A fire completely destroyed a mobile home, and spread to several outbuildings in Corning.
The fire started around 4 a.m. on Thursday morning at a junk yard near Highway 99 West and Chase Avenue.
Firefighters say the mobile home was fully involved when they arrived, and the flames were so intense that it took them over an hour to contain the fire.
It also took them several minutes to get water to the fire because there was no water source in the area.
The fire spread to sheds and cars, as well as several other items on the property.
CALFIRE officials say waste materials inside the mobile home have created toxic smoke that is dangerous for the firefighters.
Investigators are not ruling out arson at this point, saying the source of the fire does seem suspicious.
