 Contorno received a reduced sentence of six years due to his collaboration with the prosecution.While Buscetta provided important information on the inner-workings of the Mafia, it was Contorno who was more effective as a witness, naming names and explaining the Mafia's heroin trafficking.He testified in a rapid, often incomprehensible specific Palermitan dialect and Mafia jargon that had to be translated for the official record.
