In 1930, the Castellammarese War started between Masseria and Salvatore Maranzano, the new leader of Cola Schirò's Castellammarese gang, for control of Italian-American organized crime in New York. Mineo was a casualty; he and Ferrigno were shot dead during an assassination attempt on Masseria on November 5, 1930. In April 1931, Masseria was murdered in a restaurant by several of his gang members who had defected to Maranzano. Maranzano declared himself the boss of all bosses and reorganized all the New York gangs into five crime families. Maranzano appointed Frank Scalice as head of the old D'Aquila/Mineo gang, now designated as one of New York's new five families.
