Lilo whacking Genovese and Gambino guys left to right seems to be (just like Ivy said) a Mafia urban myth. According to Vinny Teresa, while imprisoned with Lilo, Lilo pointed out some of his drug associates to Teresa and expressed his hate towards them for their stupidity. I don´t remember the exact wording, but Teresa went on to say in his book that Lilo´s associates better watch themselves when released because Lilo was blaming them for getting caught. One of these guys, apparently was Gambino member Joseph LoPiccolo. Although dying a natural death in 1999, LoPiccolo was said for many years (incorrectly) to have been one of those guys murdered by Galante. I think that Teresa´s prison story (and Teresa is now known as having been prone to stretch the truth) may have contributed, at least in some way, to the birth of the myth of Galante killing Gambino and Genovese made guys all over NY.
