March 28 – Pietro Aglieri writes a letter to the National Anti-mafia Prosecutor, Pierluigi Vigna, and the Chief Prosecutor of Palermo, Pietro Grasso to ask for negotiations. His proposal is that mafiosi would get more lenient penalties in return for recognizing the existence of Cosa Nostra and the authority of the Italian state. Aglieri had been approached by Vigna in 2000 in an attempt to get mafiosi to "dissociate" from Cosa Nostra — without becoming collaborators of justice — a method that was used successfully in the struggle against the Red Brigades. Ex-Red Brigades members could publicly recognise their errors without having to admit their own criminal responsibilities.
April 16 – Arrest of Antonino Giuffrè. He started feeding investigators information even before he agreed to turn state' witness in June, 2002. He is one of the most important mafia turncoats since Tommaso Buscetta in 1984. His collaboration has updated investigators' knowledge and provided a new interpretation for the sensitive issue of Cosa Nostra's relations with politics in the early 1990s. Apparently the arrest of Giuffrè was made possible by an anonymous phone call that seems to have been made by loyalists to the Mafia hardliners Totò Riina and Leoluca Bagarella. The purpose was to send a message to Bernardo Provenzano. The incarcerated bosses want something to be done about the harsh prison conditions – and were believed to orchestrate a return to violence while serving multiple life sentences.
