3 Manuel Velasco-Clark, Assistant Gustavo Gallón-Giraldo, Adviser Juan E. Méndez, Adviser José M. Vivanco, Adviser. II 10. According to the petition, Isidro Caballero-Delgado and María del Carmen Santana were detained on February 7, 1989, in the locality known as Guaduas, under the jurisdiction of the Municipality of San Alberto, Department of Cesar, Colombia, by a military patrol composed of units of the Colombian Army stationed at the military base of Líbano (jurisdiction of San Alberto), attached to the Fifth Brigade headquartered in Bucaramanga. 11. According to the petition, the detention took place because of Mr. Isidro Caballero’s active involvement as a leader of the Santander Teachers’ Union for a period of 11 years. Prior to that, and for the same reasons, he had been held in the Model Prison of Bucaramanga, charged with belonging to the Movimiento 19 de Abril, but was released in 1986; since that time, however, he was constantly harassed and threatened. María del Carmen Santana, about whom the Commission had “very little information, was a member of the Movimiento 19 de Abril (M-19)” and worked with Isidro Caballero in enlisting community participation for the “Meeting for Coexistence and Normalization” which was to be held on February 16, 1989, in the Municipality of San Alberto. This activity had been planned by the “Regional Dialogue Committee” and involved “organizing meetings, fora and debates in various regions in an effort to find a political solution to the armed conflict.” 12. The petition states that on February 7, 1989, Elida González, a peasant woman who was passing the spot where the victims were captured, was detained by the same Army patrol and later released. She saw Isidro Caballero, wearing a camouflage military uniform, and a woman who was with them. Javier Páez, a resident of that region who served as their guide, was detained by the Army, tortured and later set free. From the interrogation he was subjected to and the radio communications of the military patrol that detained him, he learned of the detention of Isidro Caballero-Delgado and María del Carmen Santana. After his release, he notified the unions and political organizations to which they belonged. They, in turn, notified the relatives of the detained individuals. 13. The petition reports that Isidro Caballero’s family and various union and human rights organizations began to search for the detainees at the military facilities. They were told that Isidro Caballero and María del Carmen Santana had not been detained. Legal and administrative actions were taken in an attempt to establish the whereabouts of the couple who had disappeared and to punish those directly responsible, all to no avail. No reparations were obtained for the damages caused. 14. Among the judicial actions taken, the petition mentions a writ of habeas corpus filed with the First Superior Court of Bucaramanga, an investigation in the ordinary criminal courts before the Second Criminal Examining Magistrate and a military criminal investigation before Military Criminal Examining Magistrate 26, attached to the Santander Battalion based in Ocaña. The following administrative measures were also taken: action by the Office of the Presidential Adviser for the Defense, Protection and Promotion of Human Rights; action by the Bucaramanga Regional Prosecutor’s Office; proceedings and negotiations by the Second Assistant Prosecutor for the Judicial Human Rights Police and by the Assistant Prosecutor for the Military Forces; and, also
