The report effectively exonerated the International Criminal Tribunal for the former Yugoslavia in The Hague of blame over Milosevic's death although it acknowledged security failings in his detention unit.
It found that the ‘unique’ arrangement allowing Milosevic to conduct his own defence had "compromised security" allowing him to get un-prescribed
medicines.
Milosevic, 64, died suddenly March 11 a few months before the expected end of his mammoth trial on war crimes over his role in the bloody conflicts in Bosnia, Croatia and Kosovo that tore apart the Balkans.
He was indicted on more than 60 counts including genocide, war crimes and crimes against humanity, including ethnic cleansing in the war in Bosnia and the 1995 massacre of some 8,000 Muslim men and boys at Srebrenica.
The report, conducted by the tribunal's vice president, Judge Kevin Parker, found that "proper care" was taken in providing Milosevic with medical attention.
"Nothing has been found to support allegations reported in some sections of the media that Mr Milosevic had been murdered, in particular by poisoning," it
said.
Previous reports by Dutch authorities had also found that Milosevic died of a heart attack.
Milosevic's brother rejected the report's findings as "absolutely wrong and incorrect" in an interview with the Interfax news agency in Russia, where he lives.
Borislav Milosevic said the tribunal bore responsibility for his brother's death. "They denied him permission to receive treatment and so deprived him of the right to live," the agency quoted him as saying. "This is like murder."
