His attempt to bribe and intimidate the potential jurors was discovered by Ness's men, The Untouchables. The venire (jury pool) was switched with one from another case, and Capone was stymied. Following a long trial, on October 17 the jury returned a mixed verdict, finding Capone guilty of five counts of tax evasion and failing to file tax returns (the Volstead Act violations were dropped). The judge sentenced him to 11 years imprisonment, at the time the longest tax evasion sentence ever given, along with heavy fines, and liens were filed against his various properties. His appeals of both the conviction and the sentence were denied. One of the Capone properties seized by the federal government was an armored limousine. The limousine was later used to protect President Franklin D. Roosevelt after the attack on Pearl Harbor.
In May 1932, Capone was sent to Atlanta U.S. Penitentiary, but he was able to obtain special privileges. Later, for a short period of time, he was transferred to the Lincoln Heights Jail. He was transferred to Alcatraz on August 11, 1934, which was newly established as a prison on an island off San Francisco. The warden kept tight security and cut off Capone's contact with colleagues.
