The Tribunal confirmed that preliminary results of blood tests shows there is no indication that Milošević's death by heart attack was caused by poisoning. Judge Fausto Pocar, president of the UN war crimes tribunal, told a news conference: "So far no indications of poisoning have been found. I would like to stress that these are provisional results." Tribunal registrar Hans Holthuis confirmed that traces of rifampicin were found in an earlier 12 January blood test. However, Pocar said that there are no traces of the drug were found at the time of Milošević's death. According to The Hague, district public prosecutor Moraal, referring to the NFI/Dutch Forensic Institute, "rifampicin disappears from the body quickly, and the fact that no traces were found implies only that it is not likely that rifampicin had been ingested or administered in the last few days before death".
