Another thing. Since JM can't control himself, I would have imagined he would immediately take HG to a grassy area first. And then drive her body away. In this scenario, the body would be in the trunk. Maybe that's why no one saw her get in his car. He took her to a grassy area and then returned with his car to dispose of her body...
a local's comment: I don't think there is any such grassy area in the downtown mall area that would be out of sight. There are secluded areas close to tempo, but they're in the opposite direction from which LJ and HG were seen walking away from tempo.
She was seen walking, leaning heavily on him, and she was expected at another party several blocks away. It seems that LJM's MO was to "offer rides" to young girls in distress, and HG was in distress and needed a ride.
JMO: I'm guessing he took her straight to his car. He started driving, all charming. From the mall, you're can be on forested 2 lane roads within 5 minutes. There are a 4 exits from town I suspect he might consider: Old lynchburg, taking him very close to the area where he grew up off of Ponderosa trail, Rt. 29 and the area where Morgan's body was found (and the road to Liberty University), or Rt 20 towards Scottsville. The three of these roads are connected by Red Hill Rd. There are some large farms and forested mountains, several ponds, and even a quarry or two scattered around. Alternatively, he would have taken Rt 20 north - where police appear to be searching intensively. This is unsubstantiated, but a friend who has known LJ since he was yound indicated that he has family that lived in a small area behind Key West. If you were to continue up Rt 20, there are some massive horse farms in that direction.
JMO - I think JM took MH to a spot by Blandemar Farm Pond, which he knew because he's a fisherman. Behind a small shed there, he had his way with her, and carried (or perhaps chased) her down the unfenced pasture to a fence line where she was found. I wouldn't be surprised if he let Hannah escape and run down the pasture, just so he could run her down and tackle her...playing with her and showing his physical dominance like he did with the guy he put a wrestling hold on in Blue Light Grill hours before Hannah's abduction - and breaking bones in the act. I think he really is simple but does not repeat his mistakes. He raped the fairfax woman behind a shed in too public a place and was almost caught. Since then it appears he has disappeared with his victims, probably to empty countryside. I think, since MH's body was found, he will be even more careful with HG. Rather than dumping her in a field, she will be covered, likely in a forest.
