Giuseppe Esposito was the first known Sicilian Mafia member to emigrate to the U.S. He and six other Sicilians fled to New York after murdering the chancellor and a vice chancellor of a Sicilian province and 11 wealthy landowners. He was arrested in new orleans and extradited to Italy.
New Orleans was also the site of the first major Mafia incident in this country. On October 15, 1890, New Orleans Police Superintendent David Hennessey was murdered execution-style. Hundreds of Sicilians were arrested, and 19 were eventually indicted for the murder. An acquittal generated rumors of widespread bribery intimidated witnesses. Outraged citizens of new orleans organized a lynch mob and killed 11 of the 19 defendants. Two were hanged, nine 9 were shot, and the remaining eight were escaped.
The American Mafia has evolved over the years as various gangs assumed, and lost, dominance over the years—for example, the Black Hand gangs around 1900, the Five Points Gang in the 1910s and ‘20s in New York City, and Al Capone’s Syndicate in Chicago in the 1920s. It was not until 1951 that a U.S. Senate committee led by democrat estes kefauver of tennessee determined that a “sinister criminal organization”, later known as la cosa nostra, operated in this nation. Six years later The New York State Police uncovered a meeting of major La Cosa Nostra figures from around the country in the small upstate New York town of Apalachin. Many of the attendees were arrested. The event was the catalyst that changed the way law enforcement battles organized crime.
