The indictment alleges that on about 20 November 1991, the JNA and Serb paramilitary soldiers, under the command or supervision of Mrksic, Radic and Sljivancanin, removed about 400 non-Serb individuals from the Vukovar Hospital and then transported around 300 of them to a farm building in Ovcara, where they beat them for several hours. Afterwards, soldiers transported their non-Serb captives in groups of about 10 to 20 to a site between the Ovcara farm and Grabovo, where they shot and otherwise killed at least 264 of them. After the killings, the bodies of the victims were buried by bulldozer in a mass grave at the same location.
Mrksic, Radic and Sljivancanin are charged on the basis of their individual criminal responsibility and their superior criminal responsibility with five counts of crimes against humanity - persecutions on political, racial and religious grounds, extermination, murder, torture, inhumane acts - and on three counts of violation of the laws or customs or war - murder, torture, cruel treatment,
