He must have had money when he died. He became a bitter man and a sore loser. If he had kept out of the spotlight and not written his book and if his son had not written the first book in ht e1960s they may have lived out their lives with more peace. HIs son Bill seems to have become an informer after 1990.
Bill Bonanno was an informant during the war. The FBI had four made members of the Bonanno crime family during the Bananas Split, the only one I have not pinned down on his identity is the New York City member who was against the Bonanno's taking over again.
