Thanks all. It all gets me a little emotional. I had an errand in his old neighborhood yesterday, which conjures up a lot of nightmares and very little sleep.
Really appreciate all of the info you folks have shared. And yes, without medication, he would not have lasted long at all.
My wife, sister in law and I need to sit down with the investigators and see what they have examined and what they didn't. His widow's family had property in another state, which could have been another place where his body could have wound up.
Make no mistake, we absolutely think he was murdered. His wife came home from the bar that night to take out the trash. If you knew her after a few cocktails, it would be obvious that was out of character. Perhaps I've watched too many episodes of Criminal Minds, but that makes me wonder if they put him in the trash.
I also believe the truck was just dumped where it was to throw off a search party. The dogs didn't track his scent off of his own truck, and with the snow, there would have been some tracks had he actually been there.
