IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION ONE

THE PEOPLE, Plaintiff and Respondent, A170937

v. (San Francisco City &County WYN LEUNG, Super. Ct. No. SCN231869) Defendant and Appellant.

After defendant Wyn Leung stabbed his wife to death, a jury convicted him of murder (Pen. Code, § 187, subd. (a)),1 domestic violence (§ 273.5, subd. (a)), and violating a domestic violence protective order resulting in physical injury (§ 166, subd. (c)(2)). The jury also found true that defendant personally used a deadly and dangerous weapon (§ 12022, subd. (b)(1)) and inflicted great bodily injury while committing domestic violence. (§ 12022.7, subd. (e).) For these, and additional crimes to which he pleaded no contest, defendant was sentenced to an aggregate term of 25 years to life. Defendant raises a single issue on appeal—that the trial court erred in giving CALCRIM No. 378, the general consciousness of guilt instruction. The instruction, as edited to reflect the evidence in the case, advised the jury in pertinent part that if defendant “stabbed himself or resisted detention, that

1 conduct may show that he was aware of his guilt.” Defendant does not claim there was no substantial evidence of self-harm, as there was eye-witness testimony that immediately after defendant grabbed and stabbed his wife, he began stabbing himself in the chest and then said, “ ‘I will be in jail, too. I have to kill myself, too[.]’ ” Rather, he asserts that because CALCRIM No. 378 was added to CALCRIM’s compendium of approved instructions four years after he committed the crimes of which he was convicted, giving the instruction violated his due process rights. He also complains the prosecutor did not include the instruction in her pretrial list of requested instructions and asked for the instruction late in the trial, after defendant testified to his self-harm and statement. In addition, he maintains the jury must have improperly relied on the instruction in finding defendant acted with premeditation. We affirm. DISCUSSION2 Due Process Defendant is correct that CALCRIM No. 378 was adopted by the Judicial Council four years after he committed his crimes. (See CALCRIM No. 378 [noting, “New March 2022”].) However, while this instruction may have been a “new” CALCRIM instruction, defendant is incorrect in urging the substance of the instruction was new and therefore including it in the instructions to the jury violated his due process rights. The Judicial Council adopted CALCRIM No. 378 in the wake of People v. Pettigrew (2021) 62 Cal.App.5th 477 (Pettigrew). In that case, the defendant was convicted of first degree murder of his female roommate and on appeal argued, among other things, that the trial court had erred in giving

2 the “standard ‘flight’ instruction” (CALCRIM No. 372), which the prosecutor had then argued to the jury allowed it to consider defendant’s “ ‘attempt[] to commit the ultimate flight after he was in police custody,’ ” namely an attempt to commit suicide. (Pettigrew, at pp. 482, 496.) The Court of Appeal agreed with the defendant that the trial court had erred in giving the standard flight instruction. But not because the law did not recognize that self-harm or attempted self-harm could be evidence of consciousness of guilt. To the contrary, the court cited to case law as early as 1956 recognizing the relevance of such evidence. It explained: “In People v. James (1976) 56 Cal.App.3d 876 . . . , the court observed that, in an appropriate case, a defendant’s postarrest suicide attempt to evade prosecution ‘can be said to constitute circumstantial evidence of guilt,’ and the evidence may support a jury drawing ‘a reasonable inference of consciousness of guilt.’ (James, at p. 890.) Other courts have also recognized that evidence of a defendant’s attempted suicide after the commission of a crime constitutes relevant circumstantial evidence of guilt if the evidence supports an inference that the suicide attempt was an effort to evade prosecution. (People v. Sorrentino (1956) 146 Cal.App.2d 149, 161 . . . [‘There was also evidence of consciousness of guilt on the part of appellant, since he stated that he would have committed suicide if the officers had not taken his gun.’]. . . .)” (Pettigrew, supra, 62 Cal.App.5th at p. 498.) Rather, the Court of Appeal ruled it had been error to give CALCRIM No. 372 because, while “ ‘ “ ‘[f]light requires neither the physical act of running nor the reaching of a far-away haven[,] . . . [f]light manifestly does require . . . a purpose to avoid being observed or arrested.’ ” ’ (People v. Bradford (1997) 14 Cal.4th 1005, 1055.)” (Pettigrew, supra, 62 Cal.App.5th at p. 497.) There was no evidence, however, the defendant had any such

3 purpose. “As defendant contends, he did not ‘flee or try to flee after the crime.’ Instead, when the police arrived to perform a welfare check on Cowen, they discovered defendant lying in his bed in a fetal position. And there is no evidence he tried to escape from custody after his arrest. Therefore, the record simply did not contain substantial evidence to support instructing the jury with CALCRIM No. 372, and the trial court should not have done so.” (Pettigrew, supra, 62 Cal.App.5th at p. 499.) The court went on to observe that “[u]nfortunately, there [was] no general use consciousness of guilt limiting instruction that could have been used here.” (Pettigrew, supra, 62 Cal.App.5th at p. 500.) It urged the Judicial Council to rectify this gap in the CALCRIM instructions, stating: “Because the courts have held evidence of any type of postoffense conduct that tends to prove the defendant’s consciousness of guilt is relevant and may be admissible . . . , pursuant to rule 2.1050(d) of the California Rules of Court, we respectfully suggest the Judicial Council consider drafting a more general instruction that might be used in cases that do not fit within the existing, specific consciousness of guilt instructions.” (Pettigrew, at p. 500, fn. 7.)3 The following year, the Judicial Council did exactly as Pettigrew urged. With the promulgation of CALCRIM No. 378, the Judicial Council provided a template instruction for use in cases in which a consciousness of guilt instruction is appropriate, but the circumstances are other than those

3 The court pointed out the “official California criminal jury instructions promulgated by the Judicial Council include four specific instructions on how a jury may consider evidence of a defendant’s actions as consciousness of his or her guilt. (CALCRIM No. 362 [false statements], No. 371 [suppression & fabrication of evidence], No. 372 [flight] & No. 2130 [refusal to submit to chemical test upon arrest for driving under the influence of alcohol and/or drugs].)” (Pettigrew, supra, 62 Cal.App.5th at pp. 499–500.)

4 addressed by the specific consciousness of guilt instructions (e.g., CALCRIM Nos. 362, 371, and 372). In sum, there is no merit to defendant’s claim that by instructing the jury with CALCRIM No. 378, the trial court subjected defendant to “new” law thereby compromising his due process rights. To the contrary, the law as to which the jury was instructed has been on the books for more than seven decades.
