96 jurisprudence,375 the State must ensure the next of kin of the victims full access and the capacity to take part in all the stages of the investigation and trial of those responsible, pursuant to domestic law and to the American Convention. In addition, the results of the corresponding procedures should be publically disclosed thereby permitting Brazilian society to know the facts of the present case, as well as those responsible.376 2. Determination of the whereabouts of the victims 258. The Commission requested the Court to order Brazil to strengthen, by means of financial and logistical resources, the efforts undertaken in the search and burial of the disappeared victims whose bodily remains have yet to be found and identified. 259. The representatives appreciated the efforts carried out by the State to locate the bodily remains of the disappeared victims in this case, but expressed that the whereabouts and circumstances of the disappearance of these persons is still unknown. They requested the Court to order the State to proceed, immediately, in finding, locating and identifying the victims of this case, ensuring that the guarantees of due diligence be respected, which are essential in the investigation of cases of this magnitude, as well as the impartiality and effectiveness of the procedures. This work must be planned, directed, and effectuated by an interdisciplinary team that is particularly prepared for this task, under the control of judicial authorities, in order to ensure the validity and integrity of the evidence obtained. Likewise, they requested that the State determines the identity of the located bodily remains from the earlier missions made in the Araguaia region and that these bodily remains be delivered quickly to the next of kin upon proof of kinship. The State must cover all the costs, and must respect the traditions and customs of the next of kin of the victims. In addition, they indicated that the consolidation of a bank of DNA samples from the next of kin of the victims is necessary. In particular, regarding the Tocantins Working Group, they stated that it is not an appropriate mechanism to carry out the search for the disappeared persons of the Guerrilla, given that it does not satisfy the abovementioned criteria. 260. The State reported that as of 2006, 13 expeditions were carried out in the Araguaia region with the intention of locating the bodies of the disappeared members of the Guerrilla, some by the next of kin of the disappeared members and others by public institutions. Moreover, the investigations on the possible “Operation Cleansing” are still underway, in which, so as to end the Guerrilha do Araguaia, the soldiers supposedly removed from the terrain all of the bodily remains of the members of the Guerrilla for their subsequent incineration. In particular, on the Tocantins Working Group, the State noted that it was created so as to coordinate and execute the necessary activities in locating, recognizing, and identifying the bodies of the members of the Guerrilla and of the soldiers who died in the Guerrilha do Araguaia. Subsequently, the Interinstitutional Committee for the Oversee of the Tocantins Working Group was created whose note 24, para. 332; Case of Fernández Ortega et al., supra note 53, para. 229, and Case of Rosendo Cantú et al., supra note 45, para. 212. 375 Cf.
