A 26-year-old inmate at a prison in Maryland died Friday after an assault in which another inmate was identified as a suspect, state police said.

The death of Javaughn A. Young, an inmate at the state correctional institution in Jessup, was the sixth inmate death in Maryland since September that has been investigated as a possible homicide.

Young was found Thursday evening lying on a walkway with a head injury. He was taken to a hospital, where he died, state police said.

His death came about two weeks after what police called the apparent homicide of Deavel M. Johnson, 22, at the state correctional institution in Hagerstown.

Johnson collapsed March 26, shortly after being found bleeding from an upper-body wound near a bunk in a prison dormitory. Police said at the time that no suspect had been identified.

In February, authorities said they were investigating the “apparent homicide” of Ricky Bailey, 51, an inmate at the North Branch correctional institution in Allegany County near Cumberland. He died Feb. 10 after being found with injuries to his head, neck and extremities, police said.

In January, state police said Michael Armstead, 53, died after being assaulted at the North Branch correctional institution on Nov. 27.

Police said Jerod Pridget, 19, died Nov. 28 at a hospital after being assaulted two days earlier in his cell at the Western Correctional Institution in Allegany County.

Homicide investigators also were looking into the death of Charles Richardson, 28, who was found wounded Sept. 27 in his North Branch cell.
