What do you know about Man Eaten by Grizzly Bear?

In Alaska on October 5th, Timothy Treadwell and Amy Hugenard's were found dead at their camping sight. Treadwell had a passion for grizzly bears and would frequently follow them and become very comfortable around them. He even would pet them and play with cubs. However, on this day, Treadwell was not carrying bear repellent sprat and unfortuently his body was found mauled by a bear who had eaten him first, then his wife. Rangers have evidence of this event due to a recording found which is 6 minutes long of the two being eaten and torn apart. Rangers have refused to share the tape with anyone due to its ability to leave a harrowing impression.
