In an alleged attempted burglary, a man shot a masked teen in self-defense, and then later discovered that the boy was his son.

15-year-old Tyler Giuliano was shot early Thursday morning in New Fairfield. Jeffrey Giuliano, Tyler’s dad received a call from his sister who lived next door and believed that she had a robber in her home. Jeffrey immediately grabbed a gun and headed over.

When he arrived outside his sister’s home, he was confronted by a man wearing a black ski mask. When the person lunged at him with a shiny weapon, Jeffrey fired in self-defense, fatally wounding the attacker.

When police officers arrived, the teen was lying in the driveway and was pronounced dead on scene. An officer pulled back the mask and revealed that the burglar was actually Jeffrey’s son Tyler.

“It’s something out of a Hollywood script,” explained Officer John Hodge. “You certainly don’t expect it to happen in your own small hometown where there’s very little crime.”

“All in all it’s a tragedy,” Spokesman Lt. J. Paul Vance added.

Tyler Giuliano was a sophomore at New Fairfield High, and was described as easygoing and a plane enthusiast. Investigation is under way on possible motivations, or if this was just a prank gone horribly wrong.

Jeffrey Giuliano is a 5th-grade school teacher who also taught music and zoology camps for his students.

“[Jeffrey] wanted to teach in the community he grew up,” School superintendent Alicia Roy said. “He connects with the students. He’s a caring person. Very interactive class.”

No charges have been filed, although the investigation is still ongoing.
