    PEOPLE v. CARO
    S106274
    Opinion of the Court by Cuéllar, J.
    In April 2002, defendant Socorro Susan Caro was
    sentenced to death for killing three of her four children. This is
    her automatic appeal. We affirm the judgment below.
    I.    BACKGROUND
    Caro and her husband, Dr. Xavier Caro (Xavier1), had four
    children: Xavier (known as “Joey”), Michael, Christopher, and
    G.C. On November 22, 1999, Joey, Michael, and Christopher
    were shot to death in the family home in Camarillo, California.
    Joey was 11, Michael was 8, Christopher was 5, and G.C. was 1.
    The Ventura County District Attorney filed a felony complaint
    against Caro on December 17, 1999, and an information on April
    24, 2000. Caro was charged with three counts of murder (Pen.
    Code, § 187, subd. (a))2 while personally using a firearm
    (§ 12022.53, subd. (d)), and a multiple-murder special
    circumstance (§ 190.2, subd. (a)(3)). Caro pleaded not guilty,
    and not guilty by reason of insanity.
    At trial, the prosecution presented the testimony of Caro’s
    husband. Xavier met Caro in 1979 during her externship in his
    rheumatology medical practice. They began dating in 1980 and

    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    married in 1986. At the time of the shootings, Caro’s parents
    lived in the couple’s nearby second home and Caro’s mother,
    Juanita, would often stay over to help with the children.
    Early on in their relationship, Caro began working as
    Xavier’s office manager. In August 1999, Xavier fired Caro
    because, according to Xavier, she had been providing more
    money than expected to her parents while allowing the medical
    office’s rent to go unpaid. Xavier had also been having an affair
    with someone who worked in his office. Xavier and Caro had
    discussed divorce at various points in their relationship, and
    after firing Caro, Xavier consulted a divorce lawyer. Xavier
    testified he did not actually want a divorce. Indeed, Xavier
    thought their marriage had improved after Caro and he agreed
    in August 1999 to go to counseling, and Caro agreed to take
    Prozac.
    On the night of the shootings, November 22, 1999, Xavier
    returned from work between 6:00 and 6:30 p.m. Xavier had
    dinner with Caro, and they drank margaritas. Joey made a
    negative comment about his parents’ drinking. Xavier and Caro
    argued: Xavier wanted to discipline Joey, but Caro did not.
    Later, after Xavier removed the television and videogame
    system from Joey’s room as punishment, Xavier and Caro
    continued their argument. Caro accused Xavier of not loving
    her, and not respecting her. Xavier said he was leaving. Caro
    grabbed him by the shoulders, slid to the floor, and held his
    ankles as he pulled away from her. Juanita came up the stairs
    and yelled, “Get out, you brute.” Xavier entered the garage, got
    in his 1989 maroon Mercedes, and drove away.
    Juanita’s testimony about the end of the fight that evening
    was similar, though she testified that Xavier kicked Caro “on
    2
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    the legs” when Caro was on the ground. Juanita told police that
    after Xavier left, Caro said, “Now, Mom. I have no money now.
    I don’t know what I’m going to do,” and “Mom, we’re going to
    starve now.” Caro also told Juanita that night, “Well, I guess
    I’m crazy like he says I am” and “Mom, he says I’m crazy.”
    Around 9:00 p.m., Juanita left the house to return to her home.
    Caro seemed normal. Juanita returned a few minutes later
    because she forgot her glasses and left again soon after.
    Xavier testified that he drove to his office in Northridge,
    which was 40 to 46 minutes away from the house. Caro called
    Xavier multiple times on his car phone and at the office. When
    Xavier answered the phone at the office, Caro was crying and
    agitated and asked Xavier to come home. Caro then calmly
    stated, “That’s the thing I’ve always admired about you, X. You
    always know the difference between right and wrong.” Phone
    records show that Xavier made an unanswered call home at 9:53
    p.m. from the office. Xavier testified that he left the office
    around 10:30 p.m. to return home. As he left the building,
    Xavier saw a big white truck parked outside the gate, a truck
    that, according to the guard records, entered the hospital at
    10:25 p.m. Time-stamped videotapes from security cameras at
    Xavier’s work showed a vehicle similar to Xavier’s car arriving
    at 9:24 p.m. and leaving at 10:36 p.m.
    When Xavier returned home, he found Caro lying on her
    right side in a semifetal position on the floor of their master
    bedroom. Xavier noticed a bloodstained froth around her mouth
    and thought she had overdosed. Xavier called 911 from a phone
    in the bedroom at 11:21 p.m. He told the operator that Caro
    might have overdosed or slit her wrists. Xavier rolled Caro onto
    her back and noticed a .38-caliber revolver underneath Caro,
    and several expended shell casings. Xavier had previously
    3
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    purchased the gun for Caro, along with a gun for himself, for
    self-defense. Xavier picked up the gun and saw a single shell
    casing in the five-round cylinder.
    The 911 operator asked if there were any children in the
    house. Xavier went to Joey’s bedroom and found him lying face
    up covered in blood. Xavier checked for a pulse but found none.
    He then entered Michael and Christopher’s room and saw them
    lying together in the bottom bunk of the bunk bed. Their faces
    were ashen and neither boy was breathing. Xavier returned to
    the master bedroom and told the 911 operator that his children
    had been shot. Xavier kicked Caro and yelled at her.
    The 911 operator asked how many children were in the
    home. Xavier went to G.C.’s crib, found G.C. unharmed, and
    told the 911 operator, “We’ve got one alive here.” Xavier picked
    up G.C. and went to check the other children again. Joey and
    Christopher were not breathing, but Michael was taking deep
    gasping breaths. Xavier attempted to perform CPR on Michael,
    until a fragment of Michael’s skull came off in his hands. Xavier
    ran out of the room and told the 911 operator that first
    responders needed to get there fast. He called Juanita on a
    second phone line at 11:26 p.m. and told her that Caro “shot the
    babies.” Xavier went to the front door where he encountered two
    Ventura County Sheriff’s deputies, who ordered him outside.
    Xavier had G.C. in his arms and was distraught.
    When officers found Caro in the master bedroom, she was
    surrounded by several pools of blood, a pool of vomit, and
    expended shell casings. Caro was airlifted to a hospital.
    Meanwhile, back at the family’s home, Juanita had arrived. In
    a conversation between Xavier and Juanita that an officer
    recorded, Xavier alternated between a calm and visibly upset
    4
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    demeanor. He stated: “Why did she do this?”; “She killed my
    best friend. She killed my Joey”; and “She wasn’t messing
    around. She shot them all in the head.”
    Xavier testified that he always kept the guns in a gun safe,
    and Caro did not have the combination. In 1994 or 1995,
    following an argument, Xavier came home to find Caro holding
    a gun at the top of the stairs in the house. Xavier grabbed Joey
    and left, but came back when Caro called and said she would
    leave the gun in plain view for Xavier to recover.
    Caro underwent surgery on the night of the shootings for
    a gunshot to the head. Caro also had bruising on her right bicep,
    bruising on the inside of her thighs, and a fractured foot that
    was swollen and bruised. The forepart of the foot had broken
    away from the middle part of the foot and was repaired
    surgically a week later. Such an injury most commonly occurs
    by landing on a pointed foot so that the foot is twisted, which
    can happen when falling down stairs. The injury may also occur
    from a person falling on his or her foot with the person’s own
    weight, or if someone else stands on the foot as the person falls.
    The day after the shootings, Detective Cheryl Wade went
    to Caro’s hospital room and recorded the entire two-and-a-half
    to three-hour visit. Wade asked Caro if she had taken a fall, and
    Caro said she was not sure and could not remember. Caro said
    at one point that she “might have fallen down the stairs,” and
    that she was bruised by “wrestling with a boy.” But she
    reiterated on multiple occasions that she did not remember how
    she had been hurt. A defense expert enhanced the audiotape
    and believed Caro said, “You have to ask the boys” rather than
    “wrestling with the boys.”
    5
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Detective Wade told Caro that her boys had been hurt,
    that they had died, and that Caro was a suspect. Caro began
    crying and screaming. Caro asked what Xavier had said and
    asked where G.C. was located and whether he was okay.
    Detective Wade later brought Juanita into Caro’s room and
    recorded Juanita’s conversation with Caro. Caro said that “X is
    going to need somebody.” Juanita asked, “Why did you do this?”
    Caro replied, “My babies. My babies. I’m sorry. I’m sorry.”
    Lisa VanEssen worked at Xavier’s office. She testified
    that Caro had previously said she did not think Xavier loved her
    and was worried that Xavier would leave her and the boys with
    nothing. Around September 1999, VanEssen asked Caro how
    she was and Caro replied, “Not good. Sometimes I think it would
    just be better if I wasn’t here.” When VanEssen reminded Caro
    of her “four boys that need [her],” Caro replied, “What would it
    matter?”
    Investigators found a gun safe in Caro and Xavier’s master
    bedroom closet; the safe showed pry marks that could not be
    dated. The door to the gun safe could be opened without
    entering a combination. There were no testable fingerprints on
    the gun, but the gun was also stained, so it was unlikely the gun
    had been wiped down. Caro and Xavier both had gunshot
    residue on their right hands, but only swabs of Caro’s hands
    showed blood. At some point in the night, Xavier rinsed his
    hands without using soap.
    In the master bedroom, investigators found bullet
    fragments or evidence of bullet fragments on the floor, on the
    bed, in the wall above the bed, and in the ceiling. A forensic
    scientist opined that the wall and ceiling damage was consistent
    with the gun being held to the side of Caro’s head, and fired in
    6
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    an upward direction. The doctor who performed surgery on Caro
    on the night of the shootings confirmed that the bullet had
    traveled “upward on the side of the defendant’s head.”
    Investigators found two bloody handprints on the
    doorjamb between Joey’s bedroom and the bathroom that
    matched Caro’s hand, and blood above one of the handprints
    matched Joey’s blood. Stains on the pajama shorts and T-shirt
    Caro was wearing tested positive for blood. DNA testing
    matched some of the stains to Joey, some to Christopher, and
    some to Caro. According to a forensic scientist, projected blood
    caused some of the stains on Caro’s shorts. He opined that one
    of the stains on Caro’s shorts contained Christopher’s brain
    matter, and a piece of Joey’s scalp may have caused one of the
    other stains. Two blood stains in the master bathroom
    contained Joey’s blood, one of those stains had potential
    contributions from Christopher.        Material under Caro’s
    fingernails tested positive for blood and contained DNA from
    Caro, Joey, and Christopher.
    Various blood stains were found on Xavier’s sweatpants,
    shirt, and jacket. Blood stains on Xavier’s sweatpants, G.C.’s
    socks, the carpet, and the stair railing matched Michael’s DNA.
    Most were transfer stains, but drops of blood caused stains on
    Xavier’s sandals and on the knee of his sweatpants.
    Based on blood spatter patterns, Rod Englert, a crime
    scene reconstructionist, opined that Joey was facedown in bed
    when shot. He testified that Michael was face up when shot.
    Christopher, who was sleeping next to Michael, sat up and was
    shot twice, as the first shot failed to kill him immediately. The
    jury saw an animation depicting Englert’s opinion on how the
    shootings of Michael and Christopher occurred.            Englert
    7
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    testified that the inner thigh of Caro’s shorts showed a high
    velocity spatter — the kind associated with gunshots. Englert
    opined that the person wearing the shorts shot Christopher and
    he expressed confidence “beyond a reasonable degree of
    certainty.” Englert found transfer stains and no evidence of
    blood from a gunshot on Xavier’s jacket. Englert concluded that
    the person wearing the jacket was “not involved” in “a shooting.”
    He concluded gunshot spatter did not cause the blood stains on
    Xavier’s pants and sandals.
    Two officers interviewed Xavier on November 23, 1999, at
    5:30 a.m. at the family home. Xavier indicated Caro was taking
    Prozac, she had attention deficit disorder, had been drinking
    margaritas, and agreed with the officer that the alcohol and
    Prozac may have had a synergistic effect. At some point, he told
    officers he had prescribed the Prozac to Caro. Around 7:00 p.m.,
    officers escorted Xavier into his closet and let him obtain some
    items before he went to a hotel, but the officers did not catalogue
    items Xavier took from the house.
    The defense presented evidence that the white truck
    Xavier saw outside the gate while leaving the hospital had
    entered hospital grounds around 10:00 p.m., that Joey and
    Michael had died at 10:00 p.m. or later, and that it only took 30
    minutes to drive home at night — implying Xavier had enough
    time to kill the children and shoot his wife before the 11:21 p.m.
    call to 911. Defense expert Herbert MacDonnell reviewed the
    forensic evidence. He examined the shorts Caro was wearing
    under a microscope and did not find any high velocity impact
    spatter or mist. He did find projected blood on the inner crotch
    but opined that it was not the result of the shootings because of
    the confined spread of the stains and the small amount of blood.
    8
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    MacDonnell found transfer stains on Xavier’s jacket, socks, and
    pants.
    Dr. Frederick Lovell, a medical examiner, reviewed
    evidence concerning Caro’s head wound. He testified that the
    gun was held tightly against Caro’s head, at a right angle to the
    bone above Caro’s ear. The gun would have been pointed “[v]ery
    slightly downward.” When asked how Dr. Lovell would explain
    a bullet fragment found in the ceiling, he testified to previously
    saying that he did not know how it got there. He testified that
    it was “highly unlikely” that the gunshot wound was self-
    inflicted. It would have been difficult to hold the gun against
    the skull at the slightly downward angle. The bruises on Caro’s
    arms were consistent with finger grab marks. A criminalist
    found hair in Caro and Xavier’s master bedroom that looked like
    it had been pulled out, though some, maybe all, of the hair
    belonging to Caro came out by the force of the gunshot.
    The defense presented a number of character witnesses.
    They testified that Caro was an admirable, friendly, nice person
    who loved her children. Caro’s parents testified about their
    financial arrangements with Xavier and Caro. Juanita testified
    that, after the shootings, Xavier told her: “Wait til you hear the
    911 call, Juanita. You’re gonna blow your mind.” Later, Xavier
    told Juanita, step by step, how Caro killed the boys.
    Caro testified in her own defense. Caro was forthcoming
    with Xavier about expenditures while she served as office
    manager, and wrote checks to her parents for family trip
    expenses only after discussing them with Xavier. Caro was sad,
    but not angry, about being fired as office manager and losing
    control of the family finances in August 1999. Caro had no hard
    feelings toward her friend VanEssen, who replaced Caro as
    9
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    office manager. Caro never talked to VanEssen about killing
    herself. Xavier prescribed Prozac to Caro in August 1999 and
    increased her dosage in September or October 1999. Caro also
    took diet pills.
    Caro and Xavier were having marriage difficulties. In
    June 1999, Caro stayed at a hotel for three days to get away
    from the family. In August 1999, after Xavier fired Caro, he told
    Caro that they should separate. Later that month, Xavier told
    Caro that he was going to a divorce lawyer and discussed with
    Caro division of assets. Caro did not believe Xavier kept the
    appointment with the divorce lawyer, but later found notes from
    the meeting. Caro wanted to make the marriage work and was
    unaware of Xavier’s affair.
    Xavier had purchased Caro a firearm for home protection,
    as well as lessons for her to learn how to use the gun. Xavier
    never told Caro the combination to the gun safe and would get
    the gun out for her before he would go out of town. Caro would
    pop the safe open with the prong end of a hammer to put the gun
    back. Caro had not fired the gun since before Christopher was
    born and denied ever brandishing it at Xavier.
    Caro had only partial memories of the day on which the
    shootings occurred. She remembered the fight she had with
    Xavier. She remembered Xavier saying he was leaving, and she
    thought he meant he was leaving for good, though Caro did not
    remember Xavier actually leaving to go to the office. Caro could
    not remember what she wore that night. But she would not have
    been wearing the shorts she was found in because they were
    maternity shorts that were too big for her. She had never seen
    the T-shirt she was found wearing. Her last memory of that
    night was standing in the master bedroom closet, looking at a
    10
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    pitcher of margaritas. Caro had no memory of hurting her
    children. When she woke up she thought they had been in a car
    accident because she was injured, and Detective Wade said the
    boys were hurt. When she was told her boys were dead, she did
    not know how they died. Caro was sure she did not kill her
    children.
    On November 5, 2001, the jury found Caro guilty of three
    counts of first degree murder, found the firearm enhancements
    true, and found true the multiple-murder special circumstance.
    On November 6, 2001, Caro withdrew her plea of not guilty by
    reason of insanity.
    The penalty phase began on November 27, 2001. In
    aggravation, the prosecution presented evidence of prior acts
    that Caro allegedly committed. On June 30, 1992, Caro and
    another woman argued over a parking space. Caro ended up
    grabbing the other woman by the hair with both hands and
    pulling her head against the inside of the woman’s half-open
    driver-side window. In August 1988, during an argument, Caro
    punched Xavier in the face and fractured her knuckle. In 1996
    or 1997, Caro gave Xavier a black eye by hitting him, possibly
    with her hand or possibly by throwing a jewelry box. In the late
    1990s, Caro threw a necklace box at Xavier and hit him in the
    eye, causing a retinal tear that required laser eye surgery. Caro
    threw a “C” battery at Xavier during an argument in the late
    1990s that tore a hole in the screen door. During an argument
    sometime between 1997 and 1999, Caro threw a three-pound
    box of hot rollers at Xavier, which missed and broke the
    bathroom mirror. At another time in the late 1990s, Caro threw
    pizza, dishes, and silverware on the floor during an argument
    before approaching Xavier with a butter knife. Xavier stated
    that he did not hit Caro during these incidents. On cross-
    11
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    examination, the defense elicited from Xavier occasions when he
    was physically violent with Caro, including one time when he
    punched Caro, causing her to fall “like a sack of potatoes.”
    Xavier narrated a family video showing scenes of the three
    boys who had been killed. Xavier testified about the boys and
    their character traits.
    In mitigation, the defense presented evidence that Caro
    was a happy, obedient child. Her parents never used physical
    punishment. Caro played basketball and volleyball, was a
    cheerleader, and graduated from high school with a “C” average.
    Xavier was the second boyfriend Caro ever had. Caro’s first
    boyfriend testified that she was never violent with him or
    anyone else. Extended family members described Caro as a
    good, patient mother. Caro’s cousin, a pastor, and the Ventura
    County Jail chaplain, testified that Caro was a person of
    compassion, caring, and genuine Christian faith. Caro never
    admitted in her confidential sessions with the pastor and
    chaplain to killing her children. The children’s teachers
    testified that Caro spent hours volunteering in her children’s
    classrooms, and observed that she was a friendly, caring, and
    affectionate mother.
    Caro had a blood-alcohol level of 0.138 percent on the night
    of the shootings. According to a defense toxicology expert, Caro
    would have been staggering, would have felt sedated, and would
    have been impaired in her ability to process information. Her
    blood tested positive for Prozac and Xanax. Caro suffered from
    depression at the time of the shootings. A forensic psychiatrist
    attributed the killings and suicide attempt mostly to Caro’s
    depression. He believed Caro fell in the class of depressed and
    suicidal women who “primarily commit[] suicide” and kill their
    12
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    children as “a secondary act” to “prevent something bad from
    happening to the children they love.” A clinical neurologist
    testified that Caro suffered residual brain effects seven months
    after the shootings. He diagnosed Caro with chronic depression
    accompanied by mood congruent psychotic features, alcohol
    dependence, alcohol abuse, and a dependent personality. The
    neurologist believed Caro had amnesia resulting from her brain
    trauma and the combination of drugs she took. In the
    neurologist’s view, Caro was incapable of appreciating the
    nature and consequences of her actions on the night of the
    shootings.
    On December 10, 2001, following the penalty phase, the
    jury returned a verdict of death. On April 5, 2002, the trial court
    denied a motion for new trial and a motion to modify sentence.
    The trial court sentenced Caro to death on each count of murder,
    with concurrent sentences of 25 years to life for the firearm
    enhancements.
    II.    DISCUSSION
    A. Jury Screening Issues
    i.    Caro’s Presence for Stipulated Excusals of Jurors
    Caro contends she was entitled, as a matter of
    constitutional and statutory law, to be present when counsel for
    both sides discussed juror hardship in chambers and agreed by
    stipulation to excuse 62 potential jurors in an e-mail to the trial
    court. Jury screening in this case began on July 17, 2001. On
    that day, the trial court started introducing groups of
    prospective jurors to the facts of the case, soliciting applications
    for hardship excusals, and directing prospective jurors to fill out
    comprehensive juror questionnaires. The next day, the parties
    and the trial court discussed the prospect of stipulating to the
    13
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    excusal of some jurors for cause. On July 23, 2001, the
    prosecution stated it had begun “informal discussions with the
    defense” about jurors “who both sides think will be challenged,
    likely successfully, for cause.” Later that day, the trial court
    scheduled the parties to return on July 27, 2001, to address such
    stipulations. Defense counsel indicated she would exchange her
    list of potential “for cause” stipulations with the prosecution. On
    July 26, 2001, defense counsel sent an e-mail to the trial court
    identifying 62 prospective jurors both parties agreed the court
    could excuse “due to either hardship or cause.” Fourteen of the
    excusals included the notation “(hardship).” The e-mail did not
    indicate specific reasons for the remaining 48 prospective jurors.
    On July 27, 2001, the trial court stated that the e-mail
    stipulation had been filed and placed in the record. Caro was
    present at the proceedings before and after the e-mail
    stipulation. We assume Caro was absent from the informal
    discussions and agreement on stipulations.
    Caro argues she had the right to be present for these
    stipulation discussions and the stipulations. The federal
    Constitution provides a defendant the right to be present if “(1)
    the proceeding is critical to the outcome of the case, and (2) the
    defendant’s presence would contribute to the fairness of the
    proceeding.” (People v. Kelly (2007) 
    42 Cal.4th 763
    , 781-782.) A
    defendant’s right to be present under the California
    Constitution and section 977, subdivision (b)(1) is similar.

    must have a “reasonable, substantial relation to [a defendant’s]
    opportunity to defend the charges against him”]; People v.

