Mary Elizabeth Critchley, 37, was last seen on July 25, 1981, after a friend dropped her near exit 13 of the Massachusetts Turnpike in Framingham. She had been a student at the University of Vermont and was hitchhiking to Waterbury, Vermont, where she was living with a friend. That was the last confirmed sighting of her alive.

On August 9, 1981, Critchley’s body was found in woods off Unity Stage Road in Unity, New Hampshire. The remains’ condition prevented the medical examiner from determining an official cause of death, but authorities treated the case as suspicious and classified it a homicide. No arrests have ever been made in connection with her death.

Investigators and others have linked her killing to a series attributed to the Connecticut River Valley Killer, a suspected offender believed responsible for at least seven women killed between 1978 and 1987; many victims, including Critchley, were last seen hitchhiking. Another victim, Eva Morse, was found in 1986 about 500 feet from where Critchley’s body was recovered. Does anyone have information about Critchley’s movements on July 25, 1981, or recall seeing a woman matching her description along the Massachusetts Turnpike that day?
