A man accused of sparking the New Year’s Day fire that helped fuel the deadly Palisades inferno allegedly displayed “incel energy,” according to a passenger who rode in his Uber.
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 connection with the Palisades Fire in January 2025. He’s currently facing trial in California. Los Angeles resident Brennan White testified Friday that when he rode in Rinderknecht’s Uber with his fiancee on New Year’s Day in 2025, that the suspect gave off “incel energy.”
White said that Rinderknecht was driving erratically and wouldn’t stop talking about how humanity was crumbling, talking about how there aren’t any good women in the region.
The witness told the Los Angeles Police Department that Rinderknecht gave off “incel energy,” saying it’s a slang term for someone who’s a loner or more isolated.

White, who was drinking that night, said he made small talk with Rinderknecht for the first three to five minutes of the ride, then the driver started ranting. He said that Rinderknecht was violent with his words but didn’t ask to be let out of the Uber because he felt it was better not to say anything.

Former federal prosecutor Neama Rahmani told Fox News Digital this may be one of the most “memorable” moments of Rinderknecht’s trial and added that prosecutors had a specific reason for calling White to testify.
“An incel is someone that is unable to have or maintain a relationship and is celibate involuntarily. So someone that is a loner, someone who is strange, someone like that is more likely to be an arsonist, is more likely to be a mass shooter. So by painting him in this way, I think it does help the prosecution’s case,” Rahmani said. “The question is, is this unfair character assassination? Because Rinderknecht isn’t charged with being a strange guy, he’s charged with an arsonist. And potentially this gives the defense another argument on appeal if their client is convicted.”

In a trial memorandum filed in April, prosecutors said Rinderknecht was apparently obsessed with Luigi Mangione, who is accused of assassinating UnitedHealthcare CEO Brian Thompson.
“In the months leading up to the fire, he had become increasingly angry with his life and society at large,” prosecutors wrote. “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.

“Many of defendant’s Uber passengers on December 31, 2024 and January 1, 2025, described defendant as angry, intense, driving erratically, and ranting about being ‘pissed off at the world’ and Luigi Mangione, capitalism, and vigilantism,” prosecutors added in the court filing.

When investigators asked Rinderknecht on Jan. 24, 2025, why someone might commit arson in the Pacific Palisades, he allegedly responded it would be out of resentment and invoked Mangione.
“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.”
Lena Weissbrot, who considers herself a supporter of Mangione, addressed the connection while speaking to Fox News Digital on Tuesday outside of a scheduled court hearing for the alleged UnitedHealthcare CEO killer.

“I don’t think we can blame these things on Luigi, I think it’s that we have so much wealth inequality in America, that eventually it’s going to boil over, and I think that Luigi was just a temperature check for like…It sort of allowed people a vessel for all of the rage that’s been boiling under the surface here,” she said.
Weissbrot did add she could “never support” the person who started the Palisades Fire, stating she’s from Los Angeles.
