If we look back at the murder of any LCN boss throughout history, it was perpetrated by members of their own family. I don't think the Masseria hit was any different, plotted and carried out by members of what today is known as the Genovese Family. Look at what happened with the Anastasia hit, everyone thought the Colombos took him out until it was revealed that it was a Gambino hit team. The story of a smorgasbord hit team consisting of such notorious gangster names like Siegle, Genovese, Adonis, and Anastasia etc may sound good, but I don't believe that's how it went down.
