Join Nia and Miles as they explore America's most baffling cold cases, from the Zodiac Killer to JonBenét Ramsey. Discover why these mysteries remain unsolved decades later and how they've shaped our cultural landscape.

Best quote from America's Unsolved Enigmas

Homicide clearance rates have been plummeting since the 1960s—we went from over 90% of cases being solved to barely 50% today. It’s a perfect storm of urbanization, stranger-on-stranger violence, and a shift toward gun violence, which is notoriously harder to crack.
