Cuartel Simón Bolívar

Cuartel Simón Bolívar (Spanish for "Simón Bolívar Barracks"), also called Cuartel Lautaro, was a clandestine detention, torture, and killing site in the La Reina commune of Santiago, Chile. It was operated by the National Intelligence Directorate (DINA), the secret police of Augusto Pinochet's military dictatorship. The compound was run by the DINA's Lautaro Brigade, which began as a security detail for the agency's director, Manuel Contreras. In mid-1976 it became a center for interrogating and killing members of the Communist Party of Chile, including much of the party's clandestine leadership. Chilean courts and journalists have described it as an extermination center (centro de exterminio) because prisoners were generally killed after interrogation. Few, if any, are known to have left alive. Bodies were dropped into the sea from military helicopters or thrown into mine shafts and ravines.

The compound's existence became public only in 2007. That year, Court of Appeals justice Víctor Montiglio, investigating the Calle Conferencia Case, obtained the testimony of Jorgelino Vergara, a former teenage servant of Contreras who had worked at the site. Dozens of former agents were charged, and Chile's Supreme Court has since upheld convictions in several cases tied to the compound. Its former commander, Juan Morales Salgado, was among those convicted. The property was later redeveloped as a residential condominium. A memorial was inaugurated nearby in 2016.

Background

The Lautaro Brigade was created in April 1974 to carry out "intelligence" and security work for the DINA's director. According to a court account, it was staffed with personnel from several branches of the armed forces. It first operated from an apartment tower in Santiago's San Borja housing complex, and its early duties included protecting Contreras and his family and investigating complaints. Army captain (later major) Juan Morales Salgado commanded it, assisted by Lieutenant Armando Fernández Larios. Morales answered directly to Contreras.

Sources differ on when the brigade moved to the La Reina property. Journalist Rodrigo Alvarado, summarizing Javier Rebolledo's research, dates the move to early 1975, when the unit had about twenty agents. He says it later grew to about thirty. A court ruling places the move in mid-1975, after Contreras moved his family residence to La Reina. A Supreme Court ruling states that the DINA maintained the compound from late 1975 through at least 1977.

The compound

Sources give the address on Simón Bolívar Street as either 8630 or 8800. Rebolledo has reported that 8630 is now the rear gate of a high school, and that a neighbor told him the compound had actually stood at 8800, where a condominium now stands. Court findings describe the site as a casa quinta (a country-style house on a large lot) adapted for confinement. It had a single entrance gate, a guard booth, a house at the back, a small soccer field, and parking. A building on one side held a dining hall, a kitchen, and locker rooms and bathrooms that were converted into cells. Prisoners typically arrived blindfolded in Chevrolet C-10 pickup trucks.

Operations

From security detail to killing site

In mid-1976 a group led by Army captain Germán Barriga and Carabineros lieutenant Ricardo Lawrence moved into the compound from Villa Grimaldi. It was known as the Delfín group and had about twenty agents experienced in detention and torture. Judicial findings state that their arrival turned the compound from a security brigade into an extermination center. Their main mission was eliminating the Communist Party's leadership and militants. Barriga and Lawrence enjoyed some autonomy, but most agents told investigators that both took orders from Morales, who also kept a trusted group of Navy marines. Orders to kill reportedly came from Contreras and were relayed through Morales. Barriga died by suicide in January 2005, before the compound became public.

Personnel came from the Army, Navy (including marines), Air Force, and Carabineros, along with civilians attached to the services. Many were noncommissioned officers, and several were women. The Navy had maintained that it withdrew all its personnel from the DINA in 1975. La Nación reported that the investigation showed Navy agents continuing to serve in the Lautaro Brigade afterward.

Detention, torture, and killing

Prisoners were held in the converted locker rooms and questioned by Morales, Barriga, and Lawrence. Torture included electric shocks on a metal frame known as la parrilla ("the grill"), the "dry submarine," and beatings. Interrogators sought information on the Communist Party's operations, resources, members, and organization. Rebolledo reports that few prisoners survived more than a week or two. Detainees were killed by beating, by suffocation with plastic bags, or by injection. A court account describes the injected substance as apparently Pentothal, while press reports say cyanide. Army nurse-lieutenant Gladys Calderón was named as administering injections.

Disposal of bodies

The bodies were wrapped in polyethylene and burlap sacks and tied with wire to lengths of railroad rail. At night they were taken to an Army training ground at Peldehue, north of Santiago, and loaded onto Army Aviation Command Puma helicopters, which dropped them into the sea off the coast of the Valparaíso region. Other bodies were thrown into shafts at an abandoned mine at Cuesta Barriga or into ravines in the Cajón del Maipo. Parts of the remains of at least two victims were later found at Cuesta Barriga. The body of Communist Party leader Marta Ugarte washed ashore on September 12, 1976, after the rail came loose. La Nación reported that investigators linked her to the compound.

Alleged weapons testing

Former agents told Judge Montiglio that Michael Townley, who ran a DINA chemical laboratory, visited the compound to test sarin made by the chemist Eugenio Berríos on prisoners. Vergara, as recounted by Rebolledo, described two foreign detainees, Peruvian or Bolivian, who were used to test an electric-dart weapon and then killed with sarin. In 2015 a judge ruled on the death of Army corporal Manuel Leyton Robles, a DINA member. Leyton had been taken to the compound in March 1977 after telling Carabineros about the DINA team's operations, and he died on March 29 at a clinic. The judge concluded that he had been killed by a toxic substance, and that the evidence supported the use of sarin, although the autopsy could not confirm it.

