By the late 1920s, Lansky and Siegel had ties to Luciano and Frank Costello, future bosses of the Genovese crime family. Siegel, Albert Anastasia, Vito Genovese, and Joe Adonis allegedly were the four gunmen who shot New York mob boss Joe Masseria to death on Luciano's orders on April 15, 1931, ending the Castellammarese War. On September 10 of that year, Luciano hired four gunmen from the Bugs and Meyer Mob (some sources identify Siegel as being one of the gunmen) to murder Salvatore Maranzano in his New York office, establishing Luciano's rise to the top of the Mafia and marking the beginning of modern American organized crime.
