He also operated for several years in the United States. He is often depicted as the "boss of bosses", although such a position does not exist in the loose structure of Cosa Nostra in Sicily. [END] 
[1]  [DOC] 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. [END]
