Frank Wallace (died December 22, 1931) was an Irish-American gangster from South Boston, who ran the Gustin Gang during prohibition in Boston. Wallace was the last Irishman to run the illegal rackets in Boston until, agreeing to a "sit down" with Italian mobsters Joseph Lombardi and Phillip Bruccola to resolve the recent hijacking of beer shipments by the Gustins, he and lieutenant Bernard "Dodo" Walsh were ambushed and killed as they entered their rivals' headquarters at the C.K. Importing Company on December 22, 1931.
After this, the Italians were in control until the 1960s, when the Irish gangsters James "Buddy" McLean, Bernard "Bernie" McLaughlin, and the other Irish gang leaders broke away and took over the rackets. For the next 30 years, The Winter Hill Gang would be the top gang of the area.
