An Arizona man’s 10-year manslaughter sentence has been overturned by an appeals court because an artificial intelligence video was used during sentencing to portray the deceased victim addressing the judge. The Arizona Court of Appeals ruled Wednesday that Gabriel Paul Horcasitas must be resentenced for the 2021 shooting death of 37-year-old Christopher Pelkey because the AI-generated footage lacked reliability. The three-judge panel determined the video crossed legal boundaries by presenting invented thoughts from the victim’s sister as direct statements from Pelkey. Horcasitas was convicted of manslaughter for fatally shooting Pelkey during a road rage incident at a Chandler intersection in November 2021, along with an endangerment charge for striking another vehicle. In what is believed to be a legal first in the United States, Pelkey’s family utilized AI to synthesize his likeness and voice for a victim impact statement played during the May 2025 sentencing hearing. Stacey Wales, Pelkey’s sister, stated the family combined voice recordings, photos, and videos to recreate her brother so he could seemingly speak for himself, featuring lines about forgiveness and a hypothetical friendship with his killer. Defense attorney Kristen Reller argued that Superior Court Judge Todd Lang violated due process by relying on the AI evidence without an opportunity to rebut it or verify its accuracy, noting the footage carried undue emotional weight. Prosecutors and lawyers representing the victims contended that the lower court judge did not err and that the video accurately reflected Pelkey’s character. Although it remains unclear if the court knew about the AI video beforehand, the Maricopa County Attorney’s Office stated prosecutors were unaware of its nature ahead of time. While Judge Lang remarked during the hearing that he loved the technology, he did not explicitly state whether the footage influenced his final sentencing decision. Legal experts warn that the growing accessibility of deepfake technology could spark more attempts to introduce AI-generated media into courtroom proceedings, creating significant challenges for judges and juries navigating fabricated evidence.
