When Dillinger was finally tracked down and killed, these are the guns the authorities found inside his hotel room:

Besides the Thompson submachine gun, you will also see two sawed off Browning Automatic Shotguns, and two Winchester Semi-automatic rifles.
Dillinger taunted J. Edgar Hoover repeatedly, mailing him cards, and making collect calls to FBI headquarters to chide him.
By the time of Dillinger's death, Hoover was so extremely obsessed with catching Dillinger, that one third of the FBI's total budget was being devoted to his capture. It was a man hunt without equal in our nation's history.
