bloom, Sr., argued frequently about everything Bloom did.
    Bloom never fought back physically. Two days before the
    killings, Avila was watching television with Waller in her
    family’s living room when he saw Bloom pass by outside the
    window holding a rifle. Avila heard “five or six pops” and went
    toward the back of the house, where he saw Bloom entering
    through a sliding door, hiding a rifle under his jacket. The day
    before the killings, Bloom, Sr., came to Waller’s residence
    looking for Bloom, who was not there. Avila went to Bloom’s
    workplace and told him his father had come looking for him.
    6
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom went to a pay phone, called his father, and said, “You’re
    running my life now, but you won’t be for long.”
    Waller testified at Bloom’s first trial but was unavailable
    for the retrial; her prior testimony was read to the retrial jury.
    In 1982, Waller had had a very close relationship with Bloom,
    who would often come over to her house and sometimes sleep
    there. On the evening of April 20, 1982, two days before the
    killings, she saw Bloom outside her house carrying a rifle she
    recognized as her brother’s toward a vacant field. The following
    day, Bloom was again at Waller’s house and was planning to
    spend the night; her mother asked her to wake him up the next
    day at 5:00 a.m. That evening, Bloom looked pale, quiet, and
    tense, the way he did when he was upset; later, however,
    Waller’s mother, Norma White, thought he looked normal. On
    the morning of April 22, Waller knocked on the door of the
    bedroom Bloom occupied but received no response. When she
    opened the door, the light was on and the bed looked like it had
    been slept in, but Bloom was not there.
    Whenever Waller saw Bloom with his father, Bloom, Sr.,
    appeared “always angry” at Bloom, who could never seem to
    satisfy him. Bloom would sometimes cry after confrontations
    with his father. During visits to the Bloom residence, Waller
    saw Bloom take good care of his stepsister Sandra, playing with
    her and fixing her food to eat.
    White’s son, Raul Rosas, testified he was living in White’s
    house at the time of the killings and knew Bloom. Rosas owned
    a .22-caliber semiautomatic rifle, which he initially kept
    unloaded in his bedroom but then kept in the trunk of his car
    after some gang members shot at him. He never showed the gun
    to Bloom. Rosas was at home on April 21, 1982, the day before
    7
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the killings, and saw Bloom, who appeared normal. The
    following day, after learning of the shootings, Rosas discovered
    his gun was missing and notified police.
    2. Defense case
    Bloom had pleaded not guilty and not guilty by reason of
    insanity to all charges. At the guilt phase, the defense presented
    evidence to show that Bloom was suffering from severe mental
    impairments that prevented him from forming malice. The
    defense also presented evidence suggesting that Bloom, Sr., had
    abused Bloom and that the killings were committed in the heat
    of passion.
    Bloom’s mother, Melanie Bostic,1 testified that Bloom, Sr.,
    was physically abusive and pushed her down a flight of stairs
    while she was pregnant with Bloom. Bloom, Sr., began hitting
    and slapping Bloom when he was still a baby. He would also
    scream at him, use foul language, and deliberately scare him.
    He once ripped apart Bloom’s favorite stuffed animal in front of
    him. He would proclaim he was God and that he was going to
    kill Bloom. Melanie left the marriage when Bloom was in the
    first grade. At the time, he seemed like a normal little boy, but
    he did not have any real friends; he instead had an imaginary
    friend named Tony.
    Robin Bucell was married to Bloom, Sr., for about three
    years after Melanie left the family. At the start of the marriage,
    Bloom was a small and scrawny 10-year-old and the focus of his
    father’s abuse. Bloom, Sr., would slap, beat, and belittle him.
    Bloom, Sr., also emotionally manipulated Bloom by telling

    son Byron Bostic by their first names. No disrespect is intended.
    8
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom that he loved him but his mother did not. Melanie,
    Bloom’s mother, visited irregularly, and although she was
    affectionate toward Bloom, her visits were marked by hostility
    and physical violence with Bloom, Sr., which upset Bloom.
    Bloom, Sr., would threaten to kill Bucell and members of her
    family, a threat she found credible because he claimed to be a
    Mafia hit man. Bloom, Sr.’s mother came to live with them for
    about a year, during which time he took her Social Security
    checks and was mean and rude to her. Bucell had a son, Eric,
    with Bloom, Sr. Eventually, in fear for their safety, she left with
    Eric and divorced Bloom, Sr. On cross-examination, Bucell
    testified that while she was married to Bloom, Sr., Bloom
    developed a kidney condition for which he had weekly medical
    appointments, but at no time did a doctor raise suspicions of
    physical abuse.
    Eric Bloom2 testified that his father married Josephine
    when he was five or six years old. Bloom, Sr., did not physically
    abuse Eric, but he did beat Bloom “all the time,” and Eric heard
    Bloom express fear of their father. Bloom, Sr., would dunk
    Bloom’s head in the toilet and throw plates at him. After one
    beating about a month before the killings, Bloom told Eric he
    couldn’t take much more of the pain and didn’t think he would
    live to his next birthday. When Bloom, Sr., and Josephine
    fought, Bloom would take Eric out of the house. Bloom would
    also get between Eric and his father when Bloom, Sr., yelled at
    Eric.
    Neuropsychologist Dale G. Watson offered expert
    testimony relating to Bloom’s mental state. Dr. Watson
    2
    Again, to avoid confusion, we will refer to Eric Bloom by
    his first name.
    9
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    evaluated Bloom in 1993 and again in 1999 and 2000,
    administering comprehensive neuropsychological tests. In
    neither test administration did Dr. Watson detect evidence of
    malingering.         The 1993 testing revealed “severe
    neuropsychological impairment” indicative of “very significant
    neuropsychological deficits.” The impairment was associated
    with both the left and right hemispheres, but primarily the
    right. Bloom’s deficits affected his ability to read social cues and
    process emotions. He also exhibited significant impairment in
    problem solving. Bloom’s verbal IQ was 95 — average being
    100 — but his performance IQ was 67, in the very impaired
    range; the striking disparity between the two scores suggested
    the presence of brain damage or impairment. The 1999 and
    2000 testing yielded results consistent with the prior testing,
    with a verbal IQ of 112, in the high average range, and a
    performance IQ of 65, in the extremely low range, with right
    hemisphere impairment still evident. During the evaluation,
    Bloom exhibited or related certain compulsive behaviors and
    “oddities,” such as reciting the entire sequence of English
    monarchs. His developmental anomalies, such as dysmorphic
    facial features and the presence of two kidneys on one side of his
    body, were consistent with birth defects. Such defects can be
    related to fetal alcohol syndrome or fetal Dilantin syndrome, a
    consequence of an antiseizure medication now known to affect
    fetal health that Dr. Watson testified Bloom’s mother took while
    pregnant. Further, according to Dr. Watson, Bloom likely
    suffered brain damage in a drowning incident when he was two
    years old. Loss of oxygen supply can cause permanent brain
    deficits and personality changes. Dr. Watson diagnosed Bloom
    as having cognitive disorder not otherwise specified and/or
    severe nonverbal neurocognitive dysfunction. His report on his
    10
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    2000 evaluation opined that at the time of the homicides Bloom
    was, because of a mental defect, unable to comprehend his duty
    to govern his conduct in accordance with the law. Dr. Watson
    concluded that Bloom was in a dissociative state from the time
    he shot his father until the killings were over. Dr. Watson was
    uncertain whether Bloom was dissociating when he and his
    father were going up and down the street before the shooting.
    Forensic psychiatrist Mark J. Mills also testified for the
    defense in the guilt phase. Dr. Mills had become involved in the
    case in 1993 when the judge who was then presiding over
    Bloom’s federal habeas corpus proceedings consulted him
    concerning issues related to Bloom’s mental health. (The retrial
    jury was not told the precise nature of those proceedings.) In
    1999, trial counsel retained Dr. Mills and provided him with
    voluminous records he had not seen at the time of the earlier
    consultation. Review of the additional material led Dr. Mills to
    revise his earlier opinions. Specifically, he diagnosed Bloom
    with Asperger Syndrome, a developmental disorder on the
    autism spectrum, and concluded Bloom had suffered extreme
    emotional and physical abuse as a child. Abused children often
    dissociate — that is, they enter a state of partial consciousness
    or partial awareness — as a way of coping with the pain and fear
    engendered by the abuse, and Bloom was more prone to
    dissociation by virtue of the brain dysfunction Dr. Watson had
    identified. Dr. Mills believed Bloom was in a dissociative state
    around the time of the killings, a conclusion for which he found
    support in the testimony of eyewitnesses Dave Hughes and
    Moises Gameros regarding Bloom’s apparently ambivalent and
    purposeless actions immediately after the shootings. Bloom was
    also often paranoid and tolerated the administration of
    antipsychotic medication at levels that would sedate an
    11
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    ordinary person. Dr. Mills acknowledged that although in
    general determining a person’s mental state 11 years after the
    fact is very difficult, a diagnosis of Asperger Syndrome can be
    reliably made at a long remove because it is a lifelong
    developmental condition; if it exists currently, it would have
    existed in the past. Asperger Syndrome impaired Bloom’s social
    and emotional reciprocity and ability to empathize, although he
    retained an intellectual appreciation of the effects of his actions.
    A third mental health expert, psychiatrist William Vicary,
    testified that he had originally been appointed by the trial court
    in May 1984 to assess Bloom’s competence for a hearing in a low-
    complexity matter.3 Dr. Vicary talked with Bloom in jail,
    reviewed his jail medical records, and spoke with sheriff’s
    deputies who knew Bloom. At that time, Bloom was paranoid
    and to some extent out of touch with reality. Dr. Vicary
    concluded that Bloom understood the nature and purpose of the
    proceeding. Dr. Vicary also found, though with a lower level of
    confidence, that Bloom could rationally participate in the
    proceeding.
    In 1993, Dr. Vicary reviewed additional records and
    interviewed Bloom again. After doing so, he reconsidered his
    earlier opinion and concluded Bloom had not been mentally
    competent for most of the prior proceedings. Dr. Vicary believed
    Bloom suffered from serious mental illness (which he did not
    diagnose specifically) and brain dysfunction. The combination
    of mental illness and brain dysfunction made Bloom likely to
    3
    The retrial jury was not told the earlier hearing was the
    original sentencing proceeding in this case.
    12
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    “snap” — to suffer a psychotic break or an “emotional explosion,”
    or to dissociate — under stress.
    B. Sanity Phase
    Following Bloom’s convictions in the guilt phase, the jury
    heard the trial of Bloom’s insanity defense.
    Psychiatrist Philip E. Wolfson testified for the defense
    that he had examined Bloom over a total of about 20 hours
    between 1990 and 1992 at the request of Bloom’s then-attorney,
    seeking to understand Bloom’s state of mind at the time of the
    killings. Bloom had described various versions of events over
    the years since the crimes, and to get from him what Dr. Wolfson
    termed “the closest approximation of the truth,” the psychiatrist
    had to earn his trust and break down his defenses.
    Dr. Wolfson concluded that in the year or so before the
    killings Bloom began to suffer from significant mental illness,
    which he diagnosed as a mixed personality disorder with
    borderline and dependent features. Borderline personality
    disorder is characterized by a pervasive pattern of instability of
    interpersonal relationships, self-image, moods, and emotions, as
    well as marked impulsivity, beginning by early adulthood.
    Bloom’s interpersonal relationships were poorly developed; he
    tended to either idealize people in his life or put them down. He
    had an extremely poor and unstable self-image and was often
    the butt of others’ derision. His moods and feelings were
    variable and unstable. At times Bloom felt extremely depressed
    and worthless; at other times he was extremely agitated; and in
    some moments he seemed psychotic. His behavior during his
    time in high school (classmates described him as weird and
    strange) and in the Navy (he failed to follow basic hygiene or
    maintain appropriate comportment), as well as his commission
    13
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    of an attempted robbery with a BB gun, all revealed his
    impulsivity and lack of control. Fear of abandonment is
    characteristic of borderline personality disorder and was a
    constant theme in Bloom’s life from his mother’s leaving the
    family, to his father’s disappearances and jail time, until shortly
    before the killings, when Bloom, Sr., was reportedly about to put
    the house up for sale and move, leading Bloom to fear he would
    be left behind. The abandonment and traumatic punishment
    Bloom experienced contributed to his chronic feelings of
    emptiness. In the year before the homicides Bloom also
    experienced transient stress-related paranoid ideation and
    dissociative symptoms to a degree that sometimes seemed
    psychotic.
    Bloom also exhibited less fully developed traits of
    dependent personality disorder, which is characterized by a
    pervasive and excessive need to be taken care of that leads to
    submissive and clinging behavior and fears of separation
    beginning by early adulthood. Dr. Wolfson attributed Bloom’s
    apparent inability to leave his father’s home, despite being
    abused and denigrated, to the effects of this disorder.
    Dr. Wolfson testified that when Bloom was about to
    graduate from high school, his living situation was unstable and
    he lacked consistent support. He had no real career path and,
    to his distress, was discharged from the Navy as unfit after an
    enlistment of less than a month. After Bloom’s discharge, as
    Bloom, Sr., was going to jail for fraudulent business activities,
    Bloom stayed briefly at his mother’s house until he himself was
    jailed for the aforementioned robbery with a BB gun.
    Dr. Wolfson related that in connection with that crime, some
    five months before the homicides, Dr. Richard Naham had
    evaluated Bloom and found him to be paranoid and on the verge
    14
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    of a nervous collapse. Dr. Naham wrote in his report at the time
    that without inpatient psychiatric treatment Bloom would
    continue to present a danger to others.
    Dr. Wolfson further testified that, following his release
    from custody, Bloom moved in with Bloom, Sr., who meanwhile
    had married Josephine, but he also spent considerable time in
    the home of his friend Christine Waller. Bloom idealized
    Waller’s mother, Norma White, as the mother he wished he
    could have had. Bloom’s relationship with his father continued
    to deteriorate, as Bloom, Sr., took Bloom’s money for his own
    purposes and tried to get Josephine to sign over her rights to
    their house. Bloom, Sr., had engaged in numerous other scams
    that Bloom recognized and disapproved of. Bloom’s frustrations
    exacerbated his confusion, impulsivity, and irrationality.
    Bloom’s morality was split, making him both a person with “a
    high moral sense” and someone “who could be a con himself.”
    Dr. Wolfson testified that Bloom had long entertained
    homicidal thoughts toward his father. Seeing a rifle at White’s
    house catalyzed a feeling that he could actually kill Bloom, Sr.
    Bloom started preparing a fictitious alibi involving intruders
    trying to break into the White residence, but his planning was
    poor and unrealistic. He was later seen by members of the
    White family practicing with the rifle. On the night of the
    killings, he took the rifle and returned to his father’s house
    intending to kill Bloom, Sr., but, in Dr. Wolfson’s opinion, he was
    not planning to harm Josephine or Sandra. At the moment he
    shot Bloom, Sr., Bloom lacked the capacity to conform his
    conduct to the requirements of the law because he did not view
    shooting his father as unjust. According to Dr. Wolfson, Bloom’s
    belief that the only way out of his difficult situation was to shoot
    his father, and then his going ahead and doing it, was insane.
    15
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    As Dr. Naham’s evaluation had warned, Bloom’s connection to
    reality had loosened and he had become psychotic. When Bloom
    shot Josephine and Sandra, he was in an altered state, acting
    without a mental process.
    Dr. Wolfson acknowledged that Bloom had told many lies
    and given different versions of the events at issue over multiple
    interviews, and Dr. Wolfson had had to seek corroboration for
    Bloom’s statements.        In response to the prosecutor’s
    hypothetical question, Dr. Wolfson could think of no situation in
    which it would be sane and rational for a person who had just
    killed his father to murder two eyewitnesses to the killing.
    Dr. Wolfson believed it would be irrational to wear a trench coat
    to hide the fact one is carrying a rifle, as Bloom did in 1981 in
    connection with an incident unrelated to the homicides, the
    previously mentioned attempted robbery with a BB gun.
    Bloom’s planning of the killing of his father and the continuation
    of his goal-directed behavior after the killing similarly, in
    Dr. Wolfson’s view, reflected insanity. In his fifth interview
    with Dr. Wolfson, Bloom stated: “If things had gone right,
    [Bloom, Sr.,] would have gotten hit when he was alone. It’s
    tricky because Josephine and Sandra were just witnesses.
    They’d still be alive.” The statement did not make sense to
    Dr. Wolfson “given the whole construction of the facts,” and he
    noted Bloom later retracted it. Dr. Wolfson believed Bloom was
    telling the truth when he later claimed he did not know why he
    killed Josephine and Sandra because it was while making this
    claim, as opposed to the other explanations he had offered in
    recounting their killings, that he had the most profound
    emotional reaction and remorse.
    Dr. Wolfson disagreed with some of the other experts who
    had been consulted in the case. He did not agree with Dr. Mills
    16
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    that Bloom had Asperger Syndrome. Nor did he agree with
    another doctor who had opined that Bloom was not psychotic, or
    a doctor who had opined that Bloom was sane when he killed his
    father. Finally, he did not agree with Dr. Watson’s diagnosis of
    severe brain impairment.
    The prosecution presented no evidence at the sanity
    phase.
    C. Penalty Phase
    1. Prosecution case
    The prosecution presented victim impact evidence as well
    as evidence of Bloom’s involvement in several prior incidents of
    violence or threatened violence, including: (1) a November 1981
    robbery in which Bloom pulled a BB gun out of a trench coat,
    grabbed the purse of a woman attending a Bible study group,
    and fled after he was thwarted; (2) a May 1984 incident at the
    law library in Men’s Central Jail, in which Bloom was seen
    holding a knife and running away from another inmate, who
    was bleeding; and (3) Bloom’s February 1982 statement to
    Josephine’s uncle, at Josephine’s wedding to Bloom, Sr., that he
    wanted to kill Josephine and Sandra because they were “in the
    way.” Bloom added that he had “a half brother that’s in the way
    and I don’t need two more in the way,” and threatened
    Josephine’s uncle that if he got “in the way, I will kill you.”
    2. Defense case
    Bloom successfully moved to discharge his attorneys and
    represent himself at the penalty phase. He presented the
    testimony of several inmates and sheriff’s deputies regarding
    his character.
    Three female witnesses testified that while incarcerated
    they had met Bloom on the bus transporting inmates from jail
    17
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    to court. Each testified Bloom was polite and respectful. The
    inmate Bloom had stabbed in the law library testified that
    Bloom explained he “met a girl who apparently read [about his]
    case in the newspaper at the time and [he] wanted to catch a
    case to stay down there.” Three sheriff’s deputies testified that
    they had interacted with Bloom in the courthouse lockup, the
    courtroom, and the jail, respectively, and that he had behaved
    in a cooperative and respectful manner.
    The defense also called Paul Mones, an attorney, author,
    and lecturer who specializes in parricides — that is, cases
    involving children, teens, and adults who kill their parents.
    After studying Bloom’s case, Mones formed the opinion that at
    the root of the homicides was years of abuse Bloom, Sr.,
    perpetrated on Bloom.
    Bloom’s half brother Byron Bostic testified that since he
    was eight or nine years old, he had been visiting Bloom at the
    prison, bringing his own family as he grew older. The visits were
    always peaceful; there were never any problems, and Bloom was
    never violent or threatening. Anna Maria Dean, age 10 and the
    daughter of Byron’s partner, testified that she had visited Bloom
    at the prison, loved him, and was not afraid of him.
    Melanie Bostic, Bloom’s mother, testified about
    Bloom, Sr.’s, abusive conduct toward Bloom, first striking him
    when he was a month old, beating him when he was a toddler,
    and eventually threatening to kill him. Melanie also testified
    about her relationship with Bloom, Sr., which was fraught with
    arguments and violent abuse. Melanie left her marriage to
    Bloom, Sr., when Bloom was in elementary school. When Bloom
    visited her after the divorce, Melanie’s boyfriends sometimes
    18
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    abused him, and Bloom also witnessed them committing acts of
    violence against her.
    Robin Bucell was married to Bloom, Sr., from August 1974
    to August 1977. Bloom, Sr., forced her and Bloom to lie for him
    in his fraudulent schemes, threatening them with bodily harm
    if they refused. She had a child, Eric, with Bloom, Sr.;
    eventually, out of concern for her and Eric’s safety, Bucell left
    Bloom, Sr.
    Superior Court Judge Michael Hoff testified that Bloom’s
    case was assigned to his courtroom from July 1998 to September
    2000. During that period, Bloom appeared to Judge Hoff to be
    competent. On multiple occasions, Bloom unsuccessfully sought
    to fire his appointed counsel because he disagreed with the
    psychiatric defense they were planning to present; Bloom once
    attempted to assert his right to represent himself, although he
    later changed his mind. Judge Hoff did not know whether or not
    Bloom was sincere in his requests. Some of the things Bloom
    said “made sense” and were “very skillful”; others were
    “somewhat stupid.”
    Finally, Bloom testified on his own behalf and provided his
    account of the crimes and incidents described in the prosecution
    case. Bloom argued that his father got what he deserved, and
    Bloom’s only regret was not killing him when he was 16 or 17,
    because then his father would never have been involved with
    Josephine and Sandra. Bloom denied ever asking Medrano for
    a gun, offering him money for a gun, or telling him he was
    planning to kill someone. Bloom confirmed the account of the
    jailhouse stabbing and claimed he tried to commit the church
    robbery because his father had needed money and told him to
    get him some.
    19
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom testified it was counsel’s idea, not his, to present a
    mental capacity defense; he denied he was mentally impaired.
    He reviewed the diagnostic criteria for Asperger Syndrome and
    argued he met none of them.
    II. DISCUSSION
    A. Pretrial Issues and Issues Affecting the Entire
    Trial
    1. Constitutionality of retrial
    The murders in this case occurred in 1982. Bloom was
    first convicted in late 1983 and sentenced in 1984. In 1997, a
    federal court granted Bloom relief from his conviction and
    sentence on the ground that his counsel had rendered
    constitutionally ineffective assistance in the investigation,
    preparation, and presentation of mental health evidence at trial.
    (Bloom v. Calderon, 
    supra,
     
