Ferree was last seen on October 3, 1991 in Chickasha, Oklahoma, at a party in the 500 block of south 12th Street where drugs and alcohol were being served. She has never been heard from again.

One person at the party, Gary Quisenberry, said Ferree had gone out for cigarettes and never returned. Police didn't believe the story, however; other accounts stated Quisenberry and Ferree got into an argument and Quisenberry threw a television set at her and killed her. In 1996, Quisenberry was arrested on unrelated charges. While in custody, he confessed to Ferree's murder. He said he and Ferree were drinking together at his pickup truck near Gracemont, Oklahoma when they got into an argument and Quisenberry struck her on the neck, killing her. He lead investigators to the place where he said he'd buried the body, but a search with cadaver dogs didn't uncover anything.

Quisenberry has never been charged in Ferree's case due to lack of evidence. Foul play is suspected in her disappearance, which remains unsolved.
