Stefano Bontade and his brother Giovanni Bontade – who would become a lawyer – studied at a Jesuit college . In 1964 , at the age of 25 , Stefano Bontade became the boss of the Santa Maria di Gesù Mafia Family when his father , '' Don Paolino '' Bontade , stepped down because of ill-health ( he suffered from diabetes ) . The Mafia went through difficult times at that moment . A bloody internal struggle ( known as the First Mafia War ) culminated in the Ciaculli Massacre in June 1963 that killed seven police and military officers sent to defuse a bomb in an abandoned Alfa Romeo Giulietta after an anonymous phone call . 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 . Within a period of ten weeks 1,200 mafiosi were arrested , many of whom would be kept out of circulation for five or six years . The Sicilian Mafia Commission was dissolved and those mafiosi who had escaped arrest went into exile abroad or had to hide out in Italy . In 1968 , 114 went to trial , though only ten minor figures would be convicted of anything . Bontade nonetheless managed to remain a highly important figure within Cosa Nostra , and he was also one of those responsible for ordering the death of Michele Cavataio by sending two of his soldiers , Gaetano Grado and Emanuele D'Agostino , to kill him in the Viale Lazio massacre
