My family owns some rural properites. They are absentee landlords. They could not care less about the care of the properties and anyone could go on them at most anytime. It would be a rare coincidence if anyone took not, especially at 2-3 AM. No way, we be able to effectively search the properties either. I've said before that I would not swear something wasn't dumped in my 1 acre suburban plot. I've seen things get lost and be very difficult to find. The searchers have a job that makes looking for a needle in a haystack simplistic. As Mr Bass, owner of Anchorage Farm out and out said, it was pure chance he noticed MH's body and he was not capable of thoroughly searching his farm.
I don't know how mess JM's kills might be, if indeed he did do these things. His face was fine when he got his photo taken at DMV. Didn't look like his face had been in any scuffle. But then it seems to me that Hannah was not in the condition to fight much. If he'd slipped something into the drink he could have given her before he left, remember, he ordered 2 drinks (beers, I believe) at Tempos, took the trouble to do this when he had her coming with him arm in arm, before they left for his car. The checker at Tempo has said she was really in bad shape as they left, needing support to walk and even stand. So there may well not have been much resistance.
In the case of MH, who knows? Friends and family are not going to say their loved one wasn't a fighter. I take these remarks with a salt shaker in hand. No one seems to remember seeing JM looking like he got into a fight with a cat at that time either. So there might not have been too much clean up needed. He's a strong brute, wouldn't take much to snap the neck or strangle with very little fight.
I don't think he went far. Too impatient, too impulsive. I hope those pings do lead LE to Hannah's body. JM's scent may not be helpful He's likely been in a lot of these places. I think the cadaver dogs with the pings are the best bet.
