The California Court of Appeal recently upheld the conviction of Jessie Cornejo Ambriz, who was found guilty of multiple felonies related to domestic violence against his dating partner, K.R. The court's decision, filed on November 6, 2026, comes after Ambriz raised several claims of error during his appeal, including insufficient evidence and prosecutorial misconduct. The ruling is significant as it reinforces the legal system's stance against domestic violence and the importance of protecting victims.

Ambriz's case began when he started dating K.R. in September 2023. As their relationship progressed, Ambriz exhibited increasingly controlling and jealous behavior. This culminated in a violent incident on November 14, 2023, when K.R. attempted to leave Ambriz's home after he became aggressive when she refused to engage in sexual activity. During this incident, Ambriz physically assaulted K.R., leading to her calling 911 for help. The police later arrested Ambriz after K.R. reported the abuse.

The charges against Ambriz included torture, corporal injury of a dating partner, criminal threats, false imprisonment, kidnapping, and dissuading a witness. He pleaded not guilty, but a jury found him guilty of all charges except for torture. The trial court sentenced him to a total of seven years and four months in prison. Ambriz appealed the judgment, raising multiple claims of legal errors.

In its ruling, the court addressed Ambriz's claims, including his argument that there was insufficient evidence to support his conviction for making a criminal threat. The court found that the evidence presented during the trial was sufficient to support the conviction. The court noted that during the incident, Ambriz threatened K.R. by saying, "That's exactly what I'm going to do" when she expressed fear for her life. The court stated, "Under these circumstances, Ambriz’s threat to kill K.R. was 'so unequivocal, unconditional, immediate, and specific as to convey [to her], a gravity of purpose and an immediate prospect of execution.'"

Additionally, Ambriz challenged the trial court's decision to exclude certain evidence that he believed would impeach K.R.'s credibility. Specifically, he wanted to question her about a potential motive to lie regarding her immigration status. The court ruled that Ambriz could only pursue this line of questioning if he had a good faith basis for it, which he did not. The court emphasized the importance of avoiding prejudicial questioning regarding sensitive topics like immigration status.

Another point of contention was the admissibility of expert testimony regarding the behaviors of domestic violence victims. The court found that the testimony was relevant and necessary to help the jury understand the dynamics of domestic violence, particularly regarding K.R.'s actions and statements after the incident. The court concluded that the prosecutor did not commit misconduct in admitting this expert testimony.

Ambriz also claimed that his trial counsel was ineffective for failing to renew objections to the expert testimony after K.R. and the police officer testified. The court rejected this claim, stating that any further objections would have been meritless, as the expert testimony was relevant to the case.

In terms of sentencing, Ambriz argued that the trial court erred by imposing consecutive sentences without fully understanding its discretion to impose concurrent terms. However, the court determined that the trial court had sufficient grounds to impose consecutive sentences based on the nature of the offenses and the circumstances of the case.

The court ultimately affirmed Ambriz's conviction and remanded the case for clerical corrections in the abstract of judgment. This ruling underscores the court's commitment to addressing domestic violence and ensuring that victims receive protection and justice in the legal system.

Looking ahead, the ruling sets a precedent for similar cases involving domestic violence, emphasizing the importance of victim testimony and the admissibility of expert testimony in understanding the complexities of such cases. It also highlights the legal system's dedication to holding perpetrators accountable and protecting victims from further harm.

Ambriz may have the option to appeal the ruling further, but details regarding any potential future legal actions were not available in the court filing. For now, the court's decision stands as a significant affirmation of the convictions against him.
