ACHIEVEMENTS: More than 160 ethnic Serbs, Croats and Muslims indicted over past 11 years, mostly ethnic Serbs. COMPLETED CASES: Of the completed cases, 40 suspects were found guilty, six not guilty and four were transferred to Balkan states for trial. Indictments were dropped against 25 suspects. CONVICTS: Top convicts include former Bosnian Serb President Biljana Plavsic, serving an 11-year sentence, and Gen. Radislav Krstic, serving a 35-year prison term for aiding and abetting genocide in Srebrenica, Bosnia, in 1995. Goran Jelisic, who called himself the "Serb Adolf," is serving 40 years. The only life sentence was issued against Milomir Stakic, who is appealing. AT LARGE: Six indictees are still at large, including former Bosnian Serb political leader Radovan Karadzic and Gen. Ratko Mladic, accused of genocide for Srebrenica.
