Al Capone is one of the most notorious gangsters in world history and began his crime spree at a young age. According to the FBI, the gangster joined the street gang after dropping out of school. As time went by, Capone became a big name in the gangster world and became the boss of the Colosimo Mob in Chicago. Subsequently, his activities became more suspicious and the authorities began to investigate him. In June 1931, the gangster was tried for tax evasion and pleaded not guilty. The trial lasted five months and ended with a guilty verdict. As a result, the court sentenced him to 11 years in federal prison.

Between 1929 and 1931, police arrested Al Capone several times on various charges. Although law enforcement put him behind bars for contempt of court in February 1931, they continued to investigate the gangster on charges of tax evasion. Then, in June 1931, Capone initially pleaded guilty to the charges and told the media about the plea deal. The official FBI website noted that Capone had reportedly settled for a two-and-a-half-year prison sentence. However, the judge told him that he was not bound by any plea deal. As a result, Capone changed his plea to not guilty.

The trial ended after five months and the court found Al Capone guilty of tax evasion. According to the FBI, the court sentenced Al Capone to 11 years in prison and sent him to Alcatraz. The gangster spent more than seven years in Alcatraz before being released in November 1939.

According to the FBI, Al Capone was released from Alcatraz on November 16, 1939. HISTORY reported that Capone lived in a nine-by-five-foot cell and was given no privileges.
