Fascinating mystery. I have heard that David Paulides interviewed on Coast to Coast. He has been on there several times. There are some unbelievable stories about people who have disappeared in national parks and other wilderness areas. Like a little 2 year old boy who wandered off from a family picnic, I think in Yosimite, and his body was found a few days later 30 miles away. He would have had to climb several mountains which were impossible for him to climb. Somebody kidnapped him, and hiked him 30 miles in their backpack, and then murdered him? Not likely.
There are hundreds of stories of disappearances in the wilderness, about half of the people, they found dead, and the rest were never found.

I will be watching to see if they come up with a cause of death for this family. Carbon monoxide? I doubt it. Algae in the creek? Give me a break.
