Justin Wayne Halstenberg, a 34-year-old delivery driver from Norco, California, has pleaded not guilty to starting the Line Fire, which has scorched over 38,000 acres and forced the evacuation of thousands of homes. Prosecutors allege that Halstenberg attempted to ignite three fires on September 5, 2024; the first two were extinguished by a firefighter and a good Samaritan, while the third grew into the Line Fire. Halstenberg faces multiple arson charges, including aggravated arson and arson causing great bodily injury. His mother defends him, claiming he is not an arsonist. The fire has damaged numerous properties, injured several firefighters, and is partially contained. Halstenberg remains in custody without bail, with his next court appearance scheduled for Monday.
