Other actions. PNC agents, investigators and the Assistant Prosecutor of Mixco Agency No. 5 also went to the scene and contacted the person who lives in the building located beside the lot where the corpse was found. Subsequently, officials of the PNC and the Public Prosecution Service searched the area with negative results, and asked the Criminalistics Bureau to compare the fingerprints in the post-mortem file of the corpse with the database to establish its identity.131 Also, on December 18, 2001, an order was drawn up referring the corpse to the pathologist, but it did not request tests to determine whether the deceased had been sexually abused (supra para. 97). In addition, a site inspection was made and the respective report determined that, the crime scene had been contaminated prior to this inspection (supra footnote 124). The day the body was found, it was reported that several items were confiscated, and were being kept by the Site Inspection Unit.132 102. Cause of death according to the death certificate.
