(13-WHAM) An indictment charging Michael Leach, 59, with second-degree murder was unsealed in Herkimer County Court Wednesday morning.

The indictment accuses Leach of intentionally killing his son. He also faces a weapons charge for the use of his service revolver.

In July at a motel in Old Forge Leach shot and killed his son Matthew, 38, while the two were on a semi-annual trip with the Rochester-based Punisher's Motorcycle Club. 

At the time it was reported to be an accidental shooting.  Leach told authorities he thought his son was an intruder gaining entry into the motel room they were sharing that night.

The father called 911 and the owner of the Clark's Beach Motel where the shooting happened was actually one of the EMT's who worked to revive Matthew Leach. 

Leach was transported 55 miles away to St. Elizabeth Medical Center in Utica where he was pronounced dead. 

Michael Leach, a retired RPD Captain and part-time Perry Police Officer in Wyoming County, was emotional at the scene according to motel owner Dan Rivet Jr. 

"A Town of Webb police officer had shown up and he was speaking with him (Leach) in the back of the room and he was very, very distraught," Rivet told 13WHAM News days after the fatal shooting.  "It was just a horrible, horrible tragic situation (and) we just felt so bad."

Father and son had been on an escape weekend with the Punisher's Motorcycle Club.  The group includes various members of law enforcement in Monroe County and they had stayed at Rivet's motel in past years.  Members of the group were reportedly drinking outside of their rooms prior to the shooting. 

At 12:51 Leach called 911 to report the shooting. His son was reportedly entering their motel room when his father shot him with his .45 caliber service revolver according to State Police.

Michael Leach's brother is an RPD Captain and his father was former RPD Chief Delmar Leach.  He retired as a Captain in 2001.

Matthew Leach worked for RDG Security at a number of popular nightspots in Rochester's East End.  He married his wife two years ago.  

Leach grew up a standout athlete and wrestler.  He later turned his passion for wrestling into a desire to coach at Greece Athena, Pittsford, and Brockport in recent years. 

 "He had leadership qualities that were out of this world, you would never find somebody that is as loyal and humble as Matt,” friend and RDG Security coworker Aaron James told 13WHAM News in July. “[He] always talked about his family a lot, talked about his love for coaching and wrestling, loved his kids, loved us down here he was just the ultimate team player.”
