Arizona appeals court vacated Horcasitas's sentence over an AI 'victim' video. The manslaughter conviction still stands.

Vacating a sentence over an unreliable victim-impact video limits what a judge may rely on at sentencing. It is not a reversal of the manslaughter conviction. The Arizona Court of Appeals, Division One, held that victims have a right to be heard, but that AI portions putting words in Christopher Pelkey's mouth that he never said failed reliability and due-process minimums, while real footage of the victim was permissible.

The Arizona Court of Appeals, Division One, ruled on Sept. 30, 2026, with coverage on Thursday, Oct. 1, ABC15, FOX 10 Phoenix, and Reuters reported. The court affirmed Gabriel Paul Horcasitas's manslaughter conviction in the 2021 Chandler road-rage shooting that killed Christopher Pelkey, vacated the 10.5-year prison sentence, and sent the case back to Superior Court for resentencing. A new sentencing date had not been set in the Thursday coverage.

At the original sentencing, the victim's sister introduced an AI-generated video depicting Pelkey speaking about forgiveness. The sentencing judge said he loved the AI video and referenced the forgiveness theme. The sentence was longer than the nine years prosecutors requested. The appeals court drew a line between real footage of the victim, which it allowed, and AI-generated speech that put words in the victim's mouth that he never said, which it said failed reliability and due-process minimums.

Defense attorney Jason Lamm told reporters that courts are skeptical of AI in legal proceedings. That comment is counsel's statement to the press. It is not a finding in the opinion. The conviction stands, and the prison term does not, until a new sentence is imposed. All defendants are presumed innocent until proven guilty in a court of law.
