A man from Santa Rosa has pleaded not guilty to lighting a gas station on fire in Napa County. Darian Preciado is accused of setting the fire in Angwin on June 8th. The 22-year-old was arrested two days later on suspicion of felony arson, and using an accelerant to start the fire. An arrest report says the suspect was an apprentice at the gas station. The station owner has security camera footage that allegedly shows Preciado holding a torch-style lighter inside the garage bay. Authorities say he fired the lighter under a car suspended in the air for a fuel filter replacement. Preciado is out of jail after posting bail and is due back in court on July 12th.
