    SECOND APPELLATE DISTRICT
    DIVISION SIX
    THE PEOPLE,                                                                  2d Crim. No. B250071

    Plaintiff and Respondent,                                            (Los Angeles County)
    v.
    MARK EDWARD VAUGHN,
    Defendant and Appellant.
    Mark Edward Vaughn appeals his conviction, by jury, of the second
    degree murder (Pen. Code, §§ 187, subd. (a), §189) of 17-month-old Jayden T., and
    of assault on a child causing death (§ 273ab, subd. (a)). The trial court sentenced
    appellant to a term of 25 years to life in state prison on the assault conviction and
    stayed the term imposed for murder pursuant to section 654.1
    Appellant contends the judgment is not supported by substantial
    evidence because there is no evidence he assaulted Jayden or otherwise caused her
    injuries. He further contends the trial court erred because it failed to instruct the
    jury that a homicide committed by accident is excusable and because it failed to
    instruct the jury on the lesser included offense of involuntary manslaughter.
    1
    All statutory references are to the Penal Code.
    Finally, appellant contends he received ineffective assistance of counsel at trial
    because counsel failed to impeach the victim's mother and grandmother with their
    prior inconsistent statements, because counsel did not call any expert witnesses, and
    did not interview or call a percipient witness to his demeanor after Jayden was
    injured. We affirm.
    FACTS
    Appellant was the fiancé of Jayden's mother, Koryne. He is not
    Jayden's biological father. Koryne, then a nursing student, lived with her mother,
    Lisa, in Lisa's La Mirada home. On January 20, 2012, Koryne had an early class
    and Lisa had to work. Jayden's regular babysitters were not available, so appellant
    agreed to watch her until Koryne returned from class. He arrived at about 11:30
    p.m. on the night before and stayed the night with Koryne.
    On the morning of January 20, Koryne left the house at about 6:00
    a.m. Lisa got up at about 6:30 a.m. She got ready for work and then woke Jayden.
    Lisa got Jayden ready for the day and fed her breakfast. By 8:15 a.m., appellant
    was awake and sitting on the couch with a lap top computer. He took Jayden from
    Lisa and Lisa left for work. Lisa testified that Jayden was clingy and crying when
    she left for work.
    At about 10:20 a.m., appellant called 911, reporting that Jayden had
    fallen off a chair and was not breathing. Los Angeles County Sheriff's Deputy
    Patrick Unkle happened to be driving to his assignment at a nearby high school
    when he heard the dispatch. He arrived at the house about one minute later. Jayden
    was unresponsive, lying on her back, on the carpeted living room floor near a coffee
    table. Deputy Unkle asked appellant what happened. Appellant said the baby fell
    from the chair. When Deputy Unkle asked whether she hit her head on the table,
    appellant said he did not think so because it sounded like she hit the carpet. Jayden
    was not breathing. Deputy Unkle asked whether appellant had started CPR. He
    said "No," and that he was still talking to the 911 dispatcher. The deputy started
    CPR. He asked appellant to give Jayden breaths, while he gave her chest
    2
    compressions. Appellant gave two rescue breaths and then stood up and walked
    into the kitchen. He did not re-engage with Jayden while Deputy Unkle was
    present. Deputy Unkle continued to give Jayden CPR until paramedics arrived a
    few minutes later. He described appellant's demeanor during this period as
    "Extremely calm."
    When the paramedics arrived at about 10:25 a.m., Jayden was in
    cardiac arrest and "ghost white." She was wearing only a diaper and felt cold to the
    touch. Her pupils were fixed and dilated. Paramedic Joel Entreken testified that he
    observed bruising behind both of Jayden's ears, which is indicative of a skull
    fracture. When he touched her head, he noticed "crepitus," or the "sensation of
    fracture bones grinding together." Appellant told the paramedic that Jayden fell off
    of the chair onto the carpeted floor and hit her head. He also said Jayden vomited
    while he was on the phone with 911. The paramedic described appellant's
    demeanor as "pretty emotionless . . . like he was just kind of a bystander." Another
    paramedic described the crepitus he observed on Jayden's head as the worst he had
    ever felt on a person.
