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).
