6 justice, as well as the former and current inhabitants of Ituango7. Moreover, when necessary, it is important to expose the existence of complex criminal structures and their connections which made the violations possible8. 15. That the Court also determined that the State did not guarantee prompt justice to the victims, inasmuch as most of the responsible have not been included in the investigations or have not been identified or accused despite the fact that the incidents of this case were committed by a group of approximately 30 armed men with the knowledge, tolerance and consent of the Colombian Army. Even, most of the people who have been sentenced to serve a prison term have not been detained.9 16. That the information forwarded to the Tribunal does not allow verifying the existence of a significant progress as to the compliance with this measure of reparation. Of the eight people on whom the State has provided information during the procedure to monitoring compliance with the Judgment, six were already joined to the proceedings of this case on the date this Order is issued by the Tribunal.10 Furthermore, the information forwarded by the State regarding this measure of compliance refers to the proceedings conducted between the year 2006 and February 2008. Therefore, the Tribunal has no information on the records of pleadings of the last 15 months within the proceedings conducted or the measures adopted to speed up the investigation and the judicial process and remove all obstacles, de facto and de jure, that maintain impunity. The foregoing means that after 11 and 12 years of the massacres of La Granja and El Aro, respectively, the violations so declared in the case at hand are still in the same condition of impunity that they were at the moment of the delivery of the Judgment, almost three years ago.11 17. That the murder of Mr. Francisco Enrique Villalba Hernández, a paramilitary officer who had acknowledged his participation in the case and was under home detention in the custody of the State, excluded the possibility that Mr. Villalba provide further information on other perpetrators who participated in the massacres of Ituango, eliminating in this way a possible source of evidence for pending criminal proceedings. In this connection, the Tribunal pointed out (supra Considering clause 14) that the State must offer protection to witnesses in cases of serious human rights violations. Mr. Villalba, due to his participation in the facts, was a witness to the case and was under home detention on the date of his murder, that is to say, under the protection of the State. In this sense, the Tribunal recalls that the State must adopt the measures necessary to protect other witnesses, justice administrators, victims and their next-of-kin that so require to guarantee that the investigations in the instant case are not being obstructed. 7 Cf.
