Ok so it discusses many cases(gives startling statistics about numbers of missing people), but there were some that i found the most interesting. In one case, a family is eating a picnic and one boy wanders off and is out of sight for approx. 30 sec or so. The family quickly realizes he is gone and go look for him. He is no where to be found, but the father says he may have seen a black shape flashing about between some trees. After a search including 100 or so searchers, they never found him. So he disappeared in about 45 secs time faster than anyone could ever run away, especially with the boys weight on them.
The second most interesting one was an part of the audio in which they discuss a woman who was found near the trail (forest mountains) she was meant to be on, but she was missing her tongue, had large internal bruising present on her dorsal region, AND most interestingly they found radioactive traces on her body, and in the small region surrounding her body.
