 Witness protection proved problematic in the trial.On 29 September 2003, Dragićević, Krsmanović, and Lukić were found guilty of the torture and murder of the abductees; Krsmanović and Lukić were convicted in absentia.On 27 February 1993 members of the Serbian "Avengers" ("Osvetnici") military unit, commanded by Milan Lukić, abducted a group of 19 non-Serb citizens of the Republics of Serbia and Montenegro (18 Bosniaks and one Croat) from the Belgrade-Bar train at Štrpci station near Priboj.
