Tommaso Buscetta (July 13, 1928 - April 2, 2000) was an Italian mafioso, and later repented.

Italian Mafia turncoat was first in the Italian pentiti witness protection program.

His testimony in the New York “pizza connection” trial in the mid-1980s allowed the conviction of hundreds of mobsters in Italy and the United States.

In Italy he helped the judges Giovanni Falcone and Paolo Borsellino to achieve significant successes in the fight against organised crime (the two judges were later both killed by Mafia).