    Michael Mileki, a sergeant from the Los Angeles County Sheriff's
    Department, interviewed appellant at the house after Jayden was taken to the
    hospital. Appellant told Sgt. Mileki that he placed Jayden on a loveseat in the
    living room, turned on the TV so she could watch cartoons, and went into the
    kitchen to make breakfast for himself. While in the kitchen, he heard a "loud thud"
    and the sound of Jayden crying. It sounded to him as if Jayden had fallen off the
    couch. He immediately went to her. She was on her back with one foot propped up
    on the loveseat. Appellant said that he picked Jayden up and held her for about 30
    minutes while she cried. Eventually, she started to become sleepy. He tried to keep
    her awake because he was not sure whether she had a concussion. She tried to close
    her eyes for about 15 minutes and then became unresponsive. At that point,
    appellant called 911. He did not start CPR because he thought she was still
    breathing. He put her on the floor and waited for the fire department to arrive.
    3
    Appellant seemed indifferent during the interview and seemed to feel "no sense of
    urgency" about the situation.
    Jayden's aunt arrived at the house and confronted appellant about
    what had happened. He told the aunt that he was in the kitchen when he heard a
    "thump or like a thud." He went into the living room and found Jayden on her back
    with her leg propped up on the chair. She was crying and he picked her up to
    console her. She eventually calmed down, but then she became woozy and he
    called 911.
    Detectives from the Sheriff's department inspected the area where
    appellant said Jayden fell. They found that Lisa's living room floor was constructed
    of a plywood subfloor over a concrete slab. The plywood was covered with
    padding and carpeting. Detectives found no blood, skin, or hair on either the coffee
    table or the floor. They returned to search the house on five occasions. Trace
    evidence of DNA was found on a piece of drywall they removed from a bathroom
    wall directly behind Jayden's potty chair. Aside from Jayden's injuries, there were
    no signs that a struggle had occurred in the house and the detectives found "no
    evidence of anything that was used a weapon."
    On the day of the incident, Koryne asked appellant what happened.
    He told Koryne "that he had set the baby in a chair in our living room and went into
    the kitchen to make food, and he said he heard a thud and went into the living room
    and found the baby on her back with her foot up on the chair still." Jayden was
    crying so appellant picked her up and consoled her. They started playing. About
    30 to 45 minutes later, Jayden started moaning and losing consciousness. Two
    weeks later, in early February 2012, Koryne asked appellant whether he put ice on
    Jayden's head. He told her that he did. She said, "'You didn't tell me that. Why
    didn't you tell me that?'" Appellant replied, "'I only told you 90 percent of what
    happened.'" Although Koryne asked appellant to tell her the other 10 percent, he
    refused.
    4
    Dr. Lawrence Nguyen, the medical examiner who performed the
    autopsy on Jayden, testified that he observed extensive hemorrhaging within her
    scalp and "severe complex skull fractures." There was a horizontal fracture that
    extended from the top of the skull all the way to the base of the skull. Other
    horizontal fracture lines emanated from that fracture. These fractures were caused
    by an external impact, rather than from internal pressure caused by brain swelling.
    Dr. Nguyen opined that Jayden must have suffered at least two strikes to her head.
    Jayden also had bruising around her occipital scalp. Dr. Nguyen
    would not expect to see that bruising after a fall from 20 inches onto a carpeted,
    padded wooden floor. He would, instead, expect to see that level of bruising after a
    fall from a height of 10 feet or more. Dr. Nguyen observed a round bruise on
    Jayden's cheek that could have come from a hand or a thumb. In addition, the
    medical examiner observed an area of hemorrhage on her neck and trauma below
    her thyroid. These injuries are typically caused by a blow or by clutching of the
    neck.
