Cosa Nostra
Salvatore Contorno (; born 28 May 1946), called Totuccio, is a former member of the Sicilian Mafia who turned into a state witness ("pentito") against Cosa Nostra in October 1984, following the example of Tommaso Buscetta. He gave detailed accounts of the inner-workings of the Sicilian Mafia. His testimonies were crucial in the Maxi Trial against the Sicilian Mafia in Palermo and the Pizza Connection trial in New York City in the mid 1980s.
