On 12 July 1995, as the day wore on, the refugees in the compound could see VRS members setting houses and haystacks on fire. Throughout the afternoon, Serb soldiers mingled in the crowd and summary executions of men occurred. In the late morning of 12 July a witness saw a pile of 20 to 30 bodies heaped up behind the Transport Building in Potočari, alongside a tractor-like machine. Another testified that he saw a soldier slay a child with a knife in the middle of a crowd of expellees. He also said that he saw Serb soldiers execute more than a hundred Bosniak Muslim men in the area behind the Zinc Factory and then load their bodies onto a truck, although the number and nature of the murders stand in contrast to other evidence in the Trial Record, which indicates that the killings in Potočari were sporadic in nature. Soldiers were picking people out of the crowd and taking them away. A witness recounted how three brothers—one merely a child and the others in their teens—were taken out in the night. When the boys' mother went looking for them, she found them stark naked and with their throats slit. That night, a Dutchbat medical orderly witnessed two Serb soldiers raping a young woman.