    Dr. Carol Berkowitz, an expert in pediatric emergency medicine and
    child abuse pediatrics, and the co-chair of the Child Death Review for Los Angeles
    County, reviewed the photographs and report of Jayden's autopsy. She opined that
    Jayden's injuries were not consistent with a fall from a chair onto a carpeted,
    padded, wood surface. Instead, her injuries were caused by an "inflicted severe
    blow to her head." It was not possible for her to say, to a medical certainty, how
    many blows were inflicted. However, Dr. Berkowitz believed the blows were
    inflicted by an object, rather than by a hand or a foot. A man of appellant's height
    and weight would be able to inflict these injuries "if he hit the child against a hard
    object like the wall or some other thing, but I believe it would have had to be
    contact with something hard, either something hard hitting the head or the head
    hitting something hard." Such a blow would not necessarily damage the wall or
    leave blood, hair or skin behind.
    5
    The fracture to Jayden's skull was so severe that it crossed the suture
    line, or the line that separates the different bones in the skull. A fall from a chair
    onto a carpeted surface could not generate sufficient velocity to cause that facture.
    To create an injury as severe as Jayden's, a child would have to fall "from probably
    two stories, or more than that . . . out of a window onto a concrete surface where the
    fall wasn't broken by any intervening items such as a tree or bushes, or it would
    occur with an ejection from a car where the child was thrown out of the car and,
    again, hit concrete."
    Dr. Berkowitz did not believe Jayden would have cried after she
    received these injuries, as appellant described. She would, instead, have been
    immediately symptomatic because the injury was so massive.
    Both experts acknowledged on cross-examination the existence of at
    least one other expert who found "that a fall of less than . . . three meters by a child
    can cause these kinds of complex injuries[.]" Doctors Nguyen and Berkowitz noted
    their disagreement with that expert. In addition, Dr. Berkowitz described a study of
    "death related to short falls in children, and short falls were one and a half
    meters[.]" The study concluded, "your chance of dying as a result of a short fall . . .
    was .48 in one million." The defense called no expert witnesses to rebut the
    testimony of Doctors Nguyen and Berkowitz.
    Jayden's mother, Koryne, and grandmother, Lisa, described some
    minor injuries Jayden had sustained in the months prior to her death. One or two
    months before her death, Jayden hit the back of her head on the bathtub. She cried
    for a couple of minutes and had a bump on her head, but did not lose consciousness.
    Jayden also fell while running on a neighbor's driveway. She hit her nose and her
    hands but had no severe injuries. Finally, Jayden hit her head on a bed rail while
    she was staying at appellant's house several months before her death. Appellant
    explained to Lisa that Jayden was on the bed when he saw her start to roll off. He
    stuck his hand out, to catch her and, in doing so, shoved her into the bed rail.
    6
    Jayden hit her head, causing some bumps and bruises on her face. Koryne and Lisa
    took her to the doctor.
    In his trial testimony, appellant said he loved Jayden. He denied
    hitting or bashing her head into a wall. Appellant testified that he put an ice pack
    on Jayden's head after her fall. She continued to cry. He took off her pajamas when
    it seemed like she was having trouble breathing. He tried to keep her awake
    because he thought she might have a concussion. Appellant did not tell the
    detectives about the ice pack because they did not ask him about it.
    Appellant testified that he was Jayden's disciplinarian and "chief potty
    trainer." He corrected her by "saying 'no' or just talking to her[.]" On one occasion,
    appellant left Jayden on her potty for an hour because, he told detectives, "'I wanted
    her to go potty.'" After she did, they shared a big bowl of ice cream.
    Appellant's father described him as being "soft spoken," with a "soft
    demeanor." Appellant had, his father believed, a "very loving relationship" with
    Jayden. One of appellant's friends described appellant as having "almost like a
    father-daughter relationship" with Jayden. The friend had never seen appellant
    involved in a physical fight and described him as not a violent person.
    PROCEDURAL HISTORY
    The jury found appellant guilty of murder (§ 187, subd. (a)) and
    assault on a child causing death (§ 273ab, subd. (a)). Appellant retained new
    counsel, obtained a 30-day continuance and filed a motion for new trial. Among
    other things, appellant contended in the motion for new trial that his defense
    counsel at trial was ineffective because counsel failed to call any expert witnesses in
    neurology, pathology or psychology. In support of the motion, appellant submitted
    the declarations of Dr. Charles Niesen, a pediatric neurologist, and Dr. Janice
    Ophoven, a pediatric pathologist. Dr. Niesen opined that Jayden's injuries could
    have been sustained in an accidental fall, especially if her head hit a hard surface
    like the wooden table that was present in Lisa's living room at the time. Dr.
