Gabriel Paul Horcasitas, 55, was convicted of shooting and killing 37-year-old Christopher Pelkey during a confrontation at a red light in 2021. At his sentencing hearing last year, Pelkey's sister Stacey Wales presented an AI-generated video that used voice recordings, photographs and videos to recreate her brother. In the clip, an AI version of Pelkey wearing a grey baseball cap told Horcasitas: "To Gabriel Horcasitas, the man who shot me, it is a shame we encountered each other that day in those circumstances. In another life, we probably could have been friends." The video went on to express forgiveness.
Judge Todd Lang, who presided over the original sentencing, welcomed the video, saying: "I loved that AI, thank you for that. As angry as you are, as justifiably angry as the family is, I heard the forgiveness. I feel that that was genuine."
But Horcasitas's legal team appealed, arguing that the video was improper. The Arizona Court of Appeals agreed, ruling on Wednesday that the AI clip "crossed that line." The court wrote: "Rather than document an event or recording a particular moment, the AI video presents a depiction of the victim and his thoughts created from the imaginings of the victim's sister." The panel ordered that Horcasitas be resentenced.
The case highlights a growing debate over the admissibility of AI-generated evidence, particularly in emotional contexts like victim impact statements. Horcasitas's lawyer declined to comment, and an attorney for the victims did not respond to a request for comment.
