About This Episode
In 2006, the Greenville, South Carolina Police Department announced that they had connected one of their unsolved homicides from 1990 to two unsolved homicides that had occurred hundreds of miles away in Missouri. This meant that investigators were not dealing with isolated, unrelated crimes. They were dealing with a linked series. Events connected by a single source, a single method, a single offender who traveled. Yet, the announcement came with a crucial limitation: they did not know the identity of the killer. But they knew the nature of the threat.