    Ophoven opined that Jayden might have been conscious for a significant period of
    7
    time after sustaining the head injury and that the skull fracture could have been
    produced by even a short fall. Appellant also submitted the declaration of a
    forensic psychologist who opined that appellant "does not present with the
    characteristics associated with a proneness for violence; against children or adults."
    The trial court denied the motion for new trial. It summarized the
    expert medical testimony indicating that Jayden suffered several traumatic injuries
    to the skull that could not have been caused by falling from a chair onto a carpeted
    floor. The trial court also mentioned appellant's testimony that he put ice on
    Jayden's head and noted, "no evidence of an ice pack was ever found either in the
    refrigerator or freezer . . . or in the vicinity of where the child was found when the
    911 responders arrived." Referring to the autopsy photographs of Jayden's skull,
    the court stated: "I remember vividly the exhibits of the peeled-back skin, and the
    skull, and the fractures. It is so highly unlikely that a slight or small distance of 20
    to 30 inches . . . the injuries were severe and could not have occurred as [appellant]
    has indicated, and the two experts who belatedly have submitted their declarations,
    it can be argued -- I've read the declarations-- it can be argued that counsel could
    have or should have called one or both or other experts, but the fact is counsel
    didn't, and I do not know because I have no evidence to that effect who it is, if any,
    experts were contacted by original counsel or the defendant and he intelligently and
    reasonably -- based on the standards that attorneys must exercise -- decided that it
    would not have been in his client's best interests to having done so. [¶] There is
    absolutely no basis in the court's opinion to grant the motion, and I'm going to
    proceed with the sentence."
    DISCUSSION
    Substantial Evidence
    Appellant contends the judgment is not supported by substantial
    evidence because there is no evidence he caused Jayden's injuries. The contention
    is without merit.
    8
    "'"In assessing a claim of insufficiency of evidence, the reviewing
    court's task is to review the whole record in the light most favorable to the judgment
    to determine whether it discloses substantial evidence . . . that is reasonable,
    credible, and of solid value—such that a reasonable trier of fact could find the
    defendant guilty beyond a reasonable doubt. . . . The standard of review is the same
    in cases in which the prosecution relies mainly on circumstantial evidence. . . .
    "'Although it is the duty of the jury to acquit a defendant if it finds that
    circumstantial evidence is susceptible of two interpretations, one of which suggests
    guilt and the other innocence . . ., it is the jury, not the appellate court[,] which must
    be convinced of the defendant's guilt beyond a reasonable doubt. '"If the
    circumstances reasonably justify the trier of fact's findings, the opinion of the
    reviewing court that the circumstances might also reasonably be reconciled with a
    contrary finding does not warrant a reversal of the judgment. . . ."' [Citation.]"
    (People v. Tully (2012) 
    54 Cal. 4th 952
    , 1006-1007.)
    The jury found that appellant committed murder (§ 187) and assault
    on a child causing death (§ 273ab). Murder is the unlawful killing of a human
    being with express or implied malice aforethought. Malice is express when the
    defendant manifests a deliberate intention unlawfully to kill a human being. It is
    implied when the killing results from an intentional act the natural consequences of
    which are dangerous to human life and the act was deliberately performed with
    knowledge of the danger to, and conscious disregard for, human life. (§§ 187, 188;
    People v. Cook (2006) 
    39 Cal. 4th 566
    , 596.) A violation of section 273ab requires
    proof that the defendant had the care or custody of a child under eight years of age,
    the defendant committed an assault on the child, the assault was committed by
    means of force that to a reasonable person would be likely to produce great bodily
    injury, and the assault resulted in the death of the child. (People v. Malfavon (2002)
    
    102 Cal. App. 4th 727
    , 735.)
    The record here contains substantial evidence that appellant
    committed both offenses. Appellant was alone with Jayden when she was injured.
