CDCR investigates attempted murder of two peace officers

According to a statement from the California Department of Corrections and Rehabilitation, officials are investigating the attempted homicide of two peace officers at the California Health Care Facility.

At 6:52 a.m. Thursday, April 11, while conducting a mass search of the facility, two correctional officers were attempting to place Brandon S. Keen, 39,  into handcuffs. Keen resisted, retrieved a weapon and stabbed one officer twice and sliced another officer’s hand. Staff immediately responded and used physical force to restrain him and quell the attack. During the response, a third officer’s hand was injured.
