In the 1910s, he established an Irish American gang which became one of Chicago's most powerful early organized crime organizations. Murphy's gang was one of the few respected by Al Capone and the Italian American-led Chicago Outfit. A longtime rival of Maurice "Mossy" Enright, Murphy was suspected in his February 1920 gangland slaying. Murphy was released due to lack of evidence. Murphy was involved in a wide array of crimes and arrested and/or indicted numerous times. In February 1921, Murphy was charged with involvement in organizing the theft of $400,000 from a Pullmanmail train at Chicago's Union Station in August 1920. Although he was released on a $30,000 bond, Murphy was eventually convicted and sentenced by Judge Kenesaw Mountain Landis to seven years imprisonment. On May 6, 1922, Murphy, Cornelius Shea, and six other labor leaders were arrested and charged with the murder of a Chicago police officer. On May 24, the state asked for nolle prosequi and the court agreed to withdraw the indictments. A new indictment was returned against Murphy and the others in August, but this second indictment was withdrawn by the state as well. "Big Tim" Murphy was shot and killed as he answered the front door of his home on the night of June 26, 1928.

Others suggest he was killed by Murray "The Camel" Humphreys, a former hitman and later a lieutenant for the Chicago Outfit. Murphy's widow, Margaret, later married mobster John "Dingbat" O'Berta, a Murphy protégé.
