According to Vizzini 's own account , '' La Verità sui Fatti di Villalba '' ( The Truth About the Events in Villalba ) that appeared in separatist newspapers , it had been the Communist who had started the shooting . When Pantaleone and Li Causi had arrived in the town , they asked Vizzini if they were in hostile territory and whether their meeting might be disturbed . Vizzini " assured them that they were free to hold their meeting without any fear of disturbance if they were careful enough not to speak on local matters " . Vizzini admitted that he interrupted Li Causi , but denied that he had ignited the violence . The Carabinieri quickly restored order and arrested eight people , including the mayor . Several others , including Vizzini , evaded the police dragnet . Sixty persons were interrogated , but the investigation was doomed from the start . ( Don Calò and his bodyguard were accused of attempted manslaughter . The trial dragged on until 1958 , but by 1946 the evidence had already disappeared . Vizzini was never convicted because by the time of the verdict he was already dead . ) The Villalba attack inaugurated a long series of Mafia attacks in Sicily on political activists , trade union leaders and ordinary peasants resisting Mafia rule . In the following years , many left-wing leaders were killed or otherwise attacked , culminating in the killing of 11 people and the wounding of over thirty at a May 1 labour parade in Portella della Ginestra . The Portella della Ginestra massacre was attributed to the bandit and separatist leader Salvatore Giuliano . Nevertheless , the Mafia was suspected of involvement in the bloodbath and many other attacks on left-wing organisations and leaders
