An inmate at the High Desert State Prison in Susanville died Monday after being attacked by two other inmates, according to the California Department of Corrections and Rehabilitation.
The incident occurred after 1:30 p.m. in one of the prison’s maximum security yards, when two inmates used an inmate-manufactured weapon to attack the victim, CDCR said in a news release. Prison officials intervened, using chemical agents to subdue the attackers.
The victim, Matthew Jagger, 33, of Contra Costa County was treated on scene and transferred to an area hospital, where he later died.
Jagger was transferred to CDCR custody in February 2012 and was serving a 13-year sentence for vehicle theft and carjacking, along with in-prison offenses of assault with a deadly weapon and possession of a deadly weapon by inmate, officials said.
The attackers, whose names were not released, are being held in the segregation unit pending the outcome of the investigation. No prison staff was hurt in the incident.
Monday’s episode comes after other recent inmate deaths. Jonathan Velarde, 23, also an inmate at the Susanville prison, was killed Aug. 16 after being hit by warning shots fired by prison guards during a riot.
Hugo “Yogi” Pinell, who was part of a group of inmates that tried to break out of San Quentin Prison in 1971, was killed Aug. 12 during a stabbing melee involving 70 inmates at New Folsom prison.
