On August 7, 1996, 6-year-old Katherine Korzilius vanished while walking home in her quiet Austin neighborhood. She was later found unconscious on the road with a fatal head injury—and died that evening. Authorities ruled out a typical hit-and-run and considered theories including a fall from a vehicle or possible abduction. Her family believes she was placed where she was found, and rejects the idea of an accident.
Despite multiple leads—including scent tracking dogs and medical examiner findings—the case remains unsolved. Katherine’s father, Bon Jovi’s longtime manager, honored her memory with the song “August 7, 4:15.”
Watch as Detective Ken Mains breaks down the evidence, explores every theory, and asks: was this a tragic accident or something more sinister?
