A fight broke out last week at California’s San Quentin State Prison and escalated into a full-scale riot that involved as many as 80 inmates and injured 42. Not since 1982 have so many prisoners been involved in a riot at San Quentin.
Authorities have not yet determined what specifically precipitated the fight, but it came after a long-running dispute between white and Hispanic prisoners in the 900-inmate minimum-security unit, according to prison officials. Inmates from other buildings also became involved in the fracas before it was over.
