In the early morning hours, a truck driver making his way along state highway 341 in Sumter County, South Carolina, stop to rest.

On a desolate dirt road near Interstate 95, he made the grizzly discovery of two bodies, each having been shot multiple times.

By the time the sun came up, the road was blocked off and crawling with investigators.

The victims appearing to be in their late teens or early 20s had been shot three times each at near point blank range with a 357 revolver.

For police, identifying the killer became the most prominent gold, but they had no way of knowing that more than 40 years later, it would be the identities of the victims that would be the more complex riddle.

There were plenty of clues about their origin, but nothing which could unwrap the mystery of their identities.

Months later, when police came across the murder weapon and its owner during a routine traffic stop, they assumed the case would be broken.

They had no idea that not only would their killer prove elusive, but their victims would remain unidentified beneath a slew of evidence pointing to the four corners of the United States and the world beyond.
