"Nothing has been found to support allegations reported in some sections of the media that Mr. Milosevic had been murdered, in particular by poisoning," the tribunal said in an internal report on the circumstances surrounding Milosevic's death.
The former Yugoslav president died in his cell in the tribunal's detention unit on 11 March during a marathon trial for war crimes committed in the former Yugoslavia in the 1990s.
An investigation conducted by Dutch judge K. H. Parker concluded in April that Milosevic had died of a heart attack and that toxicological tests had revealed no traces of any poison or substance that might have caused the heart attack.
Milosevic's family, however, blamed the tribunal for his death because it had denied him permission to undergo medical treatment in Russia. Milosevic's lawyer said that his client had written a letter to Russian officials the day before his death saying he feared he was being poisoned.
"On occasions (Milosevic) refused to accept advice to take medications, or varied the prescribed dosage, refused to undergo recommended tests, and administered to himself medications which had not been prescribed by his treating doctors," the report says.
After Milosevic was allowed to present his own defence, the tribunal assigned him a privileged room with a telephone and a computer where he could meet his lawyers and witnesses. A Russian witness admitted having smuggled medications into the detention unit.
The report also says that Milosevic was not fit to represent himself, and that medical specialists differed in their opinion as to whether a surgical intervention would have prevented his death.
