An Arizona man’s 10-year manslaughter sentence has been tossed in a case where a video generated by artificial intelligence portrayed the deceased victim addressing a judge before the punishment was imposed.
asserted
punishment → toss → judge
In a decision released Wednesday, the Arizona Court of Appeals concluded Gabriel Paul Horcasitas must be resentenced in the 2021 shooting death of Christopher Pelkey because the AI video wasn’t reliable.
asserted
video → release → Pelkey
The court found the video crossed the line, saying it didn’t reflect actual events and presented statements made in the footage as coming directly from the victim.
“
asserted
it → find → victim
Indeed, 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,” the three-judge panel wrote.
asserted
panel → document → sister
Jessica Gattuso, an attorney who represented victims in the case, and Kristen Reller, Horcasitas’ lawyer, declined to comment Thursday on the decision.
asserted
who → represent → decision
Reller had argued Superior Court Judge Todd Lang violated due process protections by relying on AI evidence.
asserted
Lang → argue → evidence
Gattuso and prosecutors told the appeals court that the lower-court judge didn’t err, saying the footage was an accurate representation of Pelkey’s character.
asserted
footage → tell → character
In what’s believed to be a first in U.S. courts, Pelkey’s family used AI to create a video of his likeness to give him a voice.
asserted
family → believe → voice
Pelkey’s sister, Stacey Wales, raised the idea of her brother speaking for himself after struggling to figure out what he would say.
asserted
he → raise → what
Wales expected an appeal on the sentence and was disappointed the AI video was cited as the reason, saying her only goal was to humanize her brother for the judge.
asserted
goal → expect → judge
“It feels unfair because there is a convicted murderer sitting in prison that has blankets and walls of protection around their rights.
asserted
that → feel → rights
Where are the rights for the victim?” Wales said.
asserted
Wales → say → victim
A victim appeals lawyer has told the family that using AI again could result in another appeal.
uncertain
using → tell → appeal
“We will continue to let his voice be heard in whatever allowable medium we can convey that through the court system,” Wales said.
asserted
Wales → continue → system
The AI-generated victim impact statement was played during a May 2025 sentencing hearing after nine of Pelkey’s family members and friends stood before the judge describing how emotionally devastated they were by his killing.
uncertain
they → generate → killing
Authorities say Horcasitas, 55, fatally shot Pelkey, 37, during a November 2021 road rage encounter at a stoplight in Chandler, a suburb of Phoenix.
asserted
Horcasitas → say → Phoenix
Pelkey, who was unarmed, was shot after getting out of his truck and walking toward Horcasitas’ vehicle.
asserted
who → shoot → vehicle
Horcasitas was convicted of manslaughter in Pelkey’s death and endangerment for a gunshot that struck another vehicle at the intersection during the encounter.
asserted
that → convict → encounter
The AI rendering of Pelkey said he wished he could still be with his friends and family, voiced a belief in forgiveness and said it was a shame Horcasitas had encountered him because “in another life, we probably could have been friends.”
uncertain
we → say → life
The video didn’t request a specific prison sentence.
asserted
video → request → sentence
Horcasitas’ appellate lawyer argued her client had no meaningful opportunity to rebut material in the AI-generated video.
asserted
client → argue → video
It’s not clear if attorneys or the court were aware in advance that an AI-generated video would be used.
asserted
video → ’ → advance
But attorneys representing Pelkey’s family said in court records that Arizona law does not require victims to disclose statements they plan to make in court to prosecutors, defense attorneys or the judge — and that victims can exercise their rights by speaking before the court or submitting statements that are written or recorded on audio or video.
asserted
that → represent → audio
In a statement Thursday, the Maricopa County Attorney’s Office said its prosecutors knew the victim’s family would address the court during sentencing but weren’t aware of the nature of it.
asserted
family → say → it
While the use of AI within the court system is expanding, it’s typically been reserved for administrative tasks, legal research and case preparation.
asserted
it → expand → tasks
In Arizona, it’s helped inform the public of rulings in significant cases.
asserted
it → help → cases
But using AI to generate victim impact statements marks a new tool for sharing information with the court outside the evidentiary phases.
asserted
using → use → phases
Reller told the appeals court that the video doesn’t disclose who wrote the words used by the AI version of Pelkey and wasn’t backed up with evidence establishing that its contents accurately reflected Pelkey’s views.
asserted
contents → tell → views
It also had an “undue emotional weight” and conveyed an authenticity that wouldn’t have been there had a family member read the same words aloud, Reller said.
asserted
Reller → have → words
Horcasitas’ lawyer contended the judge weighed the statements made in the AI-generated video when deciding on a sentence, but prosecutors argued Lang didn’t consider the footage when issuing the punishment.
asserted
Lang → contend → punishment
Shortly before delivering the sentence, the judge commented that he “loved that AI” but didn’t say from the bench whether the video factored into his decision.
asserted
video → deliver → decision
Lang said he felt Pelkey’s “obvious forgiveness of Mr. Horcasitas reflects the character I heard about today.”
asserted
I → say → character
The family’s lawyers say the judge was already inundated with relevant information from Pelkey’s family and friends before the AI video was played — and that nothing in the video was inflammatory.
asserted
nothing → say → video
They also said Pelkey’s previous attorney didn’t object to the AI video.
asserted
attorney → say → video
