The U.S. Treasury Department had been building a tax evasion case against Capone, his brother, and two other gangsters while he was away. He stood trial and on June 16, 1931, pled guilty to tax evasion, telling the judge that he had arranged a deal for a two-and-a-half year sentence only. The presiding judge smirked and informed Capone that he was under no obligation to consider any sort of a prior deal Capone may have made and promptly sentenced him to 11 years in Federal prison. He served seven years, six months and 15 days of that sentence before he was released, his health in severe decline from syphilis he had contracted when he was a much younger man. Although he took treatment for it immediately after leaving prison, he was never the same again. By 1946, he was reduced to the mentality of a 12-year-old child, according to his doctor, and would rant about Bugs Moran, Communists and immigrants. He had a stroke on January 21, 1947, and died from cardiac arrest four days later.
