On July 10th, 1991 a young woman, known to her friends in El Dorado, Arkansas as Mercedes, was murdered in a motel room by James McAlphin. He was sentenced to 15 years in prison. Case was closed for him but investigators still had a problem to solve. Mercedes was living under a stolen identity and no one knew who she really was. If it wasn't for DNA technology and years of dedication from two women in blue, then the El Dorado Jane Doe's true identity might've never been discovered.
