For this reason and as ordered by this Tribunal since the delivery of the Judgment in the case of Barrios Altos V. Peru, the State can no longer apply amnesty laws, which lack legal effects, present or future (supra para. 163), or rely on concepts such as the statute of limitations on criminal actions, res judicata principle and the double jeopardy safeguard or resort to any other measure designated to eliminate responsibility in order to escape from its duty to investigate and punish the responsible224. 183. Pursuant to the case-law of this Tribunal225, during the investigation and prosecution, the State must ensure full access and procedural capacity of the victim's next-of-kin in all the stages of this investigation, in accordance with the domestic law and the rules of the American Convention.

B.2) Castro Determination of the whereabouts of Kenneth Ney Anzualdo 184. The Inter-American Commission requested the Court to order the State to “avail itself of all means necessary to investigate, identify and disclose the whereabouts of Mr. Kenneth Ney Anzualdo, or “his remains”, in which case the State shall deliver his remains to his next- of- kin and should this not be possible, “provide them with corroborated and convincing information regarding the whereabouts thereof.” The representatives requested that the State complies with the foregoing, bearing in mind certain procedures and technical criteria. The State did not submit specific allegations in this regard. 185. The Tribunal recalls that the whereabouts of Mr. Anzualdo Castro has still not been established; as a consequence, the State must, as a means for redress of the right to truth of the next-of-kin227, immediately proceed to search for and locate him or his mortal remains, by means of a criminal investigation or another effective and appropriate procedure (supra párr. Should the mortal remains be found, they must be delivered to the next-of-kin, prior genetic verification of blood relationship, as soon as possible and at no cost. Also, the State must cover the burial expenses, in common agreement with the next-of-kin. B.3) Criteria to identify the persons that disappeared during the internal conflict 224 Cf.
