Six more homicide detectives have been added to the case, as investigators try to find out who set a giant wildfire outside Los Angeles.
Police are also reviewing dozens of tips from the public.
The fire has ravaged a 250-square-mile stretch of national forest, and killed two firefighters. It destroyed 82 homes.
The fire's single point of origin has been traced to an area near an oak tree below a curvy mountain road. Investigators are no longer at the crime scene, but the highway remains closed and police tape still surrounds the roadside turnout near where the fire started.
A reward of $150,000 is being offered.
