OK I read that twice now. That's awesome and disturbing.
The part with the missing tongue is quite disturbing. I am positive that they were kidnapped, conducted experiments on, and then left in a manner to suggest some sort of murder. They were gone for plenty of time, and it was a snowy climate. Plus lets face it, it was at a place and a period where investigation couldn't have been optimal. That still doesn't fit in with some of the facts though, so ummm... I have nothing left to say. It was a great find! Post more if you have them.
Read this after the wiki link:
