New York State Police continue to search for leads in 45 year old homicide case

The New York State Police are renewing efforts in the ongoing investigation into the homicide of Barry G. Marquart - a case that has remained unsolved for more than 45 years.

Investigators have continued to actively renew evidence and pursue leads in an effort to bring justice to Barry Marquart and his family.

As part of this renewed investigative push, the New York State Police are asking the public to take a closer look at a composite sketch developed in 1980 of a person of interest believed to be connected to this case.  The individual in the sketch is described as a white male who would’ve been in his 20’s or 30’s in 1980, 5’ 10” between 140-160 lbs. He would’ve been in the Binghamton area in November of 1980.

The individual is not currently considered a suspect; however, he has never been publicly identified and may have critical information related to the investigation.

Investigators are urging anyone who may recognize the individual depicted in the sketch, or who may have information regarding the death of Barry Marquart, to come forward.  Even seemingly minor details could be significant.

Barry Marquart, an Oneonta native, was reported missing on November 9, 1980, by his father.  At the time, Marquart was 30-years-old and living in Binghamton with a roommate who reported not seeing him for two days.

Marquart’s vehicle was later located at a rest area off Interstate 81 in the town of Dickinson.   His body was subsequently discovered in the Chenango River, approximately 500 feet behind the rest area.  An autopsy determined the cause of death to be drowning but also indicated he sustained injuries consistent with blunt force trauma to his head and face.

Marquart’s wallet was later located in Otsiningo Park and his watch was missing at the time that he was found. 

The New York State Police remain committed to seeking justice in this case and encourages the public to share information to help generate new leads.
