I think the fact they searched there with so much manpower suggests that they had more than a tip that she might be there or evidence would be there. Something had to alert LE to these properties/people/area. I have no idea if it was the address, people associated with the address, vehicles that come and go. etc.. but why would LE search an area that far away from where she was without a really good reason. It wasn't like it's a farm along a typical running route.. it had to be some credible tip or evidence.. either Fitbit data, cell contact or some contact with a person that is known to that area. Not saying it has to be property owners or anything.. but just even people that are often there. maybe working or delivering to that location. Just seems way to random of a location to not be based on something good.
