Seven people killed in latest U.S mass shooting

Seven people were killed in a mass shooting at two locations in the coastal northern California city of Half Moon Bay on Monday.

The San Mateo County Sheriff's Office on Twitter reported a shooting incident with multiple victims and said a suspect was in custody.

Half Moon Bay is about 50 km south of San Francisco.

Investigators had peacefully taken a 67-year-old man into custody about two hours after the incident, as a deputy spotted the suspect's car in a parking lot of a San Mateo County Sheriff's Department substation, the San Francisco Chronicle reported, citing a sheriff's department statement.

The weapon was found in his car, the report said.

Deputies responding to a call found four people dead and a fifth victim wounded at the first location in Half Moon Bay, then found three more dead at another place nearby, the Chronicle reported.

One of the locations was a mushroom farm.

The shooting took place as the city of Monterey Park in Los Angeles County, about 640 km to the south, was still roiling from a mass shooting on Saturday that killed 11 people.
