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. 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. 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.
