The victim was made to listen to his sister’s screams: the kidnappings with torture of five people evidenced by the prosecution of 12 former officials

Visiting Judge Jaime Arancibia indicted them for the crime of kidnapping with serious injury. They must remain under house arrest while their release is decided by the Court of Valparaíso. The application of electricity, humiliation, beatings, and threats are some of the duress suffered by five victims of kidnapping by State agents, which occurred starting in March 1974 in Valparaíso.

The visiting judge for human rights violation cases of the Court of Appeals of that region, Jaime Arancibia Pinto, indicted 12 former Navy officials for their responsibility in the crime of kidnapping with serious injury.

In the resolution (case file 47-2016), Judge Arancibia indicted Ricardo Alejandro Riesco Cornejo, Juan de Dios Reyes Basaur, Valentín Evaristo Riquelme Villalobos, Bertalino Segundo Castillo Soto, Jaime Segundo Lazo Pérez, Alejo Esparza Martínez, Héctor Vicente Santibáñez Obreque, Eduardo Mauricio Núñez Contreras, Sergio Hevia Febres, Gilda Mercedes Ulloa Valle, Guillermo Tomás Morera Hierro, and Reginaldo Rebolledo López as authors of the crimes.

However, all will remain under house arrest due to their advanced age and the Covid-19 pandemic, while the appellate court determines whether to grant them provisional release.

They asked him about the MIR

“C. was detained around noon on April 16, 1974, at his home in the city of Valparaíso, by 4 Chilean Navy officials dressed in civilian clothes, who, without a written order, without stating a cause, and with great violence, took him out of the property and put him into a car, being transported to the Cuartel Silva Palma.

In said place, he was subjected to two long interrogations, in which he was asked about the MIR organization and was confronted with other detainees, such as Silvio Pardo Rojas, currently forcibly disappeared.

In these interrogations, he received physical and psychological mistreatment, such as kicks and punches, the application of electric current, and the drowning tactic known as ‘dry submarine.’ He remained detained at the Cuartel Silva Palma for about 15 days, being transferred on May 1, 1974, to the Puchuncaví prisoner camp, a place where he was subjected to forced labor.

After a month, he was transferred to the Valparaíso Public Jail, entering as a defendant in ‘libre plática’ (open communication status), remaining in that situation until May 1975, the date on which he was sentenced by a War Council as the author of the crimes of infringement of the State Internal Security Law and illicit association, to the penalty of banishment, with his expulsion from the country being decreed, living in England until the year 2000.”

They made him listen to his sister while they tortured her

“R. was detained in March 1974 at the home that his sister, A., and his then-brother-in-law, A., had in the downtown area of the city of Valparaíso, since upon arriving and entering it with the key he possessed, he realized that the house had been raided, finding other people inside, who took him prisoner and took him along with his brother-in-law to the Cuartel Silva Palma, in the same city.

He was put into the back of a pickup truck, which was carrying Carabineros plus a Lieutenant. In said place, he was subjected to interrogations, in which he was asked about weapons and about people from the MIR.

In these interrogations, he received physical mistreatment, such as the application of electric current, and psychological mistreatment, such as threats and being made to listen to how his sister was also being subjected to torture.

He recognizes in this facility the former Chilean Navy official Ricardo Riesco Cornejo, who at that time held the rank of Lieutenant, and was in charge of raiding his parents’ home in search of documents kept on microfilm, based on information obtained from his sister while under torture and information obtained from himself, an agent nicknamed ‘Telémaco,’ who would correspond to the former Chilean Navy official Juan Reyes Basaur, another agent nicknamed ‘Profesor,’ who would correspond to the former Chilean Navy official Manuel Leiva Valdivieso (currently deceased), and the former Chilean Navy official Guillermo Morera Hierro, who was in charge of the custody of the detainees. It was Morera Hierro who transferred him along with other companions to the Puchuncaví prisoner camp in the last days of April 1974, a place where he was subjected to forced labor. At the end of May 1974, he was transferred to the Valparaíso Public Jail, entering as a defendant in ‘libre plática,’ remaining in that situation until May 1975, the date on which he was sentenced by a War Council as the author of the crimes of infringement of the State Internal Security Law and illicit association, to the penalty of banishment, which was later commuted to one of internal exile, which he served in the city of Arica.”

They gave her injections

“A. was detained in March 1974 at her home located in the downtown area of the city of Valparaíso. She was transferred to the Cuartel Silva Palma, remaining in said facility until mid-April 1974, being subjected to interrogations and physical and psychological mistreatment by her interrogators, mostly men, with a woman also being among them who also interrogated, who would correspond to the former Chilean Navy official Gilda Ulloa Valle.

Those mistreatments consisted of beatings, application of electricity, forced body posture, application of injections, and isolation in a punishment cell, among others. She also recognizes the former Chilean Navy official Guillermo Morera Hierro, an officer who was in charge of the detainees at the Cuartel Silva Palma, who allegedly took her out on two occasions to the facility’s bathrooms, forcing her to undress and shower in front of him, and even ordering another lower-ranking official to touch her without her consent.

