Officials at the California Correctional Institution (CCI) in Tehachapi are investigating an assault that ended with a correctional officer being stabbed in the head, reports KERO .

At 7:03 p.m. Tuesday, April 12, inmate Durrell Puckett, 30, summoned correctional staff to his cell. While speaking with staff, Puckett covered his cell door window so the officers could not see what he was doing. A medical emergency was announced, and as staff entered the cell, Puckett threw an unknown substance on them, officials said. He then used an inmate-manufactured weapon to stab a correctional officer in the head, according to officials.

The officer was taken to an outside hospital where she was treated for abrasions and lacerations. She was released from the hospital that evening and is recovering at home.

Staff used physical force, an extraction shield, pepper spray, and baton strikes to subdue Puckett. He was transported to a separate outside hospital and treated for a laceration to the back of his head. He was transferred to Corcoran State Prison and has been housed in the Administrative Segregation Unit pending an investigation.
