a special agreement had been achieved between Cosa Nostra and "some foreigners" for the elimination of Mattei which was organized by Giuseppe Di Cristina. These statements triggered new inquiries, including the exhumation of Mattei's corpse. First Mafia War "Ciaschiteddu" Greco was one of the protagonists in a bloody Mafia war between rival clans in Palermo in the early 1960s – known as the First Mafia War, a second started in the early 1980s –, for the control of the profitable opportunities brought about by rapid urban growth and the illicit heroin trade to North America. The conflict was sparked by a quarrel over an underweight shipment of heroin and the murder of Calcedonio Di Pisa – an ally of the Grecos – in December 1962. The Grecos suspected the brothers Salvatore and Angelo La Barbera of the attack. Salvatore La Barbera disappeared on the 17th of January, and the police suspected Greco of ordering the murder. Many mafiosi from both the Greco and La Barbera sides were killed in the conflict, but it was later discovered that the war was in fact started by Michele Cavataio, who was hostile to both Grecos and La Barbera and successfully pitted them against one another for his own goals. On 30 June 1963 a car bomb exploded near Greco's house in Ciaculli, killing seven police and military officers sent to defuse it after an anonymous phone call. The outrage over the Ciaculli Massacre changed the Mafia war into a war against the Mafia. It prompted the first concerted anti-mafia efforts by the state in post-war Italy. The Sicilian Mafia Commission was dissolved and of those mafiosi who had escaped arrest many went abroad. "Ciaschiteddu" Greco fled to Caracas in Venezuela. The repression caused by the Ciaculli Massacre disarranged the Sicilian heroin trade to the United States. Mafiosi were banned, arrested and incarcerated. Control over the trade fell into the hands of a few fugitives: the Greco cousins, Pietro Davì, Tommaso Buscetta and Gaetano Badalamenti. On 22 December 1968, "Ciaschiteddu" Greco was sentenced in absentia to four years in prison at the trial against "the 114" in Catanzaro that was a consequence of the Ciaculli Massacre. In the appeal he was acquitted. In 1973 he received the maximum period of five years of internal banishment at the remote island of Asinara, but he was nowhere to be found.