    132 F.3d 1267
    .) Retrial took place in
    2000, more than 18 years after the crimes. By that time, the
    two mental health professionals who had examined Bloom
    shortly before and after the offense, Dr. Arthur S. Kling and
    Dr. Richard Naham, had become unavailable.
    Before the retrial, the defense moved to dismiss the
    charges, contending the experts’ unavailability deprived Bloom
    of a meaningful opportunity to present a complete defense. The
    trial court denied the motion, though it also ruled there could be
    no mention at the retrial of the verdicts from the first trial. (See
    Pen. Code, § 1180.) The defense then filed a supplemental
    motion renewing the argument that the murder charges should
    be dismissed or, in the alternative, that the court should
    preclude charges greater than manslaughter, preclude the
    possibility of the death penalty, or provide for other curative
    measures to reduce the prejudice from the passage of time and
    20
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    from former trial counsel’s constitutionally inadequate
    performance. The court denied the supplemental motion.
    Bloom contends the court’s rulings denied him his rights
    to due process, to present a defense, and to the effective
    assistance of counsel. He argues that the passage of time before
    retrial, and the consequent unavailability of the two expert
    witnesses, critically undermined his principal defense —
    namely, that he lacked the mental state required for murder.
    The defense was forced to present experts who had not
    personally examined Bloom near the time of the offenses, a point
    the prosecution highlighted in cross-examination and closing
    argument.
    We find no error in the trial court’s decision to allow the
    retrial to take place, notwithstanding the unavailability of
    Drs. Kling and Naham. Bloom relies on a series of cases
    concerning the constitutional right to a speedy trial, which
    observe that the loss of witnesses and other evidence may be a
    cost of pretrial delay. (E.g., Barker v. Wingo (1972) 
    407 U.S. 514
    ,
    532.) But case law also makes clear that following a reversal of
    a prior conviction, the prosecution is entitled to retry the
    defendant “ ‘in the normal course of events’ ” (People v.
    McDowell (2012) 
    54 Cal.4th 395
    , 413, quoting United States v.
    Ewell (1966) 
    383 U.S. 116
    , 121), and no speedy trial inquiry is
    even necessary unless the prosecution engages in undue delay
    in proceeding with retrial (see Barker, at p. 530; McDowell, at
    pp. 414–415). This is true even where the process of judicial
    review results in substantial delays. (See McDowell, at pp. 413–
    416 [finding no error where penalty retrial took place 15 years
    after initial penalty phase].) Here, Bloom does not argue that
    the state unnecessarily delayed retrial after the federal court
    granted him habeas relief. The great bulk of the delay of which
    21
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    he complains is instead attributable to the process of appeal and
    postconviction review.      Where, as here, “defendant has
    benefitted from the careful and meticulous process of judicial
    review, he cannot now complain that the process ‘which exists
    to protect him has violated other of his rights.’ ” (Id. at p. 415.)
    Even so, Bloom contends that the trial court should have
    dismissed the case or taken steps to limit the prejudice caused
    by the unavailability of the two expert witnesses. He points to
    People v. Sixto (1993) 
    17 Cal.App.4th 374
     (Sixto), which, like this
    case, involved a retrial following reversal of a conviction due to
    former      trial     counsel’s    constitutionally     ineffective
    performance — there, failure to have blood samples properly
    analyzed to support a drug-related diminished capacity defense.
    Also, much as in this case, relevant evidence became
    unavailable before the retrial occurred; the blood sample had not
    been preserved. The Sixto court addressed the possibility that
    the loss of evidence might require curative measures, though it
    ultimately concluded that the loss of the defendant’s blood
    sample did not require such measures in the defendant’s case.
    (Id. at p. 396; see id. at p. 399 [courts have discretion to
    determine appropriate admonitions or other measures].) The
    court explained that “retrial counsel were able to bring out
    significant evidence which was not presented at the first trial.
    Thus, the second trial was not rendered a meaningless, futile
    replay of the first proceedings, even absent some sort of curative
    measures by the trial court.” (Id. at p. 396.)
    Sixto does not help Bloom’s case. The unavailability of
    Bloom’s original experts did not prevent him from putting on a
    mental state defense at the retrial; indeed, several experts
    testified on his behalf. Nothing in Sixto or any other case Bloom
    has cited supports the argument that due process nonetheless
    22
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    required the extreme step of dismissing or limiting the charges
    against him. And to the extent Bloom argues that the trial court
    erred in failing to instruct the jury not to consider the passage
    of time in its evaluation of the evidence, neither Sixto nor any
    other cited case supports the argument. (See Sixto, supra, 17
    Cal.App.4th at pp. 390–392, 401–402 [upholding trial court’s
    refusal to give the defendant’s requested curative instructions].)
    Here, the requested instructions would have hampered the
    jury’s realistic evaluation of the evidence; even defense expert
    Dr. Mark Mills acknowledged that the passage of time affected
    his ability to discern what Bloom was like when the offenses
    were committed (though Dr. Mills still maintained that the
    particular Asperger Syndrome diagnosis he had reached was
    valid regardless of the passage of time).
    Bloom raises various other objections to the conduct of the
    retrial. Bloom argues that even though the trial court had
    forbidden references to the verdicts from his first trial, the
    prosecution improperly injected the prior trial into the retrial by
    referring to or relying on the prior testimony of witnesses.4 He
    also contends that the prosecution improperly asked questions
    that either obliquely referred to, or solicited responses that
    referred to, Bloom’s prior incarceration. But contrary to Bloom’s
    arguments, none of these references violated either Penal Code
    section 1180, which forbids references to former verdicts or
    findings, or his due process rights. None of the references to
    witnesses’ prior testimony directly revealed the verdict reached
    4
    We address below, in part II.B.2., Bloom’s contention that
    the unavailability of lay witnesses Christine Waller and Martin
    Medrano at the retrial undermined his defense and prevented a
    fair trial.
    23
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    in Bloom’s prior trial. Nor did they encourage the jury to draw
    inferences that risked “implying prior criminality,” thus
    “prejudic[ing] defendant in the eyes of the jury.” (People v.
    Kessler (1963) 
    221 Cal.App.2d 187
    , 192.) It is true that the
    references would have led jurors to assume Bloom had
    previously been tried and that he had been detained before the
    retrial, but as both sides in the case acknowledged, that
    information was inevitably going to come out and on its own
    raised no unacceptable risk of prejudicing Bloom in the eyes of
    the jury.
    2. Failure to conduct competency proceedings
    Bloom contends the trial court violated his state and
    federal constitutional rights by failing to suspend his trial and
    institute competency proceedings at various points in the
    proceeding as information calling his competence into question
    came to its attention. Even if no single piece of evidence
    compelled such a response from the trial court, he contends, the
    cumulative weight of the information should have led the court
    to declare a doubt as to Bloom’s competency and institute
    proceedings under Penal Code section 1368.5 We reject the
    argument.
    5
    Penal Code section 1368 provides for suspension of the
    criminal proceedings and a hearing on the defendant’s
    competence to stand trial whenever a doubt about competence
    arises in the trial court. (Pen. Code, § 1368, subds. (a), (b).)
    Proceedings are suspended until competence is determined, but
    the jury remains impaneled and sworn unless the court
    determines undue hardship would result if the jurors remained
    on call. If the defendant is determined to be incompetent, the
    jury is dismissed. (Id., subd. (c).)
    24
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    a. General principles
    “ ‘Both the due process clause of the Fourteenth
    Amendment to the United States Constitution and state law
    prohibit the state from trying or convicting a criminal defendant
    while he or she is mentally incompetent.’ (People v. Rogers
    (2006) 
    39 Cal.4th 826
    , 846 [
    48 Cal.Rptr.3d 1
    , 
    141 P.3d 135
    ]; see
    [Pen. Code,] § 1367, subd. (a); Drope v. Missouri (1975) 
    420 U.S. 162
    , 172 [
    43 L.Ed.2d 103
    , 
    95 S.Ct. 896
    ].) ‘A defendant is
    incompetent to stand trial if [he] is unable to consult with [his]
    attorney with a reasonable degree of rational understanding or
    lacks a rational and factual understanding of the proceedings
    against [him].’ ” (People v. Woodruff (2018) 
    5 Cal.5th 697
    , 720–
    721.)
    “ ‘The decision whether to order a competency hearing
    rests within the trial court’s discretion, and may be disturbed
    upon appeal “only where a doubt as to [mental competence] may
    be said to appear as a matter of law or where there is an abuse
    of discretion.” [Citation.] When the court is presented with
    “substantial evidence of present mental incompetence,”
    however, the defendant is “entitled to a section 1368 hearing as
    a matter of right.” [Citation.] On review, our inquiry is focused
    not on the subjective opinion of the trial judge, but rather on
    whether there was substantial evidence raising a reasonable
    doubt concerning the defendant’s competence to stand trial.
    [Citation.] . . . A trial court reversibly errs if it fails to hold a
    competency hearing when one is required under the substantial
    evidence test.’ ” (People v. Woodruff, supra, 5 Cal.5th at p. 721.)
    Bloom contends that the trial court should have declared
    a doubt and held a competency hearing at each of the three
    25
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    phases of the trial: guilt, sanity, and penalty. We address in
    turn Bloom’s competence at the guilt and sanity phases.6
    b. Guilt phase
    Bloom contends that during the guilt phase of the trial,
    various circumstances were made known to the court that
    should have prompted it to suspend proceedings. As an initial
    matter, when the case was returned to Los Angeles County
    Superior Court for retrial in 1998, the court was aware that the
    1983 proceedings had included a trial pursuant to Penal Code
    section 1368, just before sentencing, in which the jury had found
    Bloom competent. The federal court had also vacated Bloom’s
    1983 convictions on grounds of ineffective assistance of counsel
    for failure to adequately prepare and present a mental disorder
    defense. (Bloom v. Calderon, 
    supra,
     132 F.3d at pp. 1277–1278.)
    In September 1998, soon after Bloom was received in county jail
    pending retrial, the court received notice that Bloom had been
    admitted to a forensic inpatient program under Welfare and
    Institutions Code section 5150 on a finding that he was gravely
    disabled or a danger to himself or others. Two months later,
    Bloom made a Marsden7 motion seeking substitution of counsel.
    During a hearing on the motion, Bloom complained that his trial
    counsel were insisting on presenting a psychiatric defense
    against his wishes because his federal appellate counsel had
    instructed them to do so.
    Near the beginning of the retrial, in January 1999, Judge
    Hoff — to whom the case was initially assigned for retrial —
    6
    We need not address Bloom’s competence during the
    penalty phase because, as discussed post at page 45, the penalty
    verdict must be reversed for other reasons.
    7
    People v. Marsden (1970) 
    2 Cal.3d 118
     (Marsden).
    26
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    ordered an evaluation of Bloom’s competence in connection with
    his motion for self-representation, but Bloom withdrew his
    motion and no evaluation took place.
    Before the start of the retrial — in connection with a
    motion to exclude the prior testimony of Martin Medrano and
    Christine Waller (see pt. II.B.2., post) — the defense presented
    the 1993 declarations of five mental health professionals opining
    that Bloom had been incompetent at his first trial because of
    severe, long-standing mental illness and brain damage. At the
    hearing on the motion, defense counsel characterized Bloom’s
    present competence as “a fluid issue” that was being assessed
    “day to day.” The prosecutor, seeking clarity regarding whether
    or when Bloom’s competence would be litigated during the
    retrial, suggested that if he was incompetent at the first trial,
    there was no reason to believe he was competent for retrial. The
    trial court observed a new physical behavior on Bloom’s part (he
    was “swaying”), but did not suspend proceedings for a
    competence hearing.
    On the day before opening statements, the parties and the
    court discussed Bloom’s desire to represent himself in the
    penalty phase should the case get that far. The discussion
    returned to the issue of Bloom’s competence. Defense counsel
    Seymour Applebaum said that in his view “Mr. Bloom has
    always been skirting the edges of incompetence,” particularly as
    to his ability to cooperate with counsel, but pointedly stopped
    short of declaring a doubt as to Bloom’s present competence.
    Alluding to “the voluminous materials in preparation that arose
    out of the various appeals and ultimately the habeas
    proceedings and what the lawyers and the various mental
    health professionals did, our predecessors did,” counsel
    explained that in the posture of this case Bloom’s cooperation in
    27
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the factual aspects of preparation for trial was unnecessary.
    “But as we get closer, he’s again skirting the edges of his ability
    to cooperate with counsel, interference in the trial process due
    to a mental illness, disease or defect, and I think the court needs
    to be aware of this. [¶] It’s something that’s concerned me, it’s
    something that’s always troubled me, and if this were a different
    type of case in terms of how it came to us, vis-à-vis the
    preparation that needed to be done, where I needed to confer
    with the client, needed to plan strategy with the client, I would
    have declared a [Penal Code section] 1368 doubt eons ago.
    [¶] . . . [¶] Quite truthfully, if there is interference where he is
    in my view not cooperating with preparation of the case in a
    rational way, where he starts interfering with the tactical
    process, my view is that I will have to declare a doubt and then
    we’ll do what we have to do.” The retrial proceeded without a
    hearing on competence under section 1368.
    From time to time throughout the retrial proceedings,
    Bloom engaged in odd behaviors, calling mental health expert
    Dr. Sharma “a Christian spy”; suggesting there were poisoned
    ants on cookies provided by the jail; referring to defense counsel
    Tonya Deetz as the “consigliere of the principality of Israel,” the
    last phrase (the principality of Israel) seemingly referring to
    himself; referring to prosecutor Shellie Samuels as “one of [his]
    subjects”; and calling Judge Schempp the “lady of the court.”
    When Bloom learned that Judge Hoff’s son had been in his high
    school class, Bloom sought to question both the judge and his
    son under oath and asked for substitution of counsel for failing
    to seek the judge’s recusal. At times, Bloom argues, his
    discussions about the anticipated penalty phase raised
    questions about his understanding of the nature of mitigation.
    For example, he expressed glee at the prospect of having Roz
    28
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Kelly, a former actor whom he had met while in jail, testify on
    his behalf.
    Bloom argues that all this information raised a doubt as
    to his competence in the guilt phase. He acknowledges defense
    counsel’s assertion that Bloom had not yet crossed the threshold
    of incompetence but contends the assertion must be disregarded
    because counsel’s understanding of incompetence was at odds
    with constitutional standards. That is, he claims, counsel’s
    statement that in another case counsel would have declared a
    doubt “eons ago” was tantamount to saying that Bloom was
    presently incompetent, but in this particular case counsel did
    not need him to be otherwise. In any event, he contends,
    counsel’s belief did not eliminate the trial court’s independent
    obligation to initiate competency proceedings in the face of
    substantial evidence objectively raising a reasonable doubt
    regarding Bloom’s competence.
    We disagree with Bloom that, on these facts, the trial court
    was required to declare a doubt under Penal Code section 1368
    before or during the guilt phase of the retrial. “To raise a
    doubt . . . we require more than ‘mere bizarre actions’ or
    statements, or even expert testimony that a defendant is
    psychopathic, homicidal, or a danger to him- or herself and
    others. [Citations.] . . . [Citation.] Defendant’s trial demeanor
    is relevant to, but not dispositive of, the question whether the
    trial court should have suspended proceedings under section
    1368.” (People v. Mickel (2016) 
    2 Cal.5th 181
    , 202.) Although
    the trial court was aware that Bloom had a history of mental
    illness and although the court observed occasional odd
    behaviors, neither fact, without more, gave rise to a duty to
    suspend proceedings and conduct a formal evaluation of Bloom’s
    ability to understand the proceedings against him and assist
    29
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    rationally in his own defense. (See ibid.; People v. Blair (2005)
    
