Arizona court tosses 10-year sentence over AI victim video

The case began with a November 2021 road rage encounter at a stoplight in Chandler, Arizona, where authorities say Gabriel Paul Horcasitas fatally shot Christopher Pelkey, who was unarmed, after Pelkey got out of his truck. Horcasitas was convicted of manslaughter and endangerment. Before his May 2025 sentencing, Pelkey's family used AI to create a video of his likeness speaking to the judge. Pelkey's sister, Stacey Wales, raised the idea after struggling to figure out what her brother would say; she said her only goal was to humanize him for the judge.

The appeals court found the video did not document an event but presented a depiction of the victim and his thoughts "created from the imaginings of the victim's sister." Horcasitas's lawyer had argued the judge violated due process by relying on AI evidence, while prosecutors and the family's attorney said the footage accurately represented Pelkey's character. The judge had commented shortly before sentencing that he "loved that AI" but did not say from the bench whether the video factored into his decision. It is not clear if attorneys or the court knew in advance that an AI-generated video would be used.

The ruling may hinge on how courts distinguish between AI used for administrative tasks, legal research, and case preparation, and AI used to generate victim statements outside evidentiary phases. For defense attorneys, the decision signals that AI-generated depictions of victims may face heightened scrutiny, while victim advocates may need to weigh the risk of appeals against the goal of humanizing victims in court. The outcome for Horcasitas's resentencing remains undecided, and Wales said the family will continue to let Pelkey's voice be heard in whatever allowable medium they can convey.
