Old Forge, NY -- A Rochester man staying in a motel in Old Forge shot and killed his son early this morning thinking his son was an intruder, state police said today.

Michael Leach, 59, an officer with the Parry Police Department in Wyoming County, called 911 at 12:51 a.m. from the Clark Beach Motel to say that he just shot someone he thought was an intruder, troopers said.

Instead of an intruder, Leach shot and killed his son, Matthew S. Leach, 37, of 23 S. Heppler St., Rochester, troopers said.

Leach used his department-issued .45-caliber Glock handgun in the shooting, troopers said. He was taken to St. Luke's Hospital, Utica, after the shooting for what troopers described as a "medical issue."

Troopers are continuing to investigate the shooting.
