He was betrayed to Italian authorities by some of his New Orleans associates. A U.S. private detective firm was hired to locate him and bring him to justice. Private detectives of the Mooney and Boland Agency worked through the New Orleans Chief of Aides Thomas Boylan to arrange the capture.
Esposito's arrest was conducted very much like a kidnapping. The Hennessys caught him alone, grabbed him and threw him into a carriage, taking him off to a secret location. He was prevented from seeing any of his New Orleans family or friends. The following day, he was smuggled aboard a steamship that was already under way for New York City.
The circumstances of his arrest and his New York City efforts to avoid extradition to Italy became international news and the subjects of Congressional inquiries.

Esposito's return to Italy was handled as suddenly as his arrest. Once the U.S. Commissioner was satisfied of his identity and before any legal appeals could be considered, Esposito was turned over to Italian authorities and placed on a ship for Europe. His wife and child were left behind in the U.S. (Esposito trusted New Orleans allies to care for his family. They failed to do so and took Esposito resources for their own benefit. Esposito later tried without luck to sue them from his Italian prison cell. His wife gave birth to a second child after his deportation. Both children were later placed in New Orleans orphanages.)
In his absence, the Crescent City's Sicilian underworld broke apart into warring factions - the competing Provenzano and Matranga organizations.
The Hennessys became instantly famous following the Esposito arrest (though the local police superintendent accused them of insubordination for acting without his approval). Their fame came at a terrible price. Within ten years of Esposito's capture, both of them were murdered. In each case, the killings remained officially unsolved but were widely believed performed by Sicilian gangsters.
David Hennessy became police superintendent in New Orleans and actively fought the local Mafia. As he returned home from work on the evening of Oct. 15, 1890, he was attacked by a group of gunmen. He was knocked down from a distance by a shotgun blast of bird shot and then mortally wounded by higher-caliber slugs fired into his body at closer range. He died the next day. The assassination of the police superintendent resulted in the imprisonment of members and associates of the local Matranga Mafia and later to the Crescent City lynchings.
