November 8, 1939, while driving his 1939 Lincoln-Zephyr coupe in Chicago. When he left his office at Sportsman's Park racetrack in Cicero, Illinois in the afternoon, he was reportedly carrying a cleaned and oiled Spanish-made .32-caliber semi-automatic pistol, something unusual for him. Two shotgun-wielding gunmen in a dark sedan drove alongside O'Hare as he approached the intersection of Ogden Avenue and Rockwell Street. Both fired a volley of big-game slugs killing O’Hare instantly at the age of 46. His Lincoln crashed into a roadside post while the killers continued eastbound on Ogden Ave and were lost in traffic. No arrests were ever made. In 2010, Chicago alderman Ed Burke asked the Chicago Police Department Cold Case Squad to re-examine O'Hare's murder in light of a new book, Get Capone, which made allegations about the crime. In popular culture In the 2010-2014 HBO series Boardwalk Empire, the character of Mike D'Angelo played by Louis Cancelmi is based on Edward J. O'Hare. In the last season he is shown to be an undercover agent who helped gather evidence to convict Al Capone on Tax evasion. The story of 'Easy Eddie', and his son, are mentioned in the "Payback" chapter of the novel Meg: A Novel of Deep Terror, by American author Steve Alten, published 1996.
