A riot involving more than 160 inmates at a men’s prison in California Sunday led to one death and nine wounded inmates.

Multiple inmates were stabbed during the riot, which began just before 11 a.m. in the East Facility medium-custody yard. Nine men were taken to an outside hospital for further treatment, according to the California Department of Corrections and Rehabilitation.

Mathew Cook, 25, suffered a stab wound during the riot and was pronounced dead Sunday afternoon, prison officials said. Cook, who was convicted in April 2015, was serving a 14-year sentence for several counts of first-degree burglary in San Joaquin County.

After the riot broke out, prison staff responded immediately, firing less-than-lethal rounds and chemical agents to try to control the situation, state officials said. Deadly force was not used, and no staff members were injured.
