By NBCConnecticut.com and wire reports NEW FAIRFIELD, Conn. -- During what appeared to be an attempted late-night burglary, a man fatally shot a masked teenager in self-defense outside his neighbor's house and then discovered it was his son, state police said. Police said 15-year-old Tyler Giuliano was shot at about 1 a.m. on Thursday in New Fairfield, a town just north of Danbury. A woman who was alone in the house believed someone was breaking in and called the teen's father, who lives next door, and he grabbed a gun and went outside to investigate, police said. The father confronted someone wearing a black ski mask and black clothing and then fired his gun when the person went at him with a shiny weapon in his hand, police said. Father sitting on grass When police officers arrived, the teen was lying in the driveway of the woman's home with gunshot wounds and the father was sitting on the grass. The teen was pronounced dead at the scene, police said. "All in all it's a tragedy," state police spokesman Lt. J. Paul Vance said. The Associated Press said teen's father, Jeffrey Giuliano, a fifth-grade teacher in town, had not returned a message seeking comment on what happened.
