In the 1920s, Ferrigno was a mid-level leader in the Brooklyn crime family of Salvatore "Totò" D'Aquila, the self-proclaimed "Boss of Bosses" of the New York Mafia. Ferrigno was deeply involved in bootlegging, the most lucrative criminal activity during the Prohibition era, as well as illegal gambling, extortion, and prostitution. Labor racketeering became a profitable for all the Italian crime groups in New York. The D'Aquino family's access to the Brooklyn waterfront allowed Ferrigno and his associates to engage in cargo theft, extortion of the dockworkers, and exercise control over the longshoremen's unions.
Rise to power
In 1928, D'Aquila was murdered on the orders of rival Manhattan Mafia Boss Giuseppe "Joe the Boss" Masseria. Ferrigno and Mineo had been business associates and allies of Masseria; it is possible they conspired with him to eliminate D'Aquila so they could become the new gang leaders. Whatever the exact circumstances, Masseria needed to place loyal supporters in D'Aquila's stead, and he therefore gave his support to Mineo and Ferrigno. In late 1928, Mineo became the boss and Ferrigno the underboss of the old D'Aquila gang. The two men controlled approximately 400 to 500 Mafia soldiers with their most lucrative criminal interests in Brooklyn and Manhattan. After bootlegging, illegal gambling on horse races, numbers rackets, and the Italian lottery were the biggest money makers for the gang. In 1931, this gang was incorporated into the Mangano crime family, later to be called the Gambino crime family.
Castellammarese War
While Ferrigno ran his criminal activities, a group of Sicilian mafiosi from Castellammare del Golfo led by Salvatore Maranzano began to challenge the authority of Ferrigno's benefactor, Masseria. Once the conflict known as the Castellammarese War officially broke out into open warfare by early 1930, there were deaths throughout America's Italian underworld.
Death
On November 4, 1930, a meeting of Masseria supporters was held in Ferrigno's Bronx apartment at 759 Pelham Parkway South. In attendance were believed to be a number of top Masseria and Mineo crime family members, including Mineo, Charlie "Lucky" Luciano, Vito Genovese, Masseria, and Ferrigno himself. Maranzano faction members including Joe Profaci, Nick Capuzzi, Joe Valachi and a hitman known only as Buster from Chicago were observing the meeting from an apartment Valachi had rented across the courtyard. According to Valachi, in the night of November 5, 1930, Steve Ferrigno and Al Mineo left the apartment and walked across the courtyard, and the Maranzano men mowed them down with gunfire. Many organized crime historians and even a former Mafia boss, Joseph Bonanno dispute Valachi's claim that a top boss such as Joe Profaci would be directly involved in the assassination of an underworld rival. Masseria was killed in a Coney Island restaurant in early 1931, and Maranzano was himself killed in September, marking the end of the Castellammarese War. The main beneficiary was Charlie "Lucky" Luciano, who established himself at the top of the New York Mafia. Ferrigno was buried in Calvary Cemetery in Woodside, Queens.