    22 Cal.4th 690
    , 742.) The burden is on a
    defendant to show that the “ ‘absence prejudiced his case or
    denied him a fair and impartial trial.’ ” (Ervin, at p. 74; People
    14
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    v. Virgil (2011) 
    51 Cal.4th 1210
    , 1233-1234 (Virgil).) We reject
    general claims that a defendant might have provided useful
    input as “unduly speculative.” (Virgil, at p. 1234; see also People
    v. Benavides (2005) 
    35 Cal.4th 69
    , 89 (Benavides).)
    Caro fails to distinguish our prior decisions denying
    similar claims. In Ervin, the defendant challenged his absence
    from counsels’ jury “screening” discussions about stipulating to
    the excusal of “prospective jurors whose questionnaires showed
    they were probably subject to challenge and excusal.” (Ervin,
    supra, 22 Cal.4th at p. 72.) We found that the defendant’s
    presence at such discussions “would have served little purpose.”
    (Id. at p. 74.) The same is true here. Caro argues “she might
    have discouraged” the stipulated excusals. But even if such an
    argument could establish that Caro’s presence was necessary,
    such a contention does not establish prejudice: It is “unduly
    speculative” because nothing in the record indicates Caro would
    have actually discouraged the stipulations. (Virgil, supra, 51
    Cal.4th at p. 1234.)
    Caro asks us to reconsider our precedent in light of the
    Washington Supreme Court’s decision in State v. Irby (2011) 
    170 Wash.2d 874
     [
    246 P.3d 796
    ]. But in Irby, neither the parties nor
    their attorneys were present on the first day of jury screening,
    when the trial court administered juror questionnaires. (Id.,
    246 P.3d at pp. 798-799.) During that first day, the trial court
    e-mailed the parties and suggested that reason existed to excuse
    certain jurors — some for cause. (Ibid.) The e-mail indicated
    that the trial court wanted to confirm the excusals that same
    day, and the parties agreed by e-mail to dismiss some of the
    suggested jurors within the hour. (Ibid.) Irby is distinguishable
    from this case. The trial court here did not rush an out-of-court
    for-cause jury excusal proceeding within an hour, nor did it
    15
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    otherwise fail to provide a material opportunity for Caro to even
    see the prospective jurors. Irby thus gives us no occasion to
    reconsider our precedent in this case. We conclude the parties’
    stipulation to excuse jurors by e-mail did not violate Caro’s right
    to be present or cause her prejudice.
    ii.   Stipulation To Excuse Prospective Jurors
    Caro asserts the trial court erred by accepting the parties’
    stipulated excusals, identified in defense counsel’s July 26,
    2001, e-mail, without further inquiry. She argues that the trial
    court should have determined whether each juror was properly
    excusable for cause. She contends the trial court’s failure to
    make these determinations led to the improper excusal of
    qualified jurors and produced a biased jury.
    We find Caro’s challenge to the stipulation procedure
    forfeited and without merit. Although Caro attempts to
    characterize trial counsel’s e-mail and subsequent conduct
    otherwise, we find it clear in the record that counsel stipulated
    to these excusals. Counsel then expressed no objection to the
    court’s dismissing the listed prospective jurors based on the
    parties’ agreement. These actions forfeited her challenges on
    appeal. (E.g., People v. Duff (2014) 
    58 Cal.4th 527
     (Duff); People
    v. Booker (2011) 
    51 Cal.4th 141
    , 161 (Booker); see also People v.
    Visciotti (1992) 
    2 Cal.4th 1
    , 38; People v. Mitcham (1992) 
    1 Cal.4th 1027
    , 1061 (Mitcham).)
    Even if Caro’s argument were not subject to forfeiture, we
    find it unpersuasive on the merits. As we have held time and
    again, trial courts commit neither constitutional nor statutory
    error when they permit counsel to prescreen juror
    questionnaires and stipulate to juror dismissals. (See, e.g., Duff,
    supra, 58 Cal.4th at p. 540; Benavides, 
    supra,
     35 Cal.4th at pp.
    16
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    88-89; Ervin, 
    supra,
     22 Cal.4th at p. 73.) Stipulations benefit all
    parties “by screening out overzealous ‘pro-death’ as well as ‘pro-
    life’ venirepersons, and by substantially expediting the jury
    selection process.” (Ervin, at p. 73.) Here, as in other cases
    where we have found no error, “once the preliminary screening
    process had concluded, the court and counsel then conducted the
    usual voir dire examination of the remaining prospective jurors
    in selecting the actual jurors who would serve on defendant’s
    jury.” (Ibid.) Caro fails to establish error on these facts or
    persuade us to overrule our prior precedent.
    Finally, to the extent Caro complains that this procedure
    resulted in the improper excusal of jurors for cause, she is not
    entitled to relief. (See People v. Potts (2019) 
    6 Cal.5th 1012
    ,
    1052-1053 (Potts); Duff, supra, 58 Cal.4th at p. 540; Booker,
    
    supra,
     51 Cal.4th at p. 161; Mitcham, 
    supra,
     1 Cal.4th at p.
    1061.)
    iii. Dismissal of Two Prospective Jurors for Cause
    Caro argues the trial court improperly dismissed
    Prospective Jurors J.W. and D.S. for cause because of their
    views on the death penalty. Prospective jurors in a capital case
    who oppose the death penalty are not automatically disqualified
    “simply by virtue of their personal views on that punishment.”
    (People v. Fuiava (2012) 
    53 Cal.4th 622
    , 656.) A trial court
    should only dismiss a prospective juror for cause if the juror’s
    views would “prevent or substantially impair” that juror from
    carrying out their duty. (People v. Lancaster (2007) 
    41 Cal.4th 50
    , 78 (Lancaster).)
    a. Standard of Review
    On appeal, we review the trial court’s “for cause” juror
    excusals deferentially. If the juror’s voir dire responses conflict
    17
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    or are equivocal, we accept the trial court’s findings if supported
    by substantial evidence. (E.g., People v. Duenas (2012) 
    55 Cal.4th 1
    , 10 (Duenas).)
    Initially, Caro disputes this standard of review, asserting
    the trial court deserves no deference here because it
    misunderstood the applicable law. (Cf. People v. Cunningham
    (2015) 
    61 Cal.4th 609
    , 664 [de novo review appropriate where
    trial court applied incorrect standard in determining whether
    racial discrimination motivated prosecutor’s peremptory
    strike].) At times, the trial court described the inquiry as
    concerning whether a juror could be “neutral” as between life
    imprisonment without parole or death. We agree with Caro that
    on their own, such statements could misleadingly suggest a
    juror cannot serve if he tends to disfavor the death penalty.
    Instead, “[t]he critical issue is whether a life-leaning prospective
    juror — that is, one generally (but not invariably) favoring life
    in prison instead of the death penalty as an appropriate
    punishment — can set aside his or her personal views about
    capital punishment and follow the law as the trial judge
    instructs.” (People v. Thompson (2016) 
    1 Cal.5th 1043
    , 1065
    (Thompson).)
    Nonetheless, we find that in context, the trial court’s
    statements about neutrality were consistent with the proper
    inquiry: whether the prospective juror could “faithfully and
    impartially” follow the law (Thompson, supra, 1 Cal.5th at p.
    1066; accord, Lancaster, 
    supra,
     41 Cal.4th at p. 78), and
    “ ‘conscientiously consider all of the sentencing alternatives,
    including the death penalty where appropriate’ ” (Thompson, at
    p. 1064). In discussing whether J.W. could be “neutral,” the trial
    court expressed doubt that J.W. could “reasonably consider both
    punishments” as instructed by the court. The court, too,
    18
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    considered D.S.’s “ability to be neutral” to mean his ability to
    “give serious consideration to both potential punishments.”
    When the court explained the purpose of voir dire to prospective
    jurors on several occasions, it conveyed –– correctly –– that it
    could only accept “jurors who will not vote automatically for or
    against the death penalty.” The court also emphasized that
    jurors did not need “to choose between religious and ethical
    beliefs” and “the law,” as long as they nonetheless “obey[ed] and
    follow[ed] the law.” Moreover, we note the trial court did not
    excuse all jurors who had misgivings about the death penalty.
    In reviewing the sum of voir dire, we believe the trial court
    properly focused the inquiry on whether a juror could “weigh[]
    the aggravating and mitigating circumstances of the case and
    determin[e] whether death is the appropriate penalty under the
    law” (People v. Stewart (2004) 
    33 Cal.4th 425
    , 447), not just their
    personal views on the death penalty. Accordingly, we now turn
    to whether substantial evidence supported the excusals of J.W.
    and D.S.
    b. Prospective Juror J.W.
    Prospective Juror J.W. stated in his questionnaire that he
    “strongly support[s]” the death penalty where “clearly
    warranted.” He believed the death penalty was sought “[t]oo
    seldom.” J.W. indicated that the death penalty should not
    automatically apply for the murder of children because it
    “depends on circumstances,” though he “tend[s] to favor” the
    death penalty in such cases. Nonetheless, J.W. wrote that he
    “can’t help but have [a] gut reaction against [application of the
    death penalty to women] — unless clearly warranted.” J.W.
    wrote that his wife was “adamantly against” the death penalty.
    J.W. indicated that he would be able to listen to all the evidence
    and give honest consideration to both death and life, but also
    19
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    wrote that “a conviction with death penalty could damage my
    marriage. My wife has deep convictions.”
    During voir dire, J.W. stated that his views had changed
    since filling out the questionnaire. He stated that “it’s very
    unlikely I would vote for the death penalty in this case, but it’s
    not impossible” because of “[p]ersonal concerns and just
    convictions.” When defense counsel asked him to explain, J.W.
    stated, “I haven’t changed my convictions regarding the death
    penalty per se. Knowing what I know about this case and just
    being honest, I think it would be difficult for me to apply it.”
    J.W. stated that he did not have preconceived notions about the
    case, could conceive of a case where he would impose the death
    penalty, and stated he could be fair and impartial to both sides.
    But he indicated that his wife’s opposition to the death penalty
    “might” affect him. J.W. told his wife that he might sit as a juror
    on a capital case but did not give her any other details about the
    case. When asked if he could set aside his wife’s beliefs, J.W.
    stated, “I think so, but it’s — it’s a very difficult decision, and
    when there are personal ramifications, it’s hard to guarantee.”
    When pushed whether he could “forget about” his wife’s
    opinions, he said, “Yes.”
    The prosecutor asked J.W. whether he could go with
    imposing the death penalty and then go home to his wife. J.W.
    responded, “The reason I mentioned what I did is I know it
    would be okay in the short-term, and the long-term effects on
    our relationship would be, in my opinion, unpredictable.” J.W.
    said, “Yes,” when asked whether the effects on his relationship
    were something he would worry about while acting as a juror.
    When asked whether that was “something that perhaps would
    impair your ability to impose death in a case that called for it,”
    J.W. replied, “Perhaps.” When asked if he could personally
    20
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    impose the death penalty, J.W. said he easily could do so in a
    case like the Oklahoma City bombing, but followed up by saying,
    “I guess — I’m sorry. Also old-fashioned. The thought of
    imposing the death penalty on a woman is an effort.” When
    pushed on whether he could impose the death penalty on Caro
    after hearing about her background, he responded,
    “Theoretically, yes. I said it wasn’t impossible. I do think the
    probability is low.” He stated that he could impose death in a
    case involving a triple murder if he “heard enough factors that
    led me to think it was the right thing to do.” He stated that he
    would balance the aggravating and mitigating factors and could
    “[c]ertainly” impose death based on a single overwhelming
    aggravating factor, “depend[ing] on [his] judgment.”
    The prosecution challenged J.W. for cause, and the trial
    court excused J.W. because of his statements that he was
    unlikely to impose death and his feelings about imposing death
    on women. Based on J.W.’s responses, the trial court concluded
    J.W.’s “mind-set” would “substantially impair[] his ability” to
    “reasonably consider both punishments as a reasonable
    possibility in this case.” The trial court also relied on the fact
    that J.W. violated the court’s admonition not to talk about the
    case by telling his wife that he might sit as a juror in a capital
    case.
    Substantial evidence in the record supports J.W.’s excusal
    for cause. J.W. said he would worry about potential damage to
    his relationship with his wife when acting as a juror and said
    that it “[p]erhaps” would impair his ability to “impose death in
    a case that called for it.” We disagree with Caro that
    Wainwright v. Witt (1985) 
    469 U.S. 412
     requires the juror’s own
    views, not those of a third party such as his wife, to prevent or
    substantially impair his performance. This is an overly rigid
    21
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    reading of Witt. The inquiry is whether “the trial judge is left
    with the definite impression that a prospective juror would be
    unable to faithfully and impartially apply the law.” (Id. at p.
    426.) On this record, J.W.’s marital concerns justified such an
    impression.
    In addition, J.W. had a “gut reaction” against imposing the
    death penalty against a woman, a belief he stated in his
    questionnaire and repeated, unprompted, when asked whether
    he personally could impose death on a person. We acknowledge
    that J.W. gave statements indicating he would weigh the factors
    and impose death according to his judgment, but given the trial
    court’s superior position to evaluate the juror’s demeanor, tone
    of voice, and as the trial court put it here, his “mind-set,” we do
    not “interfere with the trial court’s resolution of” conflicting
    statements. (Lancaster, supra, 41 Cal.4th at p. 80; People v.
    Cain (1995) 
    10 Cal.4th 1
    , 60.) This is especially true because
    J.W. contrasted his ability to impose the death penalty in a case
    like the Oklahoma City bombing with this case — one involving
    a woman — where he only “[t]heoretically” could impose the
    death penalty.
    Given the substantial evidence supporting the trial court’s
    determination, we defer to its conclusion that J.W.’s statements
    amounted to substantial impairment.
    c. Prospective Juror D.S.
    Prospective Juror D.S. stated in his questionnaire that the
    death penalty “should be used only in the most extreme cases[.]
    I do not believe that killing the defendant is a solution for the
    first killing, so I would strongly object to the death penalty
    unless overwhelmingly convinced of intent free of mental
    impairments.” D.S. wrote that he supported life imprisonment
    22
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    without the possibility of parole “over the death penalty.” He
    indicated that he did not believe the death penalty serves any
    purpose. D.S. thought the death penalty was sought “[t]oo often”
    and “[r]andomly,” and that it is applied to “[t]oo many minorities
    and women, few white men.” When asked whether D.S.’s
    feelings about the death penalty were so strong that he would
    always vote against the death penalty, he placed a question
    mark in the “No” checkbox and wrote, “But almost always.” D.S.
    similarly indicated he “would require sufficient evidence to
    convince me that the death penal[ty] will serve a purpose beyond
    retribution.” When asked if he could listen to all the evidence
    and instructions and give honest consideration to both death
    and life imprisonment without parole, he placed a question
    mark in the “No” checkbox and wrote that he “would begin from
    the position that life without parole is enough punishment and
    no more is needed.” However, D.S. saw no reason why he could
    not be a fair and impartial juror.
    During the defense’s voir dire, D.S. stated, “If I
    understand the proceeding correctly, I would have no objection
    to deciding guilt or innocence. But when we got to the next
    phase, I would have some very definite thoughts on it.” When
    defense counsel asked whether D.S.’s thoughts would prevent
    him from keeping an open mind and considering all the
    evidence, D.S. replied, “I have some feelings that it seems to me
    might be in — in conflict with — I don’t know with what . . . .”
    After another question, he continued, “The problem is probably,
    it seems to me, that the — the problem is that I believe that a
    killing is a killing is a killing, and to kill a second time for
    vengeance because the first killing occurred is ridiculous unless
    there is proof offered that — that it would protect society, and
    then of course I think society comes first. [¶] So I — it’s a
    23
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    complicated thing, and I would — I don’t know exactly how to
    answer your question.” In response to a later question, he
    reiterated that he would not impose the death penalty unless
    there was a threat to society. Nonetheless, D.S. responded
    “[s]ure” when asked whether he would weigh the evidence and
    could impose death if the aggravating circumstances
    outweighed the mitigating circumstances. But he indicated that
    he was “not sure what those two terms mean” and that he
    “might not understand it.”
    During the prosecution’s voir dire, when asked whether
    D.S. could “ever impose death” in “this case,” D.S. responded, “I
    have yet to hear anything.” D.S. also noted there “[c]ertainly”
    existed a case where he would be able to impose death. D.S.
    indicated that his ability to vote for death in the case depended
    on the prosecution showing more than a “simple set of facts.”
    The prosecutor then asked D.S. whether life in prison would
    accomplish the goal of protecting society from a threat. D.S.
    replied, “Aren’t you saying that — in other words, you can’t
    prove that it — that it’s a threat to society, that the only thing
    you can prove is an actual murder and you want me to forecast
    what I would judge on what you may or may not prove? I can’t
    do that.” When pushed further on whether he could impose
    death on a person if life imprisonment without the possibility of
    parole would protect society, D.S. said, “Even — okay. That’s a
    tough one. There would be — it would be very difficult. . . . Very
    difficult. I don’t know exactly what the answer is. But I
    certainly will say it will be very difficult.” D.S. said he did not
    “have an answer,” whether there was any justification for the
    death penalty besides “protecting society.” He said he could
    impose death on another human. When asked if he could impose
    death on a defendant knowing the other option was life
    24
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    imprisonment without parole, D.S. said, “I can’t answer that
    kind of question. That’s too ethereal.” When pushed further on
    this topic, D.S. responded, “I cannot say that absolutely I would
    never do it” and that “[i]t’s possible. But I certainly have
    expressed hesitation.”
    The prosecutor challenged D.S. for cause. The trial court
    excused D.S. because of his hesitation to impose the death
    penalty and the limited society-protection rationale, which the
    court believed D.S. “unequivocally stated” would be “the only
    time” he would vote for death. Based on D.S.’s questionnaire
    and voir dire answers, the court “was left with the definite
    impression that the prospective juror would be unable to
    faithfully and impartially apply the law.” The trial court
    specifically noted D.S. “hesitated” when faced with the
    possibility that life imprisonment without the possibility of
    parole would satisfy D.S.’s society-protection rationale.
    After weighing the relevant information, the trial court
    determined that D.S.’s views substantially impaired his ability
    to set aside his personal beliefs and consider both sentencing
    options. Substantial evidence supports this conclusion. In his
    questionnaire, D.S. gave equivocal responses about his ability to
    vote for death. He believed he could be a fair and impartial
    juror, but also indicated that he would “almost always” impose
    life imprisonment without the possibility of parole. D.S. later
    wrote that it would be “very difficult” to impose the death
    penalty. These written answers certainly “are not magic
    phrases,” and would not alone support the conclusion that he
    was substantially impaired. (People v. Roldan (2005) 
    35 Cal.4th 646
    , 697 (Roldan); see also People v. Zaragoza (2016) 
    1 Cal.5th 21
    , 41 [where questionnaire responses do not “ ‘clearly reveal’ ”
    an inability to perform the juror’s duties, the trial court must
    25
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    examine the juror in court to ascertain the juror’s true state of
    mind]; see also People v. Buenrostro (2018) 
    6 Cal.5th 367
    , 415.)
    Here, however, substantial evidence supports the trial court’s
    conclusion that D.S.’s questionnaire, combined with his
    repeatedly equivocal voir dire responses on whether he could
    consider both punishments, reflected that impairment. (See,
    e.g., Duenas, supra, 55 Cal.4th at p. 12 [“Comments that a
    prospective juror would have a ‘hard time’ or find it ‘very
    difficult’ to vote for death reflect ‘a degree of equivocation’ that,
    considered ‘with the juror’s . . . demeanor, can justify a trial
    court’s conclusion . . . that the juror's views would “ ‘prevent or
    substantially impair the performance of his duties as a
    juror . . . ’ ” ’ ”]; Roldan, at p. 697.)
    Caro argues that D.S.’s responses show the picture of a
    thoughtful person who had not prejudged the evidence. But
    D.S.’s thoughtfulness could be reasonably understood to indicate
    unsureness whether his beliefs would allow him to ever impose
    the death penalty in a particular case. (Duenas, supra, 55
    Cal.4th at pp. 11-12 [“Many prospective jurors . . . ‘ “simply
    cannot be asked enough questions to reach the point where their
    bias has been made ‘unmistakably clear’ ” ’ ”].) As the trial court
    noted, that equivocation became especially pronounced when
    the prosecution pointed out that life imprisonment without the
    possibility of parole might eliminate any potential threat to
    society.3 (Cf. People v. Rountree (2013) 
    56 Cal.4th 823
    , 847
    3
    D.S.’s statement that he would only consider the death
    penalty if the defendant is a danger “to society” is ambiguous as
    to whether he meant society outside of prison or inside prison as
    well — though at one point he acknowledged that he may be
    talking about “danger to the public.” The jury can consider
    26
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    [upholding juror excusal where answers could “hardly have been
    more equivocal”]; cf. People v. McKinzie (2012) 
    54 Cal.4th 1302
    ,
    1342 (McKinzie) [upholding for cause excusal of jurors who
    would only impose the death penalty in narrow circumstances
    not at issue in the case].) In these circumstances, we defer to
    the trial court’s determination that D.S. would have been
    substantially impaired in carrying out his duties in the penalty
    phase.
    iv.   Prosecution’s Files on Prospective Jurors
    Caro contends that the trial court should have required
    the prosecution to turn over its investigatory materials on
    prospective jurors. The trial court agreed with the prosecution
    that such materials were undiscoverable work product. In
    People v. Murtishaw (1981) 
    29 Cal.3d 733
    , we gave trial courts
    “discretionary authority to permit defense access to jury records
    and reports of investigations available to the prosecution.” (Id.
    at p. 767.) In June 1990, California voters approved Proposition
    115, which added section 1054.6 to the Penal Code. It provides
    that “[n]either the defendant nor the prosecuting attorney is
    required to disclose any materials or information which are
    [privileged] work product . . . .” (§ 1054.6.) For purposes of
    section 1054.6’s discovery bar, work product includes a writing
    “that reflects an attorney’s impressions, conclusions, opinions,
    future dangerousness in prison (People v. Medina (1995) 
    11 Cal.4th 694
    , 766-767), but the prosecution cannot present expert
    testimony on that issue (People v. Avila (2006) 
    38 Cal.4th 491
    ,
    610). Regardless, D.S.’s responses at the very least show that
    he was not sure whether dangerousness in prison would ever
    allow him to impose the death penalty.

