Missing 411 | Are These People Really Gone?

One of the most confusing and frustrating investigations by law enforcement is related to people who disappear in highly rural locations, forests, plains, deserts, and regions with few residences. These cases offer no witnesses, few clues, and a strange lack of evidence. Where are these people? How did they disappear without leaving a scent trail no tracks and a distinct lack of physical evidence?
David Paulides is a former police officer who is now an investigator and writer known primarily for his self-published books dedicated to proving the reality of Bigfoot and establishing the Missing 411 conspiracy theory.
Following his work on Bigfoot, Paulides' next project was Missing 411, a series of self-published books and two documentary films, documenting unsolved cases of people who have gone missing in national parks and elsewhere.
According to Paulides, his work on this subject began when he was doing research in a national park and an off-duty park ranger found him and expressed concern about the questionable nature of some of the missing person cases which occurred in the parks. The ranger knew Paulides' background and asked him to research the issue. Paulides obliged and asserts that he uncovered multiple lines of evidence suggesting negligence on the part of the park service in failing to locate the missing people. He broadened his investigation to include missing people from across the world, and this led to his belief that he has uncovered a mysterious series of worldwide disappearances, which he said defied logical and conventional explanations.
