Author and investigator David Paulides has focused his attention for the last 11 years on evidence of people vanishing in the wilderness under mysterious circumstances.
In the first half, he discussed his newest research: disappearances in Idaho and how cases of missing people cluster in various areas.
He outlined a set of "profile points" or commonalities in the incidents he's studied, which include the lost discovered in areas that were previously searched numerous times, and when found alive, they have a lack of memory about what happened.
