An Uber passenger who rode with the man accused of igniting the deadliest Los Angeles wildfire in a generation told jurors the driver spent the trip complaining about women, railing against the wealthy, and projecting what the passenger called "incel energy" just hours before the fire allegedly started.
Brennan White's testimony, delivered during the federal arson trial of 29-year-old Jonathan Rinderknecht, offered the jury a window into the accused man's state of mind on the night prosecutors say he deliberately set a brushfire that smoldered underground for six days before erupting into the catastrophic Palisades wildfire. That blaze killed 12 people, destroyed nearly 7,000 structures, scorched more than 23,000 acres, and caused over $150 million in damages.
White, who was a passenger in Rinderknecht's car on New Year's Eve 2024, told the court that Rinderknecht ranted about humanity crumbling and the lack of good women in the region. The testimony painted a picture of a brooding, resentful driver who made at least one woman in the car visibly uncomfortable.
The word "incel," short for "involuntary celibate," describes a subculture of men who harbor deep grievances over perceived romantic rejection. White used the term to characterize the overall tone of Rinderknecht's behavior that night.
Former federal prosecutor Neama Rahmani, commenting on the trial's strategy, explained why that characterization matters to the government's case. As Breitbart reported, Rahmani said:
"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."
Prosecutors do not need to prove motive to secure a conviction on the federal arson charges. But establishing a pattern of resentment and antisocial fixation helps them explain why a man with no obvious connection to Pacific Palisades would drive to a hiking trail after midnight and allegedly light a fire.
The testimony about Rinderknecht's demeanor tracks with what prosecutors laid out in pre-trial filings. Court documents revealed that when investigators asked Rinderknecht why someone might commit arson in Pacific Palisades, he gave a pointed answer.
"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."
Prosecutors also allege Rinderknecht fixated on Luigi Mangione, the man charged in the killing of UnitedHealthcare CEO Brian Thompson, in the weeks before the fire. The government claims Rinderknecht drew a comparison between potential arson and the Mangione murder, framing both as acts of class rebellion. CLN has previously covered the suspect's alleged rants about Mangione and class resentment as revealed in court filings.
That ideological thread runs through the prosecution's entire theory: a man stewing in grievance, consuming radical ideas online, and finally acting on them in the most destructive way possible.
Physical testimony is only one layer of the government's case. National Review reported that digital evidence recovered from Rinderknecht's devices includes ChatGPT search history showing prompts for images of a burning dystopian city, along with iPhone videos that investigators say corroborate the allegation that the fire was set "intentionally and maliciously."
Acting U.S. Attorney Bill Essayli framed the case in stark terms when Rinderknecht was first arrested:
"The complaint alleges that a single person's recklessness caused one of the worst fires Los Angeles has ever seen, resulting in death and widespread destruction in Pacific Palisades."
Kenny Cooper, ATF Special Agent in Charge, was blunter: "Evil people do evil things."
Rinderknecht faces three federal arson-related charges: destruction of property by means of fire, arson affecting property used in interstate commerce, and timber set afire. A conviction could bring up to 45 years in prison. He has pleaded not guilty to all counts. As CLN reported when the trial opened, the case hinges on whether prosecutors can connect the New Year's Day fire to the larger inferno that followed.
Prosecutors allege Rinderknecht ignited what became known as the Lachman fire near a hiking trail at 12:12 a.m. on New Year's Day 2025, moments after dropping off Uber passengers. The fire was reported and responded to by the Los Angeles Fire Department. But court documents indicate the blaze was not fully extinguished. It continued smoldering underground in root systems for six days before flaring back to life on January 7 as the Palisades wildfire.
That six-day gap sits at the heart of the defense strategy. Rinderknecht's attorney, Steve Haney, has argued his client is being used as a fall guy for institutional failures. As AP News reported, Haney told the court:
"Rinderknecht is being used as a scapegoat for the Los Angeles Fire Department's failure to fully extinguish the earlier blaze."
But Judge Anne Hwang dealt the defense a significant blow in pretrial rulings. She barred Haney from introducing fire department depositions at trial, including testimony that the New Year's Day blaze was visibly smoldering when first responders left the scene. The ruling effectively prevents the defense from putting LAFD negligence on trial alongside their client.
The judge's restrictions forced the defense to tighten its focus. Haney acknowledged the shift in comments reported by the New York Post:
"The judge has put some restrictions on us with respect to arguing the negligence of the fire department. That would lead into Karen Bass having some kind of role here in terms of testimony. So our focus will be a little narrower, on the fact that [Rinderknecht] didn't start the fire on January 1."
Mayor Karen Bass will not testify, despite the defense's earlier interest in questioning her about the city's fire response. The defense now centers its case on a flat denial: Rinderknecht did not start the Lachman fire at all.
Hwang also excluded AI-generated images of a burning city that prosecutors had sought to introduce, ruling they could not be presented to the jury. That cut both ways, removing a piece of dramatic visual evidence from the government's presentation while keeping the trial focused on direct proof of ignition. CLN previously covered how a prosecution fire expert rejected the defense's theory that fireworks caused the blaze.
The government's case rests on two pillars: physical evidence tying Rinderknecht to the ignition point, and a psychological portrait of a man spiraling into resentment. The Uber passenger testimony serves the second pillar. White's account of a driver who couldn't stop talking about societal collapse and the absence of worthy women gives prosecutors a narrative frame for the digital evidence and the defendant's own statements to investigators.
Rinderknecht, a Florida resident who was working as an Uber driver in the Los Angeles area at the time, had no known prior connection to Pacific Palisades. Prosecutors argue that makes the resentment motive all the more telling: he allegedly targeted a wealthy enclave precisely because of what it represented to him.
Just The News reported that jury selection began in June 2026, with the trial now underway. The defense maintains that Rinderknecht "denies he willfully and maliciously set" the fire that developed into the larger blaze, and therefore cannot be held responsible for the destruction that followed.
Investigators have not publicly confirmed whether any additional suspects or contributing causes remain under review. The trial is expected to continue in the coming weeks. CLN has followed the case closely, including the suspect's alleged online searches about "taking down billionaires" before the deadly blaze.
The central question is deceptively simple: Did Jonathan Rinderknecht light a fire on New Year's Day? If yes, federal law holds him responsible for the foreseeable consequences of that act, even if the fire department failed to finish the job of putting it out. The judge's ruling blocking LAFD negligence evidence makes that chain of causation harder for the defense to break.
Twelve people are dead. Nearly 7,000 structures are gone. And a jury in a federal courtroom is now weighing whether all of it traces back to one man's match and one man's grudge against a world he felt had left him behind.
When grievance curdles into destruction on this scale, the justice system owes the dead more than a scapegoat debate. It owes them a verdict built on facts.
