Al Capone was a vicious and notorious mob boss. His career in crime began when he moved to Chicago in 1920. He moved to Chicago with one of his friends in the street gang he was in back in New York. Capone and his friend (Johnny Torrio) went to Chicago to work with a mob boss named Frankie Yale. Frankie was killed and the power was given to Johnny. Later in the years, Johnny retired and gave the crime organization to Al Capone. During Capone's reign, many murders in Chicago were blamed on him, but none of the murders were ever proven. Capone alone murdered dozens of people and ordered the killing of hundreds of others. The most famous murders that were believed to have been ordered by Capone was The Valentine's Day Massacre. Capone ordered "Machine Gun Jack" to murder Chicago's second most vicious mob boss, "Bugs" Moran. The murder was planned to take pace in a meeting in a garage, but Moran was late and seven of Moran's top ten men were killed.
