ORONO – The medical examiner and state police Tuesday continued to investigate the shooting death of a 21-year-old University of Maine student, according to Stephen McCausland, spokesman for the Maine State Police.

Hannah M. Corbeil died of a gunshot wound to the head early Monday morning, according the Medical Examiner’s Office in Augusta. Orono police found the coed’s body in her bedroom when they arrived about 3:30 a.m. Monday.

The gun used in the shooting was recovered inside the apartment at 14 Water St., according to McCausland.

Also in the house at the time of Corbeil’s death were her roommates and fellow UM students Colin Hopper and Elizabeth Rogan and a male friend of the victim, who has not been identified.

Corbeil, a senior majoring in forestry, was from East Haddam, Conn., located in south central Connecticut. She had worked as a part-time bartender at Pat’s Pizza.

Final exams for the fall semester began Monday, according to UM spokesman Joe Carr.

Corbeil is the third UM student whose death has been investigated by state police in the past 13 months.

An 18-year-old freshman from Windsor was found about 15 feet off the path that leads from Hilltop Road to school wildlife pens and the University Forest. In November 1999, an exchange student from Wisconsin plunged to her death from her fourth-floor dorm window. Both those deaths were ruled suicides.
