10 (2) The technical report we are attaching hereto points to the existence of evidence that at least one of the columns which supported the structure of the Pavilion was blasted with dynamite from the outside, causing the final collapse. Our evaluation has revealed, likewise, serious inconsistencies in the official explanation as to the manner in which the inmates, who were allegedly enclosed in tunnels, lost their lives by the collapse of the Pavilion. V 44. During the public hearings held on this case, the Government abstained from presenting evidence and the Commission introduced the witnesses and experts whose statements are summarized below. 45. Witness Sonia Goldenberg stated that, as a journalist, she had interviewed Jesús MejíaHuerta who informed her that after the bombing of the correctional facility some 70 inmates were still inside; that they were summoned in groups and that there were executions; that he had eight or ten bullet wounds and was thrown into a ditch with others who were wounded. Later, the Blue Pavilion was blown with dynamite. She also stated that she interviewed Juan Tulich-Morales who informed her that he knew that the leaders arrested were taken to the naval base of San Lorenzo and were later shot. 46. Witness Pilar Coll stated that, in August 1987, she was in an office authorized by the investigative Commission of Congress to take the testimonies of the relatives of those detained in the correctional facilities and of some of the survivors; that she interviewed Jesús Mejía-Huerta who told her in greater detail what he had already stated to the previous witness. The witness also stated that some relatives of the prisoners knew that some of the survivors had disappeared. 47. Expert Guillermo Tamayo-Pinto Bazurco, a civil engineer, stated that in 1987 the Projects and Construction Center, of which he is Chairman, was contracted by the Congressional Commission that was investigating the events at the correctional institutions; that he visited the Correctional Island of El Frontón; that the Blue Pavilion had been demolished and that the total demolition had been caused by plastic explosives placed at the foot of the columns; that he had seen the traces of the shock wave outside the building; that there were twenty meters of tunnels but that they did not affect the solidity of the structure and that there was no indication that there had been explosions in them. 48. Expert Enrique Bernardo-Cangahuala, a civil engineer, stated that he had been hired some years before by the Senate Commission to make an assessment, from the civil engineering point of view, of the problem at the San Juan Bautista Correctional Facility; that they prepared a report after visiting the site and gathering background information; that the Association of Engineers endorsed the report; that they found tunnels but that those tunnels did not go through to openings on the coastline; that they found evidence of explosives on the Pavilion columns; that with the work of ten workers the debris could have been removed in one month; that, had the purpose of using explosives been to enter the Pavilion, the explosives would have been placed on the walls, thus, the objective was to demolish the building; that there is no evidence that an explosion would have taken place inside the building; that a plastic explosive could not provoke an explosion comparable to that of dynamite; and that it had been possible for the people to take shelter inside the tunnels, but not for them to get out. 49. Witness Ricardo Aurelio Chumbes-Paz stated that he is a lawyer and that at the time of the events he was Instructional Judge of El Callao and is currently a Criminal Judge; that on June 18, 1986, he heard on the radio about certain riots at the El Frontón Correctional Facility; that, at approximately 1:00 pm, the President of the Supreme Court commissioned him to observe the events without decision-making powers in order to report on them later; that the Naval authorities denied him the means to travel to the correctional island; that, at approximately 3:00
