19 that they would fit in some holes that Einer had dug, and later they informed Captain Forero-Quintero that they had buried them; that the capture of Caballero-Delgado and María del Carmen Santana was not at the house of a peasant woman but rather in a bus, after Sergeant Vanegas informed them that he had talked with him; that the reason that the peasants say that they captured him there may have been because Vanegas accompanied Caballero-Delgado almost to the highway; that the capture in the bus took place between 6:30 and 7:00 pm; that he asked Segundo about the instructions that Captain Forero had given him, and he answered that they were to kill and disappear the detainees; that he does not know who the third detainee was, but that he is buried with Caballero-Delgado and María del Carmen Santana; that he did not witness the death of the detainees because he was on guard about thirty meters away and only heard the shots, and that the third detainee was killed with a knife; that he can make a sketch of the place of the burial, but that Einer Pinzón is the one who knows the exact place; that the valuables and papers of the detained were given to Captain García-García; that this is the first time that he has testified in a complete form; and that he wants to be given a fair hearing and security for his life and his family.

That the Municipality of San Alberto (El Cesar), the place where the events under consideration occurred, was at that time a zone of intense army, paramilitary and guerrilla activity (specifically the testimony of Gonzalo Arias-Alturo, Carlos Julio Parra-Ramírez, Elizabeth Monsalve-Camacho, Armando Sarmiento-Mantilla, and Juan Salcedo-Lora). b. Notwithstanding the fact that much of the testimony rendered before this Tribunal, both at the public hearing and in Colombia, and in the domestic proceedings conducted in that country differs as to details about the place and the hour of detention, there exists sufficient evidence to infer the reasonable conclusion that the detention and the disappearance of Isidro Caballero-Delgado and María del Carmen Santana were carried out by persons who belonged to the Colombian Army and by several civilians who collaborated with them (testimony of Rosa Delia Valderrama, the minor Sobeida Quintero, Elida González-Vergel, Javier Páez, and the declarations of
