Cavataio was killed on 10 December 1969 in the Viale Lazio in Palermo as retaliation for the events in 1963 by a Mafia hit squad including Bernardo Provenzano , Calogero Bagarella ( an elder brother of Leoluca Bagarella the brother-in-law of Totò Riina ) , Emanuele D’Agostino of Stefano Bontade ’s Santa Maria di Gesù Family , Gaetano Grado and Damiano Caruso , a soldier of Giuseppe Di Cristina , the Mafia boss of Riesi .
