I can believe that Pisano was there. He was the top lieutenant to Frankie Yale and took part in his assassination. Shortly after that he's with Masseria (clearly Masseria wanted Yale out). Pisano would have been trusted by Masseria. Then a year after Masseria's murder Scarpato was killed too. Sounds like a house cleaning to get rid of Masseria supporters: Giustra, LiConti and Scarpato all killed. Pollaccia killed by Genovese too, in 1932 (obviously with the approval of Luciano).
