Arizona Appeals Court Reverses Sentence After AI‑Generated Victim Video Played

By New York Times

An Arizona appeals court on Wednesday overturned the prison sentence of Gabriel Horcasitas, 55, who had been convicted of manslaughter in the 2021 road‑rage shooting death of Christopher Pelkey, 37. The three‑judge panel upheld the conviction but ruled that Horcasitas must be resentenced because the original sentencing judge made a “fundamental error” by allowing and relying on an artificial‑intelligence video that generated a likeness of Pelkey’s voice and appearance. The court found the video did not “reflect actual events” and presented statements as if they were coming directly from the victim.

The AI video was used during the sentencing hearing last year, alongside victim‑impact statements from Pelkey’s family and friends. Pelkey’s older sister, Stacey Wales, presented the video, which showed a digital recreation of Pelkey addressing Horcasitas and the court, saying, “I believe in forgiveness and in God who forgives,” and “This here is a true representation of who I was.” The sentencing judge, Todd F. Lang of Maricopa County Superior Court, praised the video, calling it “genuine” and noting that the victim was allowed to “speak from his heart.” He then imposed the maximum sentence of 10½ years, more than the nine years prosecutors had sought.

The appeals court noted that the use of the AI‑generated video raised a novel legal issue and that no prior Arizona case had addressed the admissibility of such a depiction of a victim during sentencing. It held that a victim’s right to speak cannot override a defendant’s right to be sentenced based on accurate and reliable information. The judges wrote that the video “erases the interpretive distance between the family’s belief about what the victim would have said and the victim’s own voice and opinions,” making the sentencing procedure fundamentally unfair.

Wales had spent two years preparing her own victim‑impact statement and said she felt a critical element was missing. She explained that she and her husband, who work with AI for corporate presentations, used a YouTube clip of Pelkey speaking after treatment for post‑traumatic stress disorder and a funeral poster to create the digital likeness. She wrote the script that was read by the AI representation.

On Nov. 13, 2021, Pelkey was stopped at a red light in Chandler, a Phoenix suburb, when Horcasitas pulled up behind him and honked. Pelkey left his vehicle and approached Horcasitas’s car, gesturing as if to say, “What the heck?” Horcasitas then fatally shot Pelkey in the chest. The case will be returned to Maricopa County Superior Court for a new sentencing hearing, without the AI‑generated video of Pelkey giving his statement.
