002/19-09-2007-ECCC-OCIJ ЮŲŠ / No: D427 470. Some of the foreign prisoners detained at S-21 were executed near the S-24 compound. Thus, in 1978, somewhere between Mao Tse Tung Boulevard and the Boeng Tumpung neighbourhood, four foreigners were executed and their bodies burned with tyres on Nuon Chea’s specific instructions, in order to ensure that the bodies would not be found.2034 471. Some of the children who were taken to S-21 were executed on its premises. Young children were generally executed immediately after they were separated from their parents, although some of them were allowed a brief respite before their execution. Duch indicates that Peng, a member of the S-21 staff, was in charge of their execution.2035 472. Four combatants from a military unit, which, as Duch recalls, was referred to by code name Yo8, were also killed during the mass executions which took place on 2 or 3 January 1979. Duch states that these men were killed with a bayonet by the interrogator [REDACTED] on 7 January 1979, and it was their bodies, still chained to beds, that the Vietnamese soldiers discovered when they arrived in S-21.2036 Blood drawing 473. Some S-21 prisoners died after S-21 doctors drew a large quantity of their blood.2037 Duch admits that at least 100 prisoners were killed in this way.2038 Prak Khan states that prisoners were made to lie on their backs on a bed and then their handcuffs were removed, while their feet were shackled and they were blindfolded. A needle was then inserted into their veins and their blood drawn until they died,2039 after which a vehicle took their bodies to Choeng Ek.2040 The blood drawn from the prisoners was then sent to hospitals, and used in particular for transfusions for RAK soldiers who were wounded while fighting Vietnamese forces.2041 474. At first, Duch denied playing any role in the practice of drawing detainees’ blood. He states that if such a method was indeed applied at S-21, it “was a continuation from when Nath was Chairman”.2042 In subsequent hearings, he stated that he could not deny that the blood was drawn from some S-21 prisoners, but maintained that he was never aware of this practice.2043 Finally, before the Trial Chamber, he stated that this practice was instituted on the orders of Son Sen and that it was discontinued once all of the members of the medical team had been executed.2044 *** Extraordinary Chambers in the Courts of Cambodia, National Road 4, Choam Chao, Dangkao Phnom Penh Mailing address: P.O.
