The Viale Lazio massacre on 10 December 1969 was a settling of accounts in the Sicilian Mafia. Mafia boss Michele Cavataio and three men were killed in the Viale Lazio in Palermo, Sicily, by a Mafia hit squad. The bloodbath marked the end of a pax mafiosa that had reigned since the Ciaculli massacre until the end of the Trial of the 114 against Cosa Nostra.
