The Secret List Hidden in a Floral Diary: The Disappearance of Dawn Mozzino

For twenty years, police believed a convicted predator on death row was the only suspect, ignoring the handwritten evidence sitting in a bedside drawer. Inside a small journal, a devout Catholic woman documented a secret double life involving a married man and a dangerous love triangle. How did investigators miss the names of the men who actually knew her best?

In this episode, we explore the tunnel vision that allowed a cold case to freeze for decades, the tragic loyalty of a boyfriend who still calls her mother every night, and the three specific names written in ink that were never properly investigated. Was Dawn snatched by a stranger, or did she walk willingly toward a betrayal she saw coming? The answer might have been in her room the entire time.
