SAN ANDREAS, Calif. (AP) — A dead body was found inside a central California home burned by a wildfire that investigators believe was accidentally started by sparks from a chain saw, authorities said Thursday.

Herbert Wayne Smith, 65, was arrested Wednesday in connection with the blaze that has destroyed seven structures and scorched more than 15 square miles (39 square km) of forest in the Sierra Nevada foothills of Calaveras County.

Smith is suspected of “recklessly causing" the blaze on Monday while “operating equipment capable of producing sparks” without clearing flammable vegetation as required, according to the California Department of Forestry and Fire Protection. Prosecutors will determine whether to file criminal charges.

An apologetic Smith told KCRA-TV that he was using a chain saw to cut some scrap wood when it ignited.

“I’m so sorry for everything that’s happened,” Smith told the news station. “This is going to destroy my life, one way or another."

Investigators will determine whether the fire contributed to the death of the person found in a burned home near the town of Angels Camp, the Calaveras County Sheriff’s Office said.

In eastern Washington state, three major fires continued to burn around the city of Spokane. Officials said Thursday that cooler temperatures and calmer winds have allowed firefighters to make progress against the blazes. No deaths have been reported, though at least 800 buildings have been destroyed.
