Testimony of Luis Alberto Colonel in the Guatemalan Army Gómez Guillermo, Lieutenant He has been an Army officer and formed part of the intelligence unit called G-2. He later stated that he had not worked as an intelligence officer. He did not know that the Army captured or arrested members of the guerrilla, or that there were clandestine detention centers for those who had been captured. When such persons gave themselves up they were not mistreated. The sources of information available to “military intelligence” to find out about guerrilla activities, in the context of the “armed conflict”, were the local population or information provided by guerrillas who had given themselves up voluntarily. The Army did not conduct interrogations, but rather “interviews” of the former guerrillas who gave themselves up voluntarily and claimed amnesty, such as the former guerrillas, de la Roca and Boitsiu. In these circumstances, the procedure followed was to immediately inform the superior officers and “then, bring the press so that, both their families and the rebels would know [...] that this man was now 'adaptado a la vida política' (re-adapted to society)”. The “interview” was carried out by the competent judge, in the presence of representatives of the Public Ministry and lawyers, so that it could then be “used for or against in a formal proceeding.” He was acquainted with Otoniel de la Roca, and knew that he was a former member of the guerrilla, and did not work in the Army. He had spoken to him and to Luis Boitsiu, in 1991, regarding the existence of “schisms” in the guerrilla. He did not know that Otoniel de la Roca had been captured by the Army, tortured and used to “obtain intelligence” about the guerrilla. Later he heard that Otoniel de la Roca Mendoza had been detained by the National Police Force because he was carrying a gun and uttering threats. He heard that de la Roca had made declarations to the press, but not that he had said that “something would happen to him or his family” if he did not make such declarations. He was not acquainted with either Santiago Cabrera López or Anastasia López Calvo, or a member of the armed forces named José Víctor Cordero Cardona.
