"He was deprived of the right to treatment and subsequently the right to live," Borislav Milosevic said. "We must call a spade a spade - if a person is denied [medical] treatment than it is murder."
Milosevic, 64, was on trial in the International Tribunal for the Former Yugoslavia on charges of war crimes and genocide when he was found dead in his prison cell March 11.
Borislav Milosevic said the future of The Hague tribunal should be called into question.
"It is high time to raise the issue of the future existence of the international tribunal for the former Yugoslavia," he said. "If an international body does not do what it was formed to do than it loses the legal basis for its existence."
The tribunal rejected Slobodan Milosevic's request to release him temporarily from detention in December 2005 to undergo treatment in Moscow, on the grounds that the former Serb leader would flee the trial.
