Trial of Jonathan Rinderknecht, Accused of Sparking the Palisades Fire and 'Fixated' on Luigi Mangione, Begins in Los Angeles
The trial of Jonathan Rinderknecht, the man federal prosecutors say was 'pissed off at the world' before allegedly lighting the Palisades Fire, begins this week in Los Angeles. The case arrives roughly a year and a half after the deadly and historic wildfire claimed a dozen lives and destroyed thousands of homes and businesses.
According to the trial memorandum, Rinderknecht displayed an 'obsession with fire, fire-setting behavior, and a motive for starting the fire' that began as the Lachman Fire on January 1, 2025. Prosecutors allege that blaze smoldered underground for days, then resurfaced on January 7, exploding into the Palisades Fire – one of the most destructive wildfires in California history.
After Rinderknecht's arrest in October 2025, authorities painted a portrait of a man singularly focused on destruction. They said he repeatedly watched a rap video featuring objects being set on fire in the days before the alleged arson. He also used ChatGPT to generate 'dystopian' images of crowds fleeing flames, though a judge later ruled those images cannot be used at trial.
Prosecutors further allege Rinderknecht was 'fixated' on Luigi Mangione, the man charged with killing UnitedHealthcare CEO Brian Thompson in Manhattan roughly a month before the Palisades disaster. Court documents show Rinderknecht searched for Mangione-related news and phrases like 'free Luigi Mangione' and 'lets take down all the billionaires.'
In an emailed statement to CNN, defense attorney Steven Haney argued the government's pretrial narrative is 'woefully slanted' and that Rinderknecht did not commit the crime. 'Many people will look at this case in a much different light when the trial evidence reveals the facts,' Haney wrote.
If convicted, Rinderknecht faces a minimum of five years and a maximum of 45 years in federal prison. Jury selection is scheduled for Monday.
Court documents describe Rinderknecht working as an Uber driver in the Pacific Palisades on December 31, 2024 and January 1, 2025. Prosecutors say he was frustrated by his inability to make plans or find companionship on New Year's Eve. Several passengers later told investigators he was driving erratically and ranting about being 'pissed off at the world.'
Surveillance footage shows Rinderknecht hiking up a nearby trail after dropping off his last passenger, where he recorded video on his phone. He allegedly lit the fire around 12:12 a.m. on New Year's Day, watched it grow, then tried calling 911 multiple times before leaving the area. He later returned to film the firefighting effort.
Rinderknecht's attorneys counter that he did not start the Lachman Fire and prosecutors cannot link him to the Palisades Fire. They note that investigators initially found no connection after obtaining search warrants on potential suspects, only to claim a link eight months later after other leads went cold.
Prosecutors also point to Rinderknecht's rants to passengers about 'Luigi Mangione, capitalism and vigilantism.' Days after Thompson's killing, he searched for Mangione-related news and took a screenshot of an article about Mangione pleading not guilty. When asked by investigators why someone would commit arson in the affluent Pacific Palisades, Rinderknecht reportedly said it would be out of resentment of the rich enjoying their money while 'we're basically being enslaved by them.'
Josh Campbell, CNN senior correspondent and former FBI special agent, said the prosecution's focus on Rinderknecht's alleged fixation with Mangione is a way to draw parallels to a high-profile case where a defendant is accused of payback against wealthy people. 'Although proving a suspect's motive isn't necessary to obtain a conviction, it can be a powerful driver in convincing juries of a suspect's guilt,' Campbell said.
US District Court Judge Anne Hwang excluded key evidence – including those AI-generated images – from trial, ruling them prejudicial. Defense attorney Haney said those images were taken out of context.
The trial memorandum, filed in April, lays out a plan for testimony from ATF agents, fire engineers and experts who will place Rinderknecht at the scene and argue the Palisades Fire was a holdover from the Lachman Fire that continued to burn underground. Fire investigators acknowledge arson trials are rarely open-and-shut cases. Retired ATF investigator Steve Carman said prosecutors face an uphill battle: 'The prosecutor is going to have to convince the jury that the reasoning the ATF agents came up with as to why they believe the fire started in the way it did – that's going to be a big job.'
Separately, another alleged arson case in California has drawn comparisons. In Ontario, a warehouse worker named Chamel Abdulkarim is accused of setting a fire that destroyed a 1.2-million-square-foot warehouse in April 2025, causing an estimated half a billion dollars in damage. Prosecutors say Abdulkarim posted first-person video of the fire and told witnesses 'I just cost these mutherf**kers billions,' equating his act to Mangione's alleged crime. His public defender cited mental illness.
These cases, while unrelated, highlight a broader concern. CNN's Campbell noted that researchers have observed how high-profile incidents can serve as 'a script or template for others to emulate.' He pointed to warning signs: 'Contrary to popular belief, profilers say people don't just one day 'snap' along their pathway to violence but instead will often stew in their real or perceived grievances, providing potential clues to a troubled state of mind.' Prevention, he said, often comes down to family and friends recognizing troubling red flags and intervening early.
