166 304. Regarding this matter, the Court reiterates its jurisprudence constante293 that no domestic legal provision of law can impede compliance by a State with the obligation to investigate and punish those responsible for human rights violations. Specifically, the following are unacceptable: amnesty provisions, rules regarding extinguishment and establishment of exclusions of liability that seek to impede investigation and punishment of those responsible for grave human rights violations –such as those of the instant case, executions and forced disappearances. The Court reiterates that the State’s obligation to adequately investigate and to punish those responsible, as appropriate, must be carried out diligently to avoid impunity and repetition of this type of acts (supra para. 297). b) Identification of the victims of the Mapiripán Massacre and their next of kin 305. The Court deems it indispensable for the State, for purposes of reparation, to individually identify the victims who were executed and made to disappear, as well as their next of kin. The Court appreciates the actions undertaken by the State to recover the remains of persons executed in Mapiripán who were thrown into the Guaviare River. The State must complete said tasks, as well any others that may be necessary, for which it must resort to all possible technical and scientific means, taking into account pertinent provisions regarding this matter, such as those set forth in the United Nations Manual on the Effective Prevention and Investigation of Extra-Legal, Arbitrary and Summary Executions. This obligation includes the duty to identify the victims listed with their first name, with a name and a nickname, with only a nickname or with a position, that is, a black man called N.N. Nelson (black man), Teresa ‘la Muerte’, ‘la Arepa’ and the ‘President of Asociación Danta”, Agustín N.N., el Pacho N.N., Teresa N.N or Teresa “la muerte”, N.N. “la arepa”, N.N. Morales, a body identified as N.N, an unidentified male, a woman from the corregimiento of Charras and a man from La Cooperativa N.N. (supra para. 96.52), as well as those who are individually identified after notification of the instant Judgment. 306. To make individual identification effective and feasible, the State must publish an announcement by means of a radio broadcaster, a television broadcaster and a newspaper, all of them with national coverage, stating that it is attempting to identify the victims executed or made to disappear during the Mapiripán Massacre, as well as their next of kin, with the aim of recovering the remains of the former and delivering them to the latter together with the pertinent reparations. It must take the appropriate actions to identify the next of kin of Jaime Pinzón, Raúl Morales, Edwin Morales, Manuel Arévalo, Omar Patiño Vaca, Eliécer Martínez Vaca, Uriel Garzón and Ana Beiba Ramírez, to give them the pertinent reparations. In the case of said victims who have been individually identified with their name and surname, as well as those for whom there is only a name, a name and a nickname, or only a 293 See Case of the Moiwana Community, supra note 4, para. 206; Case of the Serrano Cruz Sisters, supra note 11, para. 172; Case of the Gómez Paquiyauri Brothers, supra note 182, para. 175; Case of the 19 Tradesmen, supra note 190, para. 262; Case of Molina Theissen.
