Sam DeStefano was a Chicago mobster known for torturing his enemies, and those who owed him money. He became the first loan shark in the city's history. Crooked policemen would bring to criminals DeStefano's home and he would put them on a payment plan to pay off their debts. If they missed a payment along the way Mad Sam would take them to a soundproof room in his basement. He used ice picks and broken pool cues to administer vengeance. Perhaps the ultimate in ruthlessness was when Mad Sam and his brother, Mario, willingly killed their own brother, a drug addict. They had been ordered to do so by Sam Giancana.
