70 of Physical and Moral Integrity of Children, and d) the Special Unit for the Investigation of the Deaths of Children and the Public Human Rights Prosecutors’ Office, as the organization in charge of investigating and punishing the violations of human rights of children and teenagers. 189. This Tribunal observes that the State has specialized organizations to attend to the problems through which this group of the Honduran population is going through. However, as has been stated by the representatives and the Commission, the creation of said institutions has not represented measures that are sufficient or efficient in counteracting the extrajudicial killings of the youngsters in Honduras, or in guaranteeing the rights of children and youngsters. 190. In the opinion of this Court, it is necessary that all institutions created to prevent and sanction the violations of human rights against children and youngsters be fully effective in their performance. The stipulations of the domestic legislation and, in this case, the institutions created to guarantee the human rights of children and youngsters, have to be effective, which means that the State must adopt all the measures necessary so that the stipulations of the Convention are really complied with.111 191. Therefore, the State must provide the institutions with suitable personnel trained for the investigation of extrajudicial killings and of the adequate recourses so they may fully comply with their mandate. For the investigation of extrajudicial killings the international norms on the documentation and interpretation of the forensic elements of evidence must be taken into consideration with regard to the commission of acts of torture, and especially those defined in the Manual of the United Nations on the Prevention and Efficient Investigation of Extralegal, Arbitrary, and Summary Killings.112 a) Obligation to investigate the facts that caused the violations of the present case, and identify, prosecute, and sanction those responsible 192. The Court has defined impunity as an offense within the obligation to investigation, persecute, capture, prosecute, and sentence those responsible for the violations of the rights protected by the American Convention.113 The State is obliged to fight this situation through all means available, since it promotes the chronicle repetition of violations to human rights and the total defenselessness of the victims and their next of kin.114 111 Cfr.
