For decades, Kurt Calabrese lived in the shadow of his father, Frank “The Breeze” Calabrese Sr., one of the Chicago Outfit’s most feared hitmen and loan sharks. Raised in a home ruled by violence, paranoia, and control, Kurt grew up knowing that loyalty wasn’t a choice, it was survival.

In 2007, the Family Secrets Trial exposed 18 unsolved murders and a laundry list of heinous crimes that had terrorized Chicago for decades. Based on wiretap evidence from Kurt’s brother Junior, the case led to life sentences for some of the most powerful mob figures in modern history, effectively dismantling the Chicago Outfit. But the trial was just the public reckoning. The real story began years earlier, inside the Calabrese family itself. Season 3 of the award-winning podcast Underbelly, “Killing Kurt” takes listeners back to where it all began.

Beyond the headlines and the courtroom, this is the story of a crime family at war with itself. As Kurt wrestled with his own loyalty, his older brother committed the ultimate betrayal, setting off a chain of events that would not only take down their father but leave Kurt caught in the crossfire.

Told through his firsthand account, Kurt reveals the untold cost of growing up in the mob, the violence at home, the psychological toll, and the impossible choices made to escape a legacy of fear.
