Jeffrey Giuliano of New Fairfield, CT got a call about a possible intruder from his next-door neighbor sister. Armed with a gun, Giuliano left his home and ran into someone wearing all black and a mask, armed with a shiny object. After a confrontation, the masked stranger lunged at Giuliano, causing his gun to fire. Giuliano removed the mask to find that this person was none other than his 15-year-old son, Tyler.

Police arrived to find a grief-stricken Giuliano, who is dealing with a horror that no parent can imagine. State police are investigating the shooting.
