Oates declined to provide details of the four slain workers. He did not know how long Zhao worked there, adding that he was one of 35 employees who had stayed on when ownership changed. But California Terra Garden took over the business last year, company spokesperson David Oates said.
The sheriff’s office identified the first shooting location as Mountain Mushroom Farm. Wang could not be immediately reached, the Chronicle reported. The two were roommates and worked at a restaurant at the time, and the man, identified as Jingjiu Wang, filed a temporary restraining order against Zhao that was granted but is no longer in effect.
In 2013 Zhao was accused of threatening to split a coworker’s head open with a knife and separately tried to suffocate the man with a pillow, the Chronicle reported, based on court documents. But would not have been Zhao’s first fit of workplace rage, the San Francisco Chronicle reported.
