Salvatore Leone is a character from the Grand Theft Auto series of games. He was born in Palermo, Sicily, in 1935 and would eventually become the leader, Don, of the Leone mafia family. He would become one-third owner of the Caligula's Casino in Las Venturas and it was around this time that he met Carl Johnson. Of course, CJ was working with the Triads and would eventually "betray" Salvatore, which most likely led to his departure from San Andreas and to Liberty City.
During the events of Grand Theft Auto: Liberty City Stories, he is at war with the Sindacco and Forelli families, as well as new threats, the Triads and Diablos. Although he tried to get Donald Love into office as mayor, Love lost to Miles O'Donovan and eventually, Salvatore was arrested and put on trial because of all of the crime in the city. He would win all of these trials.
It was in Grand Theft Auto III that Salvatore's story continues. It is during this time that he meets Claude, who first started working for Luigi Goterelli, someone who works for Leone. However, Maria Latore, Salvatore's wife, says she has a relationship going with Claude, which makes him try and kill Claude. Later on in the game, he is killed by Claude, who has orders from Asuka Kasen.
