Dept. of Corrections investigating inmate killing in Lawton

LAWTON, Okla. (AP) — The Department of Corrections is investigating the killing of an inmate at a private prison in Lawton.

The agency said in a press release the body of 29-year-old Riley Walker was discovered Monday morning at the Lawton Correctional Facility. Walker’s cellmate, 43-year-old Aaron Stone, confessed to the killing, the agency said.

Investigators with the agency’s inspector general are investigating the incident and will forward their report to the local district attorney for consideration of charges, said DOC spokesman Justin Wolf.

Wolf said he could not release details of how or why Walker was killed, but investigators do not believe the killing related to a series of gang-related attacks at six prison facilities last week. Those attacks led to a statewide lockdown of prisons that Wolf said continued Tuesday while investigations continue into the incidents.

Walker was serving a life-without-parole sentence for first-degree murder in Pontotoc County. Stone is serving time for rape, sodomy, robbery, kidnapping and animal cruelty out of Comanche County.
