After nine long, mysterious and downright thrilling episodes, Unsolved comes to a close with episode 10 titled Unsolved?, wrapping up the revealing series. However, the episode doesn’t open with any familiar faces that viewers have come to know, love or even hate over the previous episodes -- instead, it opens with an unknown motorcyclist getting mowed down by a car and then shot to death in the middle of the street. It’s a cryptic start to what becomes an even more puzzling finale.
After jumping back and forth between Russell Poole’s 1998 investigation and Greg Kading’s 2006 investigation all season long, the two worlds finally collide when Poole requests to meet with Kading to unveil new information about the case. Poole, who hasn’t been an official law enforcement officer in years, is still in hot pursuit of the truth on who killed Biggie and Tupac and how the cases are linked. He claims Death Row’s head of security, Reggie Wright Jr., is the person Kading and the task force need to dial in on. Poole, however, has been physically and mentally worn down by this case and his grandiose conspiracy theories come across as unreliable.
Kading and the task force remain optimistic about their breakthrough with Theresa Swan, the mother of one of Suge Knight's children, who claims she knows who the Biggie shooter is. But after strong-arming her into divulging more information on Biggie’s murder, Theresa claims she doesn’t want to talk at all and won’t “snitch” on Suge. This again leaves them with nothing until they decide to trust Poole’s intel and pay Reggie Wright Jr. a visit. The former Death Row security head maintains his innocence but alludes to Darnell “Poochi” Bolton (Harry Fowler) being rumored to be a hired shooter for Suge. In a quick flash back to the episode’s opening scene, the gunned down motorcyclist appears to have been Poochi himself.
