The death of an inmate at a Lost Gap prison facility has been ruled a homicide, authorities said.
Sheriff Billy Sollie said a state pathologist determined blunt force trauma to be the cause of death of Lonnie Grisham, 58.
Sheriff's deputies said they found Grisham's bruised and bloody body in his cell Monday. No weapons were found in the cell.
Sollie said Grisham's roommate Tyrone J. Wilson was being held in isolation. Wilson, 29, is being questioned about the death, authorities say.
East Mississippi Correctional Facility, in the Lost Gap community west of Meridian, is a 100-acre prison opened in April 1999 by Wackenhut Corrections. The prison is designed to house inmates with special needs, including those with psychiatric illnesses.
