Commission also advised the complainants to register as third-party plaintiffs with the Public Prosecution Service in order to determine reparations for the damages caused.13 40. The State says that in order to identify viable alternatives for resolving the matter and to create the conditions necessary for it to redress the harm inflicted, an agreement was signed on September 17, 2002, by the victim’s father, José Tomás Trueba, and the authorities.14 In that agreement the Secretariat of National Defense states that Mirey Trueba Arciniega’s death was probably caused by a soldier belonging to that same Secretariat and, consequently, it compensated the family for the moral and material damages inflicted in the amount of 117,822.00 Mexican pesos, and it further states that José Tomás Trueba Loera accepted and received that amount as redress for the moral and material damages.15 The agreement also stipulates that José Tomás Trueba shall not pursue any present or future civil or administrative action. Thus, the State claims that it thereby reached a settlement with the victim’s next-of-kin and asks that the IACHR ratify the agreement since, in this case, it has been shown that the incident was investigated and the perpetrator was tried and punished.16 41. The State claims it has met the obligation of ensuring the free and full exercise of the rights enshrined the American Convention, per Article 1(1) thereof, in that it has complied with its duty of prevention by enacting legal, political, administrative, and cultural provisions that promote respect of the right to life.17 IV.