    36 Cal.4th 686
    , 714.) Nor, contrary to Bloom’s argument, did
    the trial court have a duty to inquire into Bloom’s psychiatric
    medication, at least absent any evidence that defendant’s
    competence hinged on compliance with a medication regimen.
    (Cf. People v. Rodas (2018) 
    6 Cal.5th 219
    , 235.)8
    Bloom relies heavily on the expert declarations presented
    in support of the pretrial motion to exclude the Medrano and
    Waller testimony, which opined that Bloom had been
    incompetent at the original trial. The jury at that trial had
    determined otherwise. But in any event, the declarations
    opined that Bloom had been incompetent more than a decade
    before the retrial; they did not opine on Bloom’s present ability
    to understand the proceedings against him or consult rationally
    with his attorneys. Notably, several of these same experts
    examined Bloom again in advance of retrial to assess the
    validity of a possible sanity defense, and none opined that Bloom
    was at that time incompetent to stand trial. This case is thus
    unlike People v. Wycoff (2021) 
    12 Cal.5th 58
    , in which an expert
    who was “appointed to address defendant’s competence to
    represent himself . . . also addressed, in detail, defendant’s
    competence to stand trial,” declaring him to be incompetent. (Id.
    at p. 76; see id. at p. 78.) There, we held that contemporaneous
    8
    To the extent Bloom may be understood to suggest that
    Dr. Mills’s testimony diagnosing him with Asperger Syndrome
    obligated the trial court to appoint the director of the regional
    center to evaluate him under Penal Code section 1369, he is
    mistaken; such an obligation arises only when a doubt regarding
    a defendant’s competence exists and the court suspects the
    defendant has a developmental disability. (Pen. Code, § 1369,
    subd. (a)(3); People v. Sattiewhite (2014) 
    59 Cal.4th 446
    , 466.)
    30
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    expert    opinion    constituted     substantial   evidence of
    incompetence, such that the court abused its discretion by
    failing to suspend proceedings. (Id. at p. 88.) Here, where
    several experts evaluated Bloom before the retrial and none
    concluded that he was incompetent, we cannot say the court
    abused its discretion by failing to suspend proceedings.
    Finally, in multiple discussions of the issue, defense
    counsel declined to raise a doubt about Bloom’s present
    competence, even as counsel acknowledged the issue was close
    and that he might raise such a doubt in the future. Bloom
    argues that defense counsel may have misunderstood the
    relevant standard, at one point suggesting that a doubt would
    have been declared “eons ago” in a different case. What counsel
    meant by this statement is, in context, ambiguous. Certainly, if
    counsel was suggesting that whether to declare a doubt was
    affected by the “type of case” or the nature of the work needed
    for counsel to prepare a defense, the suggestion was incorrect.
    It was Bloom’s ability to assist, not counsel’s need for assistance,
    that mattered. (See, e.g., People v. Mickel, supra, 2 Cal.5th at
    p. 202 [“[T]he focus of the competence inquiry is on a defendant’s
    understanding of the criminal proceedings against him or her
    and the ability to consult with counsel or otherwise assist in his
    or her defense”].) But counsel did not elaborate on the comment,
    leaving its import unclear.9 Counsel did, however, clearly
    decline to raise a doubt about Bloom’s present incompetence.
    And although counsel raised concerns about the possibility that
    9
    We have not been asked to, and do not, evaluate whether
    counsel’s potential misapprehension of the standard constituted
    ineffective assistance; as we have previously noted, such
    questions are best left to resolution on habeas corpus. (See
    People v. Mendoza Tello (1997) 
    15 Cal.4th 264
    , 267.)
    31
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Bloom would not be able to rationally consult with his attorneys
    in the future, counsel also acknowledged those concerns had not
    yet been realized. Under those circumstances, the court was not
    obligated to suspend proceedings.
    c. Sanity phase
    Bloom next contends the trial court should have
    suspended proceedings during the sanity phase. Bloom had
    absented himself from the sanity phase proceedings. On the day
    the jury began to deliberate about whether Bloom was insane at
    the time of the capital crimes, defense counsel Applebaum told
    the court there had been “substantial changes in the last couple
    of days with Mr. Bloom” that led him to declare a doubt
    regarding his competence to stand trial. At that point, Bloom
    contends, the court had before it other substantial evidence
    raising a doubt regarding his competence, including his decision
    to absent himself from the sanity phase and Dr. Vicary’s guilt
    phase testimony to the effect that Bloom was more likely than a
    normal person to suffer a breakdown or “snap” under stressful
    circumstances such as a criminal trial. Hearing experts testify
    he was mentally ill — a proposition he adamantly denied —
    might exacerbate the stress.
    In response to counsel’s declaration of doubt, the trial
    court stated that Bloom’s ability to cooperate with counsel was
    unimportant at the time because “[w]e are merely waiting for
    the verdict to come in the sanity phase.” Bloom contends the
    court’s response was both legally and factually wrong. Bloom
    argues that as a matter of law, a doubt about competence can
    arise during jury deliberations. And as a factual matter, Bloom
    argues, his ability to cooperate with counsel would soon become
    crucial when, after seven days of deliberations, the jury was
    32
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    unable to reach a sanity verdict on counts 2 and 3, the killings
    of Josephine and Sandra; at that point, his inability to rationally
    consult with counsel led him to irrationally withdraw his plea of
    not guilty by reason of insanity.
    We agree with Bloom that doubt can arise during
    deliberations. But the alleged harms Bloom identifies occurred
    after deliberations had concluded, at a point when it would have
    been clear to all that his competence did in fact matter. The
    trial court was under an unquestioned continuing obligation to
    suspend proceedings if it harbored a doubt as to Bloom’s
    competence — an obligation it surely understood — and yet the
    court did not do so. When a court harbors a doubt about the
    defendant’s competence, Penal Code section 1368 requires the
    court to solicit defense counsel’s opinion on the matter and to
    hold a competency hearing if counsel informs the court the
    defendant may not be competent. (Pen. Code, § 1368, subds. (a)
    & (b).) But as we have previously explained, there is no similar
    obligation if the court harbors no such doubt; the court is “under
    no duty to hold a competency hearing based solely on counsel’s
    opinion that defendant might be incompetent.” (People v.
    Rodrigues (1994) 
    8 Cal.4th 1060
    , 1112.)
    The court was by this point in the trial quite familiar with
    Bloom, who had addressed the court cogently and at length
    about sanity phase decisions. Against these opportunities for
    observation, defense counsel Applebaum cited no specific
    aspects of Bloom’s behavior or communications that prompted
    him to declare a doubt, nor did he intimate that in invoking
    Penal Code section 1368 he was relying on any new expert
    evaluations of his client. Dr. Vicary’s testimony, on which
    Bloom now relies, did not constitute an opinion that Bloom was
    presently incompetent or would necessarily become so. And to
    33
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the extent Bloom now relies on his subsequent decision to
    withdraw his insanity plea after the sanity phase mistrial, at
    the time Bloom gave a facially rational basis for his decision:
    that a retrial would require the case be transferred to a different
    department, with a different judge. While the insanity plea and
    trial may have highlighted tensions between Bloom and his
    attorneys, leading to Bloom absenting himself from that phase
    of trial, no competency hearing is required when a “defendant’s
    lack of cooperation” arises from unwillingness rather than
    inability. (People v. Lewis (2008) 
    43 Cal.4th 415
    , 526.) In sum,
    nothing in the sanity phase presented the court with substantial
    evidence of incompetence; in the absence of such evidence, we
    cannot conclude the trial court erred in allowing criminal
    proceedings to continue despite counsel’s stated doubts about
    the recent deterioration of Bloom’s mental state.
    B. Guilt Phase Issues
    1. Sixth Amendment right of autonomy over the
    defense
    Bloom willingly conceded that he killed Bloom, Sr. But
    before trial, Bloom repeatedly objected to his attorneys’ plan to
    concede Bloom also killed Josephine and Sandra, and to pursue
    a mental capacity defense as to all three killings. Despite
    Bloom’s objections, at trial defense counsel told the jury that
    Bloom killed the three victims, but argued Bloom’s mental state
    rendered those actions manslaughter, not first degree murder.
    Bloom argues that counsel’s concessions violated his Sixth
    Amendment right of autonomy over the defense under McCoy v.
    Louisiana, 
    supra,
     584 U.S. ___ [
    138 S.Ct. 1500
    ] (McCoy). We
    agree in part: counsel’s decision to concede Bloom killed
    Josephine and Sandra, despite Bloom’s insistence to the
    contrary, violated Bloom’s right to determine the objectives of
    34
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the defense and maintain complete innocence as to these counts.
    But we disagree as to the killing of Bloom, Sr., for which Bloom
    consistently accepted responsibility. Once Bloom agreed to
    admit he killed his father, how best to secure acquittal or
    conviction of a lesser offense was a tactical matter vested with
    counsel.
    Throughout pretrial proceedings, Bloom made known his
    discontent with both of his appointed attorneys, moving to
    substitute or relieve counsel numerous times under Marsden
    and Faretta.10 Bloom’s chief complaint was that he did not want
    to present a mental defense, but he also objected to his
    attorneys’ plan to concede guilt as part of this strategy. He
    repeatedly told the court that he would admit to fatally shooting
    his father. But he refused to admit to killing Josephine and
    Sandra. He took the view that the prosecution’s evidence was
    weak, and he preferred to put the prosecution to its proof.
    Bloom did not succeed in either relieving counsel or
    altering counsel’s strategy. During opening statement, lead
    defense counsel Applebaum told jurors: “The evidence . . . is
    going to show you that [Bloom] killed his father, he killed
    Josephine and he killed Sandy.” Counsel argued that the
    killings were manslaughters because Bloom acted in the heat of
    passion when killing his father, who was “a horrible excuse for
    a human being.” Bloom then “descended into the depths of
    madness” and killed Josephine and Sandra but was incapable of
    deliberate thought when he did so. Counsel argued: “We will
    prove to you [Bloom] committed manslaughters and he should
    be held responsible for what he did.” Returning to the same
    10
    Faretta v. California (1975) 
    422 U.S. 806
     (Faretta).
    35
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    theme, counsel told the jurors Bloom should not be convicted of
    murdering Josephine and Sandra because “the mental states
    required for murder are not there. [¶] Yes, he should be held
    responsible for killing them. He did it. Manslaughter, an
    intentional killing, he did it.”
    During closing argument, defense cocounsel Tonya Deetz
    again referenced Bloom’s responsibility for the killings, telling
    jurors, “You will find him guilty.” She went on, “You will find
    [Bloom] criminally responsible for three homicides. That is a
    fact. [¶] He killed three people. It is neither excused nor
    justified.” Deetz told jurors they could find Bloom “guilty of
    anything [they] want, Josephine and Sand[y] will still be dead.”
    “One issue you don’t have to fool around with is did he do it,
    didn’t he do it,” Deetz argued, because there was “[t]ons of direct
    evidence that he killed these people.”         Applebaum later
    reiterated, “He is guilty and you will find him guilty. The
    question is what is he guilty of. Murder or another type of
    homicide?” He also informed jurors that Bloom was “guilty of
    something,” and noted “in some ways that takes away from the
    presumption of innocence.” Finally, he urged the jury to
    conclude Bloom “is guilty of involuntary manslaughter as to
    Josephine and Sand[y] because of his mental illness, this
    dissociation.”
    Bloom claims that his attorneys violated his autonomy-
    based right to determine the objective of his defense, guaranteed
    by the Sixth Amendment to the United States Constitution, by
    conceding over his objection that he was responsible for killing
    Josephine and Sandra and by presenting a mental state defense
    to all three charged crimes. His argument relies on McCoy,
    supra, 
    138 S.Ct. 1500
    , which considered “whether it is
    unconstitutional to allow defense counsel to concede guilt over
    36
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the defendant’s intransigent and unambiguous objection” and
    answered that question in the affirmative. (Id. at p. 1507.)
    In McCoy, the defendant shot and killed his estranged
    wife’s mother, stepfather, and son in their home. (McCoy, 
    supra,
    138 S.Ct. at pp. 1505–1506.) McCoy was indicted on three
    counts of first degree murder but maintained he was not
    involved in the killings because he was out of state and the
    victims were instead killed by corrupt police officers following a
    drug deal. (Id. at p. 1506.) In light of “overwhelming” evidence
    tying his client to the murders, McCoy’s retained counsel, Larry
    English, decided the best strategy to avoid a death sentence was
    to concede McCoy’s guilt (ibid.) and appeal to the jury’s mercy
    in view of McCoy’s “ ‘serious mental and emotional issues’ ” (id.
    at p. 1507). McCoy, however, was “ ‘complet[ely] oppos[ed] to
    [his attorney] telling the jury that [he] was guilty of killing the
    three victims.’ ” (Id. at p. 1506.) Given English and McCoy’s
    differences concerning what strategy to pursue, McCoy sought
    to substitute counsel two days before trial. (Ibid.) The court
    denied that request and instructed English that it was his role
    to “ ‘make the trial decision’ ” about whether to concede his
    client’s guilt. (Ibid.) As he had indicated he would, English
    conceded McCoy’s guilt of the three murders during the guilt
    phase opening statement, telling jurors “there was ‘no way
    reasonably possible’ that they could hear the prosecution’s
    evidence and reach ‘any other conclusion than Robert McCoy
    was the cause of these individuals’ death[s].’ ” (Ibid.) The jury
    returned three death verdicts, and the Louisiana Supreme
    Court affirmed, concluding defense counsel had authority to
    concede guilt over the defendant’s opposition. (Id. at p. 1507.)
    The United States Supreme Court reversed, holding
    English’s concession violated McCoy’s right, grounded in the
    37
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Sixth Amendment, to “decide that the objective of the defense is
    to assert innocence.” (McCoy, 
    supra,
     138 S.Ct. at p. 1508.) The
    court distinguished for these purposes between the types of
    decisions that counsel ordinarily may make unilaterally and
    those defendants are entitled to make for themselves. The court
    explained:      “Trial management is the lawyer’s province:
    Counsel provides his or her assistance by making decisions such
    as ‘what arguments to pursue, what evidentiary objections to
    raise, and what agreements to conclude regarding the admission
    of evidence.’ [Citation.] Some decisions, however, are reserved
    for the client — notably, whether to plead guilty, waive the right
    to a jury trial, testify in one’s own behalf, and forgo an appeal.”
    (Ibid.) The court concluded that “[a]utonomy to decide that the
    objective of the defense is to assert innocence belongs in this
    latter category”: “Just as a defendant may steadfastly refuse to
    plead guilty in the face of overwhelming evidence against
    her, . . . so may she insist on maintaining her innocence at the
    guilt phase of a capital trial.” (Ibid.) Put differently: “When a
    client expressly asserts that the objective of ‘his defence’ is to
    maintain innocence of the charged criminal acts, his lawyer
    must abide by that objective and may not override it by
    conceding guilt.” (Id. at p. 1509.)
    Bloom argues this case is controlled by McCoy. We agree
    with respect to the counts arising from the deaths of Josephine
    and Sandra. Defense counsel conceded, over Bloom’s objection,
    both that Bloom killed Josephine and Sandra and that Bloom
    should be held criminally liable for the killings. Counsel’s
    decision to concede Bloom’s guilt on these counts cannot be
    squared with a rule that gives the criminal defendant the right
    to “oppos[e] . . . any admission of guilt” (McCoy, supra, 
    138 S.Ct. 38
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    at p. 1507) and instead “pursue acquittal” as the object of the
    representation (id. at p. 1506).
    It is true that counsel here argued Bloom should be held
    liable only for lesser offenses than the first degree murder
    charges he faced. Counsel undoubtedly had sound reasons for
    making these concessions; in view of the evidence, counsel may
    well have concluded the best possible outcome of the proceedings
    was one that would reduce the severity of Bloom’s likely
    punishment.       But even so, counsel’s concessions were
    incompatible with Bloom’s objective to instead maintain
    innocence and pursue acquittal. And as McCoy instructs, the
    decision about what objective to pursue was Bloom’s to make.
    Indeed, the McCoy opinion addressed this very scenario,
    citing with approval a number of state cases holding that
    counsel may not unilaterally pursue a strategy of “concession of
    the defendant’s commission of criminal acts and pursuit of
    diminished capacity, mental illness, or lack of premeditation
    defenses.” (McCoy, 
    supra,
     138 S.Ct. at p. 1510.)11 These cases,
    as the high court described them, “were not strategic disputes
    about whether to concede an element of a charged offense,
    [citation]; they were intractable disagreements about the
    fundamental objective of the defendant’s representation.”
    (McCoy, at p. 1510.) This was so because the unavoidable
    11
    For example, in People v. Bergerud (Colo. 2010) 
    223 P.3d 686
    , cited with approval by McCoy, 
    supra,
     138 S.Ct. at
    page 1510, the Colorado Supreme Court considered whether
    defense counsel had, “by focusing on [defendant’s] mental state,
    . . . effectively pled him guilty to lesser homicide crimes against
    his wishes,” conduct that in its view “would have overstepped
    their bounds and appropriated fundamental choices committed
    to the defendant’s decision alone.” (Bergerud, at p. 697.)
    39
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    consequence of counsel’s strategy in those cases was to abandon
    the defendant’s wish to pursue acquittal in favor of a strategy
    that would concede criminal responsibility of a lesser crime in
    order to seek lesser punishment. In characterizing this choice
    as going to the fundamental objective of the defendant’s
    representation, McCoy makes clear that the decision whether to
    concede the defendant should be found guilty of a crime — even
    a lesser crime than the one the prosecution charged — is a
    decision that necessarily belongs to the defendant. (See also
    People v. Flores (2019) 
    34 Cal.App.5th 270
    , 273, 275 [finding
    McCoy error where counsel conceded killing and argued absence
    of premeditation over the defendant’s objection];12 People v.
    Eddy (2019) 
    33 Cal.App.5th 472
    , 477 [finding McCoy error
    where counsel conceded guilt of manslaughter over client’s
    objection]; State v. Horn (La. 2018)

