Infamous Chicago loan shark, known as the most violent in the city's history. Had the basement in his house soundproofed and would bring those unfortunate enough to fall behind in their payments there and inflict sadistic tortures upon them, often resulting in their deaths. In 1973 he was shotgunned to death in his garage. It was widely believed that he was killed by fellow gangster
Tony Spilotro; the two were about to go on trial for murder, and Spilotro was supposedly afraid DeStefano would testify against him.
