After their initial fire investigation, investigators determined downed power lines have been ruled out as a cause and the fires do not appear to be suspicious in nature.
As the investigation continues, there are indications that the fires may have been started by a vehicle with a mechanical problem or by a vehicle towing a trailer with a low hanging chain.
Anyone with information regarding these fire starts are asked to contact the Fire Prevention Bureau at 530-538-7888 or call the Fire Tip Line at 530-538-6227. Callers can remain anonymous.