    , 1072–1074
    [finding McCoy error where counsel conceded capital defendant
    was guilty of second degree murder or manslaughter over
    defendant’s objection].)
    The Attorney General does not dispute that McCoy forbids
    counsel from conceding guilt of the charged offense or lesser
    included offenses despite the client’s wish to maintain
    innocence. He instead argues McCoy is inapplicable because the
    core of Bloom’s objection was not, in fact, a wish to maintain
    innocence, but instead a wish to avoid a mental capacity defense
    and a wish to test gaps in the prosecution’s evidence that he
    killed Josephine and Sandra. Given the nature of Bloom’s
    12
    This case raises no question about the application of the
    Sixth Amendment to other types of concessions falling short of
    a concession of guilt, such as concession of certain elements of a
    charged offense. (See People v. Flores, supra, 34 Cal.App.5th at
    pp. 280–283.) We express no views on the subject.
    40
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    objection, the Attorney General contends that counsel’s decision
    to concede guilt was the sort of strategic judgment that falls
    within counsel’s prerogative under McCoy.
    With regard to Josephine and Sandra, the record belies
    the premise of the argument: Bloom clearly objected to
    admitting responsibility for the two victims’ deaths. It is true
    that he was not always adamant on this point; in an initial
    Marsden hearing, for example, he seemed to suggest that he
    ought to be entitled to reduce his convictions from first degree
    murder because he did not premeditate the murders, without
    mentioning that he either believed himself to be innocent or that
    he wished for his counsel to maintain his innocence on retrial.
    But Bloom would later inform the court and counsel, in
    unmistakable terms, that he did not want to admit to killing
    Josephine or Sandra. He said: “[Defense counsel], over my
    objection and against my express wishes, is going to concede
    guilt in this case and I find that to be intolerable and
    outrageous.” Even considering these statements in the broader
    context of Bloom’s opposition to the mental defense strategy,
    there is nothing genuinely ambiguous about his expressed
    desire to maintain innocence in the deaths of Josephine and
    Sandra.13 Counsel nonetheless conceded that Bloom was
    factually responsible for the deaths of Josephine and Sandra,
    13
    The Attorney General notes that at the first trial, Bloom
    disputed that he killed Josephine, but did not dispute that he
    killed Sandra. The Attorney General does not suggest, however,
    that Bloom affirmatively admitted to killing Sandra. (Cf. People
    v. Bloom, 
    supra,
     48 Cal.3d at p. 1207 [Bloom testified at trial
    that he saw Sandra after shooting Bloom, Sr., pulled the trigger
    on the rifle, and “ ‘the next thing that happened’ was that he was
    arrested while walking”].)
    41
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    and while he did not commit first degree murder, he should still
    be held criminally liable for their deaths. This decision was
    certainly understandable as a matter of trial strategy. But
    under McCoy, Bloom’s clearly expressed objection should have
    controlled.
    We agree with the Attorney General, however, that there
    was no McCoy violation in connection with the Bloom, Sr.,
    murder charge, as to which Bloom conceded his responsibility.
    And although Bloom cursorily argues otherwise, counsel’s
    presentation of a mental capacity defense on this count, in the
    absence of a clearly objected-to admission of criminal liability,
    did not give rise to a Sixth Amendment violation. McCoy
    explained the point as follows: “If, after consultations with
    English concerning the management of the defense, McCoy
    disagreed with English’s proposal to concede McCoy committed
    three murders, it was not open to English to override McCoy’s
    objection. English could not interfere with McCoy’s telling the
    jury ‘I was not the murderer,’ although counsel could, if
    consistent with providing effective assistance, focus his own
    collaboration on urging that McCoy’s mental state weighed
    against conviction.” (McCoy, 
    supra,
     138 S.Ct. at p. 1509.) Here,
    the case was retried precisely because the Ninth Circuit found
    Bloom’s counsel at his first trial ineffective for failing to
    effectively develop a mental state defense. (Bloom v. Calderon,
    
