According to David Paulides, the solution to the Missing 411 mystery is that an ancient enlightened Bigfoot race descended from the Biblical Nephilim who allied with the Nazis during WWII and thus have magical portal technology based on vibrating quartz is secretly abducting high IQ German scientists who are hiking alone in American National Parks for a eugenics-based interspecies breeding program so the Bigfoot-Human hybrid race will be good at building magical shrinking crafts, which they use to fly down wells into the Ogallala Aquifer, which is their version of our Interstate Highway system.

Bigfoots looking for smart white men's sperm to impregnate their Bigfoot women explains this pattern of cases of people going missing in National Parks, according to David Paulides.

According to David Paulides, the people who are found were deemed by the Bigfoots to not be high enough IQ (or perhaps just infertile), so they were unceremoniously dropped back on Earth, usually from a high altitude which kills them during the fall.

This is what Missing 411 is really about. If you don't believe me, listen to investigator Paul Davides who explains it all thoroughly in this video.
