An investigation is underway after a California inmate convicted of murder was accused of trying to kill a prison psychiatrist during a one-on-one meeting.

On Aug. 29, Jose L. Ramirez, 35, allegedly attacked a psychiatrist at the California Medical Facility, a state prison in Vacaville, according to the California Department of Corrections and Rehabilitation (CDCR).

Officials said a correctional officer quickly intervened to stop the attack. An improvised weapon was found at the scene.

The psychiatrist was taken to a local hospital for treatment and officials said he was expected to recover. Following the attempted homicide, Ramirez was placed in restricted housing pending an investigation.

Ramirez was received from Los Angeles County on Dec. 9, 2019. He was serving a life sentence with the possibility of parole for first-degree murder with enhancements that included the use of a firearm, felony arson and more.

The case will be referred to the Solano County District Attorney’s Office for possible felony prosecution.

The California Medical Facility provides medical, psychiatric and dental health care needs to male inmates incarcerated within the CDCR. The majority of inmate-patients at CMF reside in an outpatient setting and receive health care in outpatient clinics.
