Corcoran State Prison inmate allegedly stabs two guards with a homemade weapon

An inmate at Corcoran State Prison is being investigated for attempted murder after allegedly attacking two correctional officers with a home-made prison weapon.

At 4 p.m. Monday, John Nieto, 28, began stabbing a correctional officer. Another officer intervened and Nieto began stabbing that officer, the California Department of Corrections and Rehabilitation said.

Prison staff used pepper spray, batons and physical force to subdue Nieto as he kept striking staff with the weapon, and finally put him in handcuffs and leg restraints.

Two officers were taken to hospitals for treatment of minor stab injuries. Both were treated and released and are recovering at home. Nieto was not injured and is now in the administrative segregation unit.

Nieto, 28, has been at Corcoran since August 2008. He is serving a 21-year sentence for voluntary manslaughter in Los Angeles County.

Corcoran prison opened in 1988, employs about 2,500 people and houses about 3,000 inmates.
