I. INTRODUCTION

A jury convicted Steven George Ambriz of murder and unlawful possession of a firearm and ammunition. Ambriz seeks reversal of that

conviction, arguing the trial court inadequately investigated potential juror

misconduct. Ambriz also raises several claims of prosecutorial error.1 We disagree with Ambriz’s contentions and affirm.

II. BACKGROUND

In December of 2021, Ambriz shot Jordan Schmidt six times, killing him. Prior to the shooting, the two men were arguing over a firearm that Schmidt had given to Ambriz. According to witness Carlos Salazar, Ambriz held Schmidt at gunpoint while he directed Salazar to drive them to the site of the homicide near the edge of Brawley. Once arriving at the desired location, Ambriz killed Schmidt.

In 2022, the Imperial County District Attorney’s Office charged Ambriz

with murder (Pen. Code,2 § 187, subd. (a); count 1), kidnapping (§ 207, subd. (a); count 2), possession of a firearm by a felon (§ 29800, subd. (a)(1); count 3), and unlawful possession of ammunition (§ 30305, subd. (a)(1); count 4). Prosecutors alleged a kidnapping special circumstance for the murder (§ 190.2, subd. (a)(17)(B)) and that Ambriz personally and intentionally discharged a handgun causing great bodily injury and death in counts 1 and 2 (§ 12022.53, subds. (b)–(d)).

While the jury deliberated in Ambriz’s 2024 trial, the court received a note from juror number 9 (Juror No. 9) stating, “ ‘I would like to speak to the

1 Ambriz uses the term “prosecutorial misconduct,” but that “ ‘is somewhat of a misnomer to the extent that it suggests a prosecutor must act with a culpable state of mind. A more apt description of the transgression is prosecutorial error.’ ” (People v. Daveggio and Michaud (2018) 4 Cal.5th 790, 853.)

judge regarding a concern regarding continuing to serve on this jury.’ ” In response, the trial court questioned Juror No. 9 as follows:

The Court: Okay. Does the concern relate to something outside the deliberation process or is it something inside the deliberation process? Juror No. 9: Well, I mean, it’s regarding a comment that was said during jury — The Court: Okay. Somebody said something. Was it something to you? Juror No. 9: Something generally. The Court: Just a general statement? Juror No. 9: Uh-huh. The Court: Okay. And — and you — you — you didn't agree with that or you had a problem with that? Juror No. 9: Uh-huh. Yes.

The Court: Okay. All right. I — I understand your concern. Is that your only concern? Juror No. 9: Yes. The Court: Okay. Do you feel, as you sit here, that you can follow the instructions that you were given as far as your duties and obligations as a juror? Juror No. 9: No, your honor. The Court: Okay. How would you have a problem not following the — the instructions? What would be your concern? Juror No. 9: I feel, at this point, I am unable to remain impartial. The Court: Okay. Your impartiality is — is — you — you say you cannot do it and cannot continue to do that? Juror No. 9: Yes. The Court: Okay. All right. Now, impartiality talks about bias against people and — and other things related to the

jury process. That’s what you’re talking about. You don’t feel you can follow that instruction? Juror No. 9: Uh-huh. The Court: Okay. Juror No. 9: Yes, your honor. The Court: Okay. Very good. That’s all the questions I have. The trial court found good cause to excuse Juror No. 9, and it replaced her with an alternate. The trial court denied Ambriz’s requests to further question Juror No. 9 and to ask the entire jury if they heard any inappropriate comments. The trial court explained that if any other jurors had concerns, they were aware that they could communicate with the court by note, and that the comment at issue could have been innocuous or “something that just rubbed Juror No. 9 the wrong way.”

The trial court informed the jury that it granted Juror No. 9’s request to be excused. The trial court reminded the remaining jurors to follow the jury instructions and to inform the court if any of them were unable to do so. The trial court replaced Juror No. 9 with an alternate and instructed the jury to disregard all past deliberations and to start deliberations anew.

The newly constituted jury convicted Ambriz of premeditated first degree murder, finding true the firearm allegations under section 12022.53, subdivisions (b) and (c). The jury also found Ambriz guilty of counts 2 and 3. The jury did not return a verdict on count 2 or the kidnapping special circumstance in count 1, so the trial court instructed them to continue deliberating.

After the alternate juror who replaced Juror No. 9 was hospitalized and replaced with a second alternate juror, the jury was unable to reach a verdict on count 2 or the kidnapping special circumstance in count 1. The trial court

granted the People’s request to dismiss the kidnapping charge and special circumstance.

The trial court sentenced Ambriz to prison for 70 years to life. Ambriz received 25 years to life for count 1, plus 20 years to life for the firearm enhancement under section 12022.53, subdivision (c), plus 25 years for two prior strikes. The trial court imposed but stayed 10 years for the section 12022.53, subdivision (b) enhancement, two years for count 3, and two years for count 4. Ambriz timely appealed.

III. DISCUSSION

A. The Trial Court Did Not Abuse Its Discretion When Investigating the Comment Reported by Juror No. 9 Ambriz argues that the trial court failed to investigate adequately the circumstances leading to Juror No. 9’s dismissal. Ambriz claims that because another juror’s comment caused Juror No. 9 to doubt her impartiality, it called into question whether that other juror committed misconduct and whether that misconduct affected the remainder of the jurors. We disagree.

1. Court’s Duty to Investigate Potential Juror Misconduct “ ‘[C]ourts should exercise caution when undertaking inquiries that threaten to trench on the sanctity of jury deliberations, for the preservation of secrecy during deliberations fosters an atmosphere conducive to a frank and open discussion of the issues among jurors. Ensuring such secrecy also insulates the jury from improper influence that could be brought to bear by outside forces and supports the stability of jury verdicts.’ ” (People v. Zemek (2023) 93 Cal.App.5th 313, 336.) Accordingly, “inquiry into possible grounds for discharging a juror . . . during jury deliberations . . . ‘should be as limited in scope as possible.’ ” (People v. McGhee (2025) 17 Cal.5th 612, 629.)