    supra,
     132 F.3d at pp. 1271–1278.) The decision to pursue a
    defense strategy focused on the role Bloom’s mental health
    played in the crimes was strongly indicated, if not outright
    compelled, by the Ninth Circuit’s decision. So here, where
    Bloom did not contest his responsibility for killing his father,
    Bloom, Sr., at the retrial, counsel did not violate the Sixth
    Amendment by presenting a mental state defense to first degree
    42
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    murder, even though Bloom did not wish for counsel to present
    the defense.14
    Having found error as to two of the murder counts, we
    consider the appropriate remedy. In McCoy, the court reversed
    the judgment without an inquiry into harmlessness.                It
    concluded that the autonomy rights violated by counsel’s
    unilateral decision to concede his client’s guilt of first degree
    murder fell within that category of rights that are “so basic to a
    fair trial that their infraction can never be treated as harmless
    error.”     (Chapman v. California (1967) 
    386 U.S. 18
    , 23
    (Chapman).) The court likened the violation in the case to a
    violation of a defendant’s right of self-representation, explaining
    “ ‘[t]he right is either respected or denied; its deprivation cannot
    be harmless.’ ” (McCoy, 
    supra,
     138 S.Ct. at p. 1511.) Like the
    deprivation of that right, the court concluded counsel’s
    erroneous concession of guilt of first degree murder was a
    “structural” error that could be corrected only by holding a new
    trial. (Id. at p. 1512.) Bloom argues that here, too, the error is
    structural and requires us to reverse the judgment in its
    entirety.
    We agree that the McCoy error requires reversal of the
    affected counts and associated allegations but disagree that it
    14
    We note that the decision whether to present a mental
    capacity defense differs from the decision whether to present a
    defense of not guilty by reason of insanity. While a mental
    capacity defense may mitigate criminal culpability, an insanity
    defense could result in indefinite commitment to a mental
    institution. For this reason, under long-standing California law,
    a presently sane defendant must be permitted to make the
    decision whether to mount an insanity defense. (People v. Gauze
    (1975) 
    15 Cal.3d 709
    , 717–718.)
    43
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    requires reversing the judgment in its entirety. In McCoy, it
    made sense to reverse the judgment on all counts because the
    error affected the entire defense: McCoy wished to maintain his
    innocence of all three murder counts, and counsel conceded his
    guilt on all three counts. Here, by contrast, Bloom wished to
    maintain his innocence on only two of the three counts. As
    noted, throughout the proceedings, Bloom acknowledged that he
    shot his father to death and clearly told the court and counsel
    that he had no objection to saying so. There is no reasonable
    possibility that counsel’s erroneous concessions with respect to
    the other counts affected the jury’s consideration of the count
    concerning the murder of Bloom, Sr. There is, therefore, no
    reason why the jury’s verdict with respect to the murder of
    Bloom, Sr., should not stand. (See, e.g., People v. Reese (2017) 
    2 Cal.5th 660
    , 671.)
    By contrast, counsel’s decision to concede Bloom’s criminal
    responsibility for the deaths of Josephine and Sandra over
    Bloom’s objection is error of the sort that, as McCoy instructs,
    defies harmlessness review. As the McCoy court explained:
    “Such an admission blocks the defendant’s right to make the
    fundamental choices about his own defense. And the effects of
    the admission would be immeasurable, because a jury would
    almost certainly be swayed by a lawyer’s concession of his
    client’s guilt.” (McCoy, supra, 138 S.Ct. at p. 1511.) Bloom
    “must therefore be accorded a new trial” on the affected counts
    “without any need first to show prejudice.” (Ibid.)
    This conclusion requires us to reverse Bloom’s convictions
    on counts 2 and 3, concerning the murders of Josephine and
    Sandra, as well as the associated firearm- and weapon-use
    allegations. The reversal of two of the three charged murder
    convictions also requires us to reverse the jury’s true finding on
    44
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    the only special circumstance alleged here, multiple murder.
    And this, finally, requires us to reverse the death judgment,
    which cannot stand in the absence of a valid special
    circumstance finding. (See People v. Trujeque (2015) 
    61 Cal.4th 227
    , 253.)
    2. Admission of witnesses’ former testimony
    Witnesses Martin Medrano and Christine Waller testified
    at Bloom’s first trial but were unavailable on retrial. The trial
    court allowed the prosecution to introduce their former
    testimony under Evidence Code section 1291.15 Bloom contends
    this was error that violated both the Evidence Code and his
    federal constitutional rights. We reject the argument.
    In his testimony as read to the jury on retrial, Medrano
    testified that in April 1982, three or four days before the
    homicides, Bloom asked Medrano to get him a handgun, offering
    15
    Evidence Code section 1291 provides: “(a) Evidence of
    former testimony is not made inadmissible by the hearsay rule
    if the declarant is unavailable as a witness and: [¶] (1) The
    former testimony is offered against a person who offered it in
    evidence in his own behalf on the former occasion or against the
    successor in interest of such person; or [¶] (2) The party against
    whom the former testimony is offered was a party to the action
    or proceeding in which the testimony was given and had the
    right and opportunity to cross-examine the declarant with an
    interest and motive similar to that which he has at the hearing.
    [¶] (b) The admissibility of former testimony under this section
    is subject to the same limitations and objections as though the
    declarant were testifying at the hearing, except that former
    testimony offered under this section is not subject to: [¶]
    (1) Objections to the form of the question which were not made
    at the time the former testimony was given. [¶] (2) Objections
    based on competency or privilege which did not exist at the time
    the former testimony was given.”
    45
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    $1,200 and mentioning he had a contract to kill someone. A few
    days later, Bloom told Medrano he would read about the killing,
    but never produced any money to buy a gun. When Medrano
    heard about the crime, he did not immediately come forward
    because he was in violation of his parole. At the time of his
    testimony, he was in custody for armed robbery, but testified he
    had not been promised anything for his testimony.
    Waller was 14 years old in April 1982 and 16 when she
    testified at Bloom’s first trial. At the time of the killings, she
    had known Bloom for about two years. They had a close
    relationship, and he would often stay overnight at her house.
    Sometime in April, Bloom told her there had been an attempted
    break-in at Waller’s house and that he would stay at the home
    to protect the family. Two nights before the killings, Bloom told
    her to stay indoors, and she saw him outside the house carrying
    her brother’s rifle. On the day before the killings, Bloom was
    again staying at her house. When Waller went to wake him at
    5:00 the next morning, he was not in his room. Waller also
    testified to Bloom’s antagonistic relationship with his father,
    who was always angry at him, and his caring relationship with
    his stepsister Sandra.
    The defense sought to exclude this testimony from being
    presented in the retrial. The defense contended that the prior
    testimony was inadmissible under Evidence Code section 1291
    because Bloom had not had “the right and opportunity to cross-
    examine the declarant[s] with an interest and motive similar to
    that which” he now had at the retrial, as section 1291 requires.
    (Evid. Code, § 1291, subd. (a)(2).) He contended this was so for
    several reasons: Because his former counsel missed important
    points in their cross-examination of the two witnesses, failing to
    probe Medrano’s motivations to lie as well as Waller’s
    46
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    observations of Bloom’s mental illness and relationships with
    family members; because former counsel had been found
    constitutionally ineffective; and because Bloom was
    incompetent at the time of the first trial. To support this last
    point, counsel relied on evidence developed in federal habeas
    corpus proceedings, including a neurological assessment and jail
    records evidencing Bloom’s bizarre behavior, delusions and
    hallucinations, and a suicide attempt, as well as various expert
    reports. Dr. Hyman Weiland, who had testified at the first trial
    that Bloom was incompetent, reviewed the additional evidence
    and gave a declaration stating he adhered to his previously
    expressed views. Dr. William Vicary, who had testified at the
    first trial that Bloom was competent, declared he now believed
    Bloom had been incompetent at the first trial based on
    reviewing additional materials and interviewing Bloom again.
    Drs. Julian Kivowitz, David Lisak, and Donald Verin also
    submitted declarations agreeing that Bloom had not been
    competent during his previous trial. Based on this evidence,
    counsel argued that a retrospective competency hearing was
    needed to determine whether the prior testimony of Medrano
    and Waller was admissible. (See People v. Lightsey (2012)
    
    54 Cal.4th 668
    , 703–711 [discussing nature and feasibility of
    retrospective competency proceedings].)
    The prosecutor opposed the motion. She noted that when
    the Ninth Circuit found Bloom had received ineffective
    assistance of counsel at his first trial, the court did not fault
    former counsel’s handling of the lay witnesses, instead reserving
    its criticism for his investigation and presentation of the expert
    mental health witnesses. She also asserted that prior counsel
    may have had tactical reasons for handling the lay witnesses as
    he did, such as to avoid emphasizing that Medrano knew Bloom
    47
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    from jail. Agreeing with the prosecutor, the trial court declined
    to exclude the challenged testimony of Medrano and Waller.
    We affirm the relevant rulings. The possibility that
    current counsel would have cross-examined a witness
    differently or more searchingly does not, in itself, render the
    prior testimony inadmissible under Evidence Code section 1291.
    (People v. Zapien (1993) 
    4 Cal.4th 929
    , 975 [“As long as
    defendant was given the opportunity for effective cross-
    examination, the statutory requirements were satisfied; the
    admissibility of this evidence did not depend on whether
    defendant availed himself fully of that opportunity”].)
    It is true that former defense counsel’s ineffective
    assistance can, in some circumstances, be grounds for excluding
    an unavailable witness’s prior testimony on constitutional
    grounds. In past cases, we have looked to “the circumstances
    surrounding the prior testimony and how it was used in the
    subsequent trial[] to determine whether the evidence at issue is
    attributable to counsel’s ineffective assistance and whether its
    use denied the defendant a fair trial in the subsequent
    proceeding.” (People v. Ledesma (2006) 
    39 Cal.4th 641
    , 686–687;
    see also Crawford v. Washington (2004) 
    541 U.S. 36
    , 57 [for
    purposes of the confrontation clause, former testimony is
    admissible if the defendant had an adequate opportunity to
    examine the witness at the prior hearing], citing, inter alia,
    Mancusi v. Stubbs (1972) 
    408 U.S. 204
    , 215 [confrontation
    clause did not bar use of a witness’s prior testimony on retrial
    following reversal of a conviction for ineffective assistance of
    former counsel where the defense proffered no “new and
    significantly material line of cross-examination that was not at
    least touched upon in the first trial”].)
    48
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Here, however, Bloom makes no persuasive showing that
    the trial court should have excluded the Medrano and Waller
    testimony due to deficiencies in prior counsel’s cross-
    examination. As for Medrano, the prosecutor elicited on direct
    examination the facts of Medrano’s criminal record and heroin
    addiction and that he had been promised nothing for his
    testimony. Trial counsel then cross-examined him regarding
    the effects of his drug use and the reasons for his delay in
    reporting his encounters with Bloom. The cross-examination
    gave the jury ample basis to question Medrano’s veracity.
    Bloom’s argument that further cross-examination would have
    provided the jury with additional reasons to doubt his testimony
    is not sufficient reason to bar the introduction of Medrano’s
    testimony on retrial. (See People v. Carter (2005) 
    36 Cal.4th 1114
    , 1174 [as long as the defendant was given the opportunity
    for cross-examination, admission of preliminary hearing
    testimony under Evid. Code, § 1291 does not violate the
    confrontation clause “ ‘simply because the defendant did not
    conduct a particular form of cross-examination that in hindsight
    might have been more effective,’ ” quoting People v. Samayoa
    (1997) 
    15 Cal.4th 795
    , 851].) As for Waller, defense counsel
    elicited on cross-examination her belief that Bloom, Sr., bullied
    Bloom, her characterization of Bloom’s good relationships with
    Josephine and Sandra, her observations of Bloom, Sr., losing his
    temper at Bloom, and her recollection of Bloom’s demeanor on
    the night of the offenses. The suggestion that former trial
    counsel, if sufficiently prepared, could have elicited from this
    teenage witness further information significantly bearing on
    Bloom’s mental state at the time of the offenses is speculative at
    best. While it is always possible to conceive of additional
    questions that could have been asked, former trial counsel’s
    49
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    cross-examination of Medrano and Waller was not so deficient
    that fairness required excluding their former testimony at
    Bloom’s retrial.
    As noted, Bloom alternatively sought exclusion of the
    Medrano and Waller testimony based on information developed
    in his federal habeas corpus proceedings that suggested he was
    incompetent during his prior trial. He contends that because he
    was incompetent, he did not have the adequate opportunity to
    cross-examine the witnesses that the Constitution requires.
    Bloom’s argument relies on Stevenson v. Superior Court
    (1979) 
    91 Cal.App.3d 925
    , 929–931. There, the defendant was
    held to answer following a preliminary hearing. It was later
    determined that the defendant was incompetent at the time of
    the hearing. After the defendant was restored to competency, a
    second preliminary hearing was held. At that hearing, the
    prosecution presented, over defense objection, the prior
    testimony of the now-unavailable victim, and the defendant was
    again held to answer. (Id. at pp. 927–928.) The Court of Appeal
    ordered the information set aside for lack of supporting
    evidence. The court concluded the victim’s prior testimony was
    inadmissible because the defendant lacked an adequate
    opportunity to cross-examine the victim by reason of his
    incompetence during the initial preliminary hearing. (Id. at
    pp. 930–931.) Although the defendant had been represented by
    counsel at the time, the appellate court nonetheless declined to
    presume the incompetent defendant enjoyed a meaningful
    opportunity for cross-examination. (Id. at p. 930.)
    The Attorney General urges us not to follow Stevenson,
    contending that Bloom’s asserted incompetence at his first trial
    should not affect admissibility of the prior testimony unless it
    50
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    demonstrably impaired the defense cross-examination of the
    witnesses at the first trial. But we need not decide here whether
    to adopt the reasoning of Stevenson, since the premise of the
    holding in that case is absent: Unlike the defendant in
    Stevenson, Bloom was never found to be incompetent at the time
    the witnesses were examined at the first trial. As noted above,
    the issue of Bloom’s competency was raised and litigated at the
    first trial, and Bloom was found competent. The issue arose
    around the time of sentencing, after he had been granted self-
    representation under Faretta, 
    supra,
     
