High Quality Content by WIKIPEDIA articles! Salvatore Vincent "Bill" Bonanno (November 5, 1932 – January 1, 2008) was the son of Cosa Nostra boss Joseph Bonanno. Although his father never intended for him to be the underboss of the Bonanno crime family, his appointment to high positions in the syndicate precipitated a "mob war" which led to the Bonanno family`s exile to Arizona. Later in life, he became a writer and produced films for television about his family.
