Serge Brammertz said fugitive Augustin Bizimana, who was indicted on 13 charges including genocide, murder and rape, is believed to have died in Pointe Noire, in the Republic of the Congo in 2000. His remains were identified by DNA testing.

Brammertz is prosecutor of a successor U.N. court with dual offices in Arusha, Tanzania and The Hague, Netherlands, that continues to function for remaining suspects and appeals.

“Bizimana was alleged to be responsible for the murders of former Prime Minister Agathe Uwilingiyimana and 10 Belgian United Nations peacekeepers, and for the murder of Tutsi civilians” in five Rwandan regions, Brammertz said in a statement.

The announcement of Bizimana’s death follows the arrest in Paris last week of Felicien Kabuga, another of a handful of prominent suspects from the Rwandan genocide who had been on the run for more than two decades.

“The key lesson from the death of Augustin Bizimana is that the world should give timely justice,” said Naphtal Ahishakiye, executive secretary of genocide survivors’ organisation Ibuka.

“The suspects should be brought to justice before their deaths, also to avoid survivors dying before hearing the cases of those who killed their loved ones.”

The International Criminal Tribunal for Rwanda conducted 50 trials before closing its doors in 2015. Brammertz is prosecutor of a successor U.N. court with dual offices in Arusha, Tanzania and The Hague, Netherlands, that continues to function for remaining suspects and appeals.

The statement said prosecutors had conducted DNA analysis “late last year” on remains that had earlier been recovered from a grave site in Pointe Noire.
