In January 1999, François Compaoré was charged with the murder of David Ouedraogo, who had died as a result of torture in January 1998. The charges were later dropped by a military tribunal after an appeal. In August 2000, five members of the President's personal security guard detail (''Régiment de la Sécurité Présidentielle'', or RSP) were charged with the murder of Ouedraogo. RSP members Marcel Kafando, Edmond Koama, and Ousseini Yaro, investigated as suspects in the Norbert Zongo assassination, were convicted in the Ouedraogo case and sentenced to lengthy prison terms.
