SUSANVILLE, California — Officials say two inmates attacked and killed another prisoner with a manufactured weapon on a maximum-security yard of a Northern California prison.
State corrections department spokeswoman Dana Simas says prison officials are investigating the Monday attack against 33-year-old Matthew Jagger at High Desert State Prison in Susanville.
Simas says medical staff treated the Contra Costa County man before transferring him to an outside hospital where he died.
She says officers used chemical agents to quell the attack.
Simas says that Jagger was entered the prison in February 2012 and was serving a 13-year sentence for vehicle theft, carjacking, and in-prison offenses of assault by prisoner with deadly weapon and possession of deadly weapon by an inmate.
She says both inmate attackers have been transferred to the prison's segregation unit pending the investigation.
