The Black Mafia is one of the bloodiest, and least known, crime gangs in US history. It was responsible for more than 40 killings, the most chilling being the massacre of two adults and five children in Washington in 1973 in a feud between rival Muslim factions. A heavy round of convictions and jail sentences in the mid- 1980s shattered the Black Mafia's strength - only for their |youth| branch to re-emerge as the Junior Black Mafia. Researched with scores of interviews and unique access to informal logs, witness statements, wiretaps and secret FBI files.
