In 1998, Frank Calabrese Jr. makes the most dangerous decision of his life: he writes a letter to the FBI offering to turn against his own father—one of the most feared mob enforcers in Chicago history. What follows is one of the most audacious undercover operations in the history of organized crime.
In this episode, we go inside the moment that changed everything for the Calabrese family and the Chicago Outfit. After being transferred to the same prison as his father, Junior realizes the only way to escape is to cooperate. He offers to wear a wire inside federal prison, hoping to capture Frank Calabrese Sr. incriminating himself in decades of unsolved mob murders.
Told through secret recordings, FBI testimony, and Junior’s own words, this is the story of how one son risked his life to dismantle the family empire he was born into. It’s also the origin of the evidence that would form the heart of the Family Secrets case—the case that brought down the Outfit.

S3 E06: Brotherly Love

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.
Listen to the all new season of Underbelly: Killing Kurt, premiering April 2nd. Available wherever you get your podcasts.
