Seven people have lost their lives due to being killed in a mass shooting that spanned two separate scenes in Half Moon Bay Monday afternoon, according to the San Mateo County Sheriff's Office.
Four victims with gunshot wounds were found dead at a nursery along the 12700 block of San Mateo Road (Highway 92), the sheriff's office said.
Another shooting victim was taken to Stanford Medical Center with life-threatening injuries.
Shortly after that discovery, three more victims were found dead at another nursery near by.
Authorities identified the suspect as 67-year-old Half Moon Bay resident Chunli Zhao. He was taken into custody without incident, after he was found in his vehicle in the parking lot of the sheriff's office substation in Half Moon Bay, the sheriff's office said.
A semi-automatic handgun was found in his car.
Zhao shot three of the victims in the trailers where they lived next to the field where they worked and then gunned down two others in the field itself, officials said.
"This is truly a heartbreaking incident in our community," San Mateo County Supervisor Ray Mueller said.
According to NBC Bay Area, authorities believe Zhao acted alone and that a motive for the shooting wasn't immediately known.
The victims, a mix of Asian and Hispanic adults, are believed to be workers on the properties, San Mateo County Sheriff Christina Corpus said.
"This is a devastating tragedy for this community and the families touched by this unspeakable act of violence," Corpus said.
The shootings in Half Moon Bay is another massive shooting that hit Californian’s this week.
"This kind of shooting is horrific," Corpus said. "It's a tragedy that we hear about far too often, but today it's hit home here in San Mateo County."
California Gov. Gavin Newsom said he was meeting with victims of the Monterey Park shooting when he learned about the mass shooting in Half Moon Bay.
"Tragedy upon tragedy," he said in a tweet.
The shooter had some bad blood history with a co-worker as he had threaten the man with cutting his head open with a knife and trying to suffocate the man a decade ago at another Bay Area job, according to court records obtained by The Chronicle
Noted in the SF Chronicle, back in 2013, Jingjiu Wang filed for a temporary restraining order against Zhao, telling a judge his roommate and co-worker at a San Jose restaurant had physically assaulted him and made death threats days earlier. A judge granted the order, which is no longer in effect.
