         v.

PETER SHUI,

         Defendant and Appellant.



         A jury found defendant Peter Shui guilty of second degree murder and found true
an allegation that he used a deadly weapon in the commission of the offense. (Pen.
Code, §§ 187, 12022, subd. (b)(1).)1 The trial court sentenced defendant to an aggregate
term of 16 years to life in prison.
         Defendant raises two claims on appeal. At the time of the offense, defendant and
the victim, Lijia Zheng, were arguing in Mandarin when Zheng described defendant’s
wife in profane terms. Defendant contends the trial court erred by excluding expert
testimony that the words Zheng used were “uniquely provocative” in Chinese culture.
Defendant claims the trial court thereby violated his federal constitutional rights by
denying him the opportunity to present a heat of passion defense. Second, defendant



         1
             Subsequent undesignated statutory references are to the Penal Code.
claims the trial court erred by giving the jury conflicting instructions on the intent
required for involuntary manslaughter.
       We conclude the trial court did not err in either respect. We will affirm the
judgment.
                       I. FACTUAL AND PROCEDURAL BACKGROUND
   A. Facts of the Offense
       The evidence is undisputed that defendant killed his paramour, Lijia Zheng, by
stabbing her multiple times with a kitchen knife in August 2011. Defendant was
intoxicated on alcohol and Xanax at the time. His defense focused on his state of mind at
the time of the offense.
       1. Defendant’s Testimony
       Defendant, 48 years old at the time of the offense, was married with two children.
He immigrated to the United States from Taiwan with his wife in 1990. He initially
worked at technology companies run by his brothers, but he quit working regularly in
December 2006. At the time of the offense, defendant earned about $1,000 a month
playing mahjong several times a week.
       At trial, defendant testified as follows. He met Zheng while playing mahjong in
2007. They soon became friends and began having sex in 2008. Defendant’s wife
discovered the affair and became angry, but the couple remained married. Defendant
ended his relationship with Zheng for a few months in 2009, but he later resumed the
affair. Defendant’s wife and daughter were aware of the ongoing affair, but defendant
said he could not stop himself from seeing Zheng.
       On the morning of August 3, 2011, defendant’s wife saw Zheng at a supermarket
carrying an expensive handbag, which the wife mistakenly believed defendant had
purchased. The wife, angry at defendant for living “the high life” with Zheng, called him
on the phone to scold him. Afterwards, defendant immediately called Zheng and told her



                                              2
his wife was upset about the handbag. Zheng advised defendant to let his wife vent and
told him not to argue with her.
       The next day, defendant played mahjong while Zheng went furniture shopping
with friends. Defendant began drinking red wine during the game. When the game
ended, Zheng was having dinner with her friends, so defendant went home to his wife.
He opened another bottle of red wine and continued drinking. Later in the evening,
Zheng invited defendant to come to her apartment for the night. After Zheng pleaded
with him several times to join her, defendant finally agreed, so Zheng drove to his house
to pick him up. Defendant brought another bottle of red wine with him. He remembered
being in the car with Zheng on Interstate 280 and seeing the exit for Wolfe Road, but he
testified that things became vague after that.
       Defendant could not recall arriving at Zheng’s apartment, but he recalled drinking
more wine when he was there. His habit was to sit in the bathroom with Zheng and talk
with her while she showered. He could not specifically recall doing so that night, but he
did recall Zheng washing her face and wearing his pajamas. The next thing he could
remember was Zheng saying: “Fuck your mother. That silly cunt of yours. [¶] She
thought you bought me the bag.”2 This was a reference to defendant’s wife. Zheng had
never said anything like that before, and she had never used that kind of language before.
Defendant could not recall what he said to Zheng in response. When defense counsel
asked defendant how Zheng’s statement made him feel, defendant responded: “I cannot
describe. Up until today, I still don’t know how.” When counsel repeated the question,
defendant added: “How could she have possibly said such a thing because sometimes
when we talked about arguments between my wife and I, she would actually to try [sic]
talk me out of it.” Defendant could not recall if he told Zheng not to repeat the statement.
He could not recall if she said it more than once.

       2
         Defendant testified through a Mandarin interpreter. The quoted text is the
interpreter’s English translation of defendant’s testimony.

