Castellammarese War
In 1931, when the Castellammarese War between Joseph Masseria and Salvatore Maranzano was taking place, the Los Angeles crime family may have supported Maranzano. Nick Gentile notes in his memoirs that during a conference Maranzano was backed by two men from California. Joseph Bonanno (died 2002) and his son Salvatore Bonanno (died 2008) wrote of several close associates in the Los Angeles area, such as Jimmy Costa (from Castellammare del Golfo), Nick Guastella, Frank Bompensiero and Tony Mirabile.
