Investigators suspect it was started by sparks from a power tool being used to clear brush. The fire destroyed 80 homes, burned 8,700 acres, and, at its height, forced 30,000 people to evacuate.
Fire officials announced full containment on Monday. Also on Monday, Ventura County firefighter Robert Lopez was released from the Grossman Burn Center in Sherman Oaks, where he was being treated for second- and third-degree burns he suffered to his face and arms while protecting a home in the early days of the fire.
Doctors say he will make a full recovery. Two other firefighters were released from the burn center earlier. In all 28 firefighters were injured battling the blaze.
