Joe Masseria
During the Castellammarese War, Lansky and Siegel helped Luciano eliminate the "Mustache Petes" and organize the modern American Mafia. Bugsy Siegel (along with Joe Adonis, Albert Anastasia, and Vito Genovese) was reputedly one of the hitmen that shot and killed Joe Masseria on April 15, 1931. Lansky also assisted Luciano with the murder of Salvatore Maranzano by recruiting Jewish hitmen that included Siegel, Red Levine, and Abraham "Bo" Weinberg. On September 10, 1931, Maranzano was shot and stabbed to death in his Manhattan office.