                                                 3
       Defendant testified that the next thing he remembered was feeling like he had
killed Zheng. He remembered going to the kitchen, but he did not recall getting a knife.
He testified that he did not want to kill Zheng, and he did not know how it happened. At
first, he testified that he could not remember stabbing her at all, but he then added that he
had “a little bit of a memory” of stabbing her in the neck. His next memory was that his
hands were in pain and that he was bleeding. He remembered going to the bathroom to
wash his hands, and he remembered moving Zheng’s cell phone. Then he went to the
kitchen and tried to wrap plastic wrap around his head so he could no longer breathe.
After finding he could still breathe, he applied another piece of plastic wrap to his head.
When he could no longer breathe, he took off the plastic wrap and called 911.
       Defense counsel again asked defendant if Zheng’s statement about his wife had
made him angry. Defendant testified that “I think it must have,” but stated: “I don’t
remember how I felt.” He added: “When she was saying those words, I look at her face
and her face turned into one of a ghost, and it was approaching me like that.” When
defense counsel asked defendant if he killed Zheng because of her statement, he
responded: “I don’t know how to say whether yes or no. [. . .] We didn’t even argue.
How did I end up killing her? I never thought about killing her.”
       On cross-examination, defendant testified that Zheng had loaned him about
$11,000 or $12,000. But he testified that he repaid the loan by having his brother wire
money to Zheng’s bank account. He denied owing Zheng money at the time of the
offense in August 2011, but he admitted that he was financially distressed and bankrupt
at the time. Defendant could not recall if he had taken Xanax on the night of the offense.
When shown the knife he used to stab Zheng, defendant testified that he could not recall
using the knife to stab her, but he admitted that he could recall washing it in the kitchen
sink. When asked if he killed Zheng because of what she said about his wife, defendant
responded: “I really don’t know if that was why. I’m just stating what I remember and
to answer the questions that you’re asking.”

                                               4
       2. The 911 Call
       Defendant called 911 at 2:36 a.m. on August 5, 2011. An audio recording of the
call was played for the jury. Defendant requested a Mandarin translator, who interpreted
for him during the call.3 Defendant said: “I, I kill my girlfriend. [. . .] I, I, I just come
to, uh, I just want to admit this, this happening.” Defendant said it had happened a half-
hour ago. When asked how he killed his girlfriend, he stated: “I don’t know what I used
to kill her. I, I drink too much.”
       After the operator again asked defendant how he killed her, he responded:
“Because she’s, uh, yelling at me, yelled at me, so I used a knife to kill her.” He said
Zheng’s body was in the bedroom. He subsequently added: “I injure her so many places
because she keep yelling at me.” The operator asked if he had been diagnosed with
anything or whether he was hearing voices, and defendant responded: “I, I can’t tell you
right now because I drink too much.” He stated that he had used a kitchen knife, and
said: “I’m not holding the knife. I know that’s evidence. So I don’t know what to do
with that. Please tell me.” The operator instructed him to stay on the phone and not to
pick up the knife. Defendant then provided instructions on how the police could get into
the apartment complex.
       When the operator asked again whether defendant had any mental illness, he said
he had high blood pressure and “mental problem causing [sic] by the high blood
pressure.” He then clarified: “My mental problem causing [sic] by my girlfriend.” He
said he had not been diagnosed by a doctor. He said he took medicine for high blood
pressure, and that he had taken a sleeping pill the night before.

       3. Police Investigation
       Police arrived while defendant was on the phone with the 911 operator. The
operator instructed defendant to go to the front door of the apartment with his hands up.
Police outside the apartment yelled for defendant to exit with his hands in sight.
Defendant obeyed, and police took him into custody. Defendant had an “unsteady gait”
and his shirt was covered in blood. He had blood on his hands, and his left index finger
had suffered a significant cut. The parties stipulated that analysis of blood drawn from
defendant at 7:28 a.m. revealed a blood alcohol level of 0.14 percent and showed the
presence of Xanax and blood pressure medication.
       Upon entering the apartment, police found Zheng’s body lying face down on the
bedroom floor with a curtain panel over her head. The body had suffered numerous knife
wounds, including three potentially fatal stab wounds to the neck and chest area. A large
kitchen knife was found near the bed. The parties stipulated that the knife was used to
kill Zheng. Police found blood in every room of the apartment.
       Neighbors in the apartment below heard several loud thuds and crashing noises
from Zheng’s apartment around 1:10 a.m. They also heard sounds like a woman crying
or moaning, and yelling or arguing in a language other than English. The yelling or
argument lasted around 10 or 15 minutes. It was not the first time the neighbors had
heard arguments coming from Zheng’s apartment.
       4. Defendant’s Statements to His Brother
       Defendant’s brother, Paul Hsu, testified for the prosecution as follows.4
Defendant had worked for Hsu’s computer company, but the company went bankrupt in
2001. As defendant struggled financially, he had difficulty transitioning to a less
extravagant lifestyle. Defendant began living on his mahjong winnings. He also

        Hsu testified through a Mandarin interpreter. All quotes of Hsu’s testimony are
from the interpreter’s English translation.

