On March 13, 1934, the notorious bank robber John Dillinger and his accomplices, Baby Face Nelson, John Hamilton and Tommy Carroll , attempted to rob the First National Bank owned by YMCA chair, Charles McNider, in Mason City. Dillinger and Hamilton both sustained gunshot wounds during the robbery attempt. Expecting to net some $240,000 from the robbery, they were disappointed to get only $52,000. Dillinger, who had become somewhat of a Robin Hood figured to the public, had planned to use his share of the $240,000 to flee the country. A local legend is that two of Dillinger's gang stayed at the Mason City YMCA two weeks earlier in order to "case the job".
