I too would love answers to these questions.
I will say I think his goal was that she be found. No way he risks moving her so she won't be found because at that point she hadn't been found so what made him think she would be? I don't know where the first burial was, but I can say where he put her was not well hidden. If he didn't want her found he could have went into the forest and dug a deep hole. He instead went right off a highway and barely buried her. I think he wanted her found or he never would have risked moving her.
Barry was fanatic about guarding his perimeter during Andy's search. That he'd exert the castle domain isn't shocking but it never sat right with me. People were searching for his missing wife and instead of welcoming it or being moved by it, he goes full Rambo, full fortress. And just like his head-shaking infomercial, he broadcasts tone deafness. Does he seriously have no idea how poorly he comes across?
Weird time to get all trespissy.
Was he protecting her burial site? Seems like. And if not that, how about the access point? He knew that territory like none other. I have long suspected that his two-week, off-grid, Bible-toting absences weren't far away a'tall. Plenty of time for dumpster dust-ups. Plus we know he tracked that mountain lion. I suspect he hoped to lure it to PP where he could shoot it, claim self-defense -- just protecting the fam he cared so much for. And then with a wink-wink, handshake-handshake, backscratch-backscratch, keep the hide, keep the cat, take credit as the hunter, stuff it and park it in his living room, God-granted dominion.
Chances are good he put his trail cams back up and IMO he could see if any two-legged animals were prowling in the direction of his missing Mrs.
So... either within his property line or a decent pitcher's stone's throw up the mountains behind PP. I would not be shocked to learn that Barry knew of a mine shaft with two entry points, perhaps one side marked and sealed, and well above the frost line.
Consider, if the State really did have a location in mind, under some 8 feet of packed snow, I have to think they hid a nice little camera in the area....
But if Barry, the mountain lion whisperer, had a back door, he may have removed her remains without ever touching thst mine entrance from the tip. I contend that Suzanne's body was in water, for at least a time. From ice melt that often exists as a tributary under a shelf of ice...
Did he move her before he sold PP?
That package debacle was not an honest mistake. If it were, he could easily have called the new owner, explained the situation and sent his proxy to retrieve it straightaway.
I think it was a test. To see if they had cameras, to see what would happen.
IMO Barry neeeeeeeeded access to thst property. For all we know, they ran similar tests from other corners, in order to find where the cameras were and weren't.
Picture any of those uninspired rock clusters at PP. Could well have been hiding a secret mine shaft Barry alone discovered. Making it truly the perfect place to conceal a body. For the very reason that he could access it by trapdoor if need be. If my theory holds.
No mention of predation on Suzanne's bones, though an indication they've been unearthed at Moffat. I don't think any four-legged animals did that. Or there would have been teeth marks IMO.... The only animal that touched her was the one she was married to.
His motivation? IMO same as always, done it his whole life -- money, money, money. Root of all evil and backbone of the man.
