A Cumberland man and his wife are dead in what police said was a murder-suicide while their daughter and grandchildren were at home with them. The man, 73, and his wife, 70, were in a bedroom shortly after 5 p.m. Sunday when he apparently shot her twice in the torso with his .32-caliber handgun, Police Chief John Desmarais said Monday. He then shot himself in the head. The couple’s 40-year-old daughter and three grandchildren also lived in the home and heard the shots, he said. They called police after discovering the bodies.
