Barbara Kathleen Ferree was 41 when she vanished from Chickasha, Oklahoma, after attending a party in the 500 block of South 12th Street on the evening of October 3, 1991. She was described as five feet four inches, 170–180 pounds, with brown hair and brown eyes, a rose tattoo on her right shoulder, pierced ears, and wearing a red, white, and blue checkered long-sleeved blouse, blue jeans with brass buttons, white canvas tennis shoes, and a white gold engagement ring with three or four stones. Friends called her Barbie.

Initial witnesses said a man at the party, Gary Quisenberry, told investigators Barbara had left to buy cigarettes and never returned. Other partygoers later alleged an argument with Quisenberry that ended when he threw a portable television at her, striking her in the head. No charges were filed at the time because no body or physical evidence was found.

In 1996 Quisenberry, arrested on unrelated fraud charges, allegedly confessed to killing Ferree and led authorities to a rural Caddo County site; searches there and at a Chickasha home turned up nothing. A witness also alleged Quisenberry’s sister, Belinda Sue Susie Lee, boasted of destroying Barbara’s ID and burying her. With conflicting accounts and no remains, the case remains unsolved and Ferree is listed as an endangered missing person.
