establishing whether the remains belonged to members of the M-19, 265 while the Superior Court of Bogota considered that “there [was] information – fragmented, apparently – that these activities extended not only to the members of the M19, but also to the disappeared, visitors and employees of the cafeteria of the Palace of Justice.” 266 195. In the context of the proceedings against the members of the B-2, the Genetics Laboratory of the Prosecutor General’s Office performed fresh DNA tests on the remains that had been exhumed (supra para. 190), in order to complete the reports prepared in 2001 and 2002. The tests performed in 2010 concluded with the identification of one presumed M-19 guerrilla and one civilian, previously identified by the tests performed by the Universidad Nacional. 267 In June, July and September 2012, tests were also performed, and these proved that other corpses did not belong to the disappeared. At this stage, for the first time, tests were performed with regard to Norma Constanza Esguerra Forero and Irma Franco Pineda. Also, a presumed member of the M-19 was identified. 268 F.4 Investigation into what happened to Carlos Horacio Urán Rojas 196. An investigation into the death of Auxiliary Justice Carlos Horacio Urán Rojas was not undertaken immediately after the events of the taking and retaking of the Palace of Justice. 269 His family received information that he had died inside the Palace of Justice, as a result of crossfire in the building; hence they did not continue their initial inquiries or file a complaint in this regard at the time (infra para. 332). However, on February 1, 2007, during the investigation into forced disappearance, the Fourth Prosecutor found personal documents of Carlos Horacio Urán Rojas in the security vault of the B-2 of the Army’s 13th National Brigade on conducting a judicial inspection of the premises. This finding caused the family to resume its inquiries. 270 Laboratory of the Universidad Nacional de Colombia (evidence file, folio 21689), and report on the results of the bioanthropological analysis of the osseous remains of the holocaust of the Palace of Justice deposited in the Physical Anthropology Laboratory of the Universidad Nacional de Colombia (evidence file, folios 37905 to 37918). 265 Cf.

Cf. Note of the 55th Criminal Circuit Court of Bogota of March 6, 2012 (evidence file, folio 37373). The file before this Court contains three 2010 reports on the examination of the remains of three corpses and, regarding two of them, it is concluded that they belonged to René Francisco Acuña (civilian) and Fabio Becerra Correa (presumed guerrilla). Cf. Report of DNA molecular typing and comparison prepared by the Genetics Laboratory of the Prosecutor General’s Office on February 3, 2010 (evidence file, folios 20649, 20651 and 20654 and 20656), and Report of DNA molecular typing and comparison prepared by the Genetics Laboratory of the Prosecutor General’s Office on March 12, 2010 (evidence file, folio 30942). 268 At this stage, the remains were compared with samples from the next of kin of the disappeared based on the sex of the disappeared family members and the sex attributed to the corpse.
