After unknown individuals hired Đurović for an unknown fee to kill Pukanić, Đurović, together with brothers Robert and Luka Matanić and Amir Mafalanije, organized accommodation, trailing of Pukanić and the purchase of the necessary equipment, the application states. Đurović decided on the murder method with Željko Milovanović and Bojan Gudurić, who are still at large, and who came to Croatia from abroad for the operation, the application adds. USKOK suspects Đurović of two murders, of Pukanić and his marketing director Niko Franjić, for crimes against general security, and criminal association. He, along with Serbian national Milenko Kuzmanović, was earlier suspected of aiding and abetting the hitmen after the murder. It is believed that they were meant to help the Matanić brothers escape to Serbia with counterfeit documents, but all four were arrested near the Serbian border.
