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 cause of the fire, which burned 78 acres, remained under investigation, according to Cal Fire, the state firefighting agency.

Authorities in Northern California have found the bodies of all seven people missing since an explosion last week at a fireworks warehouse that caused a wildfire and shook a tiny farming community.
