On the evening of July 4, 1977, 26-year-old Billie Lynn Groff vanished from her home on Westview Avenue in Hubbard, Ohio. When the family returned around 11:00 PM, Billie was gone. She left behind all her personal belongings, including clothing; she had been wearing a white t-shirt, blue cut-off jeans, and thong sandals.

A missing person report was not filed until two days later. Investigators searched woods and lakes and even excavated part of the Groff backyard without finding evidence. Friends and family described the marriage as controlling and abusive, and the couple was reportedly going through a divorce; the husband provided police a four-page list of his wife’s perceived shortcomings, a detail that fueled suspicion among those close to the case. Decades later the Hubbard Police Department still lists the disappearance as an open investigation; no charges have been filed.

The unanswered question at the case’s center is who Billie meant by they when she said someone was coming up the driveway. If anyone knew Billie, her movements that night, or saw anything in Hubbard on July 4, 1977, please share what information is available.