                                             6
gambled at casinos. He lost his house and declared bankruptcy at least once. Zheng was
giving him money, and he felt bad about it.
       Hsu spoke to defendant in jail shortly after Zheng’s death. According to Hsu,
defendant recounted the events leading up to the killing as follows. Zheng had invited
defendant to her apartment that evening. Defendant resisted at first, but he then relented,
whereupon Zheng picked him up and drove them to her apartment. They were both
drinking a lot of wine. Zheng was taking a shower, and when she came out, she started
cursing defendant’s wife using profanities in a loud voice. Zheng said, “Fuck you. That
silly cunt at your house. She thought that you spent money to buy me an LV bag.”
Defendant told her not to say that, but Zheng repeated the profanity. Defendant told her,
“Don’t say that again.” Defendant warned her two or three times, but Zheng kept
repeating the same profanities. Defendant went to the kitchen to get a knife and warned
Zheng not to say it again, but Zheng repeated it. Defendant then killed Zheng with the
knife. Hsu and defendant talked about what had made Zheng angry at defendant’s wife.
Defendant said it was probably because his wife had seen Zheng at the supermarket the
day before. Hsu could not remember whether defendant said it was his wife or Zheng
who was carrying a name brand handbag.
       5. Expert Testimony on the Effects of Alcohol and Xanax
       James Norris, a forensic scientist, testified for the defense concerning the effects
of alcohol and Xanax. Based on the results of defendant’s blood level analysis, Norris
estimated that a person in similar circumstances would have had a blood alcohol
concentration of about 0.26 percent around the time of the offense. He testified that most
people with that alcohol level would show symptoms of intoxication associated with a
person who is “drunk.” They would have some difficulty knowing what is going on
around them, but not to the degree of being comatose. Their ability to recall events
would also be affected. There is an effect of alcohol-induced amnesia, which is
sometimes called a “blackout.” For example, in the morning, a person may not

                                              7
remember what happened the night before. A person may also become intoxicated to the
point where they are physically active, but they are not conscious of it. Norris also
testified that Xanax, like alcohol, is a central nervous system depressant. When
combined, the effects of Xanax and alcohol are additive, meaning that Xanax would
exacerbate the effects of alcohol.
       On cross-examination, Norris testified that he did not know if defendant suffered
from alcohol-induced amnesia regarding his killing of Zheng. The prosecutor questioned
Norris about various statements defendant made in the 911 call and whether they showed
that he recalled how he killed Zheng. Norris testified that defendant’s statement that the
victim was yelling at him and his acknowledgement of the knife as evidence show that he
knew and recalled what he had done. However, defendant’s statement to the effect that
he did not know what he had done supported the possibility of alcohol-induced amnesia.
Norris agreed that defendant’s statements to his brother recounting the facts of the killing
were inconsistent with alcohol-induced amnesia. On redirect, Norris agreed that it was
possible defendant did not know what was happening at the time of the offense, but that
he pieced it together in the time between the killing and the 911 call.
       Dr. Douglas Tucker testified for the prosecution as an expert on the combined
effects of alcohol and drugs. He testified that a person experiencing a blackout may be
physically active and may have short-term memory, but the memories do not get
converted into long-term memory. Based on a hypothetical question, Dr. Tucker testified
that a person calling 911 at 2:36 a.m. and describing what happened at 1:10 a.m.,
followed by recounting the events to a relative at a later time, was not consistent with
alcohol-induced amnesia. He testified that if a memory has not moved into long-term
memory, it cannot be retrieved at a later time. The fact that defendant recalled the event
at a later time showed that it had moved into his long-term memory. Based on his review
of the 911 call and defendant’s statements to his brother, Dr. Tucker testified “with
medical certainty” that defendant had not suffered from an alcohol-related blackout.

