Pentito
In September 2002, Giuliano decided to collaborate with the Italian authorities and became a government witness. He cited his willingness to change his life as a reason for his collaboration with the authorities. The former boss revealed many secrets and revealed details which opened several branches of investigation, some of which are still ongoing. The information divulged featured corrupt police officers, corrupt judges, rigged auction houses, and complacent courts. He even made several statements against his former ally, Giuseppe Misso, and revealed specific details regarding the murder of the Vatican's banker Roberto Calvi, who was found hanging from scaffolding beneath Blackfriars Bridge in the financial district of London in 1982.
Luigi Giuliano's collaboration with the Italian authorities was preceded by that of his two brothers, Guglielmo and Raffaele. In retaliation for the defection of the three Giuliano brothers, Nunzio Giuliano was killed by the Camorra during an ambush at the Via Tasso in Naples in 2005, followed by Luigi Giuliano's son Giovanni on December 7, 2006. Giovanni had previously refused to join the Witness Protection program.
