California Department of Corrections and Rehabilitation (CDCR) officials are investigating the attempted homicide of a peace officer at California Medical Facility (CMF) in Vacaville, CA.
On May 21, 2025, at approximately 1010 hours, Inmate Dannunzio Patron attacked a correctional officer with an improvised weapon during a cell extraction.
Officers utilized physical force to quell the incident. During the incident, one officer sustained lacerations to his left forearm from the inmate’s weapon, and two responding staff members reported knee pain. The injured officers were transported to an outside medical facility for treatment.
Inmate Patron was transferred to another institution for placement in restricted housing. The case will be referred to the Solano District Attorney’s Office for possible felony prosecution.
Patron, 38, was most recently received from Fresno County on Dec. 30, 2024. He was sentenced to eight years for assault with force likely to produce great bodily injury as a second striker.
