Seven people were killed by a gunman in Half Moon Bay on Monday afternoon, according to San Mateo County Sheriff’s Deputies. The suspected shooter, Zhao Chunli, is in custody.

Deputies said that at 2:22 p.m. Monday, they were dispatched to the 12700 block of San Mateo Road on Highway 92 in San Mateo County on a report of a shooting with multiple victims.

Upon arrival, deputies located four deceased victims with gunshot wounds. A fifth victim, also suffering from gunshot wounds, was transported to Stanford Medical Center with life-threatening injuries.

Shortly thereafter, three additional deceased victims with gunshot wounds were found at a separate shooting scene in the 2100 block of Cabrillo Highway South.

The motive for the shooting is currently unknown.

The suspect was identified as Zhao, a 67-year-old Half Moon Bay resident.

At 4:40 p.m., Zhao was located in his vehicle in the parking lot of the Sheriff’s Office at Half Moon Bay Police Substation by a Sheriff’s deputy.

Zhao was taken into custody without incident.

At an evening press conference, authorities said that a semi-automatic handgun was located in Zhao's vehicle and that he is believed to have acted alone.
