 The Grecos suspected Salvatore and Angelo La Barbera of the attack, although the one behind it was in fact another mafioso, Michele Cavataio, as he tried to pit the Grecos and La Barberas against one another for his own goals.On January 17, 1963, Salvatore La Barbera disappeared and was never heard of again.Angelo La Barbera also disappeared, but two weeks later he reappeared in Milan, in the north of Italy, giving a press conference.
