I filmed a quick YouTube video about it too....https://www.youtube.com/watch?v=tPX35JduPUAI visited the spot this weekend were the girl's bodies were found and can offer this insight.
This area is very isolated and very rural and very wooded. One would have to have an intimate knowledge of the area to understand this would be a perfect place to dump a body. As well, this is very much small town-Ohio. Lots of big truck traffic so a local truck driver would theoretically know about this dark lonely road.
Today, a gate blocks vehicles from accessing the road into the woods where the bodies were found. The road terminates at a parking lot and the gate blocks the way but it is open to the public (if you dont mind the hike.
It would seem in cases like this "everybody knows everybody" and small town gossip had to land n somebodies name.
