Darlene "Dee Dee" Webb (9 of Diamonds, Florida)

The night was still young when 20-year-old Darlene left her friends at a local Daytona Beach bar to go get some shut-eye before work the following morning… but little did they know, as she walked out into the darkness of the night, that’d be the last time they’d ever see her. Today, detectives are still as baffled as they were back in 1983.