    9
    Two medical experts testified that the severe complex skull fractures she sustained
    could not have been inflicted by the type of accidental fall appellant described.
    Instead, both expert witnesses opined the injuries were consistent with a very severe
    blow to the head inflicted by a hard object, such as by bashing Jayden's head into a
    wall. An injury this severe could not have been sustained in an accidental fall
    unless the fall was from a multi-story building onto a concrete surface.
    Additionally, Jayden sustained trauma below her thyroid, an injury that typically
    results from clutching the neck. The jury could have reasonably inferred, based on
    all of this evidence, that Jayden's injuries were caused by appellant's intentional
    conduct. It could further have reasonably inferred that appellant acted with express
    or implied malice when he hit the victim's head against a wall or other hard object
    with sufficient force to cause those severe skull fractures. Thus, there was
    substantial evidence to support both verdicts.
    Instructional Error
    Appellant contends the trial court prejudicially erred when it failed to
    instruct the jury that a homicide is excusable if it is committed by accident or
    misfortune and when it failed to instruct the jury on involuntary manslaughter as a
    lesser included offense of murder. We are not persuaded.
    The trial court has a duty to instruct, sua sponte, on general principles
    of law that are commonly or closely and openly connected to the facts before the
    court and that are necessary for the jury's understanding of the case. (People v.
    Boyer (2006) 
    38 Cal. 4th 412
    , 468-469.) This duty extends to defenses "'"only if it
    appears that the defendant is relying on such a defense, or if there is substantial
    evidence supportive of such a defense and the defense is not inconsistent with the
    defendant's theory of the case."' [Citation.]" (People v. Maury (2003) 
    30 Cal. 4th 342
    , 424.) In this context, evidence is "'substantial' only if a reasonably jury could
    find it persuasive. [Citation.]" (People v. Young (2005) 
    34 Cal. 4th 1149
    , 1200.)
    The trial court's duty to instruct "'. . . has been held to include giving
    instructions on lesser included offenses when the evidence raises a question as to
    10
    whether all of the elements of the charged offense were present . . . but not when
    there is no evidence that the offense was less than that charged. [Citations.]' . . ."
    (People v. Breverman (1998) 
    19 Cal. 4th 142
    , 154.) The trial court must instruct on
    all theories of the lesser included offense which find substantial support in the
    evidence, e.g., "'"evidence from which a jury composed of reasonable [persons]
    could . . . conclude[]"' that the lesser offense, but not the greater, was committed.
    [Citations.]" (Id. at p. 162.)
    Homicide by Accident or Misfortune
    Appellant contends the trial court erred when it failed to instruct the
    jury, "When a person commits an act or makes an omission through misfortune or
    by accident under circumstances that show [neither criminal intent nor purpose nor
    criminal negligence] he does not thereby commit a crime." (CALJIC No. 4.45.) In
    addition, appellant contends, the trial court should have instructed the jury that,
    "The unintentional killing of a human being is excusable and not unlawful when
    (1) committed by accident and misfortune in the performance of a lawful act by
    lawful means and (2) where the person causing the death acted with that care and
    caution which would be exercised by an ordinarily careful and prudent individual
    under like circumstances." (CALJIC No. 5.00.)
    The trial court declined to instruct the jury with either of these pattern
    instructions on the ground that there was no substantial evidence to support them.
    Appellant contends the jury might have found he acted negligently when he left
    Jayden unattended and that she died after accidentally falling from the living room
    chair. In addition, appellant contends, the jury might have found that Jayden's
    earlier accidental head injuries (e.g., from falling in the driveway or hitting her head
    in the bathtub) contributed to the severity of the injury she sustained in the
    accidental fall, causing her death.
