Just my opinion, but I don't think JM's initial plan for that Saturday evening was to kill someone. My guess is he was looking for someone to have consensual sex with and thought he had found that someone when he stumbled upon an obviously-impaired Hannah. Perhaps she didn't put up enough resistance early on, as she seemed to be with him willingly for a while. I believe she got in his car, perhaps willingly, and he took her somewhere, or maybe even in the car, and he made his move and she resisted. At that point, I believe he became enraged and decided to take what he wanted, and probably killed her immediately after or just before, either accidentally or, more likely, as a continuation of his rage that she put up a fight. What I am getting at with all this is, I doubt he had a tarp or shovel or any such items in his car with him, so he probably just took her somewhere remote that he was familiar with and dumped her. My guess is that if and when she is found, (and I pray she is), she will be within a few yards of a road and minimally covered by brush or the like, but probably not buried. As always, this is all just my opinion.
