This week we're going to be taking a look at the unsolved case of Julie Williams and Lollie Winans, who were found murdered in Shenandoah National Park in Virginia, USA, in 1996. To this day we don't know who the perpetrator was, but the FBI have refused to give up on their search. They're searching for anyone who was at Shenandoah at the time, who might have that piece of information that could finally lead to answers.
