He did it because the kid allegedly pinched his buddy's girlfriends ass. The kid that got his ass kicked almost died and went through extensive rehabilitation.
The Serb government tried Kovacevic and found him guilty but he got some ridiculously light sentence. He was paraded around the Serbian Parliament like he was a national hero.
Anyway, there is still an International warrant out for Kovacevic. If he steps out of Serbia and into a country that we have an extradition agreement with he will be brought back here and tried.
