A 67-year-old man was arrested on Monday afternoon after allegedly killing seven farmworkers at two agricultural businesses in the coastal city of Half Moon Bay, the second mass shooting in California in three days. 

Captured on a witness's cell phone, Chunli Zhao was taken into custody by San Mateo County sheriff's detectives after he had parked his SUV in the parking lot of a sheriff’s substation, Sheriff Christina Corpus said.

A semi-automatic handgun was used in the shootings and was located in Zhao's car, authorities said.

One of the crime scenes was located at a mushroom farm in the 12700 block of San Mateo Road, near the Spanish Town shops, where San Mateo County sheriff's deputies responded around 2:22 p.m.

Authorities said four victims were found dead at that scene and a fifth victim was taken to Stanford Medical Center with life-threatening injuries.

A short time later, three more victims were found dead at a second crime scene, at another mushroom farm in the 200 block of Cabrillo Highway, which is about a mile from the first crime scene.

Officials said that Zhao worked at one of those facilities, and that the victims are Latino and Asian employees. 

A motive has not been made clear. 

California is still reeling from an attack on a Lunar New Year celebration in Monterey Park that killed 11 and cast a shadow over an important holiday for many Asian-American communities. Authorities are still seeking a motive for the Saturday shooting.

Alex Garcia Perez said two of his cousins were shooting victims. One was killed and the other is the one who survived and is at the hospital. But he said trying to track down accurate information has been very difficult.
