Torrio saw that Capone had potential, with a combination of physical strength and intelligence, and before long was helping Torrio manage his bootlegging business. By mid-1922 Capone ranked as Torrio's number two man and eventually became a full partner in the saloons, gambling houses, and brothels.
Torrio was later forced to leave Chicago after he was shot by rival gang members, and consiequently Capone inherited the "outfit" and became boss. He quickly proved that he was even better at running the business than Torrio and soon he controlled speakeasies, bookie joints, gambling houses, brothels, horse and race tracks, nightclubs, distilleries and breweries. He was reportedly earning an income of 100,000,000 a year.
