An Arizona appeals court last week upheld the manslaughter conviction of Gabriel Horcasitas, 55, but overturned his 10½-year prison sentence after the sentencing included a controversial artificial intelligence-generated video of the victim, Christopher Pelkey. The court ruled that the sentencing judge erred by admitting and relying upon the A.I. video, which depicted Pelkey’s likeness and voice conveying a message of forgiveness.
The three-judge panel issued their decision Wednesday, finding that while the conviction related to the 2021 road-rage shooting death in Chandler, Arizona remained valid, Horcasitas must be resentenced without the use of the A.I.-created footage. The court said the video did not reflect actual events and presented statements as if coming directly from Pelkey, thereby blurring the line between the victim’s own voice and the family’s interpretation. This reliance on the artificially generated video was deemed a “fundamental error” that rendered the sentencing process unfair.
The A.I. video had been shown during last year’s sentencing hearing alongside victim-impact statements made by Pelkey’s friends and family. In the video, Pelkey is portrayed addressing the defendant directly, stating, “I believe in forgiveness and in God who forgives,” and asserting, “This here is a true representation of who I was.” The sentencing judge, Todd F. Lang of Maricopa County Superior Court, praised the video during the hearing, describing it as “genuine” and saying that it allowed the victim to “speak from his heart.” Judge Lang subsequently imposed a sentence longer than the nine years sought by prosecutors.
The use of A.I. technology in court has sparked debate among legal experts, with critics cautioning that artificial depictions risk manipulation and could distort the victim-impact process. The appeals court underscored the defendant’s right to sentencing based on reliable and accurate evidence, stressing that a victim’s right to speak should not override this principle.
Pelkey’s sister, Stacey Wales, who prepared the video with assistance from her husband and their business partner, defended its use. Drawing from a YouTube video of Pelkey speaking after PTSD treatment and a funeral poster image, they employed A.I. to recreate his voice and appearance. Wales said the video’s script was written by her and maintained there was no attempt to deceive the court or suggest Pelkey was alive when the video was shown. She also argued that courts have long accepted new media formats to convey victim impact, citing the slow judicial acceptance of photography in the 19th century.
The February 2021 incident stemmed from a road altercation in Chandler, a suburb of Phoenix. Pelkey was stopped at a red light when Horcasitas pulled up behind him and honked. Pelkey exited his vehicle and gestured toward Horcasitas’s car before Horcasitas fatally shot him in the chest.
Following the appeals court ruling, the case will return to Maricopa County Superior Court for resentencing, where the A.I.-generated video will be excluded. None of the involved parties have publicly commented following the decision.