    This argument is without merit. As the trial court correctly
    concluded, there was no substantial evidence supporting the theory that Jayden died
    as the result of an accident that occurred while appellant was performing a lawful
    11
    act with reasonable care, as required by CALJIC No. 5.00. The expert medical
    testimony was that Jayden's injuries were so extensive, they could not have been
    caused by an accidental fall from a living room chair. The same experts further
    testified there was no evidence of any "previous healing fracture[s]" on Jayden's
    skull. As a consequence, the evidence that Jayden may have hit her head in the
    bathtub or fell on a neighbor's driveway in the months or weeks prior to her death
    was not sufficient to warrant jury instructions on accidental death. Nor did
    appellant's testimony provide substantial evidentiary support for the accident
    instructions. Appellant claims that he placed the 17-month-old Jayden in a chair
    and then left her unattended for several minutes. There is no substantial evidence
    that this conduct was consistent with the "care and caution which would be
    exercised by an ordinarily careful and prudent individual under like circumstances."
    (CALJIC No. 5.00.)
    Involuntary Manslaughter as a Lesser Included Offense
    Appellant contends the trial court erred when it refused to instruct the
    jury on involuntary manslaughter as a lesser included offense of murder. He argues
    the jury could have found Jayden's skull fractures were caused by a misdemeanor
    battery or some form of criminally negligent conduct. We are not persuaded.
    Involuntary manslaughter is a lesser related offense of assault on a
    child resulting in death, rather than a lesser included offense. (Orlina v. Superior
    Court (1999) 
    73 Cal. App. 4th 258
    , 262.) "[A] defendant has no right to instructions
    on lesser-related offenses even if he requests the instruction and it would have been
    supported by substantial evidence. [Citation.]" (People v. Valentine (2006) 
    143 Cal. App. 4th 1383
    , 1387.) Consequently, the trial court had no duty, sua sponte or
    otherwise, to instruct on involuntary manslaughter as an alternative to the assault
    charged here. (People v. Stewart (2000) 
    77 Cal. App. 4th 785
    , 786.)
    Involuntary manslaughter is, however, a lesser included offense of
    murder. (People v. Abilez (2007) 
    41 Cal. 4th 472
    , 515.) "One commits involuntary
    manslaughter either by committing 'an unlawful act, not amounting to a felony' or
    12
    by committing 'a lawful act which might produce death, in an unlawful manner, or
    without due caution and circumspection.' [Citation.] If the evidence presents a
    material issue of whether a killing was committed without malice, and if there is
    substantial evidence the defendant committed involuntary manslaughter, failing to
    instruct on involuntary manslaughter would violate the defendant's constitutional
    right to have the jury determine every material issue. [Citation.]" (People v. 
    Cook, supra
    , 39 Cal.4th at p. 596.)
    There was no substantial evidence that Jayden's multiple, complex
    skull fractures were caused when appellant committed a misdemeanor battery, or
    when he committed some other "lawful act which might produce death" in a
    criminally negligent manner. (§ 192, subd. (b).) Instead, the expert medical
    testimony was that Jayden's skull fractured when her head was forcefully hit by, or
    slammed into a hard object such as a floor or a wall. Appellant's testimony was that
    no battery occurred at all. Neither scenario supports an instruction on involuntary
    manslaughter.
    Harmless Error
    Any error in the trial court's failure to instruct the jury on accident or
    on involuntary manslaughter was harmless because there is no reasonable
    probability appellant would have achieved a more favorable result had the
    instructions been given. (People v. 
    Breverman, supra
    , 19 Cal.4th at p. 178; People
    v. Russell (2006) 
    144 Cal. App. 4th 1415
    , 1431-1432.) When the jury found
    appellant guilty of violating section 273ab, it expressly found that appellant
    willfully assaulted Jayden "by means of force that to a reasonable person would be
    likely to produce great bodily injury," and that the assault resulted in her death.
    (§ 273ab, subd. (a); CALJIC No. 9.36.5.) The finding that appellant acted
    intentionally is inconsistent with the defense that Jayden's death was the result of an
    accident. (People v. Jones (1991) 
    234 Cal. App. 3d 1303
    , 1314-1316.) Any error in
    the failure to instruct on involuntary manslaughter was harmless for the same
    reason. The jury's finding that appellant violated section 273ab necessarily includes
    13
    a finding that appellant acted with a higher degree of culpability than that required
    for involuntary manslaughter. The finding that appellant acted intentionally, rather
    than negligently, and with a degree of force exceeding that required to commit
    misdemeanor battery "precludes any possible error in the refusal to instruct on
    involuntary manslaughter. [Citation.]" (People v. Gutierrez (2002) 
    28 Cal. 4th 1083
    , 1145.)
