The court vacated the manslaughter sentence, not the conviction
Arizona’s Court of Appeals on September 30 set aside Gabriel Paul Horcasitas’ 10.5-year manslaughter sentence after ruling that an AI-generated video depicting the victim influenced the sentencing judge. The court upheld Horcasitas’ conviction and sent the case back for resentencing. Its opinion draws a distinction between actual recordings of Christopher Pelkey and AI-created speech and behavior presented as if they came from him.
“The AI video presents a depiction of the victim and his thoughts created from the imaginings of the victim’s sister,” the court wrote in State v. Horcasitas. The judges said the video did not document an actual event and gave the sister’s interpretation of what Pelkey might have said the appearance of Pelkey speaking for himself.
The ruling leaves Horcasitas’ manslaughter conviction intact. It vacates that offense’s sentence and orders a new sentencing hearing; the appeal also involved an endangerment conviction, which the court did not disturb.
A generated message appeared to speak in Pelkey’s voice
Pelkey was killed in a 2021 road-rage shooting in Chandler. At the May 2025 sentencing hearing, family members and friends described their grief, and Pelkey’s brother read a statement Pelkey had written. His sister then spoke about wondering what her brother would have said if he could address the courtroom.
The video that followed depicted Pelkey speaking to the camera, using his picture and voice profile. It included real recordings of him discussing his faith and fishing, but also AI-generated sections. In those sections, the depicted Pelkey described the video as a true representation of him and told Horcasitas, “I believe in forgiveness and in God who forgives.”
The sentencing judge praised the video, saying, “I loved that AI,” and described Pelkey’s forgiveness as genuine and coming from his heart. The judge imposed the presumptive 10.5-year manslaughter term. Prosecutors had asked for nine years; Horcasitas’ lawyer sought seven, citing mitigating circumstances that included his lack of a criminal history.
The judges focused on reliability and due process
Arizona law gives victims the right to speak at sentencing, and the court acknowledged that victims’ statements are not testimony subject to the usual disclosure requirements or cross-examination. But that right does not remove a defendant’s right to a fair sentencing process. The court said sentencing information must have at least a minimal indication of reliability.
The state argued that Pelkey’s sister knew him well, that the video reflected what she believed he would have said, and that its message matched his written beliefs. The court rejected those points as enough to make the AI-generated portrayal reliable. It said the lifelike presentation erased the difference between the family’s view of Pelkey and Pelkey’s own words and opinions.
The panel also concluded that the video affected the judge, even though the record did not show exactly how much weight it carried. “There is no question it played a role,” the opinion states. Because the sentencing judge cited the AI portrayal while explaining the sentence, the court found its use prejudiced Horcasitas and made the proceeding fundamentally unfair.
Actual recordings remain distinct from AI-generated speech
The opinion does not bar family members from addressing a court or rule out all video at sentencing. It distinguishes the embedded real footage of Pelkey, which the court said was permissible, from generated material that made invented speech and facial expressions appear to come directly from him. The ruling turns on the video’s role in this sentencing and its presentation as the victim’s own thoughts.
At resentencing, the court must impose a new manslaughter sentence without relying on the AI-generated portrayal. Horcasitas remains convicted; the appellate decision does not decide what sentence he will receive at the new hearing.
