[1][2] In the night of 2 February 1992, Yugoslav People's Army conscript Drago Miličić, 20, got drunk in a cafe in Modran, where he smashed several ashtrays with a knife before returning to his barracks.
There, he seized a rifle and shot his commander and two privates as they slept.
He then threw grenades at security posts, stole a car, and returned to Modran, where he shot his girlfriend's mother, her father, and her brother.
During a medical examination before conscription, the psychiatrist noted that he was emotionally immature, and that he had an anxiety-depression disorder, but that this was not a sufficient reason to prevent his enrollment in the army.
Lieutenant Dragoslav Radovanovic, Miličić's superior and subsequent victim, had tried in early October 1991 to inform his superiors that Miličić should be released due to mental issues.
