John M. "Cockeye" Dunn (August 24, 1910 – July 7, 1949 Ossining, New York) was a New York mobster who was involved in the numbers racket and labor racketeering as a top enforcer for his brother-in-law, Eddie McGrath. He was convicted, together with Andrew "Squint" Sheridan, of the 1947 murder of Greenwich Village hiring stevedore Anthony "Andy" Hintz, and executed by electric chair on July 7, 1949, aged 38. Early life John M. Dunn was the first child born to Irish emigrant parents, Tom and Kitty Dunn, who left Ireland in the early 1900s and settled in Queens, New York City, New York. He was in and out of Catholic reform schools after the death of his father, a sailor in the Merchant Marine who was lost at sea when Dunn was four. Criminal career With arrests for robbery and assault during his teenage years, Dunn was finally convicted of robbing a card game and sentenced to two years imprisonment at Sing Sing Prison. Following his release, Dunn was hired as an enforcer for McGrath who was then a part owner of Varick Enterprises, a front company which made collections for the waterfront dock bosses of Manhattan's West Side. In 1937, he and McGrath were arrested in connection with the death of a trucker but the charges were eventually dismissed for lack of evidence. Later he formed a labor union (Local 21510, Motor and Bus Terminal Checkers, Platform and Office Workers) associated with the American Federation of Labor (AFL) and eventually oversaw waterfront racketeering on Manhattan's Lower West Side by the early 1940s. He established underworld connections including Joseph P. Ryan, who had sponsored him for union membership, and Meyer Lansky who had been in discussions regarding the use of the longshoremen's union to assist in the importation of heroin and cocaine into the United States. The Hintz case At 7:40 a.m. on January 8, 1947, Andrew "Andy" Hintz, hiring boss on Pier Fifty-One, was shot six times on the stairs just outside his apartment when leaving for work. He survived the attack and was taken to St. Vincent's Hospital, where he drifted in and out of consciousness for three weeks before his death on January 29. Before having been taken to the hospital he had told his wife that he had been shot by John Dunn. Dunn was arrested immediately and held as a material witness. On January 11,