    or legal research or theories . . . .” (Code Civ. Proc., former
    § 2018, subd. (c), now § 2018.030, subd. (a); see Pen. Code,
    § 1054.6; People v. Zamudio (2008) 
    43 Cal.4th 327
    , 355 & fn. 14.)
    We need not decide whether the discovery request here solely
    sought work product or encompassed non-work-product
    material because any potential error was harmless. For any
    error of this type, it is “ ‘entirely speculative whether denial of
    access caused any significant harm to the defense.’ ”4 (People v.
    Pride (1992) 
    3 Cal.4th 195
    , 227; accord, Murtishaw, at p. 767.)
    We deny Caro’s claim on that basis.
    B. Issues at Trial
    i.    Clothing Seized from Emergency Room
    Caro argues the trial court erred by allowing the
    introduction of the clothing that Caro was found wearing the
    night of the shootings. In the alternative, Caro argues her trial
    counsel was constitutionally ineffective for not moving to
    suppress this evidence.      On the night of the shootings,
    emergency medical personnel brought Caro from her home to
    the    hospital    emergency      room     on    two   different
    4
    Nor has Caro persuaded us she is entitled to the limited
    remand procedure used to remedy error under Pitchess v.
    Superior Court (1974) 
    11 Cal.3d 531
    . In that context, a limited
    remand for the defendant to establish prejudice is appropriate
    because the reviewing court has already determined the
    defendant demonstrated “good cause” for the discovery
    requested below — including that the discovery is material to
    the litigation. (See People v. Gaines (2009) 
    46 Cal.4th 172
    , 179-
    181; City of Santa Cruz v. Municipal Court (1989) 
    49 Cal.3d 74
    ,
    85 [“The information sought must . . . be ‘requested with
    adequate specificity to preclude the possibility that defendant is
    engaging in a “fishing expedition.” ’ ”].) Caro made no such
    showing here.
    28
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    “backboards” — flat, firm boards used to safely transport
    injured patients. Deputy Jeffrey Miller arrived at the hospital
    after Caro. Miller found Caro’s shirt, pajama shorts, and
    underwear — which looked as if medical personnel had cut them
    off of Caro’s body — spread out on one of these backboards.
    Miller seized this clothing and gave it to a field evidence
    technician.
    Caro argues that the trial court should have excluded the
    clothing-related evidence because Miller did not have a warrant.
    Caro concedes, however, that defense counsel never brought a
    suppression motion related to this evidence or objected to its
    introduction on these grounds. This claim is thus forfeited. (See
    People v. Miranda (1987) 
    44 Cal.3d 57
    , 80.)
    In the alternative, Caro argues that her counsel at trial
    was ineffective for failing to bring a suppression motion. To
    establish ineffective assistance of counsel, Caro must show that
    her counsel’s performance was deficient and that she suffered
    prejudice from the deficient performance. (Strickland v.
    Washington (1984) 
    466 U.S. 668
    , 687-692.) On direct appeal, if
    the record “ ‘sheds no light on why counsel acted or failed to act
    in the manner challenged,’ ” we must reject the claim “ ‘unless
    counsel was asked for an explanation and failed to provide one,
    or unless there simply could be no satisfactory explanation.’ ”
    (People v. Wilson (1992) 
    3 Cal.4th 926
    , 936.) Where a defendant
    claims ineffective assistance based on counsel’s failure to
    litigate a Fourth Amendment claim, Strickland ’s performance
    prong requires her to show that it was objectively
    unreasonable — “that is, contrary to prevailing professional
    norms” — to forgo the motion. (Kimmelman v. Morrison (1986)
    
    477 U.S. 365
    , 385 (Kimmelman); see also People v. Lopez (2008)
    
    42 Cal.4th 960
    , 966 (Lopez) [the defendant bears the burden of
    29
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    showing counsel’s performance “ ‘ “fell below an objective
    standard of reasonableness [¶] . . . under prevailing professional
    norms” ’ ”].) Examining the Fourth Amendment claim’s merit
    has a role to play here. For example, “[c]ounsel is not ineffective
    for failing to make frivolous or futile motions.” (People v.
    Thompson (2010) 
    49 Cal.4th 79
    , 122.) The prejudice prong of
    Strickland then requires the defendant to “prove that [the]
    Fourth Amendment claim is meritorious and that there is a
    reasonable probability that the verdict would have been
    different absent the excludable evidence.” (Kimmelman, at p.
    375; accord, People v. Coddington (2000) 
    23 Cal.4th 529
    , 652
    (Coddington); People v. Wharton (1991) 
    53 Cal.3d 522
    , 576
    (Wharton).)
    Caro fails to establish that a motion to suppress the
    clothing would have been meritorious. Under the plain view
    doctrine, an officer may seize an item without a warrant if (1)
    the officer was lawfully in a place where the object could be
    viewed; (2) the officer had a lawful right of access to the seized
    item; and (3) the item’s evidentiary value was immediately
    apparent. (See Horton v. California (1990) 
    496 U.S. 128
    , 136-
    137; Payton v. New York (1980) 
    445 U.S. 573
    , 586-587;
    Arizona v. Hicks (1987) 
    480 U.S. 321
    , 327; People v. Bradford
    (1997) 
    15 Cal.4th 1229
    , 1295; see also U.S. v. Cellitti (7th Cir.
    2004) 
    387 F.3d 618
    , 623.) The doctrine does not amount to a full
    exception to the warrant requirement, but merely allows a
    warrantless seizure where an officer lawfully views, and can
    lawfully access, contraband or incriminating evidence.
    (Bradford, at p. 1295; Horton, at p. 137, fn. 7 [holding that even
    if incriminating evidence is in plain view in a suspect’s home, an
    officer cannot enter the home and seize the contraband without
    a warrant, absent exigent circumstances].)
    30
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    In this situation, the incriminating nature of the
    clothing –– covered in bloodstains after the shooting –– was
    immediately apparent. Caro raises the possibility that because
    she had shot herself in the head, the stains could have been her
    own blood. Yet that possibility does not eliminate the strong
    likelihood that some of the stains would link her or some as-yet-
    unidentified assailant to her or her sons’ injuries.
    Given the clothes’ evidentiary value, trial counsel would
    need to establish Officer Miller did not have lawful access to
    them in order to block their admission from trial. But the record
    is inconclusive on this point, as it fails to reveal where Miller
    was when he saw and seized the clothing from the board on
    which emergency personnel transported Caro. That ambiguity
    makes it quite difficult to assess the legality of Miller’s actions
    viewing and seizing Caro’s clothes. On this record, then, we
    cannot say the plain view doctrine was inapplicable, and Caro
    has not carried her burden to “establish that [her] Fourth
    Amendment claim ha[d] merit.” (Coddington, supra, 23 Cal.4th
    at p. 652.)
    ii.    Fifth Amendment Challenge to Caro’s Hospital
    Room Statements
    Caro argues that two statements she made to Detective
    Wade at the hospital should have been excluded from trial
    because (1) she did not receive the warnings required under
    Miranda v. Arizona (1966) 
    384 U.S. 436
     (Miranda) and (2) the
    statements were involuntary. The day after the shootings, Caro
    was moved to an intensive care unit (ICU) room after her
    surgery. In the afternoon, Wade arrived in plain clothes, and
    hospital personnel removed Caro’s breathing tube. Wade began
    sitting with Caro and stayed with her, or near her room, for two
    and a half to three hours before providing Caro Miranda
    31
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    warnings. Detective Rivera was also present in plain clothes.
    Wade recorded her conversation with Caro by placing a tape
    recorder on top of one of the machines near Caro’s bed, or at
    times, on the bed itself. Wade spent much of the interview
    getting Caro ice chips, adjusting pillows, helping Caro sit up or
    change positions, and relating information to nurses, such as the
    fact that Caro wanted medication or that she was in pain.
    Intermittently with this care, however, Wade asked Caro what
    happened. Caro was in pain during much of the discussion with
    Wade, but the level of pain seemed to decrease when the nurse
    gave Caro a codeine injection. Before the nurse gave the
    injection, she asked if Wade was “getting much” from Caro and
    checked in with Wade to make sure she would not “mess up
    [Wade’s] thing” by giving the injection. Wade responded that
    the nurse should do “what [the nurse] would normally do.”
    The two statements in dispute occurred at different times.
    At some point in the first hour and a half of questioning, before
    the codeine injection, Caro stated that she “might have fallen
    down the stairs,” but also indicated that she did not remember.
    About 45 minutes after the codeine injection, Detective Wade
    heard Caro say she was bruised by “wrestling with a boy.”
    After the second statement, Detective Wade continued to
    ask Caro questions about what happened, but Caro indicated
    that she did not remember, and asked whether her boys and
    Xavier were there. Wade told Caro that her boys were hurt and
    asked if she knew how they were hurt. Caro asked if it was
    “something serious.” Wade told Caro that she was investigating
    the death of Caro’s boys, and that Caro was suspected of hurting
    them. Wade then gave Caro Miranda warnings, and Caro
    invoked her right to counsel.
    32
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    In addition to Detectives Rivera and Wade, a psychologist
    hired by the district attorney, Susan Ashley, was present for
    much of the pre-Miranda-warning interview. After Caro said
    she might have fallen down the stairs, she noticed Dr. Ashley in
    the room, and asked who she was. Wade identified her as
    “Doctor Ashley” to Caro and may have mentioned she was a
    psychologist from the district attorney’s office. Caro also noticed
    a man from the district attorney’s office standing outside her
    door at one point, and Wade told her who he was. Caro asked
    why he was there and Wade told her he “was here because you
    got hurt. And we’re trying to figure out what happened.” After
    the first statement, but before the second, Caro asked a nurse
    why Wade was there, and the nurse responded, “I don’t
    know. . . . I’m not involved with that.”
    The evidence showed that Detective Wade failed to give
    Caro Miranda warnings before the two statements at issue.
    Nonetheless, it also showed that she did not threaten or make
    promises to Caro. The trial court also found that Wade did not
    interfere with Caro’s medical treatment and did not do
    “anything to overcome the will of” Caro. The trial court ruled
    that Caro was not in custody for purposes of Miranda during the
    Wade interview, and that Wade did not coerce an involuntary
    statement from Caro. Caro now challenges both rulings.
    Before they begin custodial interrogation of a suspect, the
    police have an obligation to deliver Miranda warnings. This
    familiar admonition warns the suspect of the right to remain
    silent, that any statement may be used as evidence against him
    or her, and that the suspect has a right to the presence of a
    retained or appointed attorney. (People v. Leonard (2007) 
    40 Cal.4th 1370
    , 1399-1400 (Leonard).) The warning is meant to
    protect the suspect’s privilege against self-incrimination, which
    33
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    is jeopardized by the inherently coercive nature of police
    custodial questioning. (Miranda, 
    supra,
     384 U.S. at pp. 478-
    479.)
    The purpose of Miranda guides the meaning of the word
    “custody,” which refers to circumstances “that are thought
    generally to present a serious danger of coercion.” (Howes v.
    Fields (2012) 
    565 U.S. 499
    , 508-509.) Such a danger of coercion
    is usually present where there has been a “ ‘ “formal arrest or
    restraint on freedom of movement” of the degree associated with
    a formal arrest.’ ” (People v. Stansbury (1995) 
    9 Cal.4th 824
    ,
    830, quoting California v. Beheler (1983) 
    463 U.S. 1121
    , 1125;
    see also People v. Moore (2011) 
    51 Cal.4th 386
    , 394-395.) The
    key question is whether, under all of the objective
    circumstances, a reasonable person in the suspect’s position
    would have felt free to terminate the interrogation. (Leonard,
    
    supra,
     40 Cal.4th at p. 1400; Howes, at p. 509; Thompson v.
    Keohane (1995) 
    516 U.S. 99
    , 112.) But even if a person’s freedom
    of movement has been curtailed, an “additional question” arises:
    “whether the relevant environment presents the same
    inherently coercive pressures as the type of station house
    questioning at issue in Miranda.” (Howes, at p. 509; see also id.
    at p. 510 [discussing Berkemer v. McCarty (1984) 
    468 U.S. 420
    ].)
    All objective circumstances of the interrogation are relevant to
    this inquiry, including the site of the interrogation, the length
    and form of questioning, and whether the officers have conveyed
    to the subject that their investigation has focused on him or her.
    (See Stansbury, at pp. 831-832.)            This initial custody
    determination does not depend on “the subjective views
    harbored by either the interrogating officers or the person being
    questioned.” (Stansbury v. California (1994) 
    511 U.S. 318
    , 323.)
    We have not explicitly discussed the custody analysis in a
    34
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    medical setting, but a handful of courts have addressed the
    issue. (See People v. Mosley (1999) 
    73 Cal.App.4th 1081
    , 1091;
    U.S. v. Martin (9th Cir. 1985) 
    781 F.2d 671
    , 672-673; U.S. v.
    Infante (1st Cir. 2012) 
    701 F.3d 386
    , 397-398; U.S. v. Robertson
    (10th Cir. 1994) 
    19 F.3d 1318
    , 1320-1321; U.S. v. Jamison (4th
    Cir. 2007) 
    509 F.3d 623
    , 629-633; U.S. v. New (8th Cir. 2007)
    
