Three men attacked a fellow inmate at the Maryland House of Correction Annex in Jessup yesterday, stabbing him eight times and puncturing his lung, prison officials said.
The 25-year-old victim and 47 other inmates were outside a housing unit at 1: 50 p.m. during a recreation period when three men accosted the victim. Officers found a homemade knife.
"We have found one weapon at this time," said Dave Towers, a spokesman for the state Division of Correction. "We are searching for more evidence."
The inmate, who was serving a life sentence for first-degree murder, was taken by MedEvac helicopter to the Maryland Shock Trauma Center in Baltimore, where he is listed in stable condition, Towers said.
One of the three attackers was slashed on the cheek and treated at the prison, officials said.
Three corrections officers were monitoring the prisoners at the time of the incident.
The victim had been at the facility since 1996, Towers said. Officials would not release his name because his family had not been notified, he said.
Prison officials are trying to determine how the knife was fashioned and how the fight began, Towers said. They are also looking into ways to avoid incidents.
"We are constantly in the process of shaking down cells," he said. "But inmates are very inventive."
State police in Glen Burnie are investigating the stabbing.
