On June 12, 1924, the largest train robbery in U.S. history occurred near here when bandits boarded the train in Chicago and forced postal clerks to surrender sacks containing more than two-million dollars in securities and cash. Local police apprehended the gunmen within a few days, and the U.S. Postal Inspection Service investigated the case and identified the masterminds, one of whom was a trusted employee of the Postal Service. Some of the loot was never recovered, and in all, eight men were convicted in Federal court and sentenced within seven months of the robbery.
