Other than all 3 girls unwittingly finding themselves witness to something involving someone/s they could then identify, I've never come up with a motive to killing 3 young girls at the same time. There wouldn't be piecemeal motives. I can, however, think of several scenarios where two and certainly one was a target and the other two had to be silenced but were not intended victims. Then, as now, people kill for seemingly small reasons, but it would have to be something big to take out 3 people, let alone young girls and one very young one. I'm guessing all 3 could identify at least the place if not the people. Julie would be doomed if she either recognized (or knew) a perpetrator, but also the place. If they were strangers but it went down as so-and-so's house or business, you can't let Julie free.
As for why it hasn't been solved, I believe there are people still alive who could be prosecuted, either as perpetrators or accessories. Less likely but still possible is allegiance to a killer/s now deceased, perhaps in consideration of current family. What I find curious is that even with all of these people, there isn't much known about classmates or friends beyond the key players. One would think the rumor mill would have led to some leads, even if they were false leads. A triple disappearance and assumed murder doesn't quiet an entire community from gossip.
Does anyone know of any other unexpected deaths or accidents, or people who left town within a year of the disappearances?
