Cal Fire's state fire marshal was leading the investigation at the Inner Richmond home on 2nd Avenue, between Geary Boulevard and Anza Street, a Yolo County spokesperson said.

The address is the former home of Kenneth Chee, the owner and CEO of Devastating Pyrotechnics, who was denied a license by the ATF to acquire or possess fireworks.

One person was killed and four others were injured in a shooting in San Francisco's Bayview neighborhood early Saturday morning.