She also recognizes an agent nicknamed ‘Telémaco,’ who would correspond to the former Chilean Navy official Juan Reyes Basaur. After remaining for nearly a month detained at the Cuartel Silva Palma, she was transferred as a prisoner to the Buen Pastor women’s jail in the city of Valparaíso.

In May 1975, she was sentenced by a war council held in case file Rol A-344 of the Naval Court of Valparaíso as the author of the crime of infringement of the State Internal Security Law and illicit association to the penalty of banishment, which was later commuted to one of internal exile, which she served in the city of Antofagasta, until 1978, when the Amnesty Decree Law was applied to her.”

Electric current

“A. was taken prisoner on March 27, 1974, at his home in the downtown area of the city of Valparaíso. The detention and raid were carried out by civilian personnel of the Chilean Navy, belonging to the Intelligence Service; he was beaten at the scene and threatened with firearms, to then be transferred to the Cuartel Silva Palma, in the same city.

In the aforementioned barracks, he was subjected to interrogations and severe torture that included the application of electric current, bodily beatings, and threats, which allegedly left him in poor physical condition, having to be transferred to the Naval Hospital on one occasion.

In said interrogations, he was asked about people and the location of weapons. He was also subjected to a confrontation with A., who at that time was his wife and was also detained. At the end of April 1974, Saieg was transferred along with other detainees to the Puchuncaví prisoner camp, where he remained for about a month, to then be transferred to the Valparaíso Public Jail.

In May 1975, he was sentenced by a war council held in case file Rol A-344 of the Naval Court of Valparaíso as the author of the crime of infringement of the State Internal Security Law and illicit association, to the penalty of banishment, which was later commuted to one of internal exile, which he served in the city of Antofagasta, until 1978, when the Amnesty Decree Law was applied to him.”

50 days of interrogations “E. was detained at the end of March 1974 at the home of A. and A., in the downtown area of Valparaíso. Inside the property were 4 or 5 armed subjects, who without identifying themselves took him prisoner, and proceeded to interrogate him immediately, subjecting him to torture.

Then he was taken out of that place and transferred to the Cuartel Silva Palma, a place where he remained for about 50 days and was subjected to constant interrogations that were accompanied by kicks and punches, and the application of electric current.

He was transferred to the Puchuncaví Prisoner Camp, a place where he was for about three weeks to then be passed to the Valparaíso Public Jail as a prisoner, until May 1975, when he was sentenced by a war council held in case file Rol A-344 of the Naval Court of Valparaíso as the author of the crime of infringement of the State Internal Security Law and illicit association, to the penalty of 5 years and 1 day of imprisonment and 15 years of banishment.

Before being sentenced, he was again taken to the Cuartel Silva Palma, remaining for about 5 days, being again interrogated and heavily tortured. Of the 5 years and 1 day of imprisonment, he only managed to serve a year and a half since Norway granted him asylum, leaving the country in November 1976.” by Andrés López Vergara

Case File No. 144.133-2013: kidnapping and torture case of Morelia del Rosario Fernández Montenegro

29.- Extrajudicial statements that Juan Humberto Campos Cifuentes provided before the PDI’s Human Rights Crimes Investigation Brigade, on pages 356 and 486, who points out that by September 11, 1973, by orders of Rodolfo Stange Oelckers, third in command of the Valparaíso Prefecture, he had to go with a group of Carabineros to take control of the Valparaíso Jail.

In the month of October of that year, they sent him to the anti-subversion and urban guerrilla course at the “Miller” Marine Infantry detachment, which lasted about 3 months. In December 1973, he was transferred to the 10th Special Forces Precinct, whose chief was Major Raúl Arellano Castillo.

He worked there until the summer of 1974, when he was assigned as a liaison to the Naval War Academy, a unit where combined institutions of the different Armed Forces and order forces worked; he worked in the Analysis Department under the orders of Corvette Captains Rigoberto Cruz Johnson and Erwin Conn Tesche; in that place, his function was to classify by alphabetical order the background sheets of the detainees and of people to be detained, a task that had also been started by Carabineros Lieutenant Manuel Díaz Vieira, already detained.

The functioning of said unit was compartmentalized, but he knew that many naval officials as well as those from other institutions had been working there since the first days of the establishment of the Military Dictatorship, among whom he includes the aforementioned Cruz and Conn.

He also remembers, in this same capacity, a naval officer with the surname Fernández, the Marine Infantryman Ricardo Riesco, whom on one occasion upon entering a small room at the Cuartel Silva Palma suddenly, I caught torturing a person on a strap bed, known as a “grill,” on which electricity was applied; Sergeant Hevia, who on some occasions accompanied him as a driver to carry out certain duties in the city, among which he remembers having gone to the Federico Santa María Technical University with the mission of contacting the Rector, who gave them lists of people with political affiliations to be expelled from said educational institution.
