His chest had been crushed, and several ribs were broken. Both of his kneecaps had been smashed, likely with a baseball bat.

The 1961 torture-slaying of William "Action" Jackson remains one of the most gruesome chapters in the history of the Chicago Outfit. Jackson, a 300-pound enforcer and loan collector, met a horrific end that served as a brutal warning to anyone considering cooperation with federal authorities.

Jackson ultimately succumbed to his wounds after approximately three days of sustained physical trauma.

The investigation into Jackson's death revealed that he was likely taken to a meatpacking plant on Chicago’s South Side. Mob enforcers, including Fiore "Fifi" Buccieri and James Torello, were suspected of carrying out the torture under the belief that Jackson had "flipped" to the FBI.
