State Violence in Chad: A statistical analysis of reported prison mortality in Chad's DDS prisons

This report documents the death of prisoners inside Chad's Direction de la Documentation et de la Securite (DDS) prisons between 1982 and 1990, and the extent to which former Chadian president Hissene Habre and senior officials within his government are responsible for human rights violations committed by the DDS. The report presents evidence which is consistent with the hypothesis that the policies and practices of Hissene Habre and senior DDS officials, whom Habre appointed, contributed to deaths in custody on a level substantially higher than the adult mortality rate of Chad at the time. The analysis tests the hypotheses that Habre had a superior-subordinate relationship with senior DDS officials and had knowledge of their actions, which resulted in substantial deaths in custody.
