In a landmark decision, an Arizona court of appeals ordered that the sentence of Gabriel Paul Horcasitas be set aside when it was found that an AI‑generated video of the victim, Christopher Pelkey, had been improperly shown to the jury.
Pelkey, 37, was shot to death by Horcasitas at a red light in 2021. After a jury conviction, Horcasitas received a 10‑year sentence. However, the prosecution’s lawyers had requested that a digitally rendered recitation of Pelkey’s thoughts be streamed during the sentencing hearing, a request that the trial judge affirmed.
The appellate court explained that the clip – created from Pelkey’s family’s voice recordings, photographs and video – presented a reenacted version of the victim’s mind, which the court warned was beyond the scope of admissible evidence. In its ruling, the court noted: “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.”
Horcasitas’ attorney, Kristen Reller, declined to comment, while supporters of the use of AI in the courtroom said it had provided a powerful moment of empathy. Judge Todd Lang had praised the AI’s ‘genuine’ forgiveness when it first appeared in 2025, but the appeals court’s decision signals a cautious approach to emerging technology in the justice system.
The new sentencing hearing will now decide whether Horcasitas will retain the 10‑year term, face a longer sentence, or adhere to a reduced timeframe, depending on what evidence the new proceedings are deemed admissible to present.
