Asking The Public For Help

New York State Police are asking the public to look at a composite sketch that was developed in 1980 of a person of interest believed to be connected to this case, and is described as a white male who would’ve been in his 20s or 30s, 5’ 10” in height, and between 140 and 160 pounds at that time period. This person would have been in the Binghamton area in November of 1980.
