The Office of the Chief Medical Examiner said today that Michael Dugas, who was shot and killed by Norwich police after pointing a gun at them, died of multiple gunshot wounds.

The medical examiner ruled his death a homicide — a ruling that means one person killed another and does not attempt to explain intent.

Norwich police said they were called to the neighborhood park in the area of Laurel Hill Avenue and Center Street at 7:18 p.m. Sunday for a report of a man with a gun.

When officers arrived at the scene, they found 52-year-old Dugas, who told them he had a gun. Dugas was despondent and refused to follow officers’ commands, police said.

Police said they attempted to communicate with him for an unspecified period of time. Dugas suddenly drew a handgun from his pocket and pointed it at them, police said.

Police said they were forced to defend themselves and shoot.

Seven police officers were placed on administrative leave while state police investigate the shooting.

State police said part of the investigation would include how many shots were fired and who discharged their weapons.
