According to Albert Fried's "The Rise and Fall of the Jewish Gangster in America," the hit squad that dispatched Masseria consisted of Albert Anastasia, Vito Genovese, Joe Adonis and Bugsy Siegel. I read elsewhere that Abraham (Bo) Weinberg, Dutch Schultz's chief gunsel, may have participated. Charlie Luciano set it up, but went to the men's room when the shooters entered.
