AI Evidence in Court: An Arizona Sentencing Shows the Stakes
Source: ABC News, October 6, 2026
As reported by ABC News, a three-judge panel of the Arizona Court of Appeals upheld a man’s manslaughter conviction in a road-rage shooting but threw out his prison sentence. During the sentencing hearing, the judge had been shown an AI-generated video that recreated the victim’s likeness and voice. According to ABC, the video was created by a member of the victim’s family, and in it, the AI likeness spoke about forgiveness.
The appeals panel said the video “crossed” a line. As quoted by ABC, the panel found that the judge’s consideration of the video so prejudiced the defendant “as to render the sentencing procedure fundamentally unfair.” The case now returns to the lower court for a new sentencing, and ABC reports that no date has been set.
A family’s wish to have a loved one’s voice heard is easy to understand, and nothing here is a criticism of them. The ruling is about how a court handles a new kind of material, not about the people who made it. (For a broader look at these issues, see our page on AI crimes and the law.)
AI Is Already in the Courtroom
Artificial intelligence or superintelligence is now part of daily life for hundreds of millions of people, and it is showing up in courtrooms around the country. Attorneys are using it. Litigants are using it. And some people are using it in creative ways to build evidence or presentations that otherwise would be impossible: a person appearing to say words they never recorded, or a scene that no camera ever captured.
In my view, AI evidence in court can have a significant impact on the criminal justice system as a whole. A tool that can produce something this lifelike, this quickly, changes what a judge or jury may be asked to look at.
AI Can Cut Both Ways at Sentencing
When a court decides on a sentence, it weighs aggravating factors, which can point toward a harsher outcome, and mitigating factors, which can point toward a lighter one. AI-generated material could be offered on either side.
One side might present something meant to convey the depth of a loss. The other might present something meant to show who a defendant is, or who they could become. Either way, the same question follows: is the court looking at a record of something that actually happened, or at someone’s interpretation, rendered convincingly by software?
ABC quoted the Arizona panel as saying the video “erases the interpretive distance” between what the family believed the victim would have said and the victim’s own words. That idea reaches well beyond one case.
What Courts and Litigants Need to Understand
It is important that courts, lawyers, and the people involved in a case understand artificial intelligence, and how the rules of criminal procedure and the rules of evidence may apply to it at every stage:
- Before trial. Questions about AI material can come up early: what exists, where it came from, and whether it should be examined or challenged before anyone relies on it.
- At trial. Is the item authentic? How was it made, and who made it? Was it edited or generated? Does it fairly represent something real, or could it mislead a jury?
- At sentencing. A judge may hear a wider range of material at sentencing than a jury hears at trial, but fairness still matters. As the Arizona ruling shows, what a judge sees and hears there can carry real weight.
So can AI evidence be used in court? There’s no single answer that fits every case. Much depends on the facts, the court, and the state.
Why This Matters if You’re Facing Charges
If you are under investigation or facing charges, AI may already touch your case. It might be in the evidence the government gathers, in material someone else creates, or in what is presented about you at a hearing. AI-generated images, audio, and video can look and sound real, which is exactly why they deserve careful scrutiny. (We’ve written about AI-generated images and deepfakes, the law around AI image generators, and how police get AI chats, images, and account records. Our Florida site recently looked at a Lee County arrest involving AI chats.)
I believe courts and lawyers are only at the beginning of working through these questions. The people whose cases come first will help shape the answers.
