It's a story made for true crime obsession.

On February 22, 1996, two eighteen-year-old girls were found murdered in a seedy establishment named "Exotic Tan for Men," just off Church Street in Nashville.

The case quickly went cold, and that's how it remains today. 

How could such a brutal murder go unsolved for so long?

It even has an ominous-sounding name: The Tanning Bed Murders.

It really is amazing that so little is known about the deaths of Melissa Chilton and Tiffany Campbell.
