California Department of Corrections and Rehabilitation (CDCR) officials are investigating an attack on a staff member at Salinas Valley State Prison (SVSP) as an attempted murder.
On Aug. 28, 2026, at 1243 hours, staff saw Inmate Sean W. Cunningham strike a healthcare staff member from behind and then run away. Staff immediately came to the aid of the employee, initiating life-saving measures and activating 911. The injured employee was transferred to an outside medical facility for treatment. An inmate-manufactured weapon was discovered at the scene.
Inmate Cunningham was subsequently located and placed into restraints without further incident. He has been placed in restricted housing pending an investigation by the SVSP Investigative Services Unit and the Monterey County District Attorney’s Office. The Office of the Inspector General was notified.
Cunningham, 43, was most recently received from Los Angeles County on April 8, 2009. He was sentenced to 49 years, four months for second-degree robbery as a second striker, with enhancements for use of a firearm, inflicting great bodily injury, and prior felony conviction of a serious offense. He was sentenced on Nov. 30, 2016, by Kern County to two years, eight months for resisting or deterring an officer with threat or violence as a second striker, an in-prison offense.
