Maryland prison inmate killed in his own cell by another prisoner

A 28-year-old prison inmate has been killed in his own cell by another prisoner who was serving time in the same facility, police said.

The inmate, identified as Robert Warren -- a state prison inmate serving time at the North Branch Correctional Institution in Cumberland., Maryland -- was declared deceased in his cell on Monday by emergency medical service personnel, according to a statement from the Maryland State Police released on Wednesday.

A suspect, also an inmate, has been identified but police have not released his identity since he has not yet been charged at this time. Authorities are expected to release more information once the suspect has been charged, police said.

Maryland authorities did not say how the man was killed or how long they suspect he had been dead for when his body was discovered in his cell but they did confirm that Maryland State Police investigators are "continuing an investigation into the death of a state prison inmate in Allegany County."

"The Maryland State Police Homicide Unit was contacted by investigators from the Department of Public Safety and Correctional Services Internal Investigative Unit (DPSCS IID) about an inmate death," according to the Maryland State Police. "Autopsy results from the Office of the Chief Medical Examiner ruled Warren's death as a homicide."

State Police Homicide Unit investigators are continuing the investigation and assistance is being provided by State Police crime scene technicians and investigators with the DPSCS Internal Investigative Unit.

"Upon completion, the investigation will be presented to the Allegany County State's Attorney's Office for review regarding charges," police said.

The investigation is currently ongoing.
