ChatGPT helped authorities zero-in on the alleged arsonist who started the deadly Pacific Palisades Fire, which tore through the Los Angeles area in January.

Authorities arrested 29-year-old Jonathan Rinderknecht this week, and ChatGPT provided some of the key evidence in the case. Most notably, authorities pointed out that Rinderknecht had the AI chatbot render a strange, dystopian image that could hint at his potential motivations.

The prompt for ChatGPT read, according to court documents published online by Deadline and other outlets:

“A dystopian painting divided into distinct parts that blend together seamlessly. On the far left, there is a burning forest. Next to it, a crowd of people is running away from the fire, leading to the middle. In the middle, hundreds of thousands of people in poverty are trying to get past a gigantic gate with a big dollar sign on it. On the other side of the gate and the entire wall is a conglomerate of the richest people. They are chilling, watching the world burn down, and watching the people struggle. They are laughing, enjoying themselves, and dancing. The scene is detailed and impactful, highlighting the stark contrast and the direct connection between the different parts of the world.”

The image in question appears in court docs.

The Palisades Fire was incredibly destructive. It killed a dozen people, destroyed more than 6,000 homes, burned 23,000 acres of land, and ultimately led to $150 billion in damage.

Authorities believe the fire was originally sparked by buried embers from the earlier Lachman Fire, which began on New Year’s Day.

Authorities allege that Rinderknecht’s location was pinpointed to a hidden, hilltop trail-clearing where and when the fire began on Jan. 1. Rinderknecht was in that area on New Year’s Eve working as an Uber driver, according to a Justice Department press release. The complaint against him alleges that he delivered passengers around midnight on Dec. 31, then drove to the Skull Rock Trailhead, where the fire began just minutes after midnight.

Phone data allegedly showed he attempted to call 911 around this time but was unsuccessful for a while due to bad reception. ChatGPT was further involved in the case, too. Officials say that around the same time, Rinderknecht asked ChatGPT, “Are you at fault if a fire is lifted [sic] because of your cigarettes?”

Investigators alleged that Rinderknecht “wanted to preserve evidence of himself trying to assist in the suppression of the fire and he wanted to create evidence regarding a more innocent explanation for the cause of the fire.”
