Mafia historian David Critchley identifies the enigmatic Castellammarese War gunman "Buster from Chicago" as Sebastiano Domingo and tracks him back to Berrien County, Michigan. Historians have neglected Berrien's role in the history of the American Mafia. Critchley shows that county's involvement in three major events of the Prohibition Era - the assassination of Antonio Lombardo, the St. Valentine's Day Massacre and the Castellammarese War.
Some underworld legends, often repeated in mob history books and long cherished by Hollywood, will have to be revised or discarded due to continuing discoveries related to a shadowy Prohibition Era Mafia figure named Saverio Pollaccia.
