What started the Palisades Fire, and why did the LA arson trial fall apart? This Howtown episode investigates the deadly Pacific Palisades wildfire, the smaller New Year’s Eve Lachman Fire, and the federal arson case against Jonathan Rinderknecht. Prosecutors argued that the Lachman Fire became a hidden holdover fire, smoldering in roots and dense vegetation before reigniting during Santa Ana winds and becoming the catastrophic Palisades Fire. We examine how ATF fire investigators determine fire origin and cause using wildfire forensics, burn patterns, fire behavior, wind direction, topography, fuel, surveillance camera footage, ALERTCalifornia cameras, cell phone location data, ignition source testing, and lab experiments. The episode also looks at competing theories in the Palisades Fire investigation, including fireworks, cigarette ignition, open flame, accidental fire, intentional arson, smoldering roots, and reignition. At trial, prosecutors pointed to Rinderknecht’s location, behavior, searches, messages, 911 calls, and alleged motive, while the defense argued there was no direct evidence, no smoking gun, no recovered ignition source, and serious uncertainty in the wildfire investigation. The LA arson trial ended with a deadlocked jury, a mistrial, and a 10–2 split, raising questions about reasonable doubt, negative corpus, forensic science, ATF methods, LAFD response, the Skull Rock trailhead, the Lachman Fire origin, and why proving wildfire arson is so difficult after the evidence has burned away.
