A corrections officer was stabbed inside a cell block at California State Prison, Sacramento, better known to locals as New Folsom, on Monday morning, March 9, at about 10:15 a.m. The officer suffered multiple puncture wounds, was treated on site and then taken to an outside hospital. Officials say the injuries are not life-threatening and that the officer is awaiting discharge. Staff members quickly restrained the suspected attacker and recovered an improvised weapon inside the housing unit. The inmate accused in the attack is 56-year-old Jon C. Blaylock, who is serving lengthy sentences in state custody and has been linked to prior assaults on staff.
What Officials Are Saying
According to a news release from the California Department of Corrections and Rehabilitation, officials are treating the incident as an attempted homicide that occurred at approximately 10:15 a.m. Staff used physical force to quickly stop the assault, an improvised weapon was recovered at the scene, and prison medical personnel triaged the officer before transfer to a higher-level care facility. The department states that Blaylock will be placed in restricted housing while California State Prison, Sacramento officials complete their investigation and that the case will be referred to the Sacramento County District Attorney’s Office for possible felony charges.
Inmate's Violent History
Blaylock has a decades-long history of violence behind bars and was identified as a suspect in the 2005 on-duty killing of Correctional Officer Manuel A. Gonzalez at the California Institution for Men, according to the Office of the Inspector General. That watchdog later criticized how maximum-custody inmates were processed and housed after Gonzalez’s death, noting procedural gaps that investigators said contributed to the tragedy.
Sentencing and Custody
According to the department’s release, Blaylock, now 56, was first received from Los Angeles County in 2004 and has been sentenced multiple times while incarcerated, including terms for attempted first-degree murder and assaults on staff. In August 2023 he received a life-without-parole sentence for killing a peace officer while in prison. Officials say he will be moved to restricted housing while the Sacramento investigation proceeds and that peer support is being offered to employees affected by the attack.
Broader Context
The stabbing at California State Prison, Sacramento comes amid a broader uptick in prison violence statewide that led the department to restrict movement, visits and phone access at several high-security facilities last year. The Associated Press reported that corrections officials responded to a series of homicides and other assaults on staff and inmates by launching contraband sweeps and tightening prison programming.
What Happens Next
Investigators at New Folsom are continuing to gather evidence and will send their findings to the Sacramento County District Attorney’s Office for review, according to local reports. KTLA published an early account of the incident while the investigation remains active.
