I think it would take a lot of effort to bury a parachute and a body in a forest. Unless he landed in a clearing it's pretty hard to dig due to roots debri etc. Not to mention you would have to be the coolest guy in the world to hide all the evidence and run with the money. I would think he got to a town grabbed a greyhound and disappeared into legend. He's a lot like the Zodiac Killer who eluded capture, who knows maybe it was the same person.
