 Cavataio claimed to have drawn a map of the Palermo Mafia families including the names of all members in an attempt to blackmail his way out of trouble.Such a map was dangerous if the police would get a hand on it.Cavataio and three of his men were killed on 10 December 1969 in the Viale Lazio – a modern street in the smart new northern area of Palermo – 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 and Gaetano Grado of Stefano Bontade's Santa Maria di Gesù Family, and Damiano Caruso, a soldier of Giuseppe Di Cristina, the Mafia boss of Riesi.
