Case 2759





1.          On December 5, 1977, the Commission received the following denunciation:


“Edwin Antonio Guachalla Viaña, a 24 year old student is a prisoner in the Department of Political Order in La Paz. In the early morning of April 2, 1976, the apartment belonging to Carlos Arispe Terrazas, located on Sucre St. in La Paz, was broken into. In addition to the owner, Edwin Guachalla and Miguel Mendoza were also in the apartment. Agents of the DOP (Department of Political Order) rushed in, firing guns, in order to physically eliminate the occupants of the house. As a result of this occurrence, Edwin Guachalla received 4 gun shot wounds: 1 in his head (slight), 2 in his abdomen (serious), and 1 on his leg (serious). Carlos Arispe died as a result of the incident.


Edwin was transferred in serious condition to the DOP detention center to be subjected to torture and interrogation, without regard for his condition. Subsequently, he fell into a coma and had to be transferred to the Police clinic, where he underwent surgery. While he was in the clinic, agents of the Banzer government tortured him with blows from boles (a lariat with balls) on his wounded leg.


On May 1, he was taken out of the clinic to an unknown destination. According to the nurses, Edwin was still very weak, but he walked out. Ten days later, his mother was given authorization to see him from the door of the cell of the DOP in La Paz, where he was stretched out on a makeshift bed, unable to stand up. This is proof of the fact that during the ten days during which his family was unaware of his whereabouts, he was subjected to torture which left him totally prostrated.


For the following six months, he was kept incommunicado and in handcuffs. For sixty days, he was shackled to the wall with his arms above his head. At the same time, he was subject to constant interrogation under psychological and physical torture. Later, they took off the handcuffs, which left scars on his writs.


He is still in detention sharing a cell with four other people, in a very precarious state of health, due particularly to the fact that the bullet was never taken out of his leg; as a result he limps, and suffers intense pain, but does not receive proper medical attention. Furthermore, he is still not allowed to communicate with members of his family, and the interrogations and the torture continue.”


2.          In a note of April 5, 1978, the Commission transmitted the pertinent parts of the denunciation to the Government of Bolivia, asking it to provide the appropriate information.


3.          In a communication of June 5, 1978, the Government of Bolivia, without referring to torture, replied to the Commission’s request in the following terms:


“On April 2, 1976, during an operation carried out by Security Forces on a safe-house of extremists in Sucre Street in the city of La Paz, where he was hiding along with the ‘Dardo’ group of the PRT-B, Edwin Guachalla was wounded after shooting down Mario Rosales Márquez, a detective. He fled, but was subsequently captured in the Villa San Antonio area of La Paz . The guerrilla, Carlos Arispe Terrazas, was also killed in the skirmish. Before he was detained, he was responsible for distributing subversive propaganda for the PRT-B, particularly in factories, and he was Rubén Sánchez’s contact in the city of Cochabamba. He received military training, ran checks on import houses, and carried out kidnappings of top industry, business and government figures.


“In December 1977, he was brought before the Court to be tried for crimes against the security of the State, in a criminal prosecution for the death of detective Mario Rosales Márquez. He has now been released, under the amnesty decreed by the Supreme Government.


4.          The pertinent parts of the Government’s reply were transmitted to the complainant in a letter of June 28, 1978, and he was invited to make observations on the reply. To date, the complainant has made no observations on the Government’s reply.
