In 1916 the Camorra had assassinated Nicholas Morello, head of the Morello gang. In response, D'Aquila allied with the Morellos to fight the Camorra. In 1917, both Morano and Vollero were convicted of murder and sentenced to life in prison. With their leadership gone, the two Camorra gangs disappeared and D'Aquila and the Schiro family in Brooklyn took over many of their rackets in Brooklyn. Soon after, D'Aquila absorbed the Mineo gang, making Mineo his first lieutenant. D'Aquila now controlled the largest and most influential Italian gang in New York City. It was about this time that Joe Masseria, another former Morello captain, began asserting his influence over the Lower East Side's Little Italy and began to come into conflict with D'Aquila's operations there, as Prohibition approached.
