California Department of Corrections and Rehabilitation officials are investigating the attempted homicide of a corrections officer at the California Institution for Men (CIM) that occurred Sunday night.
According to a CDCR release, officers at CIM, which is located in Chino, were conducting routine patrols when they observed an inmate, Kevin G. Roby, exiting his housing unit “wearing only his boxers with no shoes.”
“Roby ignored officers’ orders to stop as he continued walking onto the yard,” CDCR stated. “He yelled [that] he would kill anyone left on the yard and pulled out an inmate-manufactured weapon in a sheath from his boxers.”
Officers subsequently summoned a Code I and formed a skirmish line, but without warning or provocation, Roby charged at them, prompting staff to use “physical force and chemical agents” to quell the attack, corrections department officials said.
During the response, Roby used his inmate-manufactured weapon to stab an officer on the side of his head, officials added.
In the wake of the attack, the officer was transported to an outside medical center for treatment of a laceration and the effects of the pepper spray. He has since been released.
Roby has since been placed on restricted housing status and is set to be transferred to another facility. Movement on the yard where the incident occurred is being restricted so that the investigation can be conducted, officials said.
The 60-year-old convicted murderer and rapist was received at the California Institution for Men on Aug. 24, 1988, after being sentenced to life without the possibility of parole for first-degree murder and rape/resisting with force or violence with enhancements for use of a firearm.
The case will be referred to the San Bernardino County District Attorney’s Office for possible felony convictions, and the CDCR Inspector General has been notified.
CIM opened in 1941 and houses more than 2,240 minimum-, medium-, and maximum-security inmates in addition to employing approximately 1,500 people.
