Maybe this was exactly the reason why he took his life: to save his family. Some radical, pro-Milosevic nationalists probably hated him for his anti-war activities and for representing his country in NATO. In their eyes he committed treason - and he may well have received terrible treaths against his family unless he commits suicide.
Serbian nationals who are now in power don't like NATO. They are against NATO because it bombed Serbia under Milosevic. This ambassador was against Milosevic and is part of NATO. He picks up a delegation of 6 officials, and the ambassador was with his colleaques when he inexplicably "jumps" off the building.
Serbia has a long (and recent) history of treating human life as contingent to nationalist ideology. NATO has had a big role in this recent and bloody history. Serbia want to join EU. The delegation arrives in Brussels. My guess is, other explanations aside, he knew damaging stuff about current figures in the country and was pushing for Serbia to come clean on it as part of EU entry. Others had different ideas...