    491 F.3d 369
    , 374; Wilson v. Coon (8th Cir. 1987) 
    808 F.2d 688
    ,
    689-690; Reinert v. Larkins (3d Cir. 2004) 
    379 F.3d 76
    , 85-87.)
    Statements taken in violation of Miranda are
    inadmissible in the government’s case-in-chief. The prosecution
    may still use such statements for impeachment purposes. (E.g.,
    People v. Pokovich (2006) 
    39 Cal.4th 1240
    , 1247; People v. Peevy
    (1998) 
    17 Cal.4th 1184
    , 1193.) What the government may not
    use against a defendant for any purpose are any of her
    involuntary     statements.         We    consider     statements
    involuntary — and thus subject to exclusion under the Fifth and
    Fourteenth Amendments of the federal Constitution –– if they
    are the product of “coercive police conduct.” (People v. Williams
    (2010) 
    49 Cal.4th 405
    , 437.) We evaluate this question by
    looking to the totality of the circumstances to determine
    “whether the defendant’s ‘ “will has been overborne and his
    capacity for self-determination critically impaired” ’ by
    coercion.” (Id. at p. 436.) The presence of police coercion is a
    necessary, but not always sufficient, element. (Ibid.) We also
    consider other factors, such as the location of the interrogation,
    the interrogation’s continuity, as well as the defendant’s
    maturity, education, physical condition, and mental health.
    (Ibid.)
    When Detective Wade delayed giving Miranda warnings
    to Caro, she tread on perilous ground. True, Caro was not
    directly restrained by officers or informed she was under arrest.
    35
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    And she eventually received Miranda warnings — though only
    after two and a half hours of Wade’s off-and-on questioning.
    Hospital staff moved freely in and out of her hospital room.
    Wade’s urging one nurse to do “what [the nurse] would normally
    do” and the somewhat intermittent nature of Wade’s presence
    and questioning as hospital personnel tended to Caro or Caro
    rested may well have indicated to a reasonable person that she
    could be left to herself, if desired. And yet certain exchanges
    between Wade and the staff, and between Wade and Caro
    herself, may have suggested to a reasonable person that the
    police exercised some authority over whether she could
    terminate the interview. Specifically, we note the constant
    presence of one or more law enforcement officers and the
    suggestion of two staff members that they would not, or could
    not, interfere with the interview. Caro was also isolated from
    friends and family.
    Such circumstances heighten the risk of coercion. In
    Mincey v. Arizona (1978) 
    437 U.S. 385
    , the high court concluded
    a hospitalized suspect did not give voluntary statements after
    an officer engaged in “virtually continuous questioning” of a
    suspect who had requested to be left alone. (Id. at p. 401.)
    Because the officer persisted despite Mincey’s being “weakened
    by pain and shock” and “barely conscious,” and the “clear”
    indications “Mincey wanted not to answer” his questions (id. at
    p. 401), the court concluded Mincey’s “will was simply
    overborne” (id. at pp. 401-402).
    The record of the trial court’s decision indicates it made a
    contrary finding here — that Wade did not do “anything to
    overcome” Caro’s will or interfere with her medical treatment.
    Unlike the defendant in Mincey, Caro gave no clear indications
    prior to the challenged statements that she wished to end her
    36
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    interaction with Wade. But unquestionably, Caro’s situation
    here constrained her physical mobility: she was confined to her
    ICU bed with a broken foot and a drain in her head from brain
    surgery performed just hours before. She was fatigued and in
    significant pain. While a defendant’s “compromised physical
    and psychological condition” alone will not render her
    statements involuntary (People v. Panah (2005) 
    35 Cal.4th 395
    ,
    471), that condition is relevant to the inquiry and presents an
    opportunity for abuse.
    Whether the extent of Detective Wade’s engagement was
    sufficient to violate Caro’s constitutional rights is not a question
    we need to resolve. Even assuming the interview violated
    Miranda or the statements were involuntary, their admission
    was harmless beyond a reasonable doubt. The prosecution
    introduced the two statements to disprove the theory that
    Xavier inflicted the injuries. The prosecution also used these
    statements to argue that Caro remembered killing her children
    and was lying about her amnesia. But in retrospect, taking into
    account the full record of the proceedings, these statements did
    not have high value in the overall evidentiary calculus.
    For completeness, the jury heard testimony on Caro’s
    other statements to Detective Wade before and after indicating
    she could not remember what happened. This included Wade’s
    testimony that earlier in their conversation, she asked Caro
    whether she had “take[n] a fall or something,” and Caro asked
    Wade what had happened. In addition, both statements had
    plausible alternative explanations consistent with the defense’s
    theory and Caro’s purported lack of memory. Caro’s statement
    that she “might” have fallen down the stairs did not foreclose
    the possibility that Xavier caused her falling down the stairs —
    the prosecution’s theory that she fell down the stairs while
    37
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    “running through that house quite angry” was entirely
    speculative. And the defense presented testimony that, in an
    enhanced version of the tape, Caro was saying, “You have to ask
    the boys” rather than “wrestling with a boy.” There was also
    evidence in the record that Xavier had kicked Caro “on the legs”
    and in the “buttocks,” presenting a potential alternative
    explanation for Caro’s bruises. Given the potential to reconcile
    the challenged statements with Caro’s stating she could not
    remember what happened, we think it unlikely the jury put
    much weight on them as proving Caro remembered the killings.
    Had these statements been omitted, moreover, it would
    have been unlikely to affect consideration of the case’s
    compelling forensic evidence. Expert testimony about the
    bloody clothes Caro was found wearing provided a wealth of
    incriminating information. Five blood stains on her shorts
    matched Christopher’s DNA profile — Joey and Caro potentially
    contributed minor amounts of DNA to one of these stains each.
    One of these stains was yellow and appeared to be brain matter.
    Three other stains on Caro’s shorts matched Joey’s DNA. Some
    of the stains on the shorts appeared to come from projected
    blood. A prosecution witness testified that gunshot mist likely
    produced one of the stains that matched Christopher’s blood.
    While a defense expert testified that it was a stain more
    consistent with a beating, the defense expert acknowledged that
    the only evidence of violence against the children in the case
    involved gunshots. The shirt Caro was found wearing had 29
    blood stains — two matched Joey’s DNA, with Christopher and
    Michael as possible minor contributors, a control sample taken
    for one stain matched Christopher, and 19 stains matched
    Caro’s DNA profile.
    38
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Evidence gleaned from the house completed the
    evidentiary picture. Two bloody handprints matching Caro
    were on the door jamb in the bathroom between Joey’s room and
    Michael and Christopher’s room. Blood on the doorframe next
    to the hand prints tested positive for Joey’s blood, with minor
    contributions from Christopher. Blood on the sink in the
    bathroom matched Joey’s DNA, and one sample also had a
    potential minor contribution from Christopher.
    Further circumstantial support came from expert
    testimony regarding Caro’s own gunshot wound. Prosecution
    experts opined that the bullet damage found in the ceiling and
    in the wall above the bed was consistent with the gun being fired
    at an upward angle. The surgeon who operated on Caro testified
    that the bullet travelled upwards, and all of the bullet fragments
    were above the bullet hole in Caro’s head.
    In contrast, the evidentiary support for the defense’s
    alternative theory, which identified Xavier as the shooter, was
    comparatively weak. It ultimately did not sway the jury to
    doubt Caro’s guilt, and we are convinced excluding the
    challenged statements would not have made a difference. A
    defense expert opined that Caro did not shoot herself because
    the gun was held at an awkward, downward angle. But he did
    not have “the slightest idea” how a bullet fragment hit the
    ceiling. Prosecution and defense experts agreed that the blood
    stains on Xavier’s sweatpants, shirt, and jacket were almost
    certainly transfer stains. There was one projected bloodstain on
    Xavier’s sweatpants, matching Michael’s DNA. But as one
    expert testified, it was unlikely any of the stains came from the
    type of high-velocity spatter typically associated with shooting
    someone at close range. This would not have supported a
    conclusion that Xavier shot Michael. Instead, it was consistent
    39
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    with Xavier’s testimony that he had tried to give CPR to Michael
    and was carrying G.C., whose socks had become soaked in
    Michael’s blood. Moreover, tests found gunshot residue, but no
    blood, on swabs of Xavier’s hands — though Xavier testified he
    rinsed them at some point in the night. On the other hand, a
    swab of Caro’s right palm did show the presence of blood.
    Finally, the evidence showed that Xavier did not have
    much time between when he arrived home and called 911. A
    vehicle similar to Xavier’s Mercedes entered the parking area at
    9:24 p.m. and left at 10:36 p.m. The surveillance tape captured
    no    other     Mercedes     leaving     during     the     relevant
    timeframe — making defense counsel’s assertion that Xavier
    left earlier implausible. The evidence largely showed that it
    takes 40 to 46 minutes to drive from Xavier’s office to the family
    home — only one witness, Caro herself, testified to a shorter
    time (30 minutes). And the 911 call was at 11:21 p.m. Based on
    the prosecution’s evidence, Xavier would have only 5 minutes
    maximum between arriving home and calling 911. If the jury
    accepted Caro’s self-serving estimated driving time, he still
    would have no more than 15 minutes. A reasonable jury would
    not have believed Xavier shot his wife and children, hid all the
    blood evidence that might link him to the crime, and staged
    blood evidence corroborating his testimony within that window.
    Even if the jury accepted the possibility of this unlikely sequence
    of events, it stood at odds with the forensic evidence.
    In considering the picture that emerges from this
    evidence, we are persuaded beyond a reasonable doubt that the
    jury would not have reached a different result in this case had
    the court excluded the challenged statements.
    40
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    iii.   Ineffective Assistance of Counsel for Failure To
    File a Fourth Amendment Pretrial Suppression
    Motion
    Caro argues her counsel was constitutionally ineffective
    for failing to bring a pretrial suppression motion based on the
    Fourth Amendment to the federal Constitution. Caro asserts
    that such a motion could have challenged the introduction of
    (1) Caro’s bloody clothing; (2) the scrapings of Caro’s hands and
    feet after bags were placed over her appendages to preserve
    evidence; (3) photographs of Caro during surgery; (4) bullet
    fragments removed from Caro’s head; (5) statements Caro made
    in the surgery recovery room; and (6) statements Caro made in
    her ICU room.
    While she was unconscious, Caro was transported from
    the crime scene to the hospital. There, Caro’s clothes were cut
    off and left on the backboard used to transport her, where an
    officer recovered them. A surgeon removed bullet fragments
    from Caro’s head. Detective Rivera and forensic criminologist
    Debra Schambra were in scrubs and present during the surgery.
    Pictures taken by Rivera, Schambra, and other officers were
    admitted into evidence. After the surgery, a nurse gave the
    bullet fragments to Rivera, who later gave them to Schambra.
    Before the surgery, hospital staff placed bags over Caro’s hands
    and feet to preserve evidence, and in the recovery room,
    Schambra took fingernail scrapings and performed a gunshot
    residue test. Rivera testified to statements Caro made in the
    recovery room and her ICU room. Later, Detective Wade asked
    Caro a number of questions in her hospital room, and Dr.
    Ashley, a psychologist, listened to a portion of that questioning.
    We have already addressed Caro’s ineffective assistance of
    counsel claim arising from the failure to move to suppress Caro’s
    41
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    bloody clothing. In this part, however, we address a different
    set of issues implicated by Caro’s arguments. The Fourth
    Amendment limits searches and seizures where a defendant has
    a reasonable expectation of privacy in the place searched or item
    seized.    This encompasses the defendant’s property and
    possessory interests (see People v. Valdez (2004) 
    32 Cal.4th 73
    ,
    122), but also any privacy expectation “ ‘that society is prepared
    to recognize as reasonable’ ” (Carpenter v. United States (2018)
    ___ U.S. ___ [
    138 S.Ct. 2206
    , 2213]). So we must examine what
    reasonable expectation of privacy Caro had in her physical
    person and in other areas of the hospital, such as the operating
    room, the recovery room, and her ICU room.
    Caro’s primary contention is that Detective Wade violated
    the Fourth Amendment by entering her ICU room and then
    making observations and hearing Caro’s statements, both before
    and after the administration of Miranda warnings. (See People
    v. Cook (1985) 
    41 Cal.3d 373
    , 381 [“the police may not intrude
    into a hospital room” to see or hear the activities within “simply
    because hospital personnel routinely go in and out”].) Three
    statements were admitted from Wade’s conversation with Caro:
    Caro indicated that she may have broken her foot by falling
    down the stairs; that she might have gotten hurt by “wrestling
    with a boy”; and after receiving Miranda warnings and invoking
    her right to a lawyer, Caro spontaneously asked about where
    G.C. was located (and not about the other children).
    As we earlier concluded, the first two statements were
    harmless beyond a reasonable doubt. Any claim of ineffective
    assistance of counsel based on these statements necessarily fails
    for the same reason. (See, e.g., Wharton, 
    supra,
     53 Cal.3d at p.
    576 [defendant must show prejudice to prevail on a claim of
    ineffective assistance of counsel].) We also conclude that
    42
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    excluding the third statement, concerning G.C., would not
    produce a reasonable probability of a different result in light of
    the compelling forensic evidence and implausibility of the
    defense’s alternative theory. Counsel’s failure to have these
    statements excluded on Fourth Amendment grounds or
    otherwise did not prejudice Caro.
    Caro also asserts pictures taken of her in the operating
    room and in the recovery room violated her Fourth Amendment
    rights. At least one state has held that a defendant has no
    reasonable expectation of privacy in an operating room because
    of “a patient’s traditional surrender to his or her physician of the
    right to determine who may and may not be present during
    medical procedures.” (State v. Thompson (Ct.App. 1998) 
    222 Wis.2d 179
    , 192 [
    585 N.W.2d 905
    ].) But even though Caro may
    have had no dominion over the operating and recovery rooms,
    concerns about incursions on the privacy we maintain in our
    bodies are heightened during medical procedures. (See, e.g.,
    Sanders v. American Broadcasting Companies, Inc. (1999) 
    20 Cal.4th 907
    , 917 [citing cases where pictures of a patient in a
    hospital constituted an actionable intrusion upon seclusion
    under tort law]. But see Hernandez v. Hillsides, Inc. (2009) 
    47 Cal.4th 272
    , 294, fn. 9 [indicating that state tort law privacy
    rights are not necessarily coextensive with the 4th Amend.].)
    Nonetheless, we need not consider whether or in what
    circumstances the government’s taking of surgical images may
    invade a defendant’s privacy. Caro fails to adequately explain
    why the exclusion of these pictures would have, with a
    reasonable probability, altered the outcome of the case. Caro’s
    bloodstained clothes, with the high-velocity spatter and the
    potential piece of scalp, also established Caro’s presence around
    43
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    her children when they were shot, and, in the testimony of the
    prosecution expert, that she pulled the trigger.
    Caro similarly offers only cursory, unpersuasive
    arguments regarding any prejudice from the fingernail scraping
    and gunshot residue evidence police collected. To the extent
    those fingernail scrapings indeed showed the blood of Caro’s
    children, there was other evidence that Caro came in contact
    with her children’s blood.
    Caro also points to Detective Rivera’s presence in the
    recovery room and the ICU room. Rivera testified to Caro’s
    demeanor when he asked her questions, and when her surgeon
    asked her questions. But Caro fails to prove prejudice: her
    nurse and surgeon testified to Caro’s demeanor in these
    timeframes, so there is not a reasonable probability that the
    exclusion of Rivera’s testimony on these issues would have
    affected the outcome of the case.
    Finally, Caro argues that the recovery of bullet fragments
    from her head during surgery was an illegal seizure. The Fourth
    Amendment limits only governmental activity. (See, e.g.,
    United States v. Jacobsen (1984) 
    466 U.S. 109
    , 113.) Thus, the
    removal of a bullet by medical personnel acting independently
    of law enforcement directives does not implicate the rights
    therein. A hospital nurse handed the bullets from Caro’s head
    over to the police, and Caro fails to address whether the nurse
    was acting at the request of officers when doing so. (See
    Massachusetts v. Storella (1978) 
    6 Mass.App.Ct. 310
    , 315-316
    [
    345 N.E.2d 348
    ] [upholding finding that nurse was not a
    government agent in similar circumstances].) Nor does she
    explain why she retained a property interest or reasonable
    expectation of privacy in the fragments once removed. (See, e.g.,
    44
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Commonwealth v. Johnson (Pa. 1999) 
    727 A.2d 1089
    , 1098
    [holding the defendant had no reasonable expectation of privacy
    with respect to a bullet removed from him during surgery].) And
    even if officers improperly seized the fragments, Caro fails to
    meaningfully address any resulting prejudice.
    Caro argues that the evidence addressed here was
    cumulatively prejudicial. But for some she fails to show that the
    evidence should have been excluded, and she does not persuade
    us other allegedly excludable evidence was cumulatively
    prejudicial.   Caro’s Strickland claim must fail.           (See
    Kimmelman, 
    supra,
     477 U.S. at p. 375.)
    iv.    Denial of Request for Continuance
    Caro argues the trial court abused its discretion and
    violated due process by failing to continue a hearing on a motion
    to strike evidence that Caro asked about G.C. At trial, on
    September 17, 2001, Detective Wade testified that Caro asked
    about where G.C. was located, but not the three children who
    had been killed. On the next day of trial, September 18, 2001,
    Caro moved to strike Wade’s testimony about G.C., asserting the
    statement violated Miranda and her Fourth Amendment right
    to privacy. Caro’s Miranda argument asserted that Wade
    elicited the statement about G.C. by interrogation after Caro
    invoked her right to counsel. The Fourth Amendment argument
    asserted that Wade’s presence in the hospital room violated
    Caro’s reasonable expectation of privacy.
    The hearing on the motion spanned over three days. The
    hearing began on the afternoon of the next day, September 19,
    2001. The prosecution called Detective Wade to testify. The
    defense’s cross-examination of Wade went long, so the trial court
    continued the hearing to the following morning. The following
    45
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    day, September 20, 2001, the defense cross-examined Wade for
    a short amount of time in the morning and in the afternoon.
    During the afternoon cross-examination, the trial court asked
    defense counsel for a time estimate on any further evidence in
    the hearing. Defense counsel indicated that she needed 20
    additional minutes to cross-examine Wade, and 10 to 15 minutes
    to present the testimony of Nina Priebe, a social worker who
    worked at the hospital. Because of Ms. Priebe’s limited
    availability, defense counsel requested — and the trial court
    allowed — the hearing to continue to the following morning
    rather than later that day. The trial court did so with some
    trepidation, given the potential unavailability of prosecution
    witnesses the following week.
    The next morning, on September 21, 2001, Priebe testified
    that she was a social worker at the hospital, and worked in the
    ICU on the day Detective Wade questioned Caro. Priebe heard
    screaming from Caro’s room (likely right after Wade told Caro
    that her children had died), but did not go in because a nurse,
    Debbie Anderson, had told her that “police had asked us not to
    comfort” Caro. The prosecution objected on hearsay grounds,
    and the trial court sustained the objection.
    After Priebe’s testimony, defense counsel stated that she
    wanted to call Nurse Anderson as a witness, but indicated that
    she had been unable to contact her, and wanted to consult with
    an investigator. Anderson had testified in the case previously
    as a prosecution witness. But defense counsel stated she had
    been unable to contact Anderson because the only contact
    information defense counsel had was Anderson’s work phone
    number, and Anderson had not been to work the prior two days.
    The court denied the request because “[a]ll parties knew today
    was the day we were going to have the hearing”; defense counsel
    46
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    “had ample opportunity to have [her] witnesses present[;] . . .
    [a]nd the Court ha[d] been I believe extremely generous in
    allowing time for this hearing and for other hearings that have
    been occurring at the — the last minute.” Caro now argues the
    denial of a continuance was an abuse of the trial court’s
    discretion and a violation of due process.
    The decision to continue a hearing so a party can secure
    the presence of a witness is one within the trial court’s
    discretion. (People v. Roybal (1998) 
    19 Cal.4th 481
    , 504.) A trial
    court does not abuse its discretion in denying a continuance
    unless the defendant establishes good cause for a continuance.
    (Ibid.) Good cause requires a defendant to show that he or she
    exercised due diligence in pursuing the witness’s presence, the
    witness’s expected testimony was material and not cumulative,
    the testimony could be obtained within a reasonable time, and
    the facts the witness would provide could not otherwise be
    proven. (Ibid.)
    We conclude the trial court did not abuse its discretion. As
    the trial court observed, counsel for both parties knew that the
    final part of the hearing would occur on September 21, 2001, a
    schedule somewhat determined by prosecution witness
    availability. Defense counsel did not raise the possibility of
    calling Anderson until the last minute. And Priebe’s testimony
    that Anderson said that police told Anderson hospital staff
    should not comfort Caro was clearly hearsay if offered for the
    truth of the fact that police made that statement to Anderson.
    So counsel could have predicted the need for Anderson’s
    testimony. Defense counsel asserted that she had no way of
    contacting Anderson because she had not been at work for two
    days, but defense counsel failed to explain what steps she had
    taken to contact Anderson, when those efforts were made, and
    47
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    whether Anderson could be found in a reasonable time. Defense
    counsel also failed to argue that Anderson was the sole witness
    who could establish a police policy against comforting Caro that
    night. So the trial court did not abuse its discretion by denying
    a continuance.
    Moreover, the trial court denied the motion to strike
    because (1) the statement at issue was “spontaneous” rather
    than the result of an interrogation under Miranda, and (2) the
    court had no jurisdiction to hear the Fourth Amendment issue.
    Anderson’s testimony that police told hospital staff not to
    “comfort” Caro would have been irrelevant to the resolution of
    these issues. The trial court also concluded the statement was
    spontaneous and “voluntarily [made] by” Caro. Caro contends
    that Anderson’s proposed testimony that hospital staff were
    asked to refrain from comforting Caro is relevant to whether
    Caro’s spontaneous statement uttered after the Miranda
    warning was involuntary. Although such proposed testimony
    may be relevant in principle, it does not support Caro’s
    contention in this case because Caro’s statement was still a
    spontaneous utterance, not the product of police coercion. (See
    Colorado v. Connelly (1986) 
    479 U.S. 157
    , 167.)
    Nothing in the record shows that officers sought to limit
    Caro’s medical care or access to an attorney, and at the time the
    statement was made, Detective Wade was actively trying to find
    Caro’s mother so that she could come comfort Caro. Caro’s
    further contention that the testimony may have justified
    reconsideration of the trial court’s prior Miranda and
    voluntariness findings is purely speculative. If Anderson’s
    testimony would have warranted such an action, counsel might
    have obtained a declaration from Anderson and moved for
    reconsideration of the court’s prior Miranda ruling, but did not
    48
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    do so. So the trial court did not abuse its discretion or violate
    any constitutional rights by failing to grant the continuance.
    v.      Exclusion of Evidence Assertedly Implicating
    Right to Present a Defense
    a. Records from Xavier’s Therapist
    Caro argues that the trial court erred by refusing to review
    and order the disclosure of records from Xavier’s visits to a
    therapist. Before trial, Caro subpoenaed records maintained by
    Xavier’s therapist. The therapist moved to quash the subpoena,
    relying on the psychotherapist-patient privilege and the right to
    privacy. The therapist also argued that Caro did not have the
    right to pretrial in camera review of the records under People v.
    Hammon (1997) 
    15 Cal.4th 1117
     (Hammon). Xavier supported
    the therapist’s motion. Caro opposed the motion. After a
    hearing, the trial court found that the psychotherapist-patient
    privilege applied and that our decision in Hammon prevented
    pretrial disclosure of privileged information. The trial court also
    found that Caro failed to establish “good cause” because she had
    not shown a “reasonable likelihood that the documents in
    question contain information that is both material and favorable
    to the defense and that the same or comparable information is
    not obtainable from nonpriv[i]leged sources.”
    Before us, Caro argues she has a federal and California
    constitutional right to an in camera hearing to examine Xavier’s
    psychotherapy records, based on her right to confront and cross-
    examine witnesses.       Caro contends that our decision in
    Hammon, which rejected such an argument, was wrongly
    decided. In Hammon, we declined to provide a pretrial right to
    discovery under the confrontation clause, and instead found that
    any such right under the confrontation clause attaches at trial.
    49
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    (Hammon, 
    supra,
     15 Cal.4th at pp. 1127-11288.) Although the
    advent of digitized, voluminous records may conceivably raise
    new and challenging issues in this context, we decline to
    reconsider Hammon on these facts, which involve
    psychotherapy records from the relatively short period of time
    from August 4, 1999, to November 22, 1999. Moreover, Caro
    does not argue that the lack of pretrial discovery prejudiced her
    ability to request psychotherapy records at trial, or somehow
    altered her trial strategy. Nor does Caro argue on appeal that
    any requests for psychotherapy records were improperly denied
    at trial. In addition, Caro’s primary contention on appeal that
    the records might have shown that Xavier fired Caro to
    consummate his affair rather than to fix the office’s finances is
    speculative at best. We cannot conclude that the trial court’s
    ruling interfered with Caro’s right to confrontation in this case.
    b. Admission of Child Autopsy Photos
    Caro argues that four admitted autopsy photos showing
    the victims’ wounds were so gruesome and inflammatory that
    their admission was unduly prejudicial under Evidence Code
    section 352. The trial court has broad discretion over the
    admission of photographs that are alleged to include disturbing
    details. (Roldan, supra, 35 Cal.4th at p. 713; see also People v.
    Bonilla (2007) 
    41 Cal.4th 313
    , 353-354.) We routinely uphold
    the admission of autopsy photos to establish the placement of a
    victim’s wounds and clarify the testimony of prosecution
    witnesses. (See, e.g., McKinzie, supra, 54 Cal.4th at pp. 1351-
    1352.) The prosecution is not limited to proving its case “solely
    from live witnesses; the jury is entitled to see details of the
    victims’ bodies to determine if the evidence supports the
    prosecution’s theory of the case.” (People v. Gurule (2002) 
    28 Cal.4th 557
    , 624.)
    50
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    The prosecution sought to introduce 14 autopsy photos.
    The trial court excluded four of these photos as unduly
    prejudicial and cumulative. It allowed the introduction of the
    remaining 10 photographs. Caro now challenges four of the 10
    admitted photographs. People’s exhibit 40A was a close-up
    picture of the gunshot wound to Joey’s head, showing some
    tearing around the wound, which a prosecution witness used to
    opine that the gun was touching Joey’s head when fired.
    Similarly, People’s exhibit 42B was a close-up picture of the
    wound to Michael’s head, which similarly was used by an expert
    to opine that Michael suffered a contact gunshot wound because
    of visible hemorrhaging and tearing around the wound. People’s
    exhibit 44B showed a large, gaping torn injury in Christopher’s
    head, which demonstrated the damage caused by two gunshot
    wounds. People’s exhibit 44C was a closer view of the wound
    Christopher suffered, which a prosecution witness used to
    explain how the bullet entered and exited Christopher’s skull.
    Each of these photos served an evidentiary purpose by
    supporting the expert’s explanation of how the shootings
    occurred. Although the cause of death was not disputed at trial,
    these photos provided valuable context for understanding how
    the expert reached her conclusions about the nature of the
    shootings.    (See Booker, 
    supra,
     51 Cal.4th at p. 170
    [“photographs of murder victims are relevant to help prove how
    the charged crime occurred”].) Photographic evidence that Joey
    and Michael were killed by contact gunshot wounds and that
    Christopher was shot twice tended to demonstrate
    premeditation, deliberation, and the intent to kill. Moreover, we
    cannot conclude that these photos were unduly prejudicial.
    Although these photos constituted graphic images of gunshot
    wounds, even showing the insides of the victims’ heads in the
    51
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    case of exhibits 42B and 44B, we do not believe they were “ ‘so
    gruesome as to have impermissibly swayed the jury.’ ” (People
    v. Burney (2009) 
    47 Cal.4th 203
    , 243, italics added.) The
    pictures were limited to the result of the gunshot wounds
    themselves. They included no gratuitous details, unlike the
    pictures at issue in cases where courts have found an abuse of
    discretion. (See, e.g., People v. Marsh (1985) 
    175 Cal.App.3d 987
    , 996 [finding prejudicial photos of a child’s dangling bloody
    scalp with, in the background, the child’s blood-spattered torso
    “with the ribcages rolled back to expose the bowels”].) On
    balance, we conclude that the trial court did not abuse its
    considerable discretion in finding that the prejudice arising from
    the photographs did not substantially outweigh their probative
    value.
    c. Rulings on the Parties’ Objections
    Caro argues that the trial court erred in sustaining
    multiple prosecution objections and overruling multiple defense
    objections at trial. We review evidentiary rulings, including
    ultimate rulings on whether evidence should be excluded as
    hearsay, for abuse of discretion. (People v. DeHoyos (2013) 
    57 Cal.4th 79
    , 131, 132.) When a hearsay exception requires
    foundational findings of fact, we review such findings for
    substantial evidence. (Id. at p. 132.)
    First, Caro contends that the trial court erred by allowing
    Xavier to testify that Caro gave more money to her parents than
    was documented by the checks in evidence. A lay witness must
    have personal knowledge of the facts to which he or she testifies.
    (Evid. Code, § 702.) Xavier testified “those checks represent only
    a fraction of what was paid to [Caro’s parents] over that period
    of time for their expenses.” Caro contends the prosecution laid
    52
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    insufficient foundation of Xavier’s personal knowledge of how
    much Caro paid to her parents. But the prosecution established
    earlier that Xavier reviewed his corporate and personal finances
    in August 1999, which established a foundation for Xavier’s
    personal knowledge. Thus, the trial court did not abuse its
    discretion.
    Second, Caro argues that the trial court erred by not
    allowing defense counsel to cross-examine Xavier about the
    location where he had sex with Laura G., the woman with whom
    he was having an affair, after the shootings. After the trial
    began, Xavier told the prosecution that he had sex with Laura
    at the Marriott Hotel where Xavier stayed for two or three
    months. Laura told the police that she and Xavier had not had
    sex at the Marriott Hotel, but had continued their affair. At
    trial, Xavier denied having sex with Laura at a hotel — a
    statement inconsistent with his prior statement. The trial court
    excluded this evidence because it considered the continued
    affair — but not its precise location — relevant to the case. The
    trial court alternatively excluded the evidence because its
    probative value was substantially outweighed by “its undue
    influence, bias, and consumption of time” under Evidence Code
    section 352. The trial court has broad discretion to exclude
    impeachment evidence where the subject matter is “collateral”
    with “no logical bearing on any material, disputed issue.”
    (People v. Contreras (2013) 
    58 Cal.4th 123
    , 152.) The location of
    a witness’s affair may be relevant in some cases. But here, Caro
    sought to establish a potential motive for Xavier to kill his
    children by showing the continued affair. Caro did not argue
    below, and fails to argue on appeal, how the location would be
    relevant to anything except Xavier’s inconsistency and
    credibility on that issue. Moreover, given its collateral nature,
    53
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    the trial court did not abuse its discretion by alternatively
    excluding the evidence under section 352. This is especially true
    because other evidence was elicited from Xavier showing the
    relationship continued soon after the shootings: He testified
    that he kissed Laura and was still in love with her in December
    1999 or January 2000. The precise location of the affair’s
    continued consummation was a minor collateral issue. The trial
    court did not abuse its discretion.
    Third, Caro argues that the trial court erred by allowing
    prosecution expert Edwin Jones to testify that the prosecution
    made Caro’s underwear available to the defense.                    In
    Coddington, 
    supra,
     23 Cal.4th at page 606, we held the work
    product privilege is violated where the prosecution asks
    questions that “invit[e] the jury to infer that . . . other [defense]
    experts were not called because their testimony would not be
    favorable.” Here, Jones was a prosecution forensic scientist who
    testified on defense cross-examination that he examined Caro’s
    underwear on July 10, 2001. Defense counsel asked if that was
    the first time Jones had examined the underwear, and he
    replied that he examined it “on a date earlier than that when
    other examiners were looking at [it],” those other examiners
    being “Richard Fox or Herb MacDonnell. One of those two or
    both.” On redirect, the prosecution asked, “[W]ho is Richard
    Fox?” and defense counsel objected to the question under
    Coddington. Though, defense counsel said she would not object
    to testimony that the prosecution made the underwear available
    to the defense. The trial court sustained the objection. The
    prosecution then asked Jones if he “provide[d] access to that
    particular item to defense experts?” He replied, “Yes,” and
    defense counsel did not object. Defense counsel waived a claim
    challenging this question by saying she would not object to
    54
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    testimony that the prosecution made the underwear available to
    the defense. To the extent the question that was asked exceeded
    the scope of the waiver, Caro forfeited any claim by failing to
    object. (People v. Seumanu (2015) 
    61 Cal.4th 1293
    , 1365.)
    Moreover, the testimony was admissible. (See People v. Scott
    (2011) 
    52 Cal.4th 452
    , 489.) The trial court did not abuse its
    discretion.
    Fourth, Caro contends the trial court abused its discretion
    by not allowing a police officer to testify that Xavier told him
    that a psychotherapist advised Xavier to increase Caro’s Prozac
    dosage. Defense counsel proffered this testimony to impeach
    Xavier’s testimony on what he told police about Caro’s Prozac
    and to show that Xavier was trying to convince the police that a
    professional agreed with the increased Prozac prescription.
    Earlier in the trial, defense counsel had asked Xavier, “Did you
    tell the police when you were interviewed initially that your
    psychologist had prescribed Prozac for Cora?”5            Xavier
    responded, “I don’t recall if I used those words when I spoke to
    the sheriff’s department.” When asked if he had discussed
    Prozac with the police, Xavier stated, “To the best of my
    recollection, I mentioned to [the police] that Cora had been
    started on Prozac by me.” Xavier denied that he tried to
    intentionally mislead the police about who prescribed the Prozac
    to Caro.
    The trial court held that the police officer could not testify
    to Xavier’s statement to police that a psychotherapist had
    advised Xavier on prescribing Prozac to Caro. According to the
    trial court, this was not an inconsistent statement that fell
    5
    Trial witnesses at times referred to Caro by her nickname,
    “Cora.”
    55
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    within a hearsay exception. To the extent this testimony was
    proposed for purposes of showing Xavier’s attempt to seem more
    credible to police, the trial court held that, on the record before
    the court, Caro had not established a statement that implied
    such an attempt. Indeed, defense counsel indicated that they
    had not yet “gotten to” that part of the transcript of the police
    interview.
    We conclude any error was harmless. If the evidence was
    admitted for its truth, it would not have harmed — and may
    have bolstered — Xavier’s credibility, as evidence that he
    received advice about Caro’s Prozac. Moreover, the purported
    inconsistency in the statement would have been unlikely to alter
    the jury’s evaluation of Xavier’s credibility because defense
    counsel’s question about what Xavier told police was general,
    and he added the caveat that he was responding to the “best of
    [his] recollection.” This evidence also would not have provided
    much support to the defense theory that Xavier sought to
    manipulate the police. Xavier simultaneously told police that
    he was the one who actually prescribed the Prozac; the advice of
    a family therapist not allowed to prescribe Prozac herself would
    not have added much legitimacy to his decision. Therefore,
    there is no reasonable probability this evidence would have
    changed the trial’s outcome.
    Fifth, Caro argues that the trial court erred by excluding
    the defense’s proposed question to Caro, during direct
    examination, about whether Xavier told her he had kept his
    appointment with a divorce lawyer. On defense objection, the
    trial court held that the question called for hearsay and the
    answer would not be relevant to Caro’s proposed inconsistent
    statement hearsay exception theory. Some questions later, Caro
    testified to believing Xavier had not kept the appointment with
    56
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    the divorce lawyer based on Xavier’s statements to her. Caro
    argues on appeal that this was the nonhearsay purpose for
    which the excluded testimony should have been admitted. But
    since this fact was established by the later testimony, no
    possible prejudice arose from the prior ruling.
    Sixth, Caro argues that the trial court erred by allowing
    Detective Wade to testify to what Juanita said about Caro’s
    statements. In the hospital, Juanita asked Caro, “Why did you
    do this?” and then said a prayer over Caro. During the prayer,
    Caro said “My babies. My babies. I’m sorry. I’m sorry.” The
    prosecution sought to introduce evidence of Juanita’s later
    statement to Wade that recounted Caro saying that she was
    “sorry for what happened to my babies.” Defense counsel
    objected that the testimony constituted Juanita’s speculation
    about why Caro was sorry. The trial court disagreed and found
    that Juanita was not speculating, but rather was attributing the
    statement to Caro. In context, the trial court reasonably
    interpreted Juanita’s statement as reporting what she thought
    Caro had said in response to her question asking why Caro did
    it. To the extent another interpretation was possible, we cannot
    conclude that the trial court abused its discretion by resolving
    this factual dispute in a reasonable manner. (See People v.
    Thornton (2007) 
    41 Cal.4th 391
    , 429 [“The court’s ruling did not
    fall outside the bounds of reason”].)
    Seventh, Caro argues that the trial court should have
    allowed her to introduce transcript excerpts containing
    statements Xavier made to Juanita after the shootings. In a
    conversation recorded by Deputy Anthony Tutino, Xavier told
    Juanita the following: “[Caro] shot them in the head. She
    wasn’t messing around.” Defense counsel argued that this
    statement was relevant inconsistent statement evidence
    57
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    because Xavier had never specifically testified about observing
    where Joey was shot in his direct testimony. Defense counsel
    also contended that this statement showed that Xavier had
    greater knowledge about how the children died than he should
    have had based on his direct testimony. The trial court
    ultimately denied the motion as to these transcript excerpts.
    Even if the trial court erred by excluding this evidence, any such
    error was harmless. Deputy Tutino had earlier testified to this
    same statement during the prosecution’s case, and defense
    counsel ultimately referenced it during jury argument.
    Admitting a transcript of Xavier’s exact words in addition to
    Tutino’s testimony would have been largely cumulative and
    unlikely to affect the outcome of the case.
    d. Exclusion of Written Statement in Police Report
    Caro argues the trial court erred by excluding a statement
    in a police report. Deputy Tutino wrote — in a paragraph
    concerning statements Xavier made to Juanita in the garage the
    day after the shootings — that “[Caro] told Xavier that she had
    killed all the kids.” The prosecution argued that admitting this
    statement would violate the rule against hearsay because it was
    an out-of-court statement to be admitted for the truth of the
    matter asserted. This statement implicates three potential
    hearsay statements: the first level is Caro’s supposed statement
    to Xavier that she killed the children; the second is Xavier’s
    assertion that Caro made the statement; and the third is
    Tutino’s writing about what Xavier said.
    Caro contends that the purpose for admitting the
    statements only implicated the third level of hearsay — the
    police report itself. Caro argues that the first two levels of
    hearsay could be avoided because the statement would not have
    58
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    been admitted for the truth of Caro committing the murders, or
    for the truth of Caro telling Xavier she committed the murders.
    Instead, Caro argues that Xavier’s statement would have shown
    Xavier’s attempt to place blame on Caro and impeach his
    credibility. Regarding the police report, Caro argues that it fell
    within Evidence Code section 1237, which provides a hearsay
    exception for past recollections recorded. The trial court found
    that this exception did not apply.
    The Attorney General does not defend the trial court’s
    exclusion of the statement, but rather argues that any error was
    harmless. We agree any error was harmless for the limited
    purposes for which the statement would have been admitted.
    The statement’s purpose was to impeach Xavier’s testimony
    about what he said in the garage and to show that he was trying
    to lay blame on Caro. This statement that Tutino wrote down,
    but did not remember, and which was not on the tape recording
    of the conversation in the garage, had low evidentiary value.
    Juanita also never testified that Xavier made such a statement
    to her, and Xavier did not remember making the statement. The
    jury would be unlikely to find Xavier measurably less credible
    had this statement been admitted. Moreover, the theory that
    this statement showed Xavier’s attempt to lay blame on Caro
    does not hold up under scrutiny. It is unclear why Xavier would
    tell Juanita — but not the police — that Caro admitted to the
    crime if he shot his family and was trying to blame Caro. So for
    the limited purposes for which the statement would have been
    admitted, we conclude that any error was harmless.
    e. Cumulative Error and Right To Present a
    Defense
    Caro argues the trial court’s evidentiary errors are
    prejudicial when considered cumulatively, and also violated her
    59
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    constitutional right to present a defense. To the extent we
    assumed error, but found harmlessness with respect to Caro’s
    evidentiary arguments, we do not find that those errors are
    cumulatively prejudicial.       Those assumed errors involved
    evidence that was so minor that it was unlikely to have affected
    the case, even in the cumulative, and did not affect Caro’s right
    to present a defense. (See People v. Samuels (2005) 
    36 Cal.4th 96
    , 114 [“ ‘generally, violations of state evidentiary rules do not
    rise to the level of federal constitutional error’ ”].)
    vi.    Admission of Computer Animation
    Caro argues that the trial court abused its discretion by
    allowing the prosecution to show the jury a computer animation
    depicting the opinion of Rod Englert, a blood spatter expert, on
    how the shootings of Christopher and Michael occurred. We
    review a trial court’s decision to admit demonstrative evidence
    for abuse of discretion. (Duenas, supra, 55 Cal.4th at p. 21.)
    Before trial, the prosecution moved to introduce the computer
    animation, and the defense opposed. The prosecution argued
    the animation was admissible as a visual depiction of Englert’s
    expert opinion on what happened. Regarding prejudice, the
    prosecution asserted the animation would not show highly
    emotional details of the crime, such as the victims’ facial
    expressions and Winnie the Pooh paraphernalia. At the trial
    court’s request, the prosecution played and narrated the
    animation for the court. The trial court found the animation to
    be admissible demonstrative evidence to the extent it
    represented only the prosecution expert’s proposed testimony.
    Because Englert could not confirm whether Christopher’s eyes
    were open during the shootings, the trial court ordered the
    prosecution to show them closed in the animation. The trial
    court also required Englert to provide a declaration confirming
    60
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    that the final version of the animation depicted his
    understanding of the evidence. The prosecution shared a copy
    of the final version of the animation with the defense.
    The computer animation was presented to the jury in eight
    scenes during expert testimony by Englert, who spoke after each
    scene. The animation featured three-dimensional, mannequin-
    like recreations designed with relevant details, such as clothing
    and hair. Englert testified that the animation illustrated his
    opinion of how the shootings had to occur to produce the
    bloodstain patterns on the clothing that Caro was found wearing
    the night of the shootings. The court also delivered a cautionary
    instruction about the animation to the jury multiple times over
    the course of trial.6
    6
    One of these instructions read: “This is an animation
    based on an expert’s opinion. [¶] The computer animation we
    have here is nothing more than that, an illustration of the
    expert’s opinion. You are instructed to treat it no differently
    than you would any chart or diagram of the evidence. [¶] The
    animation is not intended to be a film of what actually occurred,
    nor is it an exact re-creation. Therefore, there may be facts that
    are not exactly accurate or not exactly as they occurred but may
    be reasonably close. [¶] It is important to keep in mind that an
    animated video is not an actual film of what occurred, nor is it
    intended to be an exact, detailed replication of every detail of
    every event or every movement. It is only an aid to giving you
    an overall view of the particular version of the events, based on
    particular viewpoints or particular interpretations of evidence
    made by an expert witness. [¶] . . . In determining what weight
    to give to any opinion expressed by an expert witness, you
    should consider the qualifications and believability of the
    witness, the facts and materials upon which each opinion is
    based, and the reasons for each opinion. . . .”
    61
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    We allow the admission of a computer animation as
    demonstrative evidence of expert testimony, but only if certain
    conditions are met. The animation must accurately depict an
    expert opinion, the expert opinion must fairly represent the
    evidence, the trial court must provide a proper limiting
    instruction, and the animation must be otherwise admissible
    under Evidence Code section 352. (See Duenas, supra, 55
    Cal.4th at pp. 20-25.) Caro contends the computer animation
    here is inadmissible under section 352. We disagree.
    Evidence Code section 352 provides that a court “may
    exclude evidence if its probative value is substantially
    outweighed by the probability that its admission will (a)
    necessitate undue consumption of time or (b) create substantial
    danger of undue prejudice, of confusing the issues, or of
    misleading the jury.” Caro argues that unlike in Duenas, where
    the cause of death was in dispute, the animation here is only
    minimally probative because only identity was disputed at trial.
    But Caro forgets that the animation had more than minimal
    probative value on the issue of identity. The animation
    illustrated the expert’s opinion that the blowback of blood from
    a gunshot to Christopher’s head was consistent with the
    bloodstain patterns on Caro’s, not Xavier’s, clothes.
    It is true that courts must be mindful of the powerful
    impact computer animations may have on jurors. The potential
    for such impact does not, however, create “an unjustified ‘air of
    technical and scientific certainty’ ” if accompanied by proper
    limiting instructions. (Duenas, supra, 55 Cal.4th at p. 23.) The
    trial court gave such limiting instructions here. They informed
    the jury that the animation merely illustrated the expert’s
    opinion, it did not exactly recreate the events on the night of the
    shootings, and it was the jury’s role to evaluate the expert’s
    62
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    opinion and its factual basis. While Caro argues that these
    cautionary instructions were ambiguous as to the animation’s
    purpose, the instructions were quite clear: They stated that the
    animation was an aid for understanding an expert’s opinion.
    Further, the content of the computer animation is not
    itself so graphic that prejudice arising from those details
    substantially outweighs the animation’s probative value. The
    animation featured mannequin-like representations of
    Christopher and Michael, with some facial features, hair, and
    clothing. The animation showed each gunshot fired, and the
    pattern of blood distribution after the gunshots, which was
    necessary to depict Englert’s testimony. It featured only one
    personal possession of the children, a doll on the side of the bed
    that Christopher’s blood had dripped on. While a slow-motion
    visual depiction of two killings is indeed disturbing, the
    animation did not include highly emotional details, such as
    graphic images of the damage wrought by the bullet entry
    wounds, the children’s facial expressions, or other superfluous
    elements to tug on the heartstrings of the jury. (See People v.
    Hood (1997) 
    53 Cal.App.4th 965
    , 972.)
    Caro also argues the animation was prejudicial because it
    was cumulative of other evidence. But in Duenas, we rejected a
    similar argument because it “misapprehend[ed] the animation’s
    role as demonstrative evidence. The animation was not offered
    as substantive evidence, but as a tool to aid the jury in
    understanding the substantive evidence.” (Duenas, supra, 55
    Cal.4th at p. 25.) Here, the animation is similarly not
    cumulative, as it is demonstrative evidence illustrating expert
    testimony — such demonstrative evidence provides
    noncumulative value over the testimony itself by encapsulating
    what may otherwise be a confusing series of events. Because
    63
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    whatever prejudice arising from the computer animation did not
    substantially outweigh its probative value, we conclude the trial
    court did not abuse its discretion.
    vii.     Prosecutorial Misconduct
    Caro argues that the prosecution committed misconduct
    by making certain statements in the closing arguments of the
    guilt and penalty phases of trial. Under California law, to
    establish reversible prosecutorial misconduct a defendant must
    show that the prosecutor used “ ‘deceptive or reprehensible
    methods’ ” and that it is reasonably probable that, without such
    misconduct, an outcome more favorable to the defendant would
    have resulted. (People v. Riggs (2008) 
    44 Cal.4th 248
    , 298
    (Riggs).)     A prosecutor’s misconduct violates the federal
    Constitution if the behavior is “ ‘so egregious that it infects the
    trial with such unfairness as to make the conviction a denial of
    due process.’ ” (People v. Redd (2010) 
    48 Cal.4th 691
    , 733
    (Redd).) To preserve a claim of prosecutorial misconduct for
    appeal, a defendant must object and request an admonition.
    (E.g., id. at p. 734; People v. Hill (1998) 
    17 Cal.4th 800
    , 820.) An
    exception exists where the objection and request for admonition
    would have been “futile or ineffective.” (Riggs, at p. 298.)
    a. Guilt Phase Closing Argument
    Caro contends that the prosecutor committed five
    instances of misconduct during closing arguments of the guilt
    phase. To establish misconduct, Caro must show “ ‘a reasonable
    likelihood the jury construed the remarks in an objectionable
    fashion.’ ” (Potts, supra, 6 Cal.5th at p. 1036.)
    First, Caro argues that the prosecutor improperly vouched
    for Xavier’s truthfulness by asserting that he was “honest” and
    that he “testified truthfully.” But Caro failed to object to these
    64
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    statements and request an admonition, so the claim is forfeited.
    (Riggs, 
    supra,
     44 Cal.4th at p. 298.) Moreover, any misconduct
    was harmless. The comments were brief, and several were
    “followed immediately by references to evidence bearing on
    witness credibility.” (People v. Sully (1991) 
    53 Cal.3d 1195
    ,
    1236.) The substantial physical evidence against Caro also
    corroborated Xavier’s version of events over hers. And both
    parties and the trial court’s instructions repeatedly emphasized
    to the jury that witness credibility was solely theirs to decide.
    Under these circumstances, there is no reasonable probability
    that the prosecutor’s comments affected the outcome.
    Second, Caro argues that the prosecutor committed
    misconduct by describing Xavier as “stifl[ing] sobs” and
    “crumpl[ing] over in pain” during his testimony. The statement,
    she contends, was impermissible because these physical cues
    are not in the record. Because defense counsel did not object or
    request an admonition on this issue, the claim is forfeited.
    (Redd, 
    supra,
     48 Cal.4th at p. 746.) Moreover, there was no
    misconduct. The demeanor of a witness is “rarely reflected in
    the record” (People v. Navarette (2003) 
    30 Cal.4th 458
    , 516), but
    is a proper factor for the jury to consider when assessing the
    witness’s credibility (People v. Jackson (1989) 
    49 Cal.3d 1170
    ,
    1205-1206; see also Evid. Code, § 780, subd. (a)).
    Third, Caro contends that the prosecutor improperly
    expressed a personal opinion in closing argument. She said,
    “And Deputy Tutino heard [Xavier] say again and again, ‘She
    killed my best friend. She killed my best friend.’ [¶] You know
    that [Xavier] was talking about Joey. Like any father [Xavier]
    would want to believe that he loved all of his children equally.”
    She then began to say, “I’m sure he did a great job making each
    child feel loved and feel — ” when defense counsel objected on
    65
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    the ground that the prosecutor was expressing a personal
    opinion, and the trial court sustained the objection.
    The prosecutor then went on to argue the following: “But
    as difficult as it is to say, you can tell from the state of the
    evidence that [Xavier] had a special place for Joey. Joey was the
    one who made [Xavier] a father for the first time. Joey was the
    one who was most like a person. He was the oldest at the time.
    [¶] And when [Xavier] sat there in his family room saying, ‘She
    killed my best friend,’ he was talking about Joey. That’s
    probably why he was the defendant’s first target.” Caro asserts
    this second statement, too, was the prosecutor’s own opinion and
    not permissible argument on the evidence.
    As to the first statement about making each child feel
    loved, counsel objected but did not request an admonishment.
    As to the second statement, Caro did not object. Both omissions
    forfeit any challenge to these statements. (Riggs, supra, 44
    Cal.4th at p. 298.) And the alleged misconduct was, in any
    event, so minimal as to have no reasonable probability of
    affecting the outcome.
    Fourth, Caro asserts that the prosecutor improperly relied
    on facts not in evidence by arguing that Sergeant Timothy
    Lorenzen was the lead investigator but was not called in the
    prosecution case because he only had a limited set of duties.
    Caro argues that this was an improper way to explain the reason
    why the prosecution did not call Lorenzen to testify, and that
    the actual reason was that he was impeachable for cheating on
    an exam. But Caro failed to object to the argument regarding
    Lorenzen at trial; so the claim is forfeited. (Riggs, 
    supra,
     44
    Cal.4th at p. 298.) Plus, any error was harmless because the
    66
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    reason for not calling Lorenzen was a tangential, minor issue
    that would not have affected the outcome of the case.
    Fifth, Caro argues the prosecutor improperly insulted the
    role of the defense by arguing that the prosecution’s burden was
    to “prove to 12 jurors beyond a reasonable doubt the truth of the
    allegations against a defendant,” while all the defense had to do
    was “confuse one of you.” The prosecutor went on to say, “That’s
    the tactic that many defense attorneys employ. Confusion.
    Throw up smoke. Try and mislead jurors. And maybe, by
    chance, they’ll get lucky and get one.” The prosecutor later said,
    “I just ask that you not be the one that the defense is trying to
    target for confusion.” Caro failed to object to this argument, so
    the claim is forfeited. (Riggs, supra, 44 Cal.4th at p. 298.) In
    any event, we do not forbid prosecutors from arguing that the
    defense case seeks to confuse the jury. (See People v. Kennedy
    (2005) 
    36 Cal.4th 595
    , 626.) And the prosecutor was permitted,
    as she did immediately after these statements, to “highlight the
    discrepancies between [defense] counsel’s opening statement
    and the evidence.” (People v. Bemore (2000) 
    22 Cal.4th 809
    ,
    847.) We find no misconduct under these circumstances.
    b. Penalty Phase Closing Argument
    Caro contends — in a summary bullet-point list — that the
    prosecutor committed 15 instances of misconduct during the
    penalty phase closing argument. Given the summary nature of
    her contentions, Caro fails to assert precisely why the
    statements were misconduct or cite relevant authority. She also
    does not argue how these statements prejudiced her, except by
    asserting that all of the prosecutorial misconduct claims were
    cumulatively prejudicial. The failure to “ ‘offer any authority or
    argument in support of [her] claim[s]’ ” would justify us
    67
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    “declin[ing] to address these contentions.” (People v. Foster
    (2010) 
    50 Cal.4th 1301
    , 1352 (Foster).) Regardless, Caro
    concedes that defense counsel did not object to the following
    statements, thus forfeiting her claim: (1) the assertion that
    Christopher was trying to “get away from his killer” and was
    “fighting . . . for his life”; (2) the assertion that Christopher
    “saved [G.C.]’s life by making her shoot [Christopher] twice,
    using up the bullet that was probably meant for [G.C.]”; (3) the
    statement that “[a]ll murders are committed when people are
    going through bad times in their lives”; (4) descriptions in the
    penalty phase of Xavier’s testimony as truthful or honest; and
    (5) statement’s that the dead children “would have been
    successful” and “would have been wonderful.” (Riggs, supra, 44
    Cal.4th at p. 298.)
    For the following statements, Caro objected but failed to
    request an admonition: (1) the prosecutor asked the jury to cry
    for the boys; (2) the prosecutor misstated the law by asserting
    that every factor in the penalty phase must be proven beyond a
    reasonable doubt (and the jury instructions later stated the
    correct standard); (3) the prosecutor stated that the defense had
    “chang[ed] [its] story” in the penalty phase; (4) the prosecution
    referred to a witness as a “bought-and-paid-for defense expert”;
    and (5) the prosecution argued Caro was not someone who
    “wound up selling dope at age twelve to put food in her mouth,
    getting hooked on drugs.” That failure forfeits her claims. (Duff,
    supra, 58 Cal.4th at p. 567.) With regard to the final statement
    about getting “hooked on drugs,” Caro points out that the
    prosecutor continued by arguing that Caro was not “a poor
    inner-city kid who never had a chance.” But Caro failed to object
    or request an admonition as to that subsequent statement,
    forfeiting the claim. (Riggs, 
    supra,
     44 Cal.4th at p. 298.)
    68
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Moreover, any potential misconduct in these statements was
    ultimately harmless.
    Caro also raises a number of claims where the trial court
    overruled objections or rejected requests for admonitions. First,
    Caro contends that the prosecutor relied on facts not in evidence
    when she argued, “This defendant’s situation is really not that
    much different from other people who are facing difficult
    relationships or failed marriages. [¶] In fact, hers was a lot
    better.” The prosecutor continued, “The only real emotional
    disturbance or strain that separates this defendant from any
    other woman or any man who’s facing a failing marriage is her
    vanity. Her pride. . . .” Caro objected, and the trial court
    overruled the objection. We find no misconduct. These
    references to how other women react to similar circumstances
    draws on “ ‘common knowledge’ ” or “ ‘common experiences.’ ”
    (People v. Mendoza (2016) 
    62 Cal.4th 856
    , 908.)
    Second, the prosecutor incorrectly argued to the jury that
    appellant’s toxicology screen did not test positive for Xanax. The
    trial court overruled a defense objection. But no possible
    prejudice arose from this statement because the prosecutor
    subsequently admitted its mistake to the jury, and the parties
    stipulated to the presence of Xanax in Caro’s bloodstream.
    Third, the prosecutor argued that the trial court could
    consider sympathy for Caro in mitigation, but not sympathy for
    her family. Defense counsel objected on the ground that this
    was a misstatement of law, and the trial court overruled Caro’s
    objection. The prosecutor did not misstate the law. (See People
    v. Ochoa (1998) 
    19 Cal.4th 353
    , 456 (Ochoa); see also People v.
    Rices (2017) 
    4 Cal.5th 49
    , 87-89.) Caro’s citation to Cullen v.
    Pinholster (2011) 
    563 U.S. 170
     is unavailing because it was an
    69
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    ineffective assistance of counsel case based on a 1984 trial,
    before we held in Ochoa that the jury could not consider
    sympathy toward a defendant’s family in mitigation.
    (Pinholster, at pp. 176, 191.)      This argument was not
    misconduct.
    Fourth, the prosecutor told the jurors to imagine
    themselves as Christopher in bed, feeling safe, before he was
    shot by Caro. Caro’s objection was overruled. This argument
    was not misconduct. It is not improper for a prosecutor to “invite
    the jurors to put themselves in the place of the victims and
    imagine their suffering.” (People v. Slaughter (2002) 
    27 Cal.4th 1187
    , 1212.)
    Finally, the prosecutor stated that Caro “slaughtered” the
    boys. Caro failed to object, but later requested the jury be
    admonished that the term “slaughter” was improper. The trial
    court refused. This statement was not misconduct because the
    word “slaughter” is a fair description of what happened to the
    children — the killer shot three children in the head, in their
    beds, at point-blank range. The prosecutor is, to a point, allowed
    to use “colorful language to explain the prosecutor’s view of the
    evidence.” (People v. Rundle (2008) 
    43 Cal.4th 76
    , 163 (Rundle).)
    On the facts of this case, saying “slaughter” was not misconduct.
    In addition, Caro contends that defense counsel’s failure
    to object or request an admonition to the above statements
    constituted ineffective assistance of counsel under Strickland.
    But we regularly reject such claims on direct appeal where, as
    here, the record sheds no light on why defense counsel failed to
    object or request an admonition. (People v. Gray (2005) 
    37 Cal.4th 168
    , 207.) This is not the rare case where there “could
    be no satisfactory explanation” for the failure to object or request
    70
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    admonitions, which may have arisen from a desire not to call
    attention to the allegedly faulty arguments. (Ibid.) The failure
    to object only rarely constitutes ineffective representation.
    (Ibid.) And Caro fails to demonstrate that the exclusion of the
    statements would have, with a reasonable probability, changed
    the outcome. We therefore reject Caro’s ineffective assistance of
    counsel claim.
    viii.   Penalty Phase Factor (b) Evidence
    Caro argues that there was insufficient evidence to allow
    admission of her prior criminal acts at the penalty phase of trial,
    and that the evidence presented was insufficiently specific to
    give Caro a fair opportunity to defend against the accusations
    concerning those acts. As a result, she contends that the
    evidence of prior acts violated her right to due process, to
    confront and cross-examine witnesses against her, and to a
    reliable determination of penalty under the Sixth, Eighth, and
    Fourteenth Amendments.
    Section 190.3, factor (b) allows the jury to consider as
    aggravation evidence “[t]he presence or absence of criminal
    activity by the defendant which involved the use or attempted
    use of force or violence or the express or implied threat to use
    force or violence.” To present such evidence at trial, the
    prosecution must provide the defendant notice of the evidence
    to be introduced and the opportunity to confront the available
    witnesses. (People v. Yeoman (2003) 
    31 Cal.4th 93
    , 136-137; see
    also Rundle, 
    supra,
     43 Cal.4th at p. 183.) Additionally, to
    consider this evidence in aggravation, the jury must be
    convinced beyond a reasonable doubt that Caro committed these
    prior acts. (Yeoman, at p. 137.) If these three requirements are
    satisfied, the jury may consider a defendant’s prior criminal acts
    71
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    without violating his or her rights to due process, a speedy trial,
    or a reliable penalty determination. (Id. at p. 136.) The
    remoteness of the prior criminal acts then affects their weight
    in aggravation rather than their admissibility. (Id. at p. 137.)
    Caro first asserts that the notice given to her about the
    evidence to be presented, and the evidence eventually
    presented, deprived her of notice of the allegations and an
    opportunity to present a meaningful defense. For many of the
    seven prior acts presented in the penalty phase, the notice and
    testimony did not identify the specific timeframe when the event
    occurred. We rejected a similar claim in Rundle where the
    defendant argued that the section 190.3, factor (b) evidence
    relating to the defendant’s ex-wife amounted merely to a
    “nonspecific series of acts occurring over a period of several
    months, without providing exact dates upon which specific acts
    of forcible sodomy or oral copulation occurred.” (Rundle, supra,
    43 Cal.4th at p. 182.) We held that the relevant inquiry is
    whether the three requirements set forth in Yeoman are
    satisfied. (See Rundle, at pp. 183-186 [requiring less notice of
    timeframes in penalty phase where the point is the evaluation
    of the defendant’s character, not the establishment of a
    particular act].) Here, Caro had notice of the incidents at issue
    and evidence to be presented against her and had the
    opportunity to cross-examine witnesses. Moreover, defense
    counsel asserted the incidents would be “disputed and
    contested,” the credibility of the witnesses would be “vigorously
    attacked,” and “there are some very significant defenses to acts
    [the prosecution] claimed occurred.”         The jury was also
    instructed to only consider the evidence in aggravation if it
    found the prior acts true beyond a reasonable doubt. Our
    precedent does not require more. (See ibid.)
    72
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Caro also contends that there was insufficient evidence for
    the jury to conclude beyond a reasonable doubt that many of the
    incidents occurred because they were supported only by Xavier’s
    uncorroborated testimony. We have previously rejected similar
    claims based on a witness’s lack of trustworthiness in the section
    190.3, factor (b) context. (People v. Stitely (2005) 
    35 Cal.4th 514
    ,
    564.) Rather than rendering factor (b) evidence inadmissible,
    the untrustworthiness of a witness’s testimony goes to its weight
    and can be shown through cross-examination and other
    evidence. (Rundle, 
    supra,
     43 Cal.4th at pp. 184-185.) Neither
    the lack of specific dates nor the character of the evidence
    presented caused the evidence to be insufficient as a matter of
    law. (Id. at p. 185.)
    Caro requests we require trial courts to hold hearings to
    determine whether the evidence is sufficient for a jury to find a
    prior violent offense beyond a reasonable doubt. Trial courts
    have discretion to hold such a hearing. (See People v. Phillips
    (1985) 
    41 Cal.3d 29
    , 72, fn. 25; see also People v. Friend (2009)
    
