State police say they're seeking the public's help in solving the killing of a 30-year-old man whose body was found in an upstate New York river 36 years ago.

Investigators say the body of Barry Marquart of Binghamton was found in the Chenango River north of his hometown in November 1980, two days after he was reported missing by his father.

Police say his car had been found parked in a rest area along Interstate in Dickinson. His body was found submerged nearby in the Chenango River. Troopers say his wallet was found nearby but his watch was missing.

An autopsy determined he had suffered injuries from blows to his head and face. The cause of death was drowning.

Troopers say the cold case remains open. Anyone with information regarding this case is asked to state police at 607-561-7400.
