Following his indictment, Uwilingiyimana met with ICTR officials a number of times from August to November 2005, and provided information later used in the prosecution of other members of the former régime.
Three months before his death he provided information to Arusha (Tanzania), the seat of the UN Court, which judges all those responsible for the Rwandan genocide.
Uwilingiyimana's confessions allowed him to reduce part of his sentence, according to an agreement he had reached with the court.
[1] In response to his death, ICTR Prosecutor Hassan Bubacar Jallow issued a statement indicating that "this individual, although an indictee of the Tribunal, voluntarily agreed to cooperate in the search for truth and justice for the Rwanda genocide of 1994.
[2] The Chief Investigator of the ICTR, Stephen Rapp, inquired that the last meeting with Uwilingiyimana took place three days before his disappearance.
Defence counsel at the tribunal demanded that Rapp and the two Canadian police officers be suspended and investigated for involvement in the murder but nothing was done.
