AI-Generated Video Of Dead Arizona Victim Upends Manslaughter Sentence

In a groundbreaking decision, the Arizona Court of Appeals has overturned a 10-year manslaughter sentence for Gabriel Paul Horcasitas. The court determined that the sentencing was invalid due to the unreliability of an artificial intelligence (AI) video that portrayed the deceased victim, Christopher Pelkey, addressing a judge before the punishment was handed down.

The AI-generated video, created by Pelkey's sister, Jessica Gattuso, was deemed untrustworthy as it did not reflect actual events and presented fabricated statements from the victim. The three-judge panel found that the video did not document an event or record a specific moment, but rather depicted Pelkey and his thoughts as imagined by his sister.

Horcasitas' lawyer argued that Superior Court Judge Todd Lang violated due process protections by relying on AI evidence, while Gattuso and prosecutors maintained that the lower-court judge did not err, stating that the footage accurately represented Pelkey's character. This marks the first instance in U.S. courts where AI was used to create a victim impact statement.

Pelkey's family hopes to continue using AI to convey his voice in the court system. Authorities say Horcasitas fatally shot Pelkey, 37, during a road rage incident at a stoplight in Chandler, a Phoenix suburb, in November 2021.
