been interrupted.636 Following this, the case file contains numerous statements made by paramilitaries implicated in the case that endorse the line of investigation followed concerning the connection between General del Río and members of paramilitary groups, as those responsible for the events investigated.637 In most cases, the statements consist in voluntary confessions that were transferred from the Justice and Peace procedure as evidence.638 385. Based on the foregoing, the Court finds that no evidence or arguments have been provided that allow it to determine that the State has violated the obligation to investigate with due diligence and to prosecute and punish, as appropriate, in the proceedings relating to Rito Alejo del Río Rojas. b) Investigations undertaken against other members of the Armed Forces 386.

In this regard, it should be repeated that, in this case, the Court has considered it proved that collaboration existed between paramilitary units and members of the Armed Forces in the execution of the Operations Cacarica and Genesis, so that it is surprising that no other member of either of these groups has been accused in the two proceedings. 387. Consequently, the Court finds that the State has not complied with its obligation to investigate with due diligence the other members of the Armed Forces who could have participated in and be held responsible for the events. c) Investigations of members of paramilitary groups 388.
