Paul "The Waiter" Ricca, was born Felice DeLucia in Naples, Italy. In 1915 he got his first real taste of lawlessness when he killed a man, receiving two years in prison. Later, he left Italy on a ship bound for New York City after having killed the man who testified against him at his trial. Making his way to Chicago, he took up with the Capone Mob. During the proceeding decades, Paul “The Waiter” Ricca would serve as one of the de facto bosses of the outfit.
