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 Sacramento County and Yolo County Sheriff's Offices are at a San Francisco home after a deadly fireworks warehouse explosion in Esparto.

The explosion, which left seven people missing, started a wildfire and forced some cities and counties to cancel or postpone Fourth of July fireworks shows.
