Arizona court vacates sentence over Judge Todd Lang's AI error
By Adele Rutherford · Reporting from Atlanta ·
The Arizona Court of Appeals properly vacated Gabriel Paul Horcasitas's sentence after Judge Todd Lang relied on an AI video, ruling that synthetic reconstructions violate due process.
Judge Todd Lang of the Maricopa County Superior Court failed the most basic test of a sentencing hearing. He allowed a digital puppet to replace a witness and then admitted he loved the performance. In doing so, he traded the requirements of due process for a moment of synthetic sentiment. The Arizona Court of Appeals was correct to vacate the sentence. To vacate a judgment is to render it void. The appellate court remanded the case, which means it sent the matter back to the lower court for resentencing.
A puppet in the courtroom
The facts of the crime are not in dispute. Gabriel Paul Horcasitas shot and killed Christopher Pelkey on November 13, 2021. A jury rejected the claim of self-defense and convicted Horcasitas of manslaughter and endangerment. In May 2025, Judge Lang imposed a sentence. This was the maximum term.
The sentencing hearing featured a video created by the victim's sister, Stacey Wales. As reported by NBC News and the BBC, the video used AI to recreate Pelkey's likeness and voice. The AI replica told Horcasitas that in another life, they probably could have been friends. It spoke of faith and forgiveness.
Judge Lang did not treat the video as a piece of demonstrative evidence. He treated it as a revelation. He stated, “I loved that AI.” He told the court he felt the video was “genuine.” He noted that while the family demanded the maximum sentence, the AI version of the victim did not. This is where the process broke. A judge's job is to weigh the record, not to fall in love with a simulation.
The gap between evidence and imagination
The state argued the video was consistent with Pelkey’s written beliefs. This is a weak argument. Consistency with a belief is not the same as a recorded statement. The Arizona Court of Appeals saw the distinction. The court wrote that the video “does not reflect actual events.” It was a depiction created from the “imaginings of the victim’s sister.”
This error mirrors the mechanism in Daubert v. Merrell Dow Pharmaceuticals, Inc. In that case, the Supreme Court established that courts must distinguish between reliable evidence based on verifiable methodology and imaginative reconstructions that lack a factual basis. A video of a living person is a record. A generative AI video is a hypothesis. When Judge Lang called the AI “genuine,” he confused a technical approximation with a factual truth.
The appellate court termed this a “fundamental error.” It found that the video crossed the line from permissible impact statements to something unduly prejudicial. The record shows the video impacted the judge's calculus. When a sentencing judge relies on a fabrication, the procedure becomes fundamentally unfair.
The cost of sentimental shortcuts
We have seen this tension before. In State v. Loomis (2014), the court grappled with algorithmic sentencing tools. That case highlighted the risk of using proprietary software to determine a human's fate.
The state's attempt to use AI here was not an innovation in justice. It was an attempt to bypass the silence of the grave. Due process is the constitutional guarantee of fair legal proceedings. It exists to protect the defendant from the whims of the court and the passions of the gallery. By admitting a synthetic voice, Judge Lang invited the gallery to write the sentence.
The Arizona Court of Appeals, which operates in three-judge panels, did the necessary work of cleaning the record. They did not overturn the conviction. They simply insisted that the punishment be based on evidence rather than art.
The law does not require a judge to be cold, but it does require him to be precise. Judge Lang chose a shortcut of the heart over the rules of the court. The result is a vacated sentence and a mandatory do-over. The court has reminded us that a likeness is not a person and a simulation is not a statement. Legitimacy is lost when a judge prefers a digital ghost to the rule of law.
