Police are hoping you can help as they continue to investigate the murder of a former Hudson Valley assistant superintendent.

As part of "Cold Case Tuesday," New York State Police released information about the 1997 homicide of Richard H. Aderson.

Around 6:00 p.m. on Wednesday, February 5, 1997, police responded to Interstate 84, approximately a fifth of a mile west of Exit 12 in the Town of Fishkill after the victim contacted 911 and reported that he had been shot.

Aderson, 47, of LaGrange was heading east on I-84 in his 1995 gray four-door Volvo sedan when he was involved in a fender bender about four miles from the Newburgh-Beacon Bridge.

Both vehicles pulled over to the side of the roadway by Exit 12 in Fishkill and reportedly were involved in a verbal altercation.

Aderson, a former assistant superintendent for the Valley Central School District, called Dutchess County 911 and reported that he had been shot by the other driver who had fled eastbound on I-84.

On the way to the hospital, Aderson gave authorities details on the suspect before dying from his injuries.

The suspect was described as being a white male in his late forties with a medium complexion, approximately 6’0” tall and with a thin build. He was said to have a receding hairline, a thin nose and was wearing aviator-type eyeglasses.

He was driving a Jeep Cherokee, possibly a 1997 model, that was believed to be green in color and may have had New Hampshire license plates.

Aderson’s death continues to be actively investigated by police.

Over 3,000 leads have been followed throughout the 20-year investigation, which has taken members of law enforcement across New England. However, the case still hasn't been solved.

Anyone with information regarding this investigation is asked to contact the New York State Police Bureau of Criminal Investigation in Wappinger by calling (845) 677-7300. Please refer to case # 3021797. All calls may be kept confidential.
