Palermo Police Chief Renato Cortese told reporters that members of the Sicilian Passo di Rigano crime clan had settled in the U.S. in the 1980s after surviving a turf war with the Corleone crime clan, which emerged victorious over the Inzerillo crime family in the Palermo area.

Some survivors apparently returned to Italy after the weakening of the long-dominant Corleone crime family. Salvatore "Toto" Riina, the Corleone clan chieftain, died in an Italian prison in 2017.
