There are new developments in the murder of 21 year-old Jason Wing, of St. Lawrence County.

State Police have released the results of an autopsy, performed yesterday. Officials say the remains, found off Grantville Road in the Town of Norfolk earlier this week, are that of Jason Wing of Winthrop. Doctors say the cause of death was a gun shot wound to the head, and St. Lawrence County's coroner has ruled the death a homicide.

Meanwhile, the gun believed to have been used in the murder has been recovered by investigators, 7 News reporter John Friot learned Saturday morning.

Sources tell 7 News that a gun was unearthed near the site where Wing's body was found buried deep in the ground. An excavator was used for two days by State Police crime scene investigators to locate Wing's body and weapon on private property off Grantville Road near Raymondville.

37 year-old Dustin Trimm of Winthrop remains jailed without bail on a murder charge. Authorities have described Trimm as "a fraternal friend" of Wing.

Trimm is to be back in Norfolk court for a preliminary hearing Monday morning. The case has already been presented to a grand jury but no indictment has been returned yet.