    422 U.S. 806
    . While
    preparing for his sentencing, Bloom stabbed a fellow jail inmate.
    The trial court revoked his self-representation status,
    reappointed counsel, and ordered psychiatric evaluations and a
    competency hearing before a jury, which found him competent.
    (People v. Bloom, 
    supra,
     48 Cal.3d at p. 1217.) The trial court
    then restored his self-representation status and sentenced him
    to death. In reversing Bloom’s conviction and sentence, the
    federal court did not address any questions relating to his
    competency. (See Bloom v. Calderon, 
    supra,
     
    132 F.3d 1267
    .)
    On appeal, Bloom contends this was error; he maintains
    that the court should have held a retrospective competency
    hearing before ruling on the admissibility of Medrano’s and
    Waller’s former testimony. We conclude that the trial court did
    not err. While Bloom did amass additional evidence to support
    his argument that he was incompetent at the first trial, the
    court could reasonably weigh the retrospective opinions of
    medical professionals — rendered some nine years after trial —
    against the contemporaneous opinions of the professionals who
    had taken the view that Bloom was competent. As our cases
    have explained, there are often substantial obstacles to holding
    retrospective competency hearings — at which the defendant
    51
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    bears the burden of proving incompetence — even in cases in
    which competence to stand trial is directly at issue. (See, e.g.,
    People v. Wycoff, supra, 12 Cal.5th at pp. 93–96.) Here, the trial
    court did not err in declining to hold a retrospective competency
    hearing for the limited purpose of determining whether to admit
    the prior testimony of two witnesses who were, as explained
    above, effectively examined at the first trial.16
    The trial court did not, in short, err in overruling Bloom’s
    evidentiary objection.
    3. Cross-examination of Dr. Watson
    Bloom contends the trial court violated his rights under
    the state and federal Constitutions by allowing cross-
    examination of the defense neuropsychological expert
    concerning Bloom’s behavior and demeanor in the courtroom.
    We are unpersuaded.
    The issue arose in the following context. Dr. Watson twice
    conducted neuropsychological testing of Bloom, first in 1993 and
    again from 1999 to 2000. Dr. Watson testified as to what the
    testing revealed about Bloom’s cognitive capacities, deficits, and
    functioning and how they may have affected the commission of
    the crimes. On cross-examination, over a defense objection,
    Dr. Watson acknowledged that his report stated Bloom
    appeared to meet one of the criteria (Category A) for Asperger
    Syndrome as detailed in the Diagnostic and Statistical Manual
    of Mental Disorders: “marked impairment in the use of multiple
    nonverbal behaviors such as eye to eye gaze, facial expression,
    16
    This is true regardless of whether the trial court was
    bound by, or simply considered, the outcome of the competency
    proceedings at the first trial.
    52
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    body postures, and gestures to regulate social interaction.” The
    prosecutor then asked, “Hypothetically, if the defendant were to
    sit in the courtroom and make good eye contact with his defense
    attorneys and their assistant, and to watch the witnesses
    testify, and to then talk to his attorney, and then go back to
    watching the witness testify, would that tend to not be part of
    the Criteria A?” Defense counsel objected that the question was
    an improper hypothetical and lacked foundation, but the
    prosecutor said she had been watching and “it is absolutely
    true,” and that her expert had been in the courtroom for three
    days and would testify it was true. The court noted it had
    “observed eye-to-eye contact” and “numerous facial
    expressions,” and concluded the question was therefore proper.
    Defense counsel moved for a mistrial, arguing that comment on
    communication between Bloom and his defense team violated
    the attorney-client privilege. The court denied the motion. The
    prosecutor resumed cross-examining Dr. Watson, asking,
    “Hypothetically, if the defendant is sitting next to the . . .
    woman that’s sitting next to him making eye contact, smiling,
    gesturing with his hands, nodding up and down, speaking to her,
    she is speaking back to him, does that tend to tell you that we
    haven’t met” the Asperger criterion? Dr. Watson conceded,
    “That would tend to argue against that.”
    Bloom contends that his demeanor during the guilt phase
    of trial was legally irrelevant and not a proper subject for cross-
    examination, since Dr. Watson had never diagnosed him with
    Asperger Syndrome, and Dr. Mills, who had, did not explicitly
    determine whether the disputed criterion applied. He contends
    the prosecutor’s questions were improper for the additional
    reason that testimony or comment about the demeanor and
    behavior of Bloom and defense counsel during their courtroom
    53
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    interactions invited improper speculation about privileged
    matters.
    The trial court did not abuse its discretion in permitting
    the questioning.        As a general matter, a nontestifying
    defendant’s courtroom demeanor in the guilt phase of a capital
    trial is legally irrelevant and the prosecutor may not comment
    on it. (People v. Heishman (1988) 
    45 Cal.3d 147
    , 197 [“In
    criminal trials of guilt, prosecutorial references to a
    nontestifying defendant’s demeanor or behavior in the
    courtroom have been held improper” on various grounds,
    including that “[c]onsideration of the defendant’s behavior or
    demeanor while off the stand violates the rule that criminal
    conduct cannot be inferred from bad character”].) But by
    offering expert opinion on Bloom’s neuropsychiatric condition,
    the defense put in issue aspects of his behavior that shed light
    on the existence of that condition. (See 
    ibid.
     [rejecting claim of
    error on the basis that the prosecutor’s references to the
    defendant’s demeanor were made during the penalty phase of a
    trial in which the defendant had placed his own character in
    issue].) Dr. Watson acknowledged stating in his report that
    Bloom appeared to meet a diagnostic criterion for Asperger
    Syndrome, and the prosecutor could properly probe the basis for
    that opinion. (People v. Hawthorne (2009) 
    46 Cal.4th 67
    , 93–
    94.)17 The challenged questioning did not implicate the concerns
    underlying the general rule against using a defendant’s
    courtroom demeanor as impermissible bad character evidence.
    17
    In reaching this limited conclusion here, we are not
    suggesting that the prosecution is free to comment on a
    defendant’s courtroom behavior or demeanor anytime the
    defense places a defendant’s mental state in issue.
    54
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Nor, in view of the absence of any revelation of the content of
    communications between Bloom and his defense team, did the
    questioning infringe the attorney-client privilege or violate his
    right to privacy.
    4. Prosecutorial misconduct
    Bloom asserts the prosecutor engaged in several instances
    of improper argument and cross-examination during the guilt
    phase. He argues these instances of misconduct violated his
    federal and state constitutional rights, as well as Penal Code
    section 1180, and require reversal of the judgment.
    “Prosecutorial misconduct requires reversal when it ‘so infect[s]
    a trial with unfairness [as to] create a denial of due process.
    [Citations.] Conduct by a prosecutor that does not reach that
    level nevertheless constitutes misconduct under state law, but
    only if it involves the use of deceptive or reprehensible methods
    to persuade the court or jury.’ ” (People v. Armstrong (2019) 
    6 Cal.5th 735
    , 795.) We find no reversible misconduct here.
    a. Use in opening statement of Bloom’s remarks in
    closing argument at his first trial
    Before trial, the prosecution asked the court to permit it
    to introduce Bloom’s penalty phase closing argument from his
    first trial, in which he described thinking about killing his father
    weeks before the murder occurred. The defense objected, citing
    Penal Code section 1180, which states that “[t]he granting of a
    new trial places the parties in the same position as if no trial
    had been had,” and “[a]ll the testimony must be produced anew.”
    (Pen. Code, § 1180.) Notwithstanding the objection, Judge Hoff
    ruled the prosecution could use excerpts from the closing
    argument. As discussed below, however, the parties dispute
    whether Judge Hoff’s admissibility ruling was limited to use in
    55
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    cross-examination of defense experts or included use in the
    prosecution’s case-in-chief. Prosecutor Samuels had made clear
    her desire to introduce Bloom’s closing argument in the
    prosecution’s case-in-chief, but the rest of the admissibility
    discussion focused on the use of the argument in cross-
    examination. Specifically, Samuels argued that precluding her
    from using the argument excerpts would hamper her ability to
    “properly cross-examine” experts. The court agreed, rhetorically
    asking how “a court [could] preclude another party from cross-
    examining a witness,” and noting that the impact of having
    Bloom’s prior statement read is “precisely why [the prosecutor]
    wants to use it, . . . and I think the law provides for it,” albeit
    with “some redaction.”
    Judge Hoff later recused himself and Judge Schempp took
    over the case. At a hearing shortly before trial, defense counsel
    asked Judge Schempp to admonish the prosecution “not to bring
    up in their opening statement any issues that are still
    contested,” including “the penalty argument from the first trial
    by Mr. Bloom.” The court stated: “She is certainly not going to
    get into that in the opening statement.” The prosecutor
    asserted, “It doesn’t matter, it’s not contested; it’s all been ruled
    on. Everything she’s mentioned has already been ruled on.”
    Defense counsel disagreed as to the scope of Judge Hoff’s prior
    ruling. The court responded, “I’m not going to hear any more of
    this. These things have all been ruled on and Ms. Samuels
    knows how to make a proper opening statement on what she
    expects to prove.”
    During her guilt-phase opening statement, the prosecutor
    explained that she would prove that “rather than being mentally
    deficient, the defendant in this case was capable of formulating
    and did formulate a rather sophisticated plan to kill his father.”
    56
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Without telling the jury the context in which Bloom made the
    statement, the prosecutor then quoted from Bloom’s closing
    penalty phase argument at the first trial, at which he
    represented himself and asked the jury to return a death
    verdict: “ ‘This man was going to die. Weeks before this, sure,
    thoughts went through my head, “I’m going to kill the old man,”
    sure. The difference is putting it into action. Eventually this
    man was going to die and eventually he was going to die by my
    hand. He just speeded up the results.’ ”
    Defense counsel did not object at the time. Six days later,
    however, in a hearing outside the presence of the jury, the
    parties addressed defense objections under Penal Code section
    1180 to the admissibility of other portions of the closing
    argument.     At that hearing, Judge Schempp expressed
    discomfort with the prosecutor’s having introduced Bloom’s
    argument to the jury in the earlier trial as if it were a party
    admission under Evidence Code section 1220. Judge Schempp
    ruled, however, that the prosecutor could use the argument in
    cross-examining psychiatric experts.
    On appeal, the parties dispute the scope of Judge Hoff’s
    admissibility ruling as it was rendered, and which Judge
    Shempp had declined to reconsider before trial. Bloom contends
    the ruling allowed use of his prior penalty argument only to
    probe the basis for the defense experts’ opinions when they
    testified, while the Attorney General asserts Judge Hoff’s ruling
    “appeared to contemplate the admission of appellant’s
    statements during the prosecution’s case in chief,” presumably
    as a party admission under Evidence Code section 1220.
    Assuming without deciding that the prosecutor’s use of
    Bloom’s admission in her opening statement was misconduct,
    57
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    we perceive no prejudice under any standard. The quote was
    brief, and the jury was instructed that the remarks of counsel
    are not evidence. Aside from the use of this quote, the record
    reflects overwhelming evidence that Bloom premeditated the
    killing of his father: Bloom spent the days leading up to the
    murder obtaining a gun, planning to stay at Waller’s home and
    fabricating a break-in at that home to do so, and telephoning his
    father to tell him, “You’re running my life now, but you won’t be
    for long.”
    b. Cross-examination of defense expert regarding
    informant statements; argument concerning
    their reliability
    Bloom contends the prosecutor engaged in misconduct
    when cross-examining defense expert Dr. Mark Mills with the
    testimony of two jailhouse informants and making a related
    argument to the jury. Dr. Mills testified on direct examination
    that Bloom dissociated during the offenses and suffered from
    brain damage and Asperger Syndrome. In preparing to testify,
    Dr. Mills had reviewed the 1982 preliminary hearing testimony
    of Rodney Catsiff and Mariano Alatorre to the effect that Bloom
    had told them about the crime, his reasons for committing
    murder, the weapon he used, and the number of times he
    stabbed Sandra. During federal habeas corpus proceedings,
    however, both these informants had recanted their testimony in
    whole or in part, and the prosecutor noted that her office’s
    policies would not permit her to call Catsiff and Alatorre as
    witnesses in the present trial. But because their testimony had
    been provided to Dr. Mills, the court ruled he could be
    questioned concerning his reliance on it.
    On cross-examination, Dr. Mills disclaimed reliance on
    the informants’ preliminary hearing testimony because of their
    58
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    later recantations. The prosecutor then asked questions
    apparently aimed at bolstering the credibility of the informants’
    preliminary hearing testimony. The prosecutor asked, for
    example, how Catsiff could have known how many times Sandra
    was stabbed unless Bloom had told him, and whether Catsiff’s
    having written notes of his conversation with Bloom suggested
    that he had in fact testified truthfully about it.
    Bloom argues that by engaging in this line of questioning,
    the prosecutor improperly sought to vouch for the truth of the
    later-recanted informant testimony. Moreover, he contends, the
    prosecutor reinforced these themes in her closing argument
    when she asked the jury rhetorically, “[D]o you think it is
    reasonable that the detective in this case took these jailhouse
    snitches, put them on the stand and they were lying?” The
    Attorney General, for his part, contends the prosecutor’s
    questions and argument complied with the trial court’s ruling
    that Dr. Mills could be cross-examined on the topic; that the rule
    against vouching was not implicated here because Catsiff and
    Alatorre were not witnesses in the retrial; and that in any event
    no improper vouching occurred because the prosecutor’s
    statements and inferences regarding their testimony were all
    based on matters of record.
    Bloom’s claim as to the prosecutor’s rhetorical question in
    closing is forfeited by his failure to make a contemporaneous
    objection. (People v. Hill (1998) 
    17 Cal.4th 800
    , 820.) But even
    if Bloom’s claims of error were all preserved for appeal, we
    conclude that neither the prosecutor’s questioning nor her
    argument constituted improper vouching. “The general rule is
    that improper vouching for the strength of the prosecution’s case
    ‘ “involves an attempt to bolster a witness by reference to facts
    outside the record,” ’ ” such as the prosecutor’s personal
    59
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    experience. (People v. Huggins (2006) 
    38 Cal.4th 175
    , 206.)
    Unlike our recent decision in People v. Rodriguez (2020) 
    9 Cal.5th 474
    , 481, in which we concluded that a prosecutor
    impermissibly vouched for testifying officers by asserting they
    “would not lie because each would not put his ‘entire career on
    the line’ or ‘at risk,’ ” here — as the Attorney General correctly
    observes — “[a]ll of the prosecutor’s questions to Dr. Mills were
    based on the record or on reasonable inferences that could be
    drawn from the record.” Nor do we find the prosecutor’s
    remarks during closing argument constitute improper vouching.
    In context, the rhetorical question about the witnesses lying was
