Officials investigate an attempted murder of a peace officer at Kern Valley State Prison

DELANO, Calif. — Officials with the Kern Valley State Prison are investigating inmate Elrader Browning, 39, after he used an inmate-made weapon to attack four correctional officers.

While Browning was being search, officials said he used the weapon to stab the officers repeatedly.

In a press release, officials said one officer had a stab wound to the face and a laceration to the neck. Two officers suffered sprained wrists and another officer had a sprained knee.

All four officers are recovering outside of the hospital.

Browing was serving a 41-year-sentence with possibility of parole for second-degree murder and assault with a firearm. He also received a conviction from Del Norte County in June 2003 for attempted second-degree murder by a prisoner with a deadly weapon or force likely to produce great bodily injury, his second strike.
