Alberto Clemente arrived in Empire Bay, United States in 1926 and through his uncle began making big money smuggling alcohol during the prohibition. In 1929 he was approved by the commission to start his own crime family.
Although powerful, Clemente's crime family is seen as second-rate by other criminals in the city and his decisions are controversial even by mob standards, which includes him charging $5000 dollars to induct someone into his family. He runs Freddy's Bar in the Little Italy district, and also has his own slaughterhouse located on the outskirts of the city.
In 1945 he ordered the hit on a rival mobster known as the "Fatman", with the task being carried out by Clemente family soldato Henry Tomasino, and associates Joe Barbaro and Vito Scaletta. Shortly after Vito was arrested for stealing and distributing gas stamps for the family and got sentenced to ten years in prison. When Joe berated capo Luca Gurino over the incident, a hit was put out on Joe resulting in him fleeing Empire Bay.
In 1951 Clemente began muscling in on Falcone's drug operations and wanting a piece of the action. Seeing Clemente as a threat, Falcone put a hit out on him and sent both Vito and Joe (now soldiers for the Falcones) to do the job. Clemente rented a hotel in order to have a sit down with his men. Vito and Joe managed to sneak inside and wire the board room with a bomb and detonated it, but just prior to it Clemente took a bathroom break. Seeing the boardroom in destruction, Clemente fled. Vito and Joe chased down Clemente's car which later crashed. Approaching the window, Joe riddled an injured Clemente with bullets, killing him instantly.