    part of a broader theme — that to accept the defense theory
    about Bloom’s mental state, the jury would have to ignore
    significant evidence, as had the defense expert. Dr. Mills, the
    prosecutor argued, had “disregard[ed] what doesn’t fit into his
    diagnosis. Just that simple. The pile of stuff in this case that
    you have to ignore if you want to believe the defense just keeps
    getting bigger and bigger.” “It is not . . . misconduct to ask the
    jury to believe the prosecution’s version of events as drawn from
    the evidence.” (Huggins, at p. 207.)
    c. Cross-examination of defense experts and
    argument regarding mental states (Pen. Code,
    § 29)
    Bloom contends the prosecutor improperly asked defense
    experts to render an opinion on Bloom’s mental state during the
    crimes.
    Penal Code section 29 provides that “[i]n the guilt phase
    of a criminal action, any expert testifying about a defendant’s
    mental illness, mental disorder, or mental defect shall not
    testify as to whether the defendant had or did not have the
    required mental states . . . for the crimes charged. The question
    60
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    as to whether the defendant had or did not have the required
    mental states shall be decided by the trier of fact.” “[S]ections
    28 and 29 . . . exclude expert testimony regarding a defendant’s
    capacity to form a required mental state and expert testimony
    stating a conclusion that a defendant did or did not have a
    required mental state.” (People v. DeHoyos (2013) 
    57 Cal.4th 79
    ,
    117.)18 “On the other hand, . . . questions concerning how
    defendant could perform certain acts without intending to do
    them, and whether defendant’s actions indicated that he had
    impaired judgment, [are] not inappropriate.” (People v. Smithey
    (1999) 
    20 Cal.4th 936
    , 961.)
    Dr. Watson testified on direct examination concerning the
    results of neuropsychological testing he administered to Bloom,
    which in the expert’s view showed long-standing brain damage
    resulting in “generally severe” impairment affecting his ability
    to process information and emotional reactions, react to new
    situations, and make decisions and judgments in a considered
    manner.
    On cross-examination, the prosecutor probed matters
    Dr. Watson had mentioned in his report to determine whether
    he relied on them and if not, why not. These matters included
    Bloom’s statement to another expert that, after the crimes, he
    18
    Penal Code section 28, subdivision (a), provides:
    “Evidence of mental disease, mental defect, or mental disorder
    shall not be admitted to show or negate the capacity to form any
    mental state, including, but not limited to, purpose, intent,
    knowledge, premeditation, deliberation, or malice aforethought,
    with which the accused committed the act. Evidence of mental
    disease, mental defect, or mental disorder is admissible solely
    on the issue of whether or not the accused actually formed a
    required specific intent, premeditated, deliberated, or harbored
    malice aforethought, when a specific intent crime is charged.”
    61
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    attempted “to get rid of the evidence and leave a cold trail,” as
    well as the fact that Josephine had been killed with three
    gunshots to her head and Sandra by multiple stab wounds as
    well as a gunshot to the face. Of the planning evidence, the
    prosecutor asked Dr. Watson, “Doesn’t that reflect not only his
    ability to make that plan, but the fact that he in fact carried it
    out?” Of the three shots that killed Josephine, the prosecutor
    asked whether they “show that the defendant knew exactly
    what he was doing when he killed her, that he was intending to
    kill her,” eliciting Dr. Watson’s answer that “I think it probably
    does.” And of the mode of Sandra’s killing, presented in a
    hypothetical question, the prosecutor asked Dr. Watson,
    “Doctor, is this person trying to kill Sandra Hughes or not?” The
    prosecutor continued: “And what I’m asking you is: If every one
    of his behaviors starting weeks before the murder in the
    planning of the killings — weeks before the killings with
    planning and ending shortly after the murder almost finishing
    the plan, you are saying that the only part of that period where
    his mental impairments kicked in because of the emotional
    components is during that short period of time from when he
    first shot his father until when he finished killing Sandra?”
    Dr. Watson agreed.
    Contrary to Bloom’s arguments, none of this questioning
    violated the restrictions in Penal Code section 29. The
    prosecutor was entitled to test on cross-examination
    Dr. Watson’s opinion that brain damage precluded Bloom from
    forming and carrying out plans in a disruptive emotional
    situation, including by highlighting possible inconsistencies
    between this opinion and Bloom’s characterization of his own
    conduct in an interview with another expert, which the witness
    admittedly had considered in conducting his evaluation.
    62
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Moreover, during cross-examination, the prosecutor, without
    objection from defense counsel, gave Dr. Watson latitude to
    articulate what he believed the evidence showed about Bloom’s
    mental state, a line of inquiry the defense followed up on in
    redirect examination, thus minimizing any conceivable
    prejudice from how the prosecutor framed her questions. Bloom
    has not shown prejudicial misconduct in this regard.19
    d. Asserted Griffin error
    Griffin v. California (1965) 
    380 U.S. 609
     (Griffin) holds
    that the Fifth Amendment “forbids either comment by the
    prosecution on the accused’s silence or instructions by the court
    that such silence is evidence of guilt.” (Id. at p. 615.) Bloom
    contends the prosecutor improperly commented in various ways
    on his invocation of the right to be silent, resulting in a violation
    of the rule announced in Griffin.
    First, Dr. William Vicary, a defense expert witness who
    testified on direct that Bloom was likely to “snap” under
    19
    Defendant also contends the prosecutor’s questioning was
    at times rude, sarcastic, or disparaging, as when she alluded to
    neurological deficits and Asperger Syndrome “rearing their ugly
    heads” or to defendant’s being “too whacked-out to know what
    he was doing.” Although a prosecutor’s intemperate behavior
    violates the federal Constitution if it infects the trial with such
    unfairness as to make the conviction a denial of due process
    (People v. Samayoa, 
    supra,
     15 Cal.4th at p. 841), and
    prosecutorial conduct that does not render a criminal trial
    fundamentally unfair violates state law if it involves the use of
    deceptive or reprehensible methods as a means to persuade the
    court or the jury (People v. Penunuri (2018) 
    5 Cal.5th 126
    , 149),
    the complained-of comments were mild and too fleeting to have
    adversely affected the fairness of the proceedings. Nor, for the
    same reason, did they amount to a prejudicial state-law
    violation.
    63
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    stressful situations, acknowledged on cross-examination (over
    defense objection) that being on trial for murder and hearing the
    percipient and expert witnesses would be a stressful situation
    for Bloom, suggesting, according to Bloom, “that the jury could
    infer from the absence of conduct communicating appellant’s
    distress in the courtroom that he did not break down in stressful
    situations.” Bloom contends this questioning thus permitted the
    jury, improperly, “to infer facts about appellant’s mental state
    during the crime from” his lack of assertive courtroom conduct,
    which Bloom would apparently treat as silence for Griffin
    purposes. But the prosecutor’s question merely invited the
    jurors to make an inference from their observations of Bloom’s
    courtroom demeanor; it did not constitute comment on his
    failure to testify or any other conduct that could reasonably be
    interpreted as a refusal to speak about the charged crimes.
    Next, Bloom contends the prosecutor twice committed
    Griffin error during closing argument. In describing Bloom’s
    interaction with Bloom, Sr., in front of the Sancola Avenue
    residence, the prosecutor argued, “We will never know what
    they were talking about out there.” Then, in reviewing the
    evidence concerning Sandra’s murder, the prosecutor suggested
    that after inflicting nonfatal stab wounds on the young girl,
    Bloom retrieved a live round and shot her. “And that explains
    why he only shot her once and left her breathing because he just
    was having trouble with that gun and he managed to find a live
    round, whether it was in that room or he went into another
    room, but he loaded the gun again and he shot her in the face.
    [¶] Now, does he go into the kitchen to try to fix the gun so he
    can find another live round to shoot her again? Is that what he
    was doing at the kitchen window? We will never know that. It
    is certainly a reasonable interpretation of what was going on in
    64
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    that house that night.” Defense counsel objected to both sets of
    comments, citing Griffin, and moved for a mistrial. The court
    overruled the objection and denied the motion.
    We agree with the trial court in part and disagree in part.
    The prosecutor’s comment that “we will never know what
    [Bloom and his father] were talking about out there” in front of
    the Sancola Avenue residence, in a conversation as to which only
    Bloom evidently could have testified, appears impermissible
    under Griffin. While a prosecutor does not violate the Griffin
    rule by commenting on the absence of certain evidence, a Griffin
    error does occur when the only possible source of such evidence
    would have been the defendant. (See, e.g., People v. Johnson
    (1992) 
    3 Cal.4th 1183
    , 1229 [prosecutor errs by referring to
    evidence as “ ‘uncontradicted’ ” or “ ‘unrefuted’ ” only when the
    defendant, who elects not to testify, is the only person who could
    have refuted it].) The comment, however, was brief and did not
    overtly call attention to Bloom’s failure to take the stand at the
    guilt phase to explain what had occurred. We are satisfied
    beyond a reasonable doubt that the prosecutor’s fleeting remark
    could not have prejudiced Bloom. (Chapman, supra, 386 U.S. at
    pp. 25–26.) By contrast, the prosecutor’s statement that
    Bloom’s entering the kitchen of the Sancola Avenue residence
    during the crimes may have been part of a search for a live round
    to shoot at Sandra constituted fair comment on the evidence.
    The prosecutor cautioned jurors that “we will never know that,”
    while urging that it was “a reasonable interpretation” of the
    evidence. In context, the prosecutor was not drawing attention
    to the absence of direct testimony on the issue but advising the
    jury it was being asked to make an inference from the facts in
    evidence.
    65
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    e. Asserted reliance on facts not in evidence
    In her guilt phase closing argument, the prosecutor sought
    to persuade jurors against returning a voluntary manslaughter
    verdict by reminding them “there is some evidence in this case
    that [Bloom, Sr.,] wasn’t always a tyrant and there is some
    evidence in this case that he loved his son. You heard the
    telegrams . . . when [Bloom] was in the Navy and they were
    loving.” As Bloom points out, the telegrams to which the
    prosecutor referred, sent by Bloom, Sr., to Bloom during the
    latter’s brief stint in the Navy, were not admitted into evidence.
    Rather, the prosecutor called Bloom’s mother, Melanie, to testify
    in rebuttal about language in the telegrams that expressed love
    for Bloom, contrary to Melanie’s earlier testimony that she had
    never heard Bloom, Sr., do so.
    The argument may well have been improper. The court
    allowed the prosecutor to question Melanie about the telegrams
    only in order to impeach her prior testimony that she had never
    heard Bloom, Sr., express love to Bloom, not as positive evidence
    that Bloom, Sr., had expressed love for Bloom. On the latter
    point, Melanie’s testimony about the telegrams was hearsay for
    which the Attorney General posits no exception.              The
    prosecutor’s misuse of the testimony in argument did not render
    Bloom’s trial unfair but could be characterized as deceptive, or
    at least misleading, conduct. We see no conceivable prejudice
    from the error, however, whether considered individually or in
    combination with the other asserted instances of prosecutorial
    misconduct.
    66
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    5. Instructional error
    a. Conduct evidencing guilt
    Bloom contends the trial court erred in instructing the
    jury with CALJIC Nos. 2.06 and 2.52, concerning suppression of
    evidence and flight, respectively, as demonstrating
    consciousness of guilt. He argues they were unnecessary,
    misleading, and argumentative, allowed the jury to draw
    irrational inferences against him, and denied him his Sixth,
    Eighth, and Fourteenth Amendment rights to due process, a fair
    trial, a jury trial, equal protection, and reliable jury
    determinations of guilt and special circumstances.
    As Bloom acknowledges, we have previously rejected these
    contentions (e.g., People v. Streeter (2012) 
    54 Cal.4th 205
    , 253–
    254 [CALJIC No. 2.52]; People v. Dement (2011) 
    53 Cal.4th 1
    ,
    52–53 [CALJIC No. 2.06]), and he advances no persuasive
    reason why we should reconsider our conclusions.
    b. Instructions assertedly undermining
    requirement of proof beyond reasonable doubt
    Bloom contends the trial court erred in reading the jury a
    series of instructions on the consideration of circumstantial and
    other evidence (CALJIC Nos. 2.01, 2.02, 2.21.2, 2.22, 2.27, and
    8.20), which he contends diluted the reasonable doubt standard.
    Contrary to Bloom’s claims, and as we have previously held,
    CALJIC Nos. 2.01 and 2.02 did not direct the jury to convict him
    of murder if he “ ‘reasonably appeared’ ” guilty, even if jurors
    still entertained a reasonable doubt of his guilt (People v.
    Nakahara (2003) 
    30 Cal.4th 705
    , 714), and CALJIC Nos. 2.21.2,
    2.22, 2.27, and 8.20 did not urge the jury to decide material
    issues by determining which side had presented relatively
    stronger evidence (People v. Casares (2016) 
    62 Cal.4th 808
    , 831–
    67
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    832). “Because defendant advances no persuasive reason to
    depart from our precedents, we adhere to them here.” (Id. at
    p. 831.)
    C. Sanity Phase Issues
    1. Refusal to allow Bloom to represent himself at the
    sanity phase
    As explained above, Bloom argues that the trial court
    erred in failing to suspend proceedings to adjudicate his
    competency during the sanity phase, an argument we have
    rejected. (See ante, pt. II.A.2.c.) Bloom argues in the alternative
    that the court should have permitted him to represent himself
    in that portion of the trial. We reject that contention as well.
    Bloom advised the court he wished to represent himself for
    the sanity phase after the jury had been instructed and just
    before closing arguments in the guilt phase. As the reason for
    his request, he referred to the court’s decision to instruct the
    jury on voluntary manslaughter only as to the charge relating
    to Bloom, Sr. He also mentioned there was an unspecified issue
    relating to penalty that, if resolved as he preferred, would cause
    him to withdraw his request to represent himself in the sanity
    phase. Bloom acknowledged his lack of familiarity with the
    intricacies of the applicable law while nevertheless expressing
    confidence that he could handle the trial of the sanity phase.
    Referring to prosecutor Samuels’s previous comment that she
    had never conducted a sanity trial, Bloom commented, “So we
    can just do it for the first time together.” The court declined to
    rule at that time.
    The court revisited the issue five days later during the
    jury’s guilt deliberations. After confirming that Bloom still
    wished to represent himself, the court denied the request.
    68
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Preliminarily, the court observed that the request was untimely,
    having been made after the start of trial, and it therefore had
    discretion whether to grant the request. The court cited two
    bases for denial: the complexity of the case and the likelihood
    the proceedings would be disrupted by delays, given the
    difficulties Bloom would encounter in trying to schedule
    psychiatric expert witnesses from jail. That prosecutor Samuels
    had never previously conducted a sanity trial was not, the court
    noted, a good reason for Bloom to represent himself. The court
    also expressed concern that allowing Bloom to represent himself
    might lead the jury to assume the court believed Bloom
    “competent and competent enough to represent [himself] at a
    very serious stage in the trial.”
    As Bloom acknowledges, People v. Windham (1977)
    
