LOS ANGELES (AP) — Authorities in California charged a 29-year-old man with starting a fire that days later erupted into the most destructive blaze in Los Angeles history, resulting in widespread devastation in the Pacific Palisades neighborhood, federal law enforcement officials announced.

According to U.S. Attorney Bill Essayli, Jonathan Rinderknecht is accused of igniting a fire on New Year’s Day, which smoldered underground before reigniting under high winds. This incident culminated in a catastrophic fire on January 7 that killed 12 individuals and left over 6,000 homes and businesses in ruins.

Rinderknecht reportedly fled from the initial fire scene. Subsequent investigations revealed he returned to the area to watch the fire burn. During questioning by law enforcement, he allegedly provided false information regarding his location, claiming he was at the bottom of the hiking trail during the incident.

Now in custody in Florida, Rinderknecht was scheduled to appear in court on Wednesday. Essayli has yet to provide specifics on how initial fire was ignited, though a criminal complaint suggests it involved a lighter potentially used on vegetation or debris.

This devastating blaze swept through the upscale neighborhood of Pacific Palisades, demolishing luxury homes and erasing blocks of the community. Investigations have confirmed it was deliberately set, ruling out alternative causes like fireworks or faulty power lines.

A parallel blaze, known as the Eaton Fire, broke out the same day, leading to 18 fatalities, although its cause remains undetermined. Following this series of catastrophic events, a review revealed that inefficiencies in emergency response protocols might have delayed alert systems for potential evacuations.

An external report indicated that outdated policies, along with poor communication practices, significantly hindered the responsiveness of local authorities during this critical time.

The repercussions of these events continue to linger, urging a review of community safety and emergency preparedness measures.