    47 Cal.4th 1
    , 87; People v. Fauber (1992) 
    2 Cal.4th 792
    , 849.)
    Caro argued here that a hearing was necessary because she
    planned to impeach the prosecution’s evidence and present
    defenses. But the trial court did not abuse its discretion by
    finding the prosecution’s proffered evidence sufficient without a
    hearing and allowing the jury to evaluate the defense response.
    And to the extent Caro argues that the probative value of the
    prior act evidence was not substantially outweighed by undue
    prejudice under Evidence Code section 352, that claim fails. The
    trial court did not abuse its discretion by finding that these prior
    acts were not “particularly prejudicial” in comparison to the
    offense of conviction, especially under the somewhat
    circumscribed Evidence Code section 352 analysis for Penal
    73
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Code section 190.3, factor (b) evidence. (People v. Box (2000) 
    23 Cal.4th 1153
    , 1201.)
    Finally, Caro asks us to reconsider Rundle because of the
    danger that jurors will credit vague, uncorroborated prior acts
    when introduced with more specific, corroborated prior acts.
    But we perceive no such danger where jurors receive
    instructions to only consider a prior act in aggravation if proven
    beyond a reasonable doubt. Because the requirements in
    Yeoman and Rundle were satisfied, we reject Caro’s section
    190.3, factor (b) claim.
    C. Juror Misconduct and Related Motion for New
    Trial
    i.   Dismissal of Juror During Deliberations
    Caro argues that the trial court erred by dismissing Juror
    No. 9 for his statements to Juror No. 11 outside of the
    deliberation room. In the alternative, Caro argues that if there
    was sufficient evidence for Juror No. 9’s dismissal, then the trial
    court should have also dismissed Juror No. 11, who was part of
    the conversation with Juror No. 9. Caro also contends that the
    trial court erred by failing to grant a new trial based on the
    jurors’ posttrial declarations about their conversation.
    On November 2, 2001, the jury foreperson submitted a
    note to the trial court stating that one of the jurors was a holdout
    who was refusing to deliberate. Because this note came on a
    Friday, the trial court decided to excuse the jury and conduct an
    inquiry the following Monday. But before excusing the jury, the
    trial court admonished the jury: “I need to give you the
    admonition you’ve heard so many times before, but you need to
    hear it again. [¶] And that is you cannot discuss this case
    outside the presence of the jury room with the other 11 or 12
    74
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    jurors. . . . You’re not to deliberate upon the case any further
    during the weekend, and the only time you can discuss the case,
    deliberate the case is when you’re back in the jury room Monday
    and all 12 jurors are present in the jury room.”
    The following Monday, the trial court called in the jury
    foreperson, who indicated that the juror at issue was no longer
    refusing to deliberate. The parties did not pursue the issue
    further. But defense counsel also raised a new issue discovered
    by a defense investigator, who saw Juror No. 9 and Juror No. 11
    speaking in the parking lot the previous Friday evening after
    the jury was excused. Defense counsel requested an inquiry.
    The trial court first examined Juror No. 9. When asked
    whether there was any discussion about the case between Juror
    No. 9 and Juror No. 11, Juror No. 9 said, “There was. There was
    one line, I think. One or two lines. That’s correct.” When the
    trial court asked Juror No. 9 to describe the discussion he
    related the following: “The comment which was discussed
    between myself and the one juror only . . . was in regards to the
    emotionalism of what was going on in the jury room and the fact
    that emotions were very highly charged. [¶] We were — there
    was some personal stuff said, which made it difficult for
    deliberations to take place, and there was also a comment in
    regards to the personal — or not personal, excuse me, in regards
    to the emotional state, which sounds really bad, but it was — in
    fact, the exact quote was in regards to the defendant. And it
    would have been ‘she had to be emotional on that night.’ And
    my response to that was that I agree.” Juror No. 9 said that was
    the only discussion of the case. When asked whether Juror No.
    9 or Juror No. 11 had initiated the conversation about the case,
    Juror No. 9 said, “It very well could be me, sir,” but he could not
    remember. Juror No. 9 remembered telling Juror No. 11
    75
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    regarding the deliberations that “it’s not productive when
    people’s tempers get so flared up they start to use personal
    attacks and stuff like that.”
    The trial court then called Juror No. 11. When asked
    whether the case was discussed in the parking lot, Juror No. 11
    said, “Not specifically, no.” When asked whether they spoke
    about the deliberations, Juror No. 11 said, “Sort of.” Juror No.
    11 explained, “Basically, he thanked me for taking the time to
    listen . . . and to understand his perspective of things.” Juror
    No. 11 indicated this was the only discussion about the case and
    that she did not advocate for Juror No. 9 to do anything during
    the deliberations.
    Defense counsel requested the discharge of Juror No. 9
    because he “knowingly and willingly violated” the trial court’s
    specific orders and “attempted to engage another juror in
    discussions about the emotional state of Mrs. Caro” in order to
    “convince her of his position . . . .” Defense counsel argued, “I
    want [Juror No. 9] off. He’s deliberately and intentionally
    violated his oath as a juror. I just couldn’t be more concerned
    about it.” The prosecution agreed to the removal of Juror No. 9
    so long as Caro personally consented to the discharge, and Caro
    consented. The trial court then discharged Juror No. 9, finding
    “good cause” because of his “flagrant violation of the court’s
    order regarding discussing the matter outside the presence of
    the jury room with another juror and discussing subject matter
    that is indeed in the court’s opinion deliberations on evidence
    received in this case.”
    The trial court then invited the parties “to raise any issues
    regarding Juror No. 11.” The prosecutor raised concerns about
    removing Juror No. 9, but not Juror No. 11, if there was “two-
    76
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    way participation” in the parking lot conversation. Defense
    counsel and the prosecutor agreed that they did not hear
    evidence that Juror No. 11 had made a comment about Caro’s
    emotional state on the night of the shootings. Defense counsel
    also stated that Juror No. 11 seemingly did not understand that
    Juror No. 9 was attempting to gain support for his position, and
    that “she didn’t offer any information about the case or discuss
    any of the facts of the case.” The trial court agreed, and
    explained, “I took [Juror No. 11]’s comments to be it was [Juror
    No. 9] who was the initiator of the conversation and [Juror No.
    11] was kind of stuck and being nice.” The trial court stated it
    was not finding that Juror No. 11 discussed the case and noted
    that “no one is asking to excuse Juror No. 11. I presume if the
    parties felt there was something inappropriate in what she said,
    I would have heard it by now.” After a recess, the trial court
    stated that it “was satisfied that nothing has occurred that
    would jeopardize [Juror No. 11]’s ability to continue to be a fair,
    impartial juror for both sides.” The trial court asked the parties
    if they wanted to be heard, and neither defense counsel nor the
    prosecutor requested that Juror No. 11 be removed.
    Following the penalty phase verdict, Caro filed a motion
    for new trial. Among other issues, Caro contended, through a
    declaration from Juror No. 9, that Juror No. 11 should have been
    removed for misconduct. Juror No. 9 declared that he and Juror
    No. 11 had “continued with the conversations that we had
    started in the deliberation room” as they walked to their cars,
    and that he did not remember who “initiated the topic of the
    deliberations or trial.” Juror No. 9 wrote that he told Juror No.
    11 that he “appreciated that she discussed the case calmly
    without flying into a tantrum as others had done” and that there
    was “mutual discussion revolving around the events that took
    77
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    place that day.” According to Juror No. 9, they went on to
    discuss Caro’s state of mind. Juror No. 9 “made the point that
    Cora was of the opinion that her husband was going to leave her
    and the boys. He had done it before and he was just going to do
    it again. The e-mails and interviews showed this. . . . This
    might cause us to question the motive presented by the
    prosecution.” According to Juror No. 9, Juror No. 11 said that
    this “ ‘was just the last straw for Cora,’ ” that Xavier was going
    to leave her again, and this time Caro could not stand it. Juror
    No. 11 then said “in a raised voice with some animation in the
    arms, ‘Well [Juror No. 9], you know she had to be emotional that
    night.’ ”
    The prosecution submitted a declaration from Juror No.
    11.    She stated, “On the evening of the fourth day of
    deliberations, [Juror No. 9] and I walked to our cars together in
    the parking lot. [Juror No. 9] brought up the topic of the
    deliberations.    He made comments about how difficult
    deliberations were, and that the deliberations had gotten
    personal. He stated that the deliberations had become too
    emotional. I said something to the effect of, ‘Well it had to be an
    emotional night, so it’s understandable that we’re emotional in
    there.’ ” Juror No. 11 also denied waving her arms when making
    this statement, referencing Caro’s mental state on the night of
    the shootings, or discussing any of the evidence related to the
    case.
    The trial court denied Caro’s motion for new trial. It
    expressed general agreement with the prosecution’s argument,
    which included an assertion that Juror No. 11’s declaration,
    rather than Juror No. 9’s declaration, accurately represented
    the events in the parking lot. The trial court then found that
    Juror No. 9’s declaration did not differ substantially from the
    78
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    statements uncovered in the inquiry at trial, and that Juror No.
    11’s declaration was consistent with what the court uncovered
    in the inquiry. The trial court noted that neither party
    requested Juror No. 11’s discharge and that it was now
    “disingenuous” for the defense to assert that Juror No. 11
    committed misconduct. The trial court also found that, if there
    was misconduct, it was not “inherently and substantially likely
    to have influenced” Juror No. 11, and it was not “substantially
    likely” that she was biased against Caro because of the
    conversation. The trial court later found that, in general, Juror
    No. 9 “infers motive or intent or conduct which a better factual
    analysis would not show that that was the import of that
    statement or the intent of the conduct or the motive of the
    person who made the statement.” The trial court characterized
    this as, to some extent, a credibility finding with respect to Juror
    No. 9, who “just assumes things and perhaps believes them to
    be accurate when in fact a further analysis would reveal they’re
    not accurate.”
    Regarding the dismissal of Juror No. 9, Caro has waived
    her claim of error. Defense counsel affirmatively sought to
    discharge Juror No. 9 because the juror committed intentional
    misconduct. She did not seek a mistrial based on Juror No. 9’s
    discharge. Having forcefully argued for Juror No. 9’s dismissal,
    Caro cannot now complain that the trial court erred in siding
    with her. (See People v. Coffman (2004) 
    34 Cal.4th 1
    , 49 [counsel
    invited error by affirmatively challenging juror]; People v.
    Cunningham (2001) 
    25 Cal.4th 926
    , 1029 [claim of improper
    juror discharge waived where “defense counsel not only did not
    object to the substitution of the juror or move for a mistrial, but
    sought to have her excused”].)
    79
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Caro argues in the alternative that if the claim was
    forfeited, defense counsel’s choice to seek Juror No. 9’s removal
    constituted ineffective assistance of counsel. But Caro must
    show that her counsel’s performance was deficient, that is,
    counsel’s performance must fall “ ‘ “below an objective standard
    of reasonableness [¶] . . . under prevailing professional
    norms.” ’ ” (Lopez, supra, 42 Cal.4th at p. 966.) It is undisputed
    that Juror No. 9 committed misconduct. Without a more
    compelling argument, it is difficult to conclude a lawyer’s
    attempt to remove a juror who clearly committed misconduct —
    an attempt to preserve the integrity of the jury — constitutes
    constitutionally deficient performance. Regardless, there may
    have been plausible strategic reasons for seeking Juror No. 9’s
    removal that are not apparent on direct appeal. (Ochoa, supra,
    19 Cal.4th at p. 445; People v. Mendoza Tello (1997) 
    15 Cal.4th 264
    , 266.) So we cannot conclude that seeking to remove Juror
    No. 9 constituted deficient performance.
    Caro next contends that even if the trial court was right to
    remove Juror No. 9, it should have also removed Juror No. 11
    because she was equally culpable. To the extent Caro argues
    that the trial court should have removed Juror No. 11 during
    trial, defense counsel’s failure to object or request a mistrial
    forfeited that argument. (See People v. Williams (2013) 
    58 Cal.4th 197
    , 289 (Williams); Foster, 
    supra,
     50 Cal.4th at pp.
    1340-1341; People v. Stanley (2006) 
    39 Cal.4th 913
    , 950.) And
    to the extent Caro raises an ineffective assistance of counsel
    claim for not seeking Juror No. 11’s dismissal, even assuming
    there was good cause for such a dismissal, the record is
    insufficient to evaluate trial counsel’s tactical choice. (See
    People v. Mendoza Tello, 
    supra,
     15 Cal.4th at p. 266.)
    80
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    Nonetheless, Caro brought a new trial motion arguing
    that a declaration of Juror No. 9 showed that Juror No. 11
    committed misconduct. We only disturb a trial court’s decision
    on a motion for new trial if the ruling constitutes “a manifest
    and unmistakable abuse of . . . discretion.”             (People v.
    Thompson, supra, 49 Cal.4th at p. 140.) If the motion is based
    on juror misconduct, we accept the trial court’s factual findings
    and credibility determinations if supported by substantial
    evidence, but exercise “independent judgment” to determine
    whether the misconduct was prejudicial. (People v. Dykes (2009)
    
