This chapter investigates how de facto international prosecutors, including those inspired by the indictment against Pinochet, played an essential role in extending the reaches of international criminal law to Hissène Habré, former president of Chad. Indeed, Habré was later referred to as the ‘African Pinochet’.1 Both local and international private non-State actors drew upon the lessons learned from the ‘Pinochet precedent’,2 as well as the Nuremberg Tribunal, and implicitly attempted to adapt and innovate practical tasks and processes ordinarily associated with offices of international prosecutors. As in the previous chapter, witnesses and victims of cores crimes played an essential role as de facto international prosecutors. This chapter begins with Souleymane Guengueng, a victim and witness to core crimes perpetrated under Habré’s dictatorship. It explores how and why Guengueng, and other victims of Habré’s violent repression were instrumental in initiating an investigation into Habré. Unlike Juan Garcés, Souleymane Guengueng never studied law or politics.
