Castellammarese War
During the early months of the Castellammarese War, Bonventre became a target as Castellammarese-born members of Schiro's gang began to threaten rival boss Joe Masseria's domination over mafia gangs. Masseria forced Schiro to pay him $10,000 and step down as boss of the gang. Afterwards on July 15, 1930, Bonventre was gunned down outside his garage.
