The mass shooting in Half Moon Bay was the first time seven murders happened in one incident in the history of San Mateo County, the county's district attorney Steve Wagstaffe said.
“This is, by a large amount … the single most victims of homicide in one course of conduct within a short time period,” he said. “This one is in a category that is way beyond anything we’ve ever dealt with. I'm sorry that we have joined the list of counties around this country that have had to deal with this.”
He said the previous incident with the highest number of people murdered at one time in San Mateo County included four people.
Chunli Zhao, 66, is accused of shooting eight people at two locations in Half Moon Bay. According to Wagstaffe, Zhao's gun was a Ruger semiautomatic firearm. Search warrants have been executed but are currently under seal, Wagstaffe said.
Zhao is facing seven counts of murder and one count of attempted murder for his alleged role in the massacre. There are no plans at this time to add any additional charges to the indictment as prosecutors have charged Zhao to the fullest extent of the law, Wagstaffe said.
"The San Mateo County District Attorney's office will do everything in its power working with the sheriff's office to make sure that justice is done here and that the right outcome occurs," he said.
