Frankie Lyvonne Duvall, known to family as Bonnie, was 39 when she disappeared from Loco, Oklahoma on May 10, 1986. She was working at the Loco Café and reportedly left on foot to retrieve an ingredient from the nearby family home; she never returned to the café and was never definitively seen again. Frankie is described as having brown hair and blue eyes.

Accounts of her last known movements conflict. Some witnesses said she left work to get supplies and did not come back; her husband said he last saw her at home; older children recalled her asleep on the couch the morning they left for school. The husband did not report her missing until three days later. A young child later told a grandparent they saw the father dragging a large dark bag and putting it in the cellar. The family rejects the idea she left voluntarily; her vehicle remained at home.

The Stephens County Sheriff’s Office handled the investigation, which had been cold for years and was reportedly reopened in 2017. No definitive answers about her whereabouts have been disclosed. Does anyone who knew Frankie, the family, or that small community in 1986 have information that could help explain what happened?
