Unsolved: The Murders of Tupac and The Notorious B.I.G.

In 1997, Detective Russell Poole launches the first major investigation into the murder of The Notorious B.I.G.; ten years later, Detective Greg Kading reopens the still-unsolved case.

Kading and Dupree brief the Biggie Smalls Task Force on the case's popular theories; Poole and Miller travel to Las Vegas to investigate a possible connection between Biggie and Tupac's murders.

Frustrated by their lack of progress, the Task Force questions Kading's leadership; RHD investigates a bank robbery; Biggie warns Tupac about his dangerous new friends.

The Task Force tracks down a person of interest; after Poole gets put on a new case, Miller interviews Biggie's widow; Tupac faces legal trouble and goes to record at Quad Studios in New York.

Poole and Tyndall investigate a dirty cop; the Task Force receives promising results from a ballistics test; Biggie releases "Who Shot Ya," spurring Tupac to make a risky alliance.

The Task Force makes progress on a suspect; Poole continues to be in conflict with Lt. Larson; Biggie and Tupac find themselves at the center of a growing rivalry between their record labels.