    Ineffective Assistance of Counsel
    Appellant contends his Sixth Amendment right to be represented by
    effective counsel at trial was violated because the conduct of his retained trial
    counsel fell below the applicable standard of care in several ways. Specifically,
    appellant contends his defense counsel at trial rendered ineffective assistance
    because trial counsel failed to (1) impeach the testimony of Jayden's mother with
    her prior inconsistent statements concerning the dates on which Jayden accidently
    hit her head in the bathtub and in a driveway fall; (2) call expert witnesses in
    neurology and pathology to counter the expert medical opinions offered by Doctors
    Nguyen and Berkowitz; (3) call a psychologist as an expert witness to testify that
    appellant's "nature" is not "consonant" with that of a child abuser; and (4) interview
    or call Anna Mena, a witness who would have testified that appellant was visibly
    upset, emotional and in extreme distress after Jayden was transported to the
    hospital.
    "To secure reversal of a conviction upon the ground of ineffective
    assistance of counsel under either the state or federal Constitution, a defendant must
    establish (1) that defense counsel's performance fell below an objective standard of
    reasonableness, i.e., that counsel's performance did not meet the standard to be
    expected of a reasonably competent attorney, and (2) that there is a reasonable
    probability that defendant would have obtained a more favorable result absent
    counsel's shortcomings. [Citations.]" (People v. Cunningham (2001) 
    25 Cal. 4th 926
    , 1003.) When a claim of ineffective assistance of counsel is raised on appeal,
    the appellant "must establish deficient performance based upon the four corners of
    14
    the record." (Ibid.) If the appellate record "fails to show why counsel acted or
    failed to act in the instance asserted to be ineffective, unless counsel was asked for
    an explanation and failed to provide one, or unless there simply could be no
    satisfactory explanation, the claim must be rejected on appeal. [Citation.]" (People
    v. Kraft (2000) 
    23 Cal. 4th 978
    , 1068-1069.) As a consequence, "claims of
    ineffective assistance are often more appropriately litigated in a habeas corpus
    proceeding." (People v. Mendoza Tello (1997) 
    15 Cal. 4th 264
    , 266-267.)
    Here, the record on appeal does not show why appellant's trial counsel
    did not use the impeachment material or call the expert and percipient witnesses
    appellant highlights. We cannot adequately evaluate appellant's contentions in the
    absence of evidence explaining trial counsel's conduct or demonstrating his refusal
    to supply such an explanation. As our Supreme Court explained in Mendoza Tello:
    "An appellate court should not . . . [evaluate factual claims outside the record on
    appeal], set aside a jury verdict, and brand a defense attorney incompetent unless it
    can be truly confident all the relevant facts have been developed . . . ." (People v.
    Mendoza 
    Tello, supra
    , 15 Cal.4th at p. 267.) We can have no such confidence here
    because the record on appeal contains no information about trial counsel's
    reasoning. At the same time, we cannot say there "simply could be no satisfactory
    explanation" for the choices trial counsel made. It may be the case that trial counsel
    was unable, after a reasonable search, to find expert witnesses willing to support the
    defense theory of the case, or that he made a reasoned tactical choice to avoid
    impeaching the testimony of a grieving mother.
    Under these circumstances, we decline to consider appellant's
    ineffective assistance claim on its merits. The claim is more appropriately raised in
    a petition for writ of habeas corpus.2 (People v. Mendoza 
    Tello, supra
    , 15 Cal.4th at
    p. 267; People v. Mayfield (1993) 
    5 Cal. 4th 142
    , 188.) For the same reason, we
    decline to consider appellant's contention that the cumulative effect of trial counsel's
    2
    Appellant's petition for writ of habeas corpus (No. B254062) is pending and will
    be decided by separate order.
    15
    omissions was prejudicial and resulted in a denial of his Sixth Amendment right to
    effective assistance of counsel.
