An Oroville man known for his past arson conviction faced new charges in Butte County Superior Court on Tuesday. Alfonso Pasillas of Oroville was arraigned on a new arson charge after allegedly starting a fire with a flare gun. Butte County District Attorney Mike Ramsey said that on August 2, Pasillas caused a grass fire by firing flares from a flare gun. One of these flares landed in dry grass on La Mirada Avenue in rural east Oroville, igniting a blaze. The Butte County District Attorney's Office says that Pasillas was previously convicted of attempted arson in early 2024. Pasillas is scheduled to return to court on August 7, 2025, for a plea entry and preliminary hearing setting. If convicted, Pasillas could face up to 12 years in state prison.
