Authorities on Wednesday named a suspect in connection to the deadly, devastating Palisades fire in Los Angeles County.

The suspect has been identified as Jonathan Rinderknecht, 29, of Florida.

Kenny Cooper, a special FBI agent in Los Angeles, said the blaze, the most destructive in Los Angeles history, was an "incendiary fire" and the "subject arrested started it."

Authorities said Rinderknecht, an Uber driver, was "charged with the Palisades Fire that started January 1."

They also said evidence includes content on his phone and of him returning to the fire after he set it to watch firefighters battle the blaze. 

U.S. Attorney Bill Essayli said authorities also collected from Rindderknecht's digital devices an image he generated on ChatGPT depicting a burning city.

The blaze killed 12 people and destroyed over 6,000 homes and buildings in the Pacific Palisades and Malibu. It was a rekindling fire that Rinderknecht allegedly set on New Year's Eve near a popular hiking area, federal investigators alleged.
