HOLDENVILLE, Okla. — A prison officer has died after being attacked by an inmate at an Oklahoma jail, officials said Monday.
The attack on Officer Alan Jay Hershberger happened Sunday at Davis Correctional Facility, which is a private prison in Holdenville about 70 miles (115 kilometers) southeast of Oklahoma City. Department of Corrections officials said in a news release that inmate Gregory Thompson, 49, attacked Hershberger from behind with a homemade weapon as a group of inmates returned to a living area after recreation.
Thompson was placed in solitary confinement and an investigation was ongoing.
Thompson is serving a life sentence for a 2003 first-degree murder conviction in Oklahoma County. He also has a five-year pending sentence for a 2010 first-degree manslaughter conviction in Pittsburg County, according to prison records. This case involved the stabbing death of another inmate at Oklahoma State Penitentiary in McAlester in 2009.
The prison is a medium security facility and is operated by CoreCivic.
