Lottie Wilson, 90, vanished from her Davie, Florida home on August 1, 2000. She lived with her son James Wilson and suffered from high blood pressure, diverticulosis and severe arthritis that left her fingers deformed. Because she had no history of leaving without telling anyone and her frailty made wandering unlikely, authorities treated her disappearance as suspicious from the start.

Investigators say James and Lottie had a contentious relationship and suspected she may have died of natural causes with her body then disposed of in the Everglades to avoid scrutiny. Extensive searches turned up no remains, and no charges were ever filed due to a lack of physical evidence. The case remains unresolved.

Does anyone who knew Lottie or the family have information that could finally clarify what happened to her?
