Mistrial declared for Palisades Fire suspect who allegedly fixated on Luigi Mangione

A federal judge declared a mistrial for the man accused of deliberately igniting the Palisades Fire after jurors failed to reach a unanimous verdict.

Jonathan Rinderknecht was arrested in October 2025 and charged with destruction of property by means of fire and pleaded not guilty after being charged in the Palisades Fire in January 2025. Ten of the California jurors thought Rinderknecht was not guilty, while two thought he was.

“The evidence is strong that Jonathan Rinderknecht is responsible for igniting the fire on January 1, 2025, which eventually became the Palisades fire,” United States Attorney Bill Essayli said in a post on X. “We fully intend to retry this case before a new jury and obtain guilty verdicts on all charged counts.”

On Thursday afternoon, jurors said they had reached a verdict only to come back 30 minutes later to say that they had no verdict.

“Would an additional instruction or the re-reading of any testimony help the jury in their deliberations?” the judge asked.

“There is nothing the court can do to assist the jury in their deliberations. Additional instructions or rereading the testimony would not help in deliberations. Unfortunately, we cannot reach a unanimous verdict,” the jury replied.

In total, estimates say the fire caused $35 billion and $45 billion in damage and led to the deaths of 12 people.

During the trial, behavioral analyst Kevin Kelm testified he believes Rinderknecht’s behavior is similar to someone who is driven by “societal revenge.”

Kelm said that in cases of societal revenge, the suspect typically focuses on personal problems such as finance, relationships, work, lifestyle or anything they’re not capable of dealing with on a daily basis. He said Rinderknecht’s use of ChatGPT was to make a “dystopian image” of the world, where he designed an image representing a barrier between rich people and other individuals who don’t have as much money.

Rinderknecht was partly inspired by Luigi Mangione, who is accused of killing UnitedHealthcare CEO Brian Thompson, prosecutors say.

“In the months leading up to the fire, he had become increasingly angry with his life and society at large,” prosecutors wrote in a court filing. “For example, in the weeks and hours leading up to the fire, defendant fixated on Luigi Mangione, who allegedly murdered the UnitedHealthcare CEO in New York City on December 4, 2024.”

Rinderknecht searched the terms “free LuigiMangione,” “lets take down all the billionaires” and “reddit lets kill all the billionaires” on Dec. 12 and 13, 2024, federal prosecutors said.

“When investigators asked defendant why someone might commit arson in the Pacific Palisades, he responded that it would be out of resentment of the rich enjoying their money as ‘we’re basically being enslaved by them’ and compared such an act of ‘desperation’ to the murder for which Mangione was charged,” prosecutors wrote.

Mangione’s attorney, Karen Friedman Agnifilo, told Fox News Digital in a statement: “As we have stated before in multiple public court filings, Mr. Mangione does not support violent actions and does not condone past or future political violence. These repeated attempts to connect him to unrelated acts or to insinuate that he condones or supports these acts are irresponsible, dangerous and prejudicial.”
