Oy. read Krakauer's expose -- the allegations are easily verifiable, especially the financial misdeeds. They still need to be verified, however.
Unfortunately, though I hope I am wrong, I believe the allegations are true. I knew someone *exactly* like Mortenson is portrayed by Krakauer. He was brilliant at telling a story (which sometimes even had a grain of truth in them), raising money (from people who believed his stories), and using the church finances as his own personal ATM. Manipulated his board. Hid information. Fit the profile to a capital T.
I think people like the one I knew believe their own stories. That's what makes their lies so difficult to detect -- the don't think they are lying. They are convinced that they are savior types, doing good.
When I worked as an editor for an international missions newsletter, I learned very quickly to sort people by asking one question: Who originated the story of their daring or delightful deeds? If I heard about a person or ministry from others, then I would pursue it.
If, on the other hand, a missionary was busy telling the story themselves, or if I heard it from people who had heard it from said missionary, alarm bells went off. And the alarm was always right. I can't think of one instance in which a truly good person spent lots of time talking about how good they were. Not in any context.
So, who told Mortenson's stories? Who verified them?
P.S: Franzilla. I'm so sorry if it turns out to be as bad as I think it may be. BUT.... I know how you can find someone who is really really good. Just wake up every morning and be that person.

And if you fall down and are not really good one day, just be honest about it, then get up and try again.
Everyone has warts -- my role models, people like George MacDonald, Gandhi, Bonhoeffer, Corrie Ten Boom, Dr. Martin Luther King, Flannery O'Connor or Anet J. (to name a very few) all moved the world to be better. And they were all just human.