                                             8
       On cross-examination, Dr. Tucker testified that a “brownout” is a fragmentary
blackout, where some events can be recalled, but memory is hazy. For some people who
experience a brownout, recall can get better over time. Dr. Tucker testified that it was
possible, but unlikely, that defendant had suffered from a brownout. On redirect,
Dr. Tucker opined with “reasonable medical certainty” that defendant did not suffer a
blackout or brownout.
   B. Procedural Background
       On April 19, 2012, the prosecution filed an information charging defendant with
murder. (§ 187.) The information further alleged that defendant personally used a deadly
and dangerous weapon—a knife—in the commission of the offense. (§ 12022, subd.
(b)(1).) Defendant pleaded not guilty. He also pleaded not guilty by reason of insanity.
       On February 20, 2013, the jury found defendant guilty of second degree murder
and found the deadly weapon use allegation to be true. Following the sanity phase of the
trial, the jury found him sane at the time of the offense. On April 26, 2013, the court
sentenced defendant to a term of 15 years to life for the murder conviction with a
consecutive one-year term for the enhancement.
                                        II. DISCUSSION
   A. Exclusion of Testimony on the Cultural Significance of the Victim’s Statements
       Defendant contends the trial court erred by excluding expert testimony that the
words Zheng used to describe his wife were “uniquely provocative” in Chinese culture.
Defendant argues the testimony was relevant to the jury’s determination of whether he
was guilty of voluntary manslaughter based on a defense of heat of passion. He argues
the ruling denied him the right to present a defense in violation of the Fifth, Sixth, and
Fourteenth Amendments. The Attorney General argues that the trial court properly
excluded the testimony because the evidence was irrelevant to the objective component
of the heat of passion defense. The Attorney General concedes that the evidence
arguably could have been relevant to defendant’s subjective state of mind, but she argues

                                              9
that defendant never testified that Zheng’s statements caused him to act from passion
instead of reason.
       We conclude that the trial court did not abuse its discretion by excluding the
expert testimony. Even assuming the trial court erred, any error was harmless because
defendant did not demonstrate a reasonable likelihood that the jury would have reached a
more favorable outcome if the testimony had been admitted.
       1. Relevant Procedural Background
       Defendant moved in limine to admit expert testimony from Dr. David Kan, a
forensic psychiatrist and medical examiner who had interviewed appellant about his
mental state at the time of the crime, among other things. Dr. Kan is second-generation
Taiwanese and “well versed in Chinese culture from both personal and professional
experience . . . .” Defendant proffered testimony from Dr. Kan that Zheng’s words were
“ ‘uniquely provocative,’ similar to using the ‘N-word’ in American culture.” Dr. Kan
would further opine that “a raw translation is not sufficient in demonstrating the meaning,
implications and culturally-specific impacts that certain phrases or turns of speech can
have on an individual.”
       At oral argument on the motion, defense counsel argued that the testimony was
relevant to the jury’s consideration of “whether a person of average disposition in the
same position and knowing the same facts would have acted from passion rather than
judgment.” He referred to cases in which the jury was allowed to consider whether the
defendant “reacted as a typical Asian-American would; as a typical Japanese person
would.” The prosecutor opposed the motion on the ground that defendant had failed to
lay a sufficient foundation for Dr. Kan’s testimony. The prosecutor also opposed a heat
of passion instruction.
       The trial court ruled that the proffered testimony was not relevant to the issue of
whether the provocation was such that a reasonable person would act out of passion
rather than reason. The trial court noted that the standard was an objective one based

                                             10
solely on how a reasonable person would act: “It is a reasonable man. It is not a
reasonable drunk person, and it is not a reasonable Taiwanese person or reasonably drunk
Taiwanese person.” In support, the court cited People v. Romero (1999)
69 Cal.App.4th 846 (Romero) [expert testimony on sociology of poverty and Hispanic
culture was irrelevant to whether defendant believed he was in imminent danger and
whether his belief was objectively reasonable]. However, the court added that if
defendant were to testify that he acted out of passion rather than reason in reaction to
Zheng’s words, then the expert’s testimony might be relevant and admissible to the
subjective element of heat of passion. The court also ruled that if defendant so testified,
then the court would hold a hearing under Evidence Code section 402 to determine
whether the expert’s testimony was admissible. In his testimony, however, defendant
was unable to recall how he felt or what he said in reaction to the victim’s statements.
       At the close of evidence, the trial court instructed the jury on first degree murder,
second degree murder, voluntary manslaughter, and involuntary manslaughter. The court
also used the language of CALCRIM No. 570 to instruct the jury on the defense of heat
of passion. In closing argument, defendant argued that he was guilty of “heat of passion
manslaughter” because the victim’s statements caused him to react from passion rather
than reason, thereby negating malice.
       2. Legal Principles
       “ ‘Relevant evidence’ means evidence, including evidence relevant to the
credibility of a witness or hearsay declarant, having any tendency in reason to prove or
disprove any disputed fact that is of consequence to the determination of the action.”
(Evid. Code, § 210.) But expert testimony, even when relevant, is limited to an opinion
that is “[r]elated to a subject that is sufficiently beyond common experience that the
opinion of an expert would assist the trier of fact.” (Evid. Code, § 801, subd. (a).)
       Defendant argues that the excluded testimony was relevant to prove his defense of
heat of passion. Heat of passion is “a state of mind caused by legally sufficient

                                             11
provocation that causes a person to act, not out of rational thought but out of
unconsidered reaction to the provocation.” (People v. Beltran (2013) 56 Cal.4th 935, 942
(Beltran).) “[T]he provocation must be one that would cause an emotion so intense that
an ordinary person would simply react, without reflection.” (Id. at p. 949, original
italics.) But the provocation is not required to be so great as to be “of a kind that would
cause an ordinary person of average disposition to kill.” (Id. at p. 935, original italics.)
       The provocation requirement has two components—“ ‘both an objective and a
subjective component. [Citation.] First, the defendant must actually, subjectively, kill
under the heat of passion.’ ” (People v. Manriquez (2005) 37 Cal.4th 547, 584
(Manriquez).) The passion aroused need not be anger or rage, but may be any violent,
intense, high-wrought, or enthusiastic emotion other than revenge. (People v. Breverman
(1998) 19 Cal.4th 142, 163 (Breverman).) “ ‘But the circumstances giving rise to the
heat of passion are also viewed objectively. As [the California Supreme Court] explained
long ago . . . , “this heat of passion must be such a passion as would naturally be aroused
in the mind of an ordinarily reasonable person under the given facts and circumstances,”
because “no defendant may set up his own standard of conduct and justify or excuse
himself because in fact his passions were aroused, unless further the jury believe that the
facts and circumstances were sufficient to arouse the passions of the ordinarily reasonable
man.” ’ [Citation.]’ ” (Manriquez, supra, at p. 584.) No specific type of provocation is
required. (Breverman, supra, 19 Cal.4th at p. 163.) Legally sufficient provocation may
be entirely verbal, including words of abuse, insult or reproach. (People v. Valentine
(1946) 28 Cal.2d 121, 140; People v. Le (2007) 158 Cal.App.4th 516, 526.)
       3. Standard of Review
       “ ‘In determining the admissibility of evidence, the trial court has broad
discretion.’ [Citation.] In particular, a trial court’s decision on the admissibility of expert
testimony is reviewed for an abuse of discretion. [Citation.]” (People v. Lucas (2014)
60 Cal.4th 153, 226.)

                                              12
       4. Exclusion of the Expert Testimony
       Defendant contends the trial court should have admitted the proffered expert
testimony with respect to the objective component of his heat of passion defense. He
argues that the objective component is defined according to how a reasonable person
would react under the same “facts and circumstances.” Defendant argues that these facts
and circumstances included his cultural heritage, about which the expert would have
testified. Defendant contends this is distinct from redefining the “reasonable person”
standard to be that of a “reasonable Taiwanese person.” To support his argument,
defendant relies primarily on People v. Humphrey (1996) 13 Cal.4th 1073 (Humphrey).
       Humphrey concerned the admission of expert testimony regarding battered
women’s syndrome, since renamed “intimate partner battering.” (See, e.g., People v.
Dowdell (2014) 227 Cal.App.4th 1388, 1416.) The court held that such expert testimony
is generally relevant to the subjective existence and objective reasonableness of the
defendant’s belief in the necessity of self defense. (Humphrey, supra, 13 Cal.4th at
p. 1076.) The court observed that the objective reasonableness of the defendant’s belief
must be considered from the perspective of “ ‘a reasonable person in a similar situation
and with similar knowledge.’ ” (Id. at pp. 1082-1083 [quoting CALJIC No. 5.50].)
Furthermore, “ ‘a defendant is entitled to have a jury take into consideration all the
elements in the case which might be expected to operate on his mind.’ ” (Humphrey, at
p. 1083 [quoting People v. Smith (1907) 151 Cal. 619, 628].) Accordingly, the court
held: “Although the ultimate test of reasonableness is objective, in determining whether
a reasonable person in defendant’s position would have believed in the need to defend,
the jury must consider all of the relevant circumstances in which defendant found
herself.” (Humphrey, at p. 1083.) The court rejected the Attorney General’s claim that it
was “changing the standard from objective to subjective, or replacing the reasonable
‘person’ standard with a reasonable ‘battered woman’ standard.” (Id. at p. 1087.) Thus,



