Melody Marie Gay was 19 and living in Collier County, Florida, when she vanished from her overnight shift at a 7-Eleven on the road toward Marco Island in the early morning hours of March 7, 1984. Deputies determined she disappeared from the store at about 4:30 a.m.; her purse remained inside, the cash register was undisturbed, and no obvious signs of a struggle were reported.Four days later, on March 10, her body was found floating face down in a canal off White Boulevard in Golden Gate. Authorities said she had been raped and strangled.

Investigators interviewed family, friends, former boyfriends, acquaintances, and people who had visited the store while she worked, and a primary suspect was identified at one point but never publicly charged.The case drew some outside speculation linking Christopher Wilder to the killing, but investigators later said he had been ruled out. DNA testing in the mid-1990s produced profiles that did not match the people under scrutiny, and detectives have acknowledged it remains possible more than one person was involved.

If anyone knew Melody, worked with her, or saw anything near the store that night, can you help investigators by sharing what you remember?
