Official: 7 killed in California community; suspect arrested

HALF MOON BAY, Calif. (AP) - Seven people were killed in two related shootings Monday  in a coastal community south of San Francisco, and officials say a suspect has been arrested.

The San Mateo County Sheriff's office says 67-year-old Chunli Zhao is in custody.

Authorities say four people were found dead and one critically wounded from gunshots mid-afternoon. Then three others were found dead at a business several miles away.

The connection between the locations is unclear but the sheriff's office says both are agricultural businesses.

The shootings occurred on the outskirts of Half Moon Bay, a coastal city south of San Francisco. A motive for the shootings wasn't immediately known.
