Jovanović had been a member of the feared Special Operations Unit and held the police rank of lieutenant colonel.

[2] Jovanović was arrested on the charges of being responsible for the assassination of Serbian Prime Minister Zoran Đinđić in March 2003.

The evidence connected him to the infamous Zemun Clan of Serbia's organized crime network, and to its alleged leader, Milorad Ulemek.

[5] He was silent during most of his trial but allegedly, he soon confessed to the murder of Đinđić and said in a police report that he feels no remorse for killing him.

Due to alleged interrogations, beatings and threats against his family, he claims to have been forced to falsely confess.
