In the tight-nit community of Bonny Doon, are dozens of homes that are among the more than 200 structures destroyed by CZU Lightning Complex Fire.

ABC7 News found an empty, eerie scene along Empire Grade Road in Bonny Doon. Among the gray rubble where homes once stood and the menacing orange flames in the distance, there are homeowners who have risked their lives to stay behind despite orders to evacuate.

Homeowner Gabriel Briton left as flames approached, but returned in an effort to save his home.

"I was there with my brother and two other people holding it back," said Briton.

CAL FIRE said more firefighters are expected to help tackle the CZU Lightning Complex. About 1,600 personnel are currently working on the front lines.
