34 request of the Public Prosecution Service, the time of death was amended and it was established that “the person had been dead approximately 7 to 11 hours when the autopsy was carried out.146“ 135. The autopsy report contains no photographs or videos, fails to say what clothes the victim was wearing when the external examination was carried out at the morgue, and makes no reference to the fact that the hands were protected with manila paper bags. 147 This fact was documented in the medico-legal expert’s report submitted by the petitioners, based on a review of several documents connected with the case file, including a video of the crime scene in which this fact can be seen. It also stated that the external examination carried out found no evidence to suggest where the alleged victim had died.148 136. Once they established that this was a murder case, the authorities should have preserved specific pieces of evidence in the event rape was suspected, as dictated by the United Nations Manual on the Effective Prevention and Investigation of Extra-Legal, Arbitrary and Summary Executions, 149 especially bearing in mind that the clothes were stained with blood, the brassiere and belt had been removed, and the blouse was on inside-out.150 Although swabs were taken of the alleged victim’s vaginal and anal cavities for analysis, no examination was ordered of the pubic region and no hairs were taken from the clothes. Neither were the alleged victim’s breasts analyzed. In spite of the fact that all the evidence indicated a rape, the autopsy report merely established that the genital organs were “normal.” 151 Furthermore, the enlarged autopsy report stated that “the forensic gynecological examination of the corpse found genitals normal for the age and that she was not a virgin.”152 The analyses of the samples detected the presence of semen in the vaginal swabs.153 146 Appendix 21.
