State police said early Friday that Prince George’s County police received a call for a report of a cutting at the Christa McAuliffe Residential Community building about 8 p.m. Thursday and responded with university officers.
Police say the victim, Dominique Frazier of Washington, was found unconscious in a second-floor hallway of the dorm.
Authorities say Frazier was taken to a hospital, where she was pronounced dead a short time later.
The roommate, who has not been charged, fled the scene but turned herself in to county police about four hours after the incident.
The university canceled all classes Friday.
