to find out that Dunbar's real name was Fred Ries. The Intelligence Unit also discovered that he was on the run and was hiding in St. Louis. Wilson rushed to St. Louis and was able to find Ries with help from the postal inspectors. Wilson then arrested Ries and brought him back to Chicago. In Chicago, Wilson got Ries to testify that the cashiers checks represented gambling profits received by Guzik, and his testimony secured Guzik's conviction in late 1930. Intending to have Ries also testify against Capone, Wilson used funds from a group of wealthy Chicago businessmen, known as the "Secret Six," to send Ries on a boat trip to Uruguay and keep him safe until Capone's trial. In the fall of 1930, working late in his office, Wilson discovered a ledger documenting financial records of a very large gambling operation. Every few pages there were calculations of net income that were to be divided to three individuals who were only referred to as A, R, and J in the ledgers. Wilson also found an entry that read:Frank paid $17,500 for Al.This was the best chance that Wilson had come across that linked Capone to income, but he still had to find where the money was being held in order to convince a jury that Capone was without a doubt guilty. Now the goal was to track down the bookkeepers to get them to testify that "A" and "Al" were references to Capone in the ledgers. For over three weeks Wilson evaluated handwriting from every single one of Capone's associates. He checked voter registers, bank deposits, bail bonds certificates, and other documents. Informant E. J. O'Hare helped Wilson identify the bookkeeper as Leslie A. Shumway, who worked at a dog track in Miami. Wilson found Shumway there and persuaded him to testify against Capone. Shumway was to testify that the money was designated to go to Capone between the years of 1924 to 1926, first in front of a grand jury, then again at trial. Around this time, Wilson's team found that between 1927 and 1928 there were monthly wire transfers from Capone to his family in Chicago. It was also found that Capone himself was receiving wire transfers in Miami under an assumed name. This was not just a coincidence as Shumway was tracked down at a dog track in Miami which also happened to be a big