    46 Cal.4th 731
    , 809 (Dykes).) Juror misconduct raises a
    presumption of prejudice. Still, we evaluate the entire record to
    determine if, on the whole, there was a “ ‘substantial
    likelihood’ ” of prejudice in the form of “ ‘actual[] bias[] against
    the defendant.’ ” (In re Boyette (2013) 
    56 Cal.4th 866
    , 890, italics
    omitted.)
    As an initial matter, the trial court found that Juror No.
    9’s declaration did not substantially differ from the evidence at
    trial. Although some differences existed — Juror No. 9 asserted
    a longer, heated conversation than what he testified to at
    trial — the trial court’s finding that there was no substantial
    difference makes sense in light of its credibility determinations
    about Juror No. 9. The trial court agreed generally with the
    prosecution’s arguments on the motion for a new trial, which
    included an assertion that Juror No. 11’s, rather than Juror No.
    9’s, declaration was accurate, and the trial court later found that
    Juror No. 9 lacked credibility. The trial court’s findings
    implicitly rejected the additional details Juror No. 9 included in
    his declaration and showed acceptance of Juror No. 11’s version
    of events, which comported with the evidence at trial. Caro
    argues that Juror No. 11’s declaration differed from her trial
    81
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    court statement, because she did not previously mention that
    she had told Juror No. 9 it had to be “an emotional night.” But
    the declaration was consistent with Juror No. 9’s statement at
    trial that he had “agreed” with Juror No. 11’s assertion that
    “ ‘[Caro] had to be emotional on that night.’ ” Although Juror
    No. 9’s earlier account indicated that Juror No. 11 may have
    spoken about Caro’s emotional state, and Juror No. 11’s
    declaration contained a more general statement about an
    “emotional night,” the trial court clearly felt that Juror No. 9
    lacked credibility, so this minor difference does not make the
    later declaration inconsistent. We conclude the trial court’s
    finding — that there was no substantial difference in the
    declarations’ versions of events — was supported by substantial
    evidence.7
    As a result, the trial court found that any juror misconduct
    was not inherently and substantially likely to have influenced
    Juror No. 11, and it was not substantially likely that she was
    biased against Caro because of the parking lot conversation. We
    find no abuse of discretion. The trial court found at trial that
    Juror No. 9 initiated a conversation with Juror No. 11 who “was
    kind of stuck and being nice.” And the trial court implicitly
    7
    The lack of credible new evidence alone may have been
    sufficient to deny the motion for new trial, given defense
    counsel’s failure to object to, and her approval of, Juror No. 11’s
    presence on the jury. (Foster, supra, 50 Cal.4th at p. 1341; cf.
    People v. Cowan (2010) 
    50 Cal.4th 401
    , 486; Cowan v. Superior
    Court (1996) 
    14 Cal.4th 367
    , 392; Weathers v. Kaiser Foundation
    Hospitals (1971) 
    5 Cal.3d 98
    , 103. But see People v. Adame
    (1973) 
    36 Cal.App.3d 402
    , 410.) Nonetheless, the trial court
    merely stated it was “disingenuous” to raise the new trial motion
    without new evidence and did not rule based on that fact. We
    do the same.
    82
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    affirmed that finding by indicating that neither of the posttrial
    declarations altered its perception of what had happened. Juror
    No. 11’s declaration thus supported the trial court’s
    understanding of what occurred. The trial court’s finding that
    Juror No. 11 was “kind of stuck and being nice” and the
    generalized, innocuous nature of her responsive statement to
    Juror No. 9 counters any implication that Juror No. 11 was
    actually biased against Caro. (See In re Boyette, supra, 56
    Cal.4th at p. 889; People v. Lewis (2009) 
    46 Cal.4th 1255
    , 1309.)
    Caro additionally contends that Juror No. 11 was actually
    biased because she did not disclose her statement that it had to
    be “an emotional night” at trial. But this precise theory of
    misconduct was never raised to the trial court, so is forfeited.
    (Dykes, 
    supra,
     46 Cal.4th at p. 808, fn. 22.) Moreover, Juror No.
    11 did disclose that they had “[s]ort of” discussed deliberations,
    and that Juror No. 9 had thanked her for listening to him during
    deliberations. Omitting this mostly innocuous comment in
    response to the judge’s question, “[D]id you discuss with him
    further about the deliberations?” may have been inadvertent
    and not misconduct. But to the extent it was misconduct, the
    trial court did not abuse its discretion by finding no actual
    bias — the omission was minor, and Juror No. 11 was candid in
    her declaration. (See People v. Lewis, 
    supra,
     46 Cal.4th at p.
    1309.)
    ii.   Posttrial and Pre-sentencing Destruction of
    Dismissed Jurors’ Notes
    Caro asserts that by destroying Juror No. 9’s notes after
    his dismissal, the trial court deprived Caro of evidence
    supporting claims of juror misconduct in her motion for a new
    trial and violated Government Code former section 68152,
    subdivision (e)(1). After the conclusion of the penalty phase, on
    83
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    February 1, 2002, Caro filed a motion for the release of Juror
    No. 9’s notes as evidence of prejudicial jury misconduct. At the
    hearing on the motion, the trial court indicated that it had no
    such notes. The bailiff testified that when Juror No. 9 was
    excused for juror misconduct, the bailiff told him that he could
    pick up the notes at the close of trial. The notes were kept in
    the jury room in the meantime. After the trial, Juror No. 9
    called the court twice and arranged times to pick up the notes
    but did not show up either time. The trial court judge was going
    to go on vacation for three weeks after these two dates, and the
    bailiff decided it would be best to destroy the notes rather than
    leave them in the courtroom. Because Juror No. 9 had failed to
    pick up the notes on the dates he said he would, the trial court
    agreed with the bailiff’s suggestion. The bailiff destroyed Juror
    No. 9’s notes (along with the notes for Alternate Juror No. 2 and
    Alternate Juror No. 5). The trial court’s standard practice was
    to destroy juror notes after trial.
    This practice did not violate any statutory or
    constitutional principles. Government Code former section
    68152, subdivision (e)(1) required the trial court to preserve
    “court records” on a permanent basis. (See Stats. 1998, ch. 931,
    § 236, pp. 6523-6524; id., ch. 932, § 34.5, p. 6816.) But the
    definition of “court records” found in Government Code former
    section 68151, subdivision (a) (Stats. 1996, ch. 1159, § 14, pp.
    8475-8476) and former section 68152, subdivision (j) (Stats.
    1998, ch. 931, § 236, pp. 6526-6527; id., ch. 932, § 34.5, pp. 6817-
    6818) does not mention juror notes. Instead those provisions
    refer to official documents of the kind that would be filed with
    the court or an administrative agency, not a juror’s informal
    notes on the trial. (See Gov. Code, former §§ 68151, subd. (a),
    68152, subd. (j); see also id., §§ 68151, subd. (a), 68152, subd. (g)
    84
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    [similar current version of these provisions].) And even
    assuming “court records” can be construed to include juror notes
    and that such notes are discoverable, Caro has failed to
    demonstrate any prejudice. Caro’s motion for new trial
    contained a declaration from Juror No. 9 and there is no
    evidence to indicate that Juror No. 9 was unable to remember
    his experiences during the trial. Accordingly, we deny Caro’s
    claim regarding the destruction of Juror No. 9’s notes.
    iii. Exclusion of Defense Witness on Motion for New
    Trial
    Caro argues the trial court erred by not allowing the
    defense to call certain witnesses at a hearing on the new trial
    motion. The prosecution submitted declarations from all 12
    jurors in its opposition to the defense’s motion. Juror No. 9’s
    declaration included the statement, “One day during
    deliberations, we asked the bailiff if we could see [a photograph
    of Xavier’s car leaving his office’s parking lot on the night of the
    shootings] projected on the wall and she stated that we could
    only have the evidence we already had back in the jury room.”
    The alleged request was never communicated to the parties. In
    a morning hearing, the court reported that the bailiff had
    informed the court such a request never occurred. Defense
    counsel requested to examine the bailiff, who testified that such
    a request was never made. Defense counsel then asked to call
    Juror No. 3 — the jury foreperson — to testify to what occurred,
    based on defense counsel’s “belie[f]” that Juror No. 3 would
    testify “that a conversation did take place with the bailiff
    regarding getting an additional item of evidence or an
    opportunity to view the photograph projected on the wall and
    that in fact a response was made.” The prosecution argued that
    such testimony was irrelevant because Juror No. 9 was later
    85
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    excused, causing deliberations to begin anew after the alleged
    request. The trial court observed that nothing in Juror No. 3’s
    declaration indicated he would provide material testimony on
    this issue. Based on the evidence the parties had provided so
    far, the court tentatively found the alleged request did not occur.
    The trial court stated it would permit the defense to provide
    additional submissions but emphasized its intention to resolve
    the matter that day.
    Later that day, defense counsel proffered written
    summaries of interviews with Juror No. 10 and Juror No. 9. The
    first allegedly stated that Juror No. 10 remembered Juror No. 9
    making some sort of request to the bailiff. The second allegedly
    indicated that Juror No. 2 remembered Juror No. 9 asking for a
    photograph of Xavier’s car and a note or sticker in the
    windshield of the car. Based on this proffer, defense counsel
    requested permission to file additional juror declarations,
    including the still-outstanding declaration anticipated from
    Juror No. 3, or, as an alternative, to call Jurors No. 9 and No. 10
    to the stand. The prosecutor asserted the new information was
    not specific enough to support further hearing on the matter and
    renewed her argument that the issue was irrelevant. The trial
    court agreed and denied the defense’s request to file additional
    declarations or call more witnesses. It faulted defense counsel
    for failing to timely submit any declarations after receiving
    permission to do so at the morning hearing.
    Caro asserts the requested testimony would have shown
    that the bailiff violated section 1138 by failing to notify counsel
    of the alleged request. The government argues, and Caro does
    not dispute, that Caro did not raise this purported violation as
    a basis for her new trial motion. The trial court could not have
    86
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    committed error by declining to take additional evidence on an
    issue irrelevant to the motion.
    Even assuming Caro’s motion incorporated the section
    1138 claim and that it was a cognizable ground for obtaining a
    new trial, she fails to show prejudice entitling her to relief. (See
    People v. Clair (1992) 
    2 Cal.4th 629
    , 667 [trial court may grant
    new trial motion only if the defendant demonstrates reversible
    error]; People v. Jenkins (2000) 
    22 Cal.4th 900
    , 1027 [“ ‘[a]
    conviction will not be reversed for a violation of section 1138
    unless prejudice is shown’ ”].) Suppose Caro’s proffered juror
    testimony convinced the court that Juror No. 9 had indeed
    requested the enlarged photo. Her theory of prejudice is that
    Juror No. 9 believed the timestamped photo did not in fact show
    Xavier’s car. Juror No. 9 therefore doubted the prosecutor’s
    timeline establishing Xavier’s whereabouts the night of the
    shootings. Had he been able to show other jurors a bigger image
    of the photo before the trial court discharged him for
    misconduct, at least one other juror might have shared his doubt
    about the timeline and the ultimate question of Caro’s guilt. But
    Caro offers no more than speculation that the projected photo
    would confirm Juror No. 9’s suspicions, that such confirmation
    had a reasonable likelihood of affecting jury deliberations after
    Juror No. 9’s departure, or that the photo mattered to any
    remaining juror.
    The trial court did not err in declining to hear additional
    witnesses on this matter.
    D. Other Issues
    i.     California’s Death Penalty Statute
    Caro raises a number of constitutional challenges to
    California’s death penalty scheme that we have rejected on
    87
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    multiple prior occasions. We are not persuaded to reconsider
    our precedent. (People v. Winbush, supra, 
    2 Cal.5th 402
    , 488.)
    We find no basis to conclude the state’s death penalty scheme
    violates the federal Constitution by failing to: adequately
    narrow the class of offenders eligible for the death penalty (see,
    e.g., id. at p. 488); require written findings from the jury during
    the penalty phase (see, e.g., id. at p. 490); impose a standard of
    “beyond a reasonable doubt” on jury findings in the penalty
    phase (see, e.g., id. at p. 489; People v. Case (2018) 
    5 Cal.5th 1
    ,
    50); instruct the jury on any burden of proof in the penalty phase
    (see, e.g., Winbush, at p. 489); adequately narrow the
    aggravating circumstances the jury can consider (see, e.g., ibid.);
    require jurors to find aggravating factors unanimously (see, e.g.,
    id. at pp. 489-490); inform the jury that the mitigating factors
    need not be found unanimously (see, e.g., id. at p. 490); place the
    burden of persuasion on the prosecution (see, e.g., Williams,
    
