Susan Reeve, 22, vanished from Demarest, New Jersey, on October 14, 1975, while walking to her parents’ home. A two-week search ended when her nude body was found in Tallman State Park in New York; an autopsy confirmed she had been raped and strangled. Her disappearance and death came days after 20-year-old Susan Heynes disappeared from nearby Haworth, and the proximity and similarity of the cases led investigators to suspect a single perpetrator.

Tenafly building contractor Robert Reldan was arrested and charged in both killings. Witnesses placed Reldan with Reeve near his station wagon on the day she disappeared, and forensic evidence tied him to the crimes. In 1979 Reldan was convicted of both murders and sentenced to life. The family later sued Reldan in civil court after he inherited millions; the suit produced a multi-million dollar award that the family donated to their daughter’s alma mater. Reldan has been repeatedly denied parole and remains in prison.

Did anyone in Demarest or Haworth at the time see Susan Reeve walking that day or notice the station wagon mentioned in reports?
