Salvatore “Totò” Riina, called “Totò 'u Curtu” (Sicilian for “Totò the Short,” Totò being the diminutive of Salvatore), was an Italian mobster and chief of the Sicilian Mafia, known for a ruthless murder campaign that reached a peak in the early 1990s with the assassinations of Antimafia Commission prosecutors Giovanni Falcone and Paolo Borsellino, resulting in widespread public outcry and a major crackdown by the authorities.
