My mind keeps going back to the description of Hannah given by the "Abby" who was the checker at Tempo and one of the last people to see Hannah alive. THat description is of someone failing, in terms of being able to stand on own, not at all of the young woman we see on the video footage within an hour of that time who is walking stridently, even running and not on the verge of collapse, not needing physical support. Why would a predator who has his prey right in his arms waste another 15-20 at least, stopping at a place like Tempo and buy 2 drinks when he could have gone straight to his car with her. When you know he wants to do something, right away, the juices are flowing, the urges are there? Why would he spend over $15 on the spot? And she would probably very gratefully drink down a cold beer. She'd be thirsty from all that running, walking and be a bit dehydrated from drinking earlier. One more beer after all that time of running around from an upscale place like Tempo from someone who offered her home certainly sounded just fine. So I think something was likely in that beer and that JM had a perfectly easy ride and perfectly compliant victim. Makes it even more horrible, more demonic that he's kill her when he's done. He could have taken her back to town, left her off in a back alley somewhere alive to wake up with no memory or a vague memory of what happened, and maybe just left things as that.
