The Treasure of John Dillinger
At one point in history, Dillinger was the most wanted man. Of all the Depression-era gangsters, he was the one to fear, with a passion for violence that put Bonnie and Clyde and Babyface Nelson to shame. During their reign of terror, Dillinger and his gang were accused of robbing 24 banks, and murdering several police officers. When it came time to apprehend him, he was taken out in a hail of bullets outside the Biograph Theatre in Chicago, but he had absolutely no money on him. In fact, he had supposedly stolen over $200K (which was huge money back then), yet no one knew where it was.
As the legend goes, this money is buried in a suitcase in Wisconsin somewhere, and it was buried 3 weeks prior to his death, when the FBI raided the Little Bohemia roadhouse to apprehend the Dillinger gang. He and his men escaped and it was at this moment that the suitcase went into hiding somewhere in the woods. His plan was to come back in a few weeks, take the money, get plastic surgery and leave the country.
Instead he left this world violently and his money is still out there, buried outside of Mercer, Wisconsin.
