Early on January 1, 2025, as everyone else in Los Angeles was still ringing in the new year, Jonathan Rinderknecht hiked into the Santa Monica Mountains and, with his cigarette lighter, allegedly set some paper or brush or both alight. The flames spread and, prosecutors say, became the Lachman fire, which would in turn become the much bigger Palisades fire—the most disastrous blaze in the city’s history.

Rinderknecht was an Uber driver, and he had been “agitated and angry” earlier that night, according to two girls he’d driven around. About what, they couldn’t be sure. It didn’t really matter.
