DB Cooper
Somewhere in my pile of books is one on DB Cooper's life after his parachute landing. It seems he injured his ankle upon landing in a forest, buried the cash (a portion of which was dug up by a raccoon and scattered) and found shelter in an isolated cabin where a lady took him in. The author bases his account on the lady's story which was related to him after DB Cooper's demise from natural causes many years later.
The serial numbers had been recorded, but the remaining money was laundered by buying chips at casinos, playing at a few tables and cashing out the chips when leaving.
