18. The Stryker Brothers

March 3, 1932. It's the great train robbery, on the southbound express headed for Chicago. The Stryker brothers steal mail sacks containing 750 grand in payroll money. During the robbery, a baggage man and Lippy Carson (an associate of the Stryker brothers, who had worked as a mail clerk) are killed, and thrown from the speeding train. Since mail robbery is a federal offense, Eliot Ness and his Untouchables are called in.