    supra,
     58 Cal.4th at p. 294); instruct the jury on a presumption
    of life (see, e.g., People v. Moore, 
    supra,
     51 Cal.4th at pp. 415-
    416); inform the jury it could impose a life sentence even if
    aggravation outweighed mitigation (see, e.g., People v. Page
    (2008) 
    44 Cal.4th 1
    , 58); instruct the jury to impose a life
    sentence if mitigation outweighed aggravation (see, e.g., id. at
    p. 57); inform the jury not to consider the deterrent effect or cost
    of the death penalty (People v. Elliott (2012) 
    53 Cal.4th 535
    ,
    590-591); adequately narrow prosecutorial discretion as to who
    is charged with capital crimes (see, e.g., People v. Weaver (2001)
    
    26 Cal.4th 876
    , 992); or require either “intercase proportionality
    review” or “the disparate sentence review that is afforded under
    the determinate sentence law” (People v. Williams (2016) 
    1 Cal.5th 1166
    , 1205). Nor did the trial court err by instructing
    the jury using adjectives such as “extreme” and “substantial” in
    88
    PEOPLE v. CARO
    Opinion of the Court by Cuéllar, J.
    the list of mitigating factors (see, e.g., People v. Boyce (2014) 
    59 Cal.4th 672
    , 724), by instructing on inapplicable sentencing
    factors (see, e.g., ibid.), or by instructing the jury to impose
    death where “warrant[ed]” (ibid.). The standard the jury uses
    to determine the penalty is not unconstitutionally vague. (See,
    e.g., ibid.). We have also repeatedly denied claims based on
    principles of equal protection (see, e.g., Winbush, at p. 490) and
    evolving standards of decency and international norms (see, e.g.,
    ibid.).
    ii.   Cumulative Error
    Caro contends that even if the asserted errors are
    harmless individually, they require reversal when considered
    cumulatively. We assumed error on the claim that the
    prosecution should have provided its investigatory material
    about prospective jurors, as well as many of Caro’s evidentiary
    and prosecutorial misconduct challenges. But no subset of these
    potential errors, or their asserted cumulative effect, requires
    reversal.

