Wilfred J. Delaney (c. 1937 - August 4, 1964) was an American gangster and member of the McLaughlin Gang who was a friend and associate of Harold Hannon, a contract killer who had murdered boxer Tommy Sullivan in 1957.
Casualties of the McLean-McLaughlin war that claimed dozens in the 1960s, Delaney and Hannon were strangled to death and their corpses were tossed into the Boston Harbor, where they were discovered by longshoremen the following day.
Gang leader Buddy McLean used a female friend as a ruse to set up Wilfred.
When Wilfred and Harold saw McLean with a few of his men in the girl's apartment they tried to escape but were quickly apprehended by the mobsters.
The medical examiner later discovered during the autopsies of both men that the killers had used a butane blow torch and badly burned Hannon's genitals, allegedly to get information from him.
