I grew up near this event. I was also a very young lad when it happened. I specifically remembered how terrified the community got. Kids would walk to school in packs of 10-20 with numerous adults. One of my neighbors walked a bunch of us to school with a shotgun. Nobody said a word about it.
When that last boy was murdered, the whole county about went ape chit.
It was terrifying. I believe there were around 500 police officers dedicated to the case.
