After the Civil War, the Reno brothers returned to Rockford, Indiana, with a number of thieves and questionable characters, and their gang soon carried out far-reaching crime sprees that included train robbery, theft, and murder. On the night of October 6, 1866, gang members John and Simeon Reno, along with Frank Sparks, boarded an O&M train near here and took $12,000 to $18,000 from an Adams Express Company safe, committing the first moving train robbery in the United States. The Pinkerton Detective Agency was soon asked to search for the thieves, but only after the gang's last and most profitable train robbery at Marshfield, Indiana, did the tide begin to turn. During July 1868, on two separate occasions, hooded members of the Jackson County Vigilance Committee overpowered armed guards just west of Seymour and took a total of six gang members to a nearby beech tree to hang. In the early morning of December 12, 1868, vigilantes forcibly entered the New Albany, Indiana, jail and dragged brothers Frank, William, and Simeon Reno, along with fellow gang member Charlie Anderson, from their cells and hanged them from the jail rafters. The hangings caused a public outcry and an international crisis and prompted an investigation, but there were no arrests, and the identity of the vigilantes remains a mystery. The brothers are buried at the Old Seymour City Cemetery.
