The Junior Black Mafia: How Teens Became the Most Feared Gang

Dec 11, 2025
A sixteen-year-old stands over a body on a North Philadelphia corner. Summer 1988. The crack era has arrived. And a new generation of killers is about to rewrite the rules of the street. They called themselves the Junior Black Mafia—and they would murder more than forty people in less than four years. This documentary tells the complete story of the JBM, the most violent drug organization in Philadelphia history. These weren't hardened criminals with decades of experience. They were teenagers—some barely out of middle school—who built a murder empire on the crack cocaine trade. They killed rivals before those rivals could become threats. They killed witnesses before they could testify. They killed to send messages, to maintain fear, and eventually, they killed children. The Crawford massacre of August 1990—when JBM soldiers murdered a grandmother and three children in their home—shocked a city that had become numb to drug violence. But by then, the body count was already staggering, and the organization seemed unstoppable. You'll meet Aaron Jones, the young leader who understood that fear was currency and terror was profit. You'll follow Marcus "Champ" Williams, who committed his first murder at seventeen. You'll witness the federal investigation that eventually brought the JBM down—and the informants who risked everything to help. This episode examines what happens when the drug trade falls into the hands of teenagers with nothing to lose. How poverty, hopelessness, and the crack epidemic created perfect conditions for organized murder. And how the methods used to destroy the JBM became templates for fighting gang violence across America. The survivors are still in prison. The dead are still being mourned. And the questions about what created the JBM—and how to prevent the next one—remain unanswered.