    PEOPLE v. SOCORRO CARO
    S106274
    Concurring Opinion by Justice Liu
    Today’s opinion declines to decide whether the admission
    of statements from Detective Cheryl Wade’s interview of
    defendant Socorro Caro in the hospital on November 23, 1999,
    was unconstitutional and instead finds any error harmless.
    (Maj. opn., ante, at pp. 32–41.) Although I agree that admission
    of the statements was harmless, I see no reason to leave readers
    wondering whether a constitutional violation occurred here.
    Detective Wade conducted a three-hour interview of Caro
    in the intensive care unit (ICU) a few hours after Caro had
    undergone emergency surgery for a gunshot wound to her head.
    Throughout the interview, Caro was bedridden, isolated from
    family and friends, in continuous pain, intermittently
    unconscious, under the influence of medication, encumbered by
    tubes, monitors, and intravenous lines, and suffering from a
    major foot fracture that had not yet been treated. Encountering
    Caro in this weakened state, Detective Wade sought to establish
    rapport by acting as Caro’s caregiver and medical advocate,
    without revealing to Caro (until the end of the interview) that
    Caro was a murder suspect and that Wade was there to take
    recorded statements that could be used, and were used, against
    Caro in a capital trial.
    I would hold that statements obtained under such
    circumstances are not “voluntary” — that is, they are not “ ‘ “the
    product of a rational intellect and a free will” ’ ” — and their
    1
    PEOPLE v. CARO
    Liu, J., concurring
    admission for any purpose violates due process of law. (Mincey
    v. Arizona (1978) 
    437 U.S. 385
    , 398 (Mincey).) Moreover,
    Detective Wade gave no Miranda warning until the final
    minutes of the interview. (Miranda v. Arizona (1966) 
    384 U.S. 436
     (Miranda).) Because no reasonable person in Caro’s
    position would have felt “ ‘at liberty to terminate the
    interrogation and leave’ ” (Yarborough v. Alvarado (2004) 
    541 U.S. 652
    , 663 (Yarborough)), Caro’s statements prior to the
    warning were also inadmissible under Miranda.
    The police, responding to the murder of three children,
    understandably wanted answers.           But the law provides
    safeguards against “ ‘interrogation techniques’ ” that, “ ‘as
    applied to the unique characteristics of a particular suspect, are
    so offensive to a civilized system of justice that they must be
    condemned.’ ” (Colorado v. Connelly (1986) 
    479 U.S. 157
    , 163
    (Connelly).) The hospital interview here crossed the line, and
    we should not hesitate to say so.
    I.
    “A statement is involuntary if it is not the product of ‘ “a
    rational intellect and free will.” ’ (Mincey, 
    supra,
     437 U.S. at
    p. 398.) The test for determining whether a confession is
    voluntary is whether the defendant’s ‘will was overborne at the
    time [s]he confessed.’ ” (People v. Maury (2003) 
    30 Cal.4th 342
    ,
    404 (Maury).) We ask “ ‘ “whether the influences brought to
    bear upon the accused were ‘such as to overbear petitioner’s will
    to resist and bring about confessions not freely self-
    determined.’ ” In determining whether or not an accused’s will
    was overborne, “an examination must be made of ‘all the
    surrounding circumstances — both the characteristics of the
    accused and the details of the interrogation.’ ” ’ ” (Ibid.) It is the
    2
    PEOPLE v. CARO
    Liu, J., concurring
    state’s burden to show the voluntariness of the suspect’s
    statements by a preponderance of the evidence. (Connelly,
    
    supra,
     479 U.S. at pp. 168–169.)
    The high court’s decision in Mincey is instructive here.
    That case also involved a detective’s hospital interview of a
    murder suspect. A few hours before the interview, at the
    murder scene, the police had “found Mincey lying on the floor,
    wounded and semiconscious.” (Mincey, supra, 437 U.S. at p.
    387.) At the hospital, Mincey received emergency treatment and
    was placed in the ICU. “He had sustained a wound in his hip,
    resulting in damage to the sciatic nerve and partial paralysis of
    his right leg. Tubes were inserted into his throat to help him
    breathe, and through his nose into his stomach to keep him from
    vomiting; a catheter was inserted into his bladder. He received
    various drugs, and a device was attached to his arm so that he
    could be fed intravenously.” (Id. at p. 396.)
    Evaluating these circumstances, the high court said: “It
    is hard to imagine a situation less conducive to the exercise of ‘a
    rational intellect and a free will’ than Mincey’s. He had been
    seriously wounded just a few hours earlier, and had arrived at
    the hospital ‘depressed almost to the point of coma,’ according to
    his attending physician. Although he had received some
    treatment, his condition at the time of [Detective] Hust’s
    interrogation was still sufficiently serious that he was in the
    intensive care unit. He complained to Hust that the pain in his
    leg was ‘unbearable.’ He was evidently confused and unable to
    think clearly about either the events of that afternoon or the
    circumstances of his interrogation, since some of his written
    answers were on their face not entirely coherent. Finally, while
    Mincey was being questioned he was lying on his back on a
    hospital bed, encumbered by tubes, needles, and breathing
    3
    PEOPLE v. CARO
    Liu, J., concurring
    apparatus. He was, in short, ‘at the complete mercy’ of Detective
    Hust, unable to escape or resist the thrust of Hust’s
    interrogation.”     (Mincey, 
    supra,
     437 U.S. at pp. 398–399,
    fns. omitted; see 
    id.
     at pp. 401–402 [“Mincey was weakened by
    pain and shock, isolated from family, friends, and legal counsel,
    and barely conscious, and his will was simply overborne.”].)
    The circumstances here are similar. Detective Wade
    interviewed Caro on the afternoon of November 23, 1999, less
    than 12 hours after Caro had undergone emergency
    neurosurgery for a life-threatening gunshot wound to the head.
    At 11:31 p.m. the previous night, police officers had found Caro
    lying unresponsive on the floor of her bedroom in a pool of blood
    and vomit, with a bullet wound to her head, following a 911 call
    by her husband. Paramedics transported Caro to the hospital
    by emergency airlift. At 2:30 a.m., a neurosurgeon performed
    emergency surgery to remove bullet and bone fragments
    embedded two centimeters into Caro’s brain. The surgeon
    described the wound as “a large stellate explosion-type injury in
    the right parietal area where the scalp is literally blown apart,
    and there was no entrance or exit; it was a single large wound,
    and underneath it there was a compound depressed skull
    fracture which pushed the outer table of the bone into the brain.”
    According to the surgeon, the procedure included excision of
    “[a]pproximately four by five centimeters” of skull as well as a
    “[m]inimal amount” of brain.
    When Detective Wade arrived at Caro’s hospital room
    between 12:40 p.m. and 1:00 p.m., Caro was lying intubated in
    the hospital’s ICU with a drain in her head, a breathing tube
    down her throat, binders on her hands to prevent her from
    pulling out the drain, and multiple intravenous lines (IVs) in her
    body. She had received a codeine shot roughly 90 minutes
    4
    PEOPLE v. CARO
    Liu, J., concurring
    earlier and appeared to Detective Wade to be under the
    influence of medication.
    In addition to the head injury, Caro had suffered a
    Lisfranc fracture in one of her feet that had not been treated at
    the time of the interview. As Caro’s orthopedic surgeon
    described it, “the forepart of her foot, the part that begins at the
    top of the arch and continues out to the toes, was broken away
    from the middle part of the foot, the part that makes up the top
    of the arch.” During the interview, Detective Wade observed
    that Caro’s foot “[l]ooks pretty swollen.”
    A transcript and audio recording of the interview are part
    of the publicly accessible record in this case. (Cal. Rules of
    Court, rule 2.550(c).) At the start of the interview, medical
    personnel removed Caro’s breathing tube and suctioned out the
    back of her mouth. Caro’s distress during this procedure is
    evident from sounds of coughing, choking, and gasping on the
    audio recording of the interview. Throughout the three-hour
    interview, Caro was bedridden and required medical
    interventions. Hospital staff took an X-ray of Caro’s foot, and a
    doctor examined the foot and told her she would need additional
    surgery after her brain injury had stabilized. Nurses placed a
    potassium IV in Caro’s thumb, which caused a continual
    burning sensation; physically moved Caro in order to adjust her
    drain, causing significant pain; aided her in taking pain
    medication; administered a second codeine injection; and
    administered a blood draw. In addition to the drain in her head
    and the IVs, Caro at various points had an oxygen tube in her
    nose, an oxygenation monitor on her finger, an ice pack on her
    foot, compression stockings on her legs, and an ice pack on her
    arm to ease pain from the potassium IV.
    5
    PEOPLE v. CARO
    Liu, J., concurring
    Caro complained of severe pain continuously during the
    interview. At times, she was reduced to sobbing, moaning, or
    exclaiming, “It hurts, hurts, hurts, hurts, hurts” or “Ow, ow,
    ow.” She expressed pain from the removal of the breathing tube
    and the removal of tape from her face. Three times, she
    complained of pain in her head. Twice, she indicated her throat
    was sore. Seven times, she reported serious pain in her neck
    and shoulders. Eleven times, she complained of severe pain
    from the potassium IV. Her broken foot was swollen and sore,
    and the doctor’s physical examination of the foot caused her
    pain. At one point, Caro reported feeling pain “all over.” Her
    back hurt. Her ears hurt. Her hands hurt. Her right arm and
    the inside of her thighs were bruised. She complained of
    discomfort from the oxygenation monitor on her finger, the
    compression stockings on her legs, the patches on her skin for
    monitoring vital signs, and the oxygen tube in her nose, which
    she tried to remove at least three times. In all, Caro expressed
    pain through words or moans at least 55 times during the
    interview.
    Moreover, Caro drifted in and out of consciousness,
    especially after she received the second codeine injection. At
    times, her pain and fatigue reduced her to nonverbal
    communication. At one point, she told Detective Wade, “I’m
    doing my best so I can go to bed.” A few minutes later, Caro
    appeared to fall asleep, prompting Detective Wade to ask, “Are
    you awake? Socorro? So we can talk to you? Are you awake so
    I can talk to you?” In her debilitated condition, Caro repeatedly
    expressed confusion and inability to recall what happened the
    previous night or why she was injured. In the middle of the
    interview, she could not remember Detective Wade’s name. She
    exhibited no awareness that her children had been killed,
    6
    PEOPLE v. CARO
    Liu, J., concurring
    instead telling Detective Wade at one point that she believed
    they were at home with their grandmother. (At the penalty
    phase, a neuropsychologist gave unrebutted testimony that
    Caro suffered from continued amnesia about the events of that
    evening seven months later due to the combination of her brain
    injury and the alcohol and medication in her system when the
    events occurred.)
    Thus, Caro was interrogated when she was “seriously . . .
    wounded” (Mincey, supra, 437 U.S. at p. 401), “weakened by
    pain” (ibid.), “on the edge of consciousness” (ibid.), and
    “evidently confused and unable to think clearly about either the
    events of [the previous night] or the circumstances of [her]
    interrogation” (id. at p. 398). Caro was also “isolated from
    family, friends, and legal counsel” throughout the interview.
    (Id. at p. 401.) In Mincey, the high court concluded that in light
    of Mincey’s “debilitated and helpless condition” (id. at p. 399),
    “his will was simply overborne” (id. at pp. 401–402) by the
    detective’s “virtually continuous questioning” for four hours
    despite Mincey’s several requests to be let alone (id. at p. 401).
    Here, Detective Wade subjected Caro to repetitive and “virtually
    continuous questioning” for three hours (ibid.), and although the
    interrogation did not proceed in the face of a direct request to
    stop, an unmistakable element of “improper influence” is
    evident in the interaction. (Maury, supra, 30 Cal.4th at p. 404
    [“A confession may be found involuntary if . . . secured by the
    exertion of improper influence.”].)
    Interrogation   tactics  that    exploit    a   suspect’s
    vulnerabilities may render statements involuntary. “[A]s
    interrogators have turned to more subtle forms of psychological
    persuasion, courts have found the mental condition of the
    defendant a more significant factor in the ‘voluntariness’
    7
    PEOPLE v. CARO
    Liu, J., concurring
    calculus.” (Connelly, 
    supra,
     479 U.S. at p. 164.) One form of
    psychological pressure is a “false friend” technique in which the
    officer misleads the suspect into believing the officer is
    protecting her best interests. (State v. Rettenberger (Utah 1999)
    
    984 P.2d 1009
    , 1016–1017.) Another is manipulation through
    misrepresentation of fundamental aspects of the interrogation.
    (State v. Eskew (Mont. 2017) 
    390 P.3d 129
    , 135–136.)
    Throughout the interview here, Detective Wade presented
    herself to Caro as a supportive caregiver and advocate for Caro’s
    medical needs and recovery. From the beginning, Detective
    Wade addressed Caro with terms of endearment (“Honey,”
    “Hon”) and spoke words of support and encouragement as Caro
    struggled with her physical condition (e.g., “You’re doing great”
    “Just relax” “Feels good to take a breath, huh?” “You’re doing
    terrific” “I know it hurts but you’re doing great” “Everything’s
    looking great”). In multiple interactions, Detective Wade
    assumed a caregiving role and projected a unity of interest with
    Caro. She reminded Caro not to pull out the drain in her head
    (“I know you know. . . . [I]t just makes me feel better to remind
    you.”). She adjusted Caro’s pillow and helped her roll over in
    the bed (“There you go. . . . Is that better?”). She repeatedly fed
    Caro ice chips (“Here you go, Hon. Open up. How’s that? Is
    that better?”). She placed an ice pack on Caro’s arm. She called
    a nurse to obtain medication when Caro requested it. She
    helped untangle Caro’s medical wires. She even adjusted Caro’s
    robe for her. And she repeatedly urged Caro to rely on her for
    any needs (“If you need anything just let me know, okay?” “You
    need something?” “Is that pillow bothering you?” “You want . . .
    another ice chip?” “Can I get you anything else?” “Do you need
    anything else?” “I’ll just help you out, okay?” “Well, I know
    8
    PEOPLE v. CARO
    Liu, J., concurring
    you’re not alright. I’m sorry to say that but if there’s anything I
    can get you, you let me know, okay?”).
    At no point did Detective Wade give Caro privacy in
    medical treatment or in discussion with medical personnel
    about her condition. To the contrary, Detective Wade interposed
    herself between Caro and the hospital staff. She communicated
    with the medical team on Caro’s behalf, alerting them to pain in
    Caro’s shoulders and conveying Caro’s answers to questions
    posed by the orthopedist. At various points, Detective Wade
    projected a measure of control over Caro’s medical care.
    Hospital staff even conferred with Detective Wade before
    providing Caro with a codeine shot: A nurse told Detective
    Wade that she (the nurse) recognized Caro was “hurting and
    uncomfortable” and “would like to give her something for the
    pain,” “but I don’t want to mess up your thing.” Wade eventually
    responded, “All right. If that’s what you would normally do,
    then go ahead.” The nurse noted that Caro was “just constantly”
    saying that “everywhere hurts” and that she (the nurse) had
    “been trying to put it off.” After some discussion, Detective
    Wade said, “Right. Right. So go ahead.”
    On the surface, much of Detective Wade’s interaction with
    Caro resembled the type of encouragement and comfort that a
    family member or friend would ordinarily provide to a fragile
    patient. In fact, however, Caro was isolated from her family and
    friends, and Detective Wade was not there to be Caro’s friend.
    She was there to obtain recorded statements from a murder
    suspect and to elicit potentially incriminating information that
    could be used, and was used, to try the suspect for capital
    crimes. Notwithstanding her apparent solicitude for Caro’s
    well-being, Detective Wade’s interests were plainly adverse to
    Caro’s.
    9
    PEOPLE v. CARO
    Liu, J., concurring
    Moreover, Detective Wade deliberately kept Caro in the
    dark about the fundamental context of the interrogation, i.e.,
    that Caro’s children were dead and Caro was a suspect. Only at
    the end — after hours of seemingly supportive and ingratiating
    talk — did Detective Wade reveal to Caro: “[R]ight now I’m
    conducting . . . an investigation into the death of your boys . . . .”
    and “Now, you’re suspected of hurting your boys.” Detective
    Wade then gave Miranda warnings, and Caro invoked her right
    to counsel. Upon grasping that her boys were dead, Caro let out
    a series of audible gasps and cries over the course of several
    minutes in a chilling denouement to the interrogation.
    In sum, it does not take much for a police interrogation to
    overbear the will of a person in an intensive care unit who, as a
    result of a gunshot wound to the head and emergency
    neurosurgery, is experiencing severe pain and intermittently
    losing consciousness. By acting as Caro’s caregiver and
    advocate while withholding the fundamental context of the
    interrogation, Detective Wade exerted improper influence over
    a gravely injured and weakened suspect. Caro did not directly
    ask to stop the interview (until the end), but she repeatedly said
    she was in pain and wanted to sleep. While allowing Caro to
    sleep at various points, Detective Wade “ceased the
    interrogation only during intervals when [Caro] lost
    consciousness or received medical treatment, and after each
    such interruption returned relentlessly to [her] task.” (Mincey,
    supra, 437 U.S. at p. 401.) It is not plausible to describe
    submission to such interrogation by anyone in Caro’s condition
    as “voluntary” in any meaningful sense of the word. (See
    Connelly, 
    supra,
     479 U.S. at p. 163 [voluntariness inquiry must
    examine “ ‘interrogation techniques . . . as applied to the unique
    characteristics of a particular suspect’ ”]; Miller v. Fenton (1985)
    10
    PEOPLE v. CARO
    Liu, J., concurring
    
    474 U.S. 104
    , 116 [voluntariness inquiry must examine
    “techniques for extracting the statements, as applied to this
    suspect”].) Although the trial court opined that Detective Wade
    did not do “anything to overcome” Caro’s will, the voluntariness
    of a suspect’s statement, “to the extent the interview is tape-
    recorded,” is “subject to our independent review.” (People v.
    Linton (2013) 
    56 Cal.4th 1146
    , 1177.) I would hold that
    admission of Caro’s statements for any purpose offends due
    process of law.
    II.
    Caro’s statements were also inadmissible during the
    prosecution’s case-in-chief for a separate reason: They were
    obtained before Detective Wade informed Caro of her Miranda
    rights. (See Missouri v. Seibert (2004) 
    542 U.S. 600
    , 608
    [“Miranda conditioned the admissibility at trial of any custodial
    confession on warning a suspect of h[er] rights: failure to give
    the prescribed warnings and obtain a waiver of rights before
    custodial questioning generally requires exclusion of any
    statements obtained.”].)
    To determine whether an individual is in custody for
    Miranda purposes, we ask “ ‘first, what were the circumstances
    surrounding the interrogation; and second, given those
    circumstances, would a reasonable person have felt he or she
    was not at liberty to terminate the interrogation and leave.’ ”
    (Yarborough, supra, 541 U.S. at p. 663; see Miranda, 
    supra,
     384
    U.S. at p. 444 [“By custodial interrogation, we mean questioning
    initiated by law enforcement after a person has been taken into
    custody or otherwise deprived of his freedom of action in any
    significant way.”].) When urging the admissibility of statements
    obtained through police questioning without Miranda warnings,
    11
    PEOPLE v. CARO
    Liu, J., concurring
    it is the state’s burden to establish that the suspect was not in
    custody. (See People v. Davis (1967) 
    66 Cal.2d 175
    , 180–181.)
    In this case, several factors would have caused a
    reasonable person in Caro’s position to believe that law
    enforcement was in control of the interaction and that she was
    not free to terminate the interrogation and leave. The
    interrogation occurred in a hospital ICU; Detective Wade’s
    assertive presence in an intimate environment where visitation
    is typically reserved for family and friends is itself significant.
    There is no evidence that she or other members of the Ventura
    County Sheriff’s Department ever asked for Caro’s permission
    to be present. And as noted, Detective Wade did not step out or
    step aside, or offer to do so, when Caro was undergoing medical
    treatment or having conversations with hospital staff about her
    bodily condition and medical needs. Even the hospital staff
    seemed to regard Detective Wade as having a measure of control
    over Caro’s medical care, as indicated by the conversation in
    which a nurse told Detective Wade that she (the nurse) wanted
    to give Caro a codeine shot “but I don’t want to mess up your
    thing.”
    In addition to Detective Wade, other law enforcement
    personnel were present. Detective Jose Rivera of the sheriff’s
    department had been stationed by Caro’s bedside or outside her
    room from the time Caro emerged from surgery, and he stayed
    there throughout the interrogation. A deputy district attorney
    also stood outside the glass door to Caro’s room. At one point,
    Caro asked about him, and Wade responded, “He’s with the DA’s
    office.” A psychologist hired by the district attorney’s office, Dr.
    Susan Ashley, was present as well.
    12
    PEOPLE v. CARO
    Liu, J., concurring
    Further, Caro was “isolated from family, friends, and legal
    counsel.” (Mincey, 
    supra,
     437 U.S. at p. 401.) From the time she
    regained consciousness after neurosurgery, Caro’s only
    interactions (besides speaking to Detective Wade and briefly to
    Detective Rivera) were with medical personnel, and even in
    those interactions, Detective Wade several times interposed
    herself as Caro’s caregiver or advocate. (See Miranda, 
    supra,
    384 U.S. at p. 445 [“incommunicado interrogation of individuals
    in a police-dominated atmosphere” carries substantial risk of
    Fifth Amendment violation “without full warnings of
    constitutional rights”].)
    The circumstances of the interview were entirely
    consistent with the nature of Detective Wade’s assignment that
    day: Caro was suspected of murdering her children, and
    Detective Wade was at the hospital to find out from Caro what
    had happened. It is hard to imagine that law enforcement
    officers, less than 24 hours after a triple murder, would have
    allowed a key suspect to leave their presence, and the whole
    context of the interaction would have made clear to a reasonable
    person in Caro’s position that she was not “ ‘at liberty to
    terminate the interrogation and leave.’ ” (Yarborough, supra,
    541 U.S. at p. 663; cf. U.S. v. Martin (9th Cir. 1985) 
    781 F.2d 671
    , 673 [“If the police took a criminal suspect to the hospital
    from the scene of a crime, monitored the patient’s stay, stationed
    themselves outside the door, arranged an extended treatment
    schedule with the doctors, or some combination of these, law
    enforcement restraint amounting to custody could result.”].)
    The only reason for delaying the Miranda warning appears to
    have been Detective Wade’s determination to elicit statements
    from Caro before revealing to her that her children had died and
    that she was suspected of harming them.
    13
    PEOPLE v. CARO
    Liu, J., concurring
    The control exercised here by law enforcement in its
    interaction with a bedridden, isolated, and severely injured
    suspect underscores the involuntariness of any statements
    obtained. Simple, lawful alternatives were available. Caro was
    not going anywhere, and the police had appropriately
    sequestered her in the ICU. Detective Wade could have waited
    to interview her until her condition had stabilized and she was
    fully awake, alert, and not in serious pain. Further, Detective
    Wade could have provided Caro with Miranda warnings at the
    outset of an interview, as the law requires. The state has not
    advanced any argument based solely on the fact that a murder
    had been committed, nor could it. Just as there is no “ ‘murder
    scene exception’ ” to the Fourth Amendment — that is, a
    warrantless search “[i]s not constitutionally permissible simply
    because a homicide ha[s] recently occurred” — there is no
    homicide exception to the Fifth Amendment or to the guarantee
    of due process of law. (See Mincey, 
    supra,
     437 U.S. at p. 395.)
    Caro’s statements were inadmissible, and I would so hold.
    In all other respects, I join today’s opinion.
