Prince George's County police were called around 8 p.m. Thursday for a report of a cutting at the school and responded with university officers.
Police identified the victim as Dominique Frazier of Washington, who was a student at Bowie State. Frazier was found unconscious in a second-floor hallway. Authorities say she was taken to a hospital, where she was pronounced dead.
Police say the suspect is Frazier's 19-year-old roommate. Investigators believe the two women got into an argument in their suite that turned into a fight.
The roommate fled but later turned herself in to county police. Police have not identified her until charges are filed.
