Which "boss of bosses" Mafia member was behind the murder of New York City police sergeant Joseph Petrosino?
Enrico Alfano Enrico Alfano (born 1869 or 1870; date of death unknown), also known as "Erricone", was considered to be one of the chiefs of the Camorra, a Mafia-type organisation in the region of Campania and its capital Naples in Italy, at the turn of the 20th century. He was described as "a kind of president of the confederation." According to some sources, Alfano was the man behind the murder of New York City police sergeant Joseph Petrosino in Palermo in 1909. However, the murder has since been attributed to the Sicilian Mafia, and to Vito Cascioferro in particular.
Salvatore Bonanno 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.