                                             13
the court noted: “Our decision would not, in another context, compel adoption of a
‘ “reasonable gang member” standard.’ ” (Ibid.)
       Here, defendant argues that evidence concerning the provocative nature of the
victim’s statements in Chinese culture, like the expert testimony in Humphrey, was
relevant to prove the external circumstances in which defendant found himself and how
those circumstances “might [have been] expected to operate on his mind.” (Humphrey,
supra, 13 Cal.4th at p. 1083.) Arguably, this is a valid theory of relevance. But the
defendant in Humphrey also gave testimony establishing her own subjective belief in the
necessity of self defense. As three concurring justices noted in Humphrey: “Expert
testimony is [. . .] not relevant until the defendant puts at issue conduct or circumstances
the jury might not otherwise understand as the basis for self-defense. . . .” (Id. at p. 1098
[conc. opn. of Brown, J.].) At the very least, then, a defendant would have to adduce
some testimony or evidence setting forth a basis for the assertion of the defense at issue.
Here, for example, defendant could have put forth evidence establishing that he
subjectively acted out of passion rather than reason due to the provocative nature of the
victim’s statements.
       Defendant made no such showing. He could not recall precisely how he reacted or
what he said in response to the victim’s insults. When his attorney asked him how
Zheng’s statements made him feel, he responded: “I cannot describe. Up until today, I
still don’t know how.” When the prosecutor asked him on cross-examination whether he
killed Zheng because of her statements, defendant responded: “I really don’t know if that
was why.” Thus, the record holds no evidence showing defendant killed Zheng out of
passion rather than reason. Defendant points to statements he made to his brother:
“[A]fter the victim called his wife a ‘silly cunt’ he warned her not to say it again but she
kept saying it, and it was only after her repetition of this slur that he rushed to the kitchen
to get a knife, warned her again not to repeat the insult and then stabbed her when she
did.” This suggests defendant acted out of anger, but the presence of anger alone is not

                                              14
sufficient to establish heat of passion. Heat of passion is established not solely by the
presence of emotion, but by the lack of reflection or rational thought—in other words,
“unconsidered reaction.” (Beltran, supra, 56 Cal.4th at pp. 942, 949.) It is possible to
formulate one’s actions based on reflection and anger at the same time.
       The trial court partly based its ruling on the lack of evidence that defendant acted
from unconsidered reaction. Because there is no evidence in the record establishing the
subjective element of heat of passion (i.e., a lack of reflection or rational thought), the
trial court did not abuse its discretion by excluding the proffered expert testimony.
       Even assuming the trial court erred, it is not reasonably probable the jury would
have reached a more favorable outcome in the absence of error. The jury was instructed
on the subjective element of heat of passion, but defendant put forth no evidence on
which the jury was likely to base such a finding. Accordingly, any error would have been
harmless under People v. Watson (1956) 46 Cal.2d 818 (Watson). Defendant contends
the proper standard for harmless error is the “beyond a reasonable doubt” standard set
forth in Chapman v. California (1967) 386 U.S. 18, because the error denied him the
right to present a defense. We disagree. The trial court instructed the jury on heat of
passion, and defense counsel argued it in closing. The trial court’s ruling solely affected
the admission of expert testimony; defendant was not denied the right to present a
defense. Accordingly, any error would have violated solely state law rules of evidence,
not the federal constitution. For these reasons, we conclude any error was harmless, and
defendant’s claim is without merit.
   B. Instructions on Involuntary Manslaughter Based on Unconsciousness
       Defendant contends the trial court erred by giving the jury conflicting instructions
on the level of intent required for a verdict of involuntary manslaughter based on
unconsciousness. Specifically, he argues that the court erroneously instructed the jury
that a verdict of involuntary manslaughter requires general intent, which element is not
required for the jury to find the defendant guilty of involuntary manslaughter based on

