JESSUP, Md. -- Three prison inmates who may have gotten free by jamming the locks of their cells stabbed a guard to death in Maryland's troubled House of Correction, prison officials said yesterday.
It was the second killing of an on-duty corrections officer in the state this year.
David McGuinn, 42, was counting inmates alone in the maximum-security prison late Tuesday when he was attacked and stabbed several times in the neck and back, said Major Priscilla Doggett, a spokeswoman for the Maryland Division of Correction.
The prison was in lockdown yesterday, and security teams from other prisons were sent to assist with a search of the facility, Doggett said. She said the three inmates suspected in the attack may have jammed their cell doors . The three had not yet been charged late yesterday.
The Maryland House of Correction, built in 1878, has been racked by violence in recent months. Three inmates have been killed there since May, and inmates assaulted two officers in April.
This week, a new warden was named in an effort to restore safety inside the 1,100-bed prison.
Correctional officers union chief Ron Bailey said the prisons are understaffed, morale is low, and the system is in crisis. In January, another Maryland corrections officer died after he was shot in the face with his own gun, allegedly by an inmate he was guarding at a Hagerstown hospital.
