Hugo Pinell, infamous for his role in the 1970s "San Quentin Six" prison break attempt, was killed Wednesday during a riot at a maximum-security prison outside Folsom, state corrections officials said.
Pinell was among more than half a dozen people injured when an estimated 70 inmates began to fight in a prison yard shortly before 1 p.m., according to agency spokeswoman Terry Thornton. Corrections officers responded with pepper spray and warning shots from rifles, a written report from the agency stated.
After the riot, five inmates were taken to area hospitals with stab wounds and others were being treated at the prison.