                                              15
voluntary intoxication. Because the jury could not have found that defendant harbored
general intent while unconscious, defendant contends the general intent instruction
effectively negated his unconsciousness defense. The Attorney General, relying on
People v. Boyer (2006) 38 Cal.4th 412 (Boyer), contends there was no reasonable
likelihood the jury misunderstood the instructions.
       We are bound by the Supreme Court’s holding in Boyer. (Auto Equity Sales, Inc.
v. Superior Court of Santa Clara County (1962) 57 Cal.2d 450, 455.) Based on Boyer,
we agree with the Attorney General that there was no reasonable likelihood the jury was
confused by the trial court’s instructions. But even assuming the instructions were
erroneous, defendant cannot show he was prejudiced.
       1. Relevant Procedural Background
       The trial court instructed the jury on the level of intent required for involuntary
manslaughter based on CALCRIM No. 252, as follows: “The crime and other allegation
charged in Count 1 require proof of the union or joint operation of act and wrongful
intent. The following lesser crimes and allegations require general criminal intent: [. . .]
The lesser crime of involuntary manslaughter also requires general criminal intent. For
you to find a person guilty of a lesser crime, or to find the allegation true, that person
must not only commit the prohibited act, but must do so with wrongful intent. A person
acts with wrongful intent when he or she intentionally does a prohibited act. However, it
is not required that he or she intend to break the law.” Defendant lodged no objection.
       The court subsequently instructed the jury on unconsciousness due to voluntary
intoxication based on CALCRIM No. 626, as follows: “You may consider evidence, if
any, of the defendant’s voluntary intoxication only in a limited way. You may consider
that evidence only in deciding whether the defendant acted with an intent to kill or the
defendant acted with deliberation and premeditation. A person is voluntarily intoxicated
if he or she becomes intoxicated by willingly using any intoxicating drug, drink, or other
substance, knowing that it could produce an intoxicating factor, willingly assuming the

                                              16
risk of that effect. You may not consider evidence of voluntary intoxication for any other
purpose. Voluntary intoxication may cause a person to be unconscious of his or her
actions. A very intoxicated person may still be capable of physical movement, but may
not be aware of his or her actions or the nature of those actions. A person is voluntarily
intoxicated if he or she becomes intoxicated by willingly using any intoxicating drug,
drink, or other substance, knowing that it could produce an intoxicating effect or
willingly assuming the risk of that effect. When a person voluntarily causes his or her
own intoxication to the point of unconsciousness, the person assumes the risk that, while
unconscious, he or she will commit acts inherently dangerous to human life. If someone
dies as a result of the actions of a person who was unconscious due to voluntary
intoxication, then the killing is involuntary manslaughter. Involuntary manslaughter has
been proved if you find beyond a reasonable doubt that: One, the defendant killed
without legal justification or excuse; Two, the defendant did not act with the intent to kill;
Three, the defendant did not act with a conscious disregard for human life; And four, as a
result of voluntary intoxication, the defendant was not conscious of his actions or the
nature of those actions. The People have the burden of proving beyond a reasonable
doubt that the defendant was not unconscious. If the People have not met this burden,
you must find the defendant not guilty of murder or voluntary manslaughter.”
       The court then instructed the jury on a misdemeanor manslaughter theory of
involuntary manslaughter: “An unlawful killing resulting from a willful act committed
without intent to kill and without conscious disregard of the risk to human life is
involuntary manslaughter. The defendant committed involuntary manslaughter if: One,
the defendant committed a crime; Two, the defendant committed the crime with criminal
negligence; And 3, the defendant’s acts unlawfully caused the death of another person.
The People allege that the defendant committed a crime that posed a high risk of death or
great bodily injury because of the way it was committed, to wit: Brandishing a deadly
[sic] or deadly weapon.”

