Bratunac were bussed in a convoy of 30 vehicles to the Grbavci school in Orahovac early in the morning of 14 July 1995. When they got there, the school gym was already half-filled with prisoners who had been arriving since the early morning hours and within a few hours, the building was completely full. Survivors estimated that there were 2,000 to 2,500 men there, some of them very young and some quite elderly, although the ICTY Prosecution suggested this may have been an over-estimation and that the number of prisoners at this site was probably closer to 1,000. Some prisoners were taken outside and killed. At some point, a witness recalled, General Mladić arrived and told the men: "Well, your government does not want you and I have to take care of you." After being held in the gym for several hours, the men were led out in small groups to the execution fields that afternoon. Each prisoner was blindfolded and given a drink of water as he left the gym. The prisoners were then taken in trucks to the execution fields less than one kilometre away. The men were lined up and shot in the back; those who survived the initial shooting were killed with an extra shot. Two adjacent meadows were used; once one was full of bodies, the executioners moved to the other. While the executions were in progress, the survivors said, earth-moving equipment was digging the graves. A witness who survived the shootings by pretending to be dead, reported that General Mladić drove up in a red car and watched some of the executions. The forensic evidence supports crucial aspects of the survivors' testimony. Both aerial photos show that the ground in Orahovac was disturbed between 5 and 27 July 1995 and again between 7 and 27 September 1995. Two primary mass graves were uncovered in the area and were named Lazete 1 and Lazete 2 by investigators. The Lazete 1 gravesite was exhumed by the ICTY Prosecution between 13 July and 3 August 2000. All of the 130 individuals uncovered, for whom sex could be determined, were male; 138 blindfolds were uncovered in the grave. Identification material for 23 persons, listed as missing following the fall of Srebrenica, was located during the exhumations at this site. The gravesite Lazete 2 was partly exhumed by a joint team from the Office of the Prosecutor and Physicians
