Suspect in Half Moon Bay, California, shooting faces seven murder charges

The suspect in a Monday mass shooting in the San Francisco Bay Area town of Half Moon Bay faces seven counts of murder, among other charges, the San Mateo District Attorney's office announced Wednesday.

Chunli Zhao will also face one count of attempted murder, a special circumstance allegation of multiple murder, and firearm use enhancements for each murder charge, the LA Times reported. 

Zhao first allegedly killed four and injured one more victim at a mushroom farm, before driving to a second farm where he killed three more, the Associated Press reported. Zhao appears to have worked at both farms.

He was detained Monday evening at a sheriff's substation.

Seven were left dead with one more critically injured this week in separate shooting incidents near Half Moon Bay, Calif. The victims were Chinese farm workers, according to City Councilwoman Debbie Ruddock.

The shooting followed a separate violent incident over the weekend that saw a gunman open fire on a Lunar New Year celebration in Monterey Park, California, killing 11 and wounding nine more.
