On January 23, 2023, a mass shooting at two agricultural sites in Half Moon Bay, California, left seven people dead, including 73-year-old Zhishen Liu of San Francisco. The attacks occurred at California Terra Garden (formerly Mountain Mushroom Farm) and Concord Farms. Authorities say the assailant, 66-year-old employee Chunli Zhao, first opened fire at California Terra Garden, killing four coworkers and critically injuring another, then drove about two miles to Concord Farms and fatally shot three former colleagues.

Zhao was located in his vehicle in a sheriff’s substation parking lot and arrested without incident; a semi-automatic handgun was found in the vehicle. He was charged with seven counts of first-degree murder with special circumstances and one count of attempted first-degree murder and has pleaded not guilty. The victims included Marciano Martinez Jimenez, Zhishen Liu, Aixiang Zhang, Jingzhi Lu, Qizhong Cheng, Yetao Bing and Jose Romero Perez.

The shootings prompted vigils and renewed attention to farmworker living and working conditions after investigations found substandard housing and payroll violations at the two farms, and the owners agreed to pay back wages, damages and civil penalties. If anyone knew Zhishen Liu or has information about him or the events that day, please share what you can.
