On November 20, 1982, 17-year-old Betsy Bacon left her home in Sea Girt, New Jersey, saying she was going to buy a pack of cigarettes and never returned. Her disappearance turned into a months-long search that ended in April 1983 when her body was found buried in a shallow grave in neighboring Tinton Falls.

Investigators linked her killing to a series of other brutal murders in the area and focused on Richard Biegenwald. An accomplice, Dherran Fitzgerald, cooperated with authorities and provided testimony that led them to clandestine burial sites, including the Tinton Falls grave where Betsy’s remains were recovered.

Biegenwald was arrested and charged in connection with multiple killings; according to later court action, he pleaded guilty to Betsy Bacon’s murder. What details about Betsy’s last hours or how she came to be in Biegenwald’s custody remain unknown to the public.

Did anyone who knew Betsy or lived in Sea Girt or Tinton Falls in 1982 notice anything unusual that night?
