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.
Spokesman Lt. J. Paul Vance said Friday that police are trying to determine if the gun used by Jeffrey Giuliano, the father, was registered. It will be at least a week before the probe is done, he said.
Police said 15-year-old Tyler Giuliano was shot at about 1 a.m. Thursday in New Fairfield, a town along the New York line just north of Danbury.
A woman who was alone in the home believed someone was breaking in and called the teen's father, who lives next door, state police said. The father grabbed a gun and went outside to investigate, troopers 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.
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," Vance said.
The teen's father, Jeffrey Giuliano, a fifth-grade teacher in town, hasn't returned a message seeking comment on what happened.
The teenager was a student at New Fairfield High School, a short walk from the neighborhood where he was killed.
Superintendent of Schools Alicia Roy sent parents an email about what happened, The News-Times of Danbury reported.
"Our district has experienced a tragedy that has affected us deeply," she wrote, adding that students weren't told of the killing because all the facts weren't clear.
No charges have been filed. An autopsy on the boy is planned.
