Michael Mahoney, better known as Wreck Donovan or simply The Wreck, (fl. 1869–1949) was a nineteenth-century American sneak thief, river pirate and underworld figure in New York City. He was a well-known criminal for hire on the New York waterfront during the post-American Civil War era and later became a member of Patsy Conroy Gang. Mahoney also participated in a number of violent robberies during the early-1870s, including his time leading a group of Fourth Ward railroad thieves, although he usually escaped punishment due to his political connections to Tammany Hall. These activities, however, would lead to his eventual imprisonment by New York District Attorneys Benjamin K. Phelps and Horace Russell in 1873. Biography Michael Mahoney was born in the old Fourth Ward in Manhattan. He began his criminal career while still a young child and became a skilled thief within a few years. He regularly visited the underworld den known as Slaughter-house Point, so named because of the alleged murders that occurred within the establishment, located at the corner of James Slip and Water Street. It was there that he learned his trade from notorious criminal figures such as Johnny Dobbs, Jack Lowry, John McClosky, Soldier Brown and others. By early adulthood, Mahoney had risen from a low-level dock rat to a criminal whose name had "become known to every detective in the country". His portrait (No. 688) was eventually added to the Rogue's Gallery at the Central Office of the New York Police Department. In the years following the American Civil War, Mahoney established himself as a much feared criminal figure on the New York waterfront and eventually recruited by Patsy Conroy to join his gang of river pirates. During this period, Mahoney also worked with Thomas Cummings, Denis Brady, Joe Dollard, Martin Broderick, Sam Lake, John "Johnny the Greek" Keefe and Abe Coakley among others. He and Broderick staged the successful escape of Coakley from the state penitentiary in 1869. From the city-side of the East River, the two men signaled a guard-boat carrying Coakley by waving handkerchiefs. The keeper, believing it was a doctor who wanted the boat, stopped to pick him up. When the boat docked, however, Mahoney and Broderick drew their revolvers and held the guard at gunpoint while Coakley jumped ashore and escaped. Shortly afterwards, Mahoney and Broderick were involved in the robbery of a messenger boy of Stevens Bank in Hoboken, New
