SAN FRANCISCO—A farmworker charged with killing seven people last year in back-to-back shootings at two Northern California mushroom farms was indicted by a grand jury in an effort by prosecutors to move the case along, authorities said.
Chunli Zhao was in court Tuesday to be arraigned on seven counts of first-degree murder and one count of attempted first-degree murder, but his arraignment was continued until Feb. 29, San Mateo County District Attorney Steve Wagstaffe said in an email.