    19 Cal.3d 121
     (Windham) holds that to invoke the unconditional
    Sixth Amendment right to self-representation recognized in
    Faretta, 
    supra,
     
    422 U.S. 806
    , a defendant must do so “within a
    reasonable time prior to the commencement of trial.”
    (Windham, at p. 128.) Bloom argues that nothing in Faretta
    supports such a limitation, and even a belated request must be
    granted unless it would entail undue delay or interfere with the
    orderly administration of justice.
    The argument is without merit. Faretta itself recognized
    a constitutional right to self-representation in the context of a
    request made “weeks before trial.” (Faretta, 
    supra,
     422 U.S. at
    p. 835.) In the years since, this court and others have concluded
    that that right is not absolute if not exercised until the eve of, or
    after the onset of, trial. (People v. Wright (2021) 
    12 Cal.5th 419
    ,
    440 [collecting cases]; see, e.g., U.S. v. Tucker (10th Cir. 2006)

    Cir. 1991)

    69
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    Appeal of Cal., Fourth Appellate Dist. (2000) 
    528 U.S. 152
    , 162
    [noting that “most courts” require that Faretta rights be
    exercised in a timely manner].) We adhere to our previously
    expressed view that an untimely Faretta request is a matter
    entrusted to the court’s discretion. In evaluating an untimely
    motion, a court may consider not only “the potential for delay
    and disruption” but also “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.” (People v. Buenrostro (2018) 
    6 Cal.5th 367
    , 426.)
    We see no abuse of discretion in the court’s declining to
    permit Bloom to represent himself in the sanity phase. The
    court properly considered the possibility of unintended delay
    resulting from difficulties Bloom might encounter in attempting
    to schedule his expert witnesses from jail. Any such delay had
    the obvious potential to negatively affect trial administration,
    as two jurors had commitments that restricted their future
    availability. Given the complexity of a sanity phase trial in a
    capital case, the trial court could also reasonably find a real risk
    of delay from problems Bloom might have producing and
    organizing the defense evidence. Nor was the court required to
    spontaneously offer suggestions regarding potential ways to
    mitigate this risk.
    Bloom argues the trial court abused its discretion by not
    “inquir[ing] sua sponte into the specific factors underlying the
    request thereby ensuring a meaningful record in the event that
    appellate review is later required.” (Windham, supra, 19 Cal.3d
    at p. 128.) But while such an inquiry may be helpful to create
    an adequate record for our review (see ibid.), we conclude the
    70
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    record here is sufficient to find the trial court’s denial of Bloom’s
    Faretta request was not an abuse of its discretion. As noted, one
    of the reasons the court cited — the complexity of the case and
    the attendant risk of delay — finds support in the record and
    affords a sound basis for the court’s exercise of discretion in
    denying Bloom’s Faretta request. Consequently, we need not
    address the validity of the other reason the court mentioned in
    making its ruling, its concern over inferences the jury might
    draw about the court’s view of Bloom’s competence.
    2. Allowing Bloom to absent himself
    Bloom contends the trial court erred under Penal Code
    sections 977 and 1043, which generally call for the defendant’s
    presence at a trial on felony charges, and violated his state and
    federal constitutional rights to confrontation and due process,
    by allowing him to absent himself during the taking of evidence
    in the sanity phase and failing to ensure that his purported
    waiver of presence was knowing and intelligent. (U.S. Const.,
    5th, 6th, & 14th Amends.; Cal. Const., art. I, §§ 7, 15; Johnson
    v. Zerbst (1938) 
    304 U.S. 458
    , 464 [waiver standard].) We find
    no prejudicial error.
    On the first day of the sanity phase, defense counsel
    informed the court that Bloom did not want to be present.
    Outside the presence of the jury, the court informed Bloom he
    had a right to be present and asked him what he wished to do.
    Bloom replied that he did not want to be present to hear the
    testimony in the sanity phase, though he wanted to be present
    for the reading of the verdict. In Bloom’s absence, the court told
    the jury that “Mr. Bloom has chosen not to be present during
    this second phase of the sanity proceedings which he has a right
    to make that choice.”
    71
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    After evidence was presented and both sides rested in the
    sanity trial, the court asked if Bloom wished to be present;
    defense counsel indicated that Bloom wanted to be present when
    the verdicts were read and also wished to be brought into court
    to address his Faretta motion while the jury was deliberating.
    After the jury had begun deliberating, Bloom was brought into
    the courtroom and was present for the ensuing proceedings.
    Penal Code section 1043 provides in relevant part that the
    defendant need not be present at trial in a felony case if the
    defendant persists in disrupting the trial and in “[a]ny
    prosecution for an offense which is not punishable by death in
    which the defendant is voluntarily absent.” (Id., subd. (b)(2).)
    We have held that Penal Code sections 977 and 1043, read
    together, preclude a nondisruptive capital defendant from
    waiving his or her presence during the taking of evidence before
    the trier of fact. (People v. Weaver (2001) 
    26 Cal.4th 876
    , 967–
    968.) Proceeding with the sanity trial in Bloom’s absence was,
    therefore, error under state law (People v. Young (2005)
    
    34 Cal.4th 1149
    , 1214), a point the Attorney General does not
    contest. Bloom argues this state law error was prejudicial under
    People v. Watson (1956) 
    46 Cal.2d 818
    , 836, because the jury
    deliberated at length before reaching its verdict on sanity on
    count 1 and was deadlocked on counts 2 and 3. But nothing in
    his argument, or in the record, suggests it is “reasonably
    probable that a result more favorable” (ibid.) to Bloom would
    have occurred had he been present during the presentation of
    sanity-phase evidence (see People v. Mendoza (2016) 
    62 Cal.4th 856
    , 902–903 [absence of capital defendant during receipt of
    evidence held harmless under the reasonable probability
    standard]).
    72
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    A criminal defendant also has the right, under the Sixth
    Amendment’s confrontation clause and under the due process
    guarantee of the Fifth and Fourteenth Amendments, “to be
    present at any stage of the criminal proceeding that is critical to
    its outcome if his presence would contribute to the fairness of
    the procedure.” (Kentucky v. Stincer (1987) 
    482 U.S. 730
    , 745;
    People v. Jackson (1996) 
    13 Cal.4th 1164
    , 1209.) But a
    defendant may waive his or her federal constitutional right of
    presence, provided the waiver is voluntary, knowing, and
    intelligent. (Johnson v. Zerbst, 
    supra,
     304 U.S. at p. 464.)
    Bloom contends the trial court failed to ensure that his
    waiver met the constitutional standard by not adequately
    ensuring he understood the importance of the sanity phase and
    not inquiring into his reasons for absenting himself. He
    contends the record reflects he based his decision to absent
    himself from the sanity phase on an erroneous understanding of
    the significance of the sanity proceedings with respect to his
    death eligibility.
    We see no constitutional deficiency in the waiver
    procedure employed here. We have not required that a trial
    court question the defendant regarding why he wishes to absent
    himself or admonish him concerning the importance of his
    decision. (People v. Weaver, 
    supra,
     26 Cal.4th at p. 967.) Here,
    as in Weaver, “[d]efendant was represented by counsel, and he
    himself chose, for his own reasons, to leave the courtroom.”
    (Ibid.) To the extent Bloom argues the court’s inquiry was
    “minimal” or “perfunctory,” we note that even brief colloquies
    during which the trial court simply confirms a defendant’s wish
    to waive his presence (People v. Moon (2005) 
    37 Cal.4th 1
    , 20–
    21) or informs him of his right to be present (People v. Young,
    73
    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    supra, 34 Cal.4th at pp. 1212–1213) have been deemed, as we
    deem this one, constitutionally adequate.
    Bloom contends his choice to absent himself was
    influenced by a mistaken belief that the case would proceed to a
    penalty phase regardless of the outcome of the sanity phase,
    given the court’s affirmative response to his earlier inquiry
    whether “the [guilt] verdicts by this jury trigger a penalty
    phase.” But when the court responded in this manner, the jury
    had just reached its guilt verdicts and whether there would even
    be a sanity phase was uncertain. In the ensuing discussion,
    Bloom made clear that although he had not changed his mind
    regarding the dubious validity of the mental defense, the jury’s
    rejection of first degree murder verdicts on counts 2 and 3 had
    convinced him to proceed with the sanity phase. He told the
    court: “I am not going to speak to you as a defendant right now,
    I am going to speak to you as a convict, okay? [¶] We always
    look for a way out, okay? And if I got a way out, I am going to
    take it. [¶] So let’s go ahead and have the sanity phase, but let’s
    be very clear about something. . . . [¶] So me having the sanity
    phase, I am not changing my mind on that. I am just saying
    that maybe I have a way out so I am going to take it.” Bloom
    thus seemed to understand that if the jury were to find him not
    guilty by reason of insanity, he would be spared a death
    sentence, and for that reason he chose to go forward with the
    sanity phase. His decision to absent himself from it was not
    predicated on a mistaken belief that the outcome was of no
    consequence to the penalty he faced.
    We conclude the trial court’s acceptance of Bloom’s
    decision to absent himself did not deprive Bloom of his federal
    constitutional rights.

    PEOPLE v. BLOOM
    Opinion of the Court by Kruger, J.
    D. Cumulative Error
    As explained above, we conclude that a violation of the
    rule of McCoy, 
    supra,
     
    138 S.Ct. 1500
    , requires the reversal of
    Bloom’s two second degree murder convictions and associated
    enhancement and special circumstance findings.               Bloom
    contends that even if no other error in his trial was so prejudicial
    that it separately warrants relief, the combined impact of other
    errors requires reversal of the judgment in its entirety. We have
    found or assumed the prosecutor engaged in misconduct (1) in
    her guilt phase opening statement, when she quoted from
    Bloom’s argument to the jury in the prior trial, and (2) during
    her guilt phase closing argument, when she made comments
    that may have called the jury’s attention to Bloom’s failure to
    testify and that invited the jury to consider for its truth
    testimony that had been admitted for a nonhearsay purpose
    only. We have also found the trial court erred in permitting
    Bloom to absent himself from the sanity trial. In each such
    instance, we concluded prejudice was lacking. Now, considering
    the cumulative effect of all these errors, we reach the same
    conclusion. We accordingly reject Bloom’s argument that the
    errors, taken together, require us to reverse the judgment in its
    entirety.
    III. DISPOSITION
    We reverse the convictions for second degree murder on
    counts 2 and 3 and the associated firearm-use and weapon-use
    findings, as well as the multiple-murder special-circumstance
    finding and the judgment of death. We affirm the judgment in
    all other respects.
