My newest scenario (of the many that play in my mind each day)...Mollie goes for a run, stops home (or doesn't, scenario could play out the same either way) and goes back out to walk to her moms. A friend drives by and asks if she wants a lift or maybe even if she wants to grab a bite to eat, she says yes and gets in (edited to add, they never made it to eat, you could feasibly insert any reason for her to get in the car). This friend has always had a secret crush on her, maybe has had a drink (or few) and has some courage to go for it and tries to make a move. Mollie politely declines. This person gets upset, loses his **** and accidentally kills her. He has easy access to a farm, disposes of the body and purposely places her phone & fit bit on WC's property because the entire town knows his history and the focus on him will give Mollie's "friend" time to cover his tracks. IF the family knows, they help to cover it up because they are tight knit and this would ruin their name, the town and their lives. I have a person in mind and an idea as to why the FBI would be brought in.
I've clearly read too many psychological thrillers and have been hooked on this story. I'm still holding out hope she is still alive but with each passing day it gets more difficult to imagine. My constant prayers and thoughts are with her family. You can tell me how crazy I am now..
