representatives must be presented to the Court to be considered within the procedure of monitoring compliance with this Judgment. 269. Furthermore, in light of the gravity of the facts of the instant case, the Court finds it necessary, as it has in another case relating to Guatemala,344 that the State implement, through the institutions that it considers suitable for this purpose, within one year, a genetic information bank to safeguard the information, on the one hand, of the osseous remains that are found and exhumed and, on the other, of the next of kin of the persons who were presumably executed or disappeared during the acts perpetrated in the context of the massacres of the community of Río Negro. The purpose of this measure is that the samples and information collected can be compared in order to identify who the remains belong to. In this regard, the Court finds it necessary to stipulate that, to this end, the prior and informed consent of the members of the community of Río Negro who wish to provide samples of genetic material for this purpose is required. The State must assign the human, financial, logistic and other resources required to ensure that the design, implementation and functioning of the genetic information bank are carried out adequately and comply with the purpose for which they are ordered by this Court. 270. The mortal remains of the victims in this case must be returned to their next of kin, following reliable authentication of their identity and relationship, if possible, through DNA testing, as soon as possible, and without any cost to the next of kin. In addition, the State must cover the funeral costs, in agreement with the next of kin of the deceased person,345 respecting their beliefs.346 271. The State must conclude all the exhumations within four years from notification of this Judgment. If the remains of any victim in this case are not claimed by their next of kin within two years, calculated from the date on which the representatives, or the next of kin directly, are informed of their location, individualization and identification, the State must bury those remains individually in a place agreed with the representatives and put on record that they are unclaimed remains of those who died as a result of the facts of the instant case. The State must keep a record with details of the date and place where the remains were found, how they were identified, the possible cause of death, and the location of the subsequent burial. C. Integral measures of guarantees of non-repetition reparation: satisfaction, rehabilitation, and 272. The denial of justice to victims of grave and massive human rights violations, such as those that occurred during the massacres, gives rise to numerous adverse effects not only in the individual sphere of the victims, but also in their collective sphere.347 Thus, it is evident that the victims of prolonged impunity will suffer different effects not only of a pecuniary nature owing to the search for justice, but also other sufferings and harm of a 344 Cf.