                                             17
       In closing argument, defense counsel argued that the jury could find defendant
guilty of involuntary manslaughter based on unconsciousness, and that unconsciousness
would negate intent: “There is another form of manslaughter which the evidence equally
supports and that’s involuntary manslaughter. [. . .] [I]nvoluntary manslaughter occurs
when you are acting even though you don’t realize you’re acting. You’re unconscious in
the legal sense of the word, not the medical sense. The medical sense means you’re just
out, you’re inert. The legal sense is you are acting but you’re not aware of your actions
by way of voluntary intoxication. That also negates intent.” The prosecutor in her
closing argument agreed that the law allowed for a verdict of involuntary manslaughter
based on unconsciousness due to intoxication, but she argued that the evidence did not
support a finding of unconsciousness.
       2. Legal Principles
       “When a person renders himself or herself unconscious through voluntary
intoxication and kills in that state, the killing is attributed to his or her negligence in self-
intoxicating to that point, and is treated as involuntary manslaughter.” (People v. Ochoa
(1998) 19 Cal.4th 353, 423.) The trial court has a sua sponte duty to instruct on voluntary
intoxication causing unconsciousness if there is evidence to support such a finding.
(People v. Graham (1969) 71 Cal.2d 303, 317, overruled on other grounds in People v.
Ray (1975) 14 Cal.3d 20, 29, fn. 7.) However, in a noncapital case, a trial court’s
erroneous failure to fully instruct the jury on a lesser included offense is reviewed for
prejudice under Watson, supra, 46 Cal.2d 818: “A conviction of the charged offense may
be reversed in consequence of this form of error only if, ‘after an examination of the
entire cause, including the evidence’ [citation], it appears ‘reasonably probable’ the
defendant would have obtained a more favorable outcome had the error not occurred
[citation].” (Breverman, supra, 19 Cal.4th at p. 178.)
       3. Defendant Suffered No Prejudice From the Court’s Instructions



                                               18
       The California Supreme Court previously considered the argument raised here in
Boyer, supra, 38 Cal.4th 412. In Boyer, the jury was instructed with a version of
CALJIC No. 8.47 that if Boyer, while unconscious as the result of voluntary intoxication,
killed without malice or an intent to kill, he would be guilty of involuntary manslaughter.
(Boyer, supra, at p. 473.) The trial court further instructed the jury on a misdemeanor
manslaughter theory of involuntary manslaughter based on CALJIC No. 8.45. Finally,
the trial court instructed the jury that involuntary manslaughter was a general intent
offense, requiring a union or joint operation of act or conduct and general intent.
       On appeal, Boyer put forth an argument identical to defendant’s argument here.
(Boyer, supra, 38 Cal.4th at pp. 473-474.) The California Supreme Court rejected
Boyer’s claim on the basis that there was no reasonable likelihood the instructions
confused or misled the jury about the connection between unconsciousness due to
voluntary intoxication and involuntary manslaughter. (Id. at p. 474.) The court noted
that the jury had been specifically instructed that an unintentional killing while
unconscious due to voluntary intoxication was involuntary manslaughter. The court
further noted that the jury had been instructed on a distinct theory of involuntary
manslaughter, e.g., misdemeanor manslaughter. The court held: “Under these
circumstances, there seems little chance the jury would conclude that the instruction
defining involuntary manslaughter as a general intent crime negated the instruction
defining an unintentional homicide while unconscious from voluntary intoxication as
involuntary manslaughter, and thus precluded such a conviction based on voluntarily
induced unconsciousness.” (Ibid., original italics.) The same circumstances are present
in this case such that the court’s logic in Boyer applies with equal force here.
       Defendant relies on a passage in Boyer wherein the California Supreme Court
noted that the trial court had orally modified the relevant instruction. With respect to
involuntary manslaughter, the trial court had specified that general intent is presumed
insofar as the defendant committed the underlying criminal act. (Boyer, supra,

                                             19
38 Cal.4th at p. 475.) Defendant argues that Boyer is thereby distinguishable because the
trial court here made no such modification. But the fact of the trial court’s oral
modification in Boyer was not dispositive in the court’s analysis.
         Even assuming the trial court’s instructions were erroneous, defendant cannot
show a reasonable probability the jury would have reached a more favorable outcome in
the absence of such error. The prosecution’s expert testified to a “medical certainty” that
defendant did not suffer from alcohol-induced amnesia because he was later able to
recount specific facts of the offense, e.g., the 911 call and his conversation with his
brother while in jail. By contrast, defendant’s expert provided little or no basis to support
a finding that defendant was unconscious at the time of the killing. Based on this record,
it is not reasonably probable the jury would have found defendant was unconscious if it
had been instructed as defendant now contends it should have been instructed.
         For these reasons, we conclude defendant’s claim of instructional error is without
merit.
                                      III.   DISPOSITION
         The judgment is affirmed.
