WILTON -- Police have charged a 12-year-old boy with manslaughter and his 56-year-old father with endangering the welfare of a child in connection with the shooting death of 12-year-old Nicholas Naumkin of Wilton last Wednesday.

Naumkin, a seventh-grade student at Maple Avenue Middle School, was visiting a classmate at the O'Rourke residence at 1 Birchwood Drive Wednesday. Police said Monday that the two boys were left alone in the residence for more than three hours to play video games, and that they "found" a handgun and ammunition in the father's bedroom.

The two boys were handling the gun about 7 p.m. Wednesday when it fired, striking Naumkin in the head. Naumkin, of Knollwood Drive, was taken to Albany Medical Center, where he was later pronounced dead.

The handgun, which is registered to 56-year-old Edward O'Rourke, was unloaded and sat in a holster in the man's bedroom, hidden under clothing in a dresser drawer, according to police. Ammunition was similarly hidden in a different drawer, police said.

According to a Saratoga County Sheriff's Department press release, the two boys first found the unloaded handgun and were playing with it when they returned to the father's bedroom and founded a loaded ammunition clip.
