Castellammarese War
After Mineo's death, Francesco "Frank" Scalice became crime family boss. He immediately switched allegiance from Masseria to Maranzano, who was emerging as the winner in the gang war. It has been theorized that Scalise had arranged a secret deal with Maranzano to kill Mineo and become the organization boss, but Maranzano forces were able to eliminate Mineo without Scalise's help. On April 15, 1931, Joe Masseria was shot and killed in a Coney Island restaurant and the Castellammarese War was over.
