Prison guards fired rubber bullets and pepper spray to quell a riot on Sunday involving more than 160 inmates at a central California penitentiary in which one prisoner was stabbed to death and eight others wounded, state corrections officials said. No staff members were injured in the disturbance, which erupted shortly before 11 a.m. at the California Men's Colony near San Luis Obispo, and took less than 10 minutes to bring under control, said Lieutenant Monica Ayon, the prison spokeswoman.
