The Camp Fire has destroyed 6,453 homes and 260 commercial buildings in the area around Paradise, making it the most destructive to buildings in state history, surpassing the Tubbs Fire, which destroyed 5,636 structures in Napa and Sonoma counties past year.
The fire has left nine people dead, the Butte County Sheriff's Office said Friday. Of those killed, five people were found in or near a vehicle and the other four were found in or outside a home.
