27 Coatepeque, Quetzaltenango; its aim was “to make an end to all the guerrilla forces”. The commander of this task force was Ismael Segura Abularach, and Colonel Julio Roberto Alpírez also took part in it. There he met other guerrilla combatants who had been captured, among them, one known as Bayardo (Otoniel de la Roca Mendoza). On March 12, 1992, the third battalion of Military Zone No. 18 in San Marcos captured Bámaca Velásquez, in Montúfar in the Municipality of Nuevo San Carlos, Retalhuleu. He was able to see him in an office of the detachment in Santa Ana Berlín de Coatepeque, where he was kept tied up. “Captain Laco”, Major Mario Ernesto Sosa Orellana and “Captain Soto” were with him. The latter tried to obtain all possible information about the guerrilla from Bámaca Velásquez. The day following the capture of Bámaca Velásquez, the witness was sent to talk to him to tell him to collaborate, or otherwise he would be tortured. On that occasion, he spoke to Bámaca Velásquez alone, and the latter asked the witness, if he was able to escape, to say that he [Bámaca Velásquez] had been captured alive and was in Santa Ana Berlín. He saw Bámaca Velásquez on many occasions during the approximately one month that his detention in Santa Ana Berlín lasted. In June 1992, he heard Major Mario Sosa Orellana say that “Comandante Everardo had escaped from the capital, but that [...] he had once again been captured and shot because he had tried to escape”. However, in July, he saw Bámaca Velásquez in Military Zone No. 18 once again, together with Colonel Julio Roberto Alpírez and Major Sosa Orellana, who told the other detainees that “they could not communicate with him”. He helped to collect some medical equipment that was for Bámaca Velásquez and kept guard on the room where he was kept. Colonel Alpírez told him off for being in that place. On another occasion, he saw Bámaca Velásquez “lying half-naked on a bed, with his eyes bandaged and an arm and leg bandaged” and with his face swollen. Beside him was what appeared to be an oxygen cylinder. On about July 22, 1992, he saw Bámaca Velásquez for the last time in Military Zone No. 18 in San Marcos. On that occasion, the Army was preparing a military operation in the “El Porvenir” detachment; to this end, they recorded a guerrilla radio communication and sent it to him so that he could give it to Bámaca Velásquez for the latter to disclose what the guerilla were saying in the communication. Later, he heard from Anastasia López Calvo that, during July, Bámaca Velásquez was at the Quetzaltenango military base No. 1715 and that his treatment had been different there, because “they made him do the cleaning where he was and he was not tied up during the day.” After having been detained for one year and ten months, and having obtained the confidence of the members of the armed forces sufficiently, the witness used a license to leave with Simeón Cum Chutá and Martín Pérez Cabrera to spend Christmas with his family, and took advantage of this opportunity to escape. b.
