after the gassings stopped, but the gravedigger, a Serb named Vladimir Milutinović, survived. "Eighty-one or eighty-two trenches were prepared and I helped dig all of them," he recalled. "At least 100 people [fit] into each trench [...] These ones were only for those suffocated in the truck. We dug a different set for those who were shot." Few inmates remained in the camp after the gassings stopped, mostly non-Jewish women who had been married to Jews. They were released several days later, after being sworn to secrecy. Apart from Sajmište inmates, the 500 patients and staff of the Belgrade Jewish Hospital, as well as Jewish prisoners from the nearby Banjica concentration camp, were also killed in the gas van. The last Jewish prisoner in Sajmište was killed on 8 May 1942, and the gas van used at the camp was returned to Berlin on 9 June 1942. It received a technical upgrade there, and was then transferred to Belarus where it was used to gas Jews in Minsk. Shortly after leading the extermination of the Jewish inmates in Sajmište, Andorfer and Enge were assigned different Security Police roles. Andorfer later received an Iron Cross 2nd Class for running the camp, and won a promotion.

Conditions deteriorated to such an extent that some began comparing it to Jasenovac and other large concentration camps throughout Europe. The camp became the main transit point for Yugoslav prisoners and detainees on their way to labour locations and concentration camps in Germany. An estimated 32,000 mostly Serb prisoners passed through Sajmište during this period, 10,600 of whom were killed or died due to hunger and disease. Alarmed by the fact that the campgrounds could easily be seen from across the Sava, in late 1943, the new German ambassador to Serbia proposed that the camp be moved deeper into NDH territory, because its "[continuing existence] before the eyes of the people of Belgrade was politically intolerable for reasons
