Juan and Miguel Cardona Quintero 220. On the basis of proven facts, the Cardona Quintero brothers were taken into custody on June 22, 1996 and to date their whereabouts are unknown. According to the statements given by witnesses and Ramón Isaza himself, the IACHR observes that members of the National Army would have been in the group of persons who participated in arresting them. 221. On the basis of a joint review of these elements, as well as the context in which the incidents occurred in Vereda La Esperanza, the Commission deems that military personnel collaborated with the Self-Defense Forces of Magdalena Medio to execute the forced disappearance of the Cardona Quintero brothers. In this regard, the Commission concludes that the State violated the rights to personal liberty, personal integrity, life and recognition as persons before the law, as enshrined in Articles 3, 4, 5 and 7 of the American Convention in connection with the obligations enshrined in Article 1.1 of the same instrument; as well as article I.a) of the Inter-American Convention on The Forced Disappearance of Persons, to the detriment of the Cardona Quintero brothers. 222.

Thus, the Commission deems that, in the present case, the State of Colombia disregarded its obligation to provide special protection to children, especially in a context of armed conflict. Because of this, the State violated Article 19 of the American Convention in connection with its obligations as enshrined in Article 1.1 of the same instrument to the detriment of the Cardona Quintero brothers. 6.3.
