Riot at Sierra Conservation Center

JAMESTOWN – On Tuesday, May 19, 2015, approximately 150 inmates were involved in a large-scale riot on the A-Facility main exercise yard just after 8:00 p.m.  The riot was quelled and no staff were injured. The cause of the riot is under investigation. Several inmate-made weapons were discovered.

The majority of the inmates involved in the riot sustained minor injuries and are being evaluated by on-duty medical staff.  Those with more severe injuries were transported to local hospitals by ambulance and state vehicles. 

Two inmates sustained injuries requiring immediate transport via air ambulance and are being treated at outside hospitals.  One was in surgery this morning; CDCR does not know his condition at this time. The other suffered various injuries, and is said to be in stable condition.  Five additional inmates who were transported to local hospitals for treatment will be released back to the prison.

This incident is being investigated by the Investigative Services Unit at the prison. The Office of the Inspector General’s Bureau of Independent Review was notified.  CDCR’s Deadly Force Investigation Team will also review this incident.

The prison has been placed on a modified program and A-Facility is expected to remain on modified program until the investigation into the cause of the riot is complete.

SCC is one of only two prisons in the State responsible for the training and placement of male inmates in the Conservation Camp Program.  SCC administers 20 male camps located from Central California to the Southern California Border.
