12 that Pinzón-Fontecha had died; that he located Arias-Alturo who told him, after the questioner had promised not to make a recording or take written notes, that he and Pinzón-Fontecha had been in the Army and, although they later retired, they continued collaborating and sporadically went on patrol with groups from the Army; that they were patrolling with three members of the Army in the zone of Guaduas when another patrol brought two detained teachers; that they killed them by shooting them with a pistol, buried them in a common grave, had to cut up the bodies, and that a lieutenant, a sergeant, a corporal, and two civilians participated. The witness continued, saying that he had more than three interviews with AriasAlturo to convince him that he was not going to compromise him, and he made two reports to Doctor Navarro; that from his experience as a professional investigator he did not doubt what Arias-Alturo told him; that Doctor Navarro told him to offer a sum of money to Arias-Alturo in return for a formal statement, but that Arias-Alturo refused and was reticent and did not want to be interviewed by him anymore; that last year the declarant was summoned to the National Office of the Attorney General, and that there he said what he was now saying; that in the interview with Rosa Delia Valderrama she told him that the Army patrol had captured a teacher and his companion, and he found her to be believable; that they took a written affidavit from Mrs. Valderrama, but that he does not remember if they also took one from Javier Páez; that due to his experience in dealing with informers, he believed AriasAlturo, because his version of the events coincided with that of Javier Páez, he gave an exact description of the site, and he made his statement without pressure and in a spontaneous manner; that one of the reasons for offering money to Arias-Alturo was to find the bodies, but Arias-Alturo refused to accompany them, and in that type of area it is difficult to make a search; that he transmitted the information that he received to his superior and he does not know if it was sent to the judicial authorities; and that from the house of Mrs. Valderrama it is some two thousand five hundred or three thousand meters to the site where the informer said the bodies were buried. 38.
