Debra Elizabeth Espey (6 of Clubs, Florida)

A college campus in broad daylight in a town literally called “Niceville” might be one of the last places you’d expect a young collegiate to disappear from, but in March 1973, that’s exactly what happened. Debra Espey’s case spans more than 50 years, includes a primary suspect from the beginning, and has long been thought to have connection to other unsolved cases in the Florida panhandle. But for all the twists and misdirections, detectives are hopeful they can close this case soon.
