DB Cooper
In 2016, the FBI formally concluded its inquiry into DB Cooper's disappearance. That was 45 years after he stole $200,000 and fled with a jet. Cooper jumped out of the plane carrying the cash and was never heard from again.
DB Cooper was a pseudonym. Nobody is entirely sure who the individual was or what happened to his money, which is now worth more than $1 million. The narrative has been the subject of books and films. Various claims claimed he was either alive or dead. Since a youngster discovered $5,800 of it in the Columbia River in 1980, some people believe that the money is still out there in the wild.
New evidence and clues in the case have been found up till 2020. Of course, they weren't huge ones, but the destiny of the enigmatic and bold burglar still intrigues people.
