Let me summarize again. This is the exact order of events for David Paulides's missing persons grift:
1. Some guy spends his life obsessed with Bigfoot
2. This guy, not getting any traction, switches from Bigfoot to "missing persons" stories. He runs a grift where he researches missing persons stories and then badly distorts them, either leaving out crucial details or inventing new ones, even though many of the cases he discusses were actually solved already or have obvious explanations. He then makes up bullshyt statistics he pulls out of his ass to claim that there are special missing persons "hot spots" that indicate something sinister is happening.
3. Once he gets a big audience for his missing persons work, he switches back to the original grift and connects the missing people to Bigfoot.
So again, in a nation with 330,000,000 people where damn near every fukking square inch is traversed by hikers with cameras on a regular basis, states across America have entire breeding populations of giant man-beasts that are out there stealing people yet NEVER get caught on camera and NEVER leave a body. And while in the 20th century there were numerous supposedly extended, close-up sightings of the creatures, now that literally everyone has a camera on them at all times...we still don't have anything other than blurry-ass photos of trees and monkey suits filled with possum carcasses.