Victims

Rebolledo estimates that about 80 Communist Party members passed through the compound, including the complete membership of several clandestine party leaderships. He suspects another 100 to 150 unidentified people were also held there. Accounts vary on whether the party lost two or three clandestine leaderships there in 1976. Rutas de la Memoria, a program of Chile's Ministry of National Assets, states that no one left alive, based on judicial testimony. Vergara recalled one young man who was beaten, forced to drink alcohol, and dumped by a roadside alive.

Víctor Díaz López, the party's acting general secretary in hiding, was arrested at his home in Las Condes around 1 a.m. on May 12, 1976. He was held at Villa Grimaldi and elsewhere, then at Simón Bolívar for more than eight months. Lawrence later testified that Pinochet visited Díaz at a DINA safe house in the Cajón del Maipo. In early January 1977, Contreras reportedly ordered Morales to kill him. According to the judicial reconstruction, an attempted injection failed to kill him, and two agents then suffocated him with a plastic bag. His body was dropped into the sea and never recovered. Investigators first attributed the killing to two Navy marines. Army corporal Juvenal Piña later confessed to it.

A second wave of arrests in December 1976 brought in Fernando Navarro, Lincoyán Berríos, Horacio Cepeda, Juan Fernando Ortiz, Héctor Véliz, and Reinalda Pereira, a medical technologist who was pregnant. Courts found that all were taken to the compound, tortured, and made to disappear. Pereira was seized on December 15, 1976, while waiting for a bus in Ñuñoa. The government later claimed that she had crossed into Argentina on foot. A court found the supporting travel record to be forged. La Nación reported in 2007 that investigators believed Gladys Marín's husband Jorge Muñoz and Communist leaders Fernando Ortiz and Waldo Pizarro were also killed there.

Discovery and investigation

The case that exposed the compound began on January 12, 1998, when Gladys Marín filed the first complaint in Chilean courts against Pinochet. It concerned the disappearance of Communist Party leaders arrested in 1976. Known as the Calle Conferencia Case after a house on Conferencia Street where agents set a trap, it covered a DINA plan to detain, torture, and disappear the party's clandestine leadership. The Rettig Report had noted that from 1975 to 1976 the DINA pursued Communist Party members who had gone into hiding after the crackdown on the Revolutionary Left Movement (MIR).

The breakthrough came in late 2006, when a former agent told investigators that a man named "Jorge Vergara" had killed Díaz. Police from the Investigations Police's Special Affairs and Human Rights Brigade traced him. On January 19, 2007, they found Jorgelino Vergara in the Maule Region. Vergara had come from a poor rural family. As a teenager he worked in Contreras's household, and in 1976 the DINA hired him under an alias. At the compound he served coffee, stood guard, and cleaned up after torture sessions. His testimony to Montiglio named many agents and described the compound's operations. Morales and another agent, Jorge Pichunmán, acknowledged knowing him. Morales admitted that Contreras had ordered Díaz's killing.

Charges spread quickly. By March 2007 the Calle Conferencia case had more than 40 defendants, the most of any human rights case in Chile up to that point. Vergara was briefly detained but was released, since he had been a minor at the time of the events. Because the case file was under seal, the details of his account emerged only later. Journalist Javier Rebolledo published them in his 2012 book La danza de los cuervos.

Prosecutions

Several judgments have addressed crimes at the compound:

• In June 2021, the Supreme Court upheld 20-year sentences for Morales, Pedro Espinoza, Rolf Wenderoth, and Lawrence for eight kidnappings of people who passed through Villa Grimaldi and Simón Bolívar.
• In June 2023, in the second Calle Conferencia case, the Supreme Court convicted 37 former agents in the December 1976 kidnappings and killings. Morales and Espinoza received 20-year sentences for three homicides.
• In November 2023, a judge sentenced Espinoza, Morales, and Piña to ten years each for the kidnapping of salesman Rodolfo Núñez Benavides, who was last seen at the compound in 1976. An appeals court confirmed the sentences in December 2024.
• In October 2024, the case of Reinalda Pereira ended with 36 convictions.
• In February 2025, the Supreme Court upheld convictions of 46 former agents in the first Calle Conferencia case. Espinoza and Miguel Krassnoff received 20 years, and Morales eight.

Some defendants died before verdicts. Bernardo Daza, one of the marines named early in the Díaz investigation, died in 2016, and Morales died in custody on October 8, 2025.

Adriana Rivas, Contreras's secretary, was charged in 2007 with the kidnapping of Díaz and, two years later, with six additional kidnappings in the second Calle Conferencia case. She fled to Australia in 2011 and was later arrested there in February 2019. Prosecutors and the victims' families say she was an operative agent at the compound, and Vergara testified that she took part in torture. She denies all of it, and no Chilean court has convicted her. On April 7, 2026, an Australian Federal Court judge rejected her final challenge to extradition. As of September 2026, an appeal was set to be heard by the Full Federal Court on November 19.

Memorialization

After the revelations, neighbors and human rights groups installed a commemorative plaque at the site in 2007. The property was later redeveloped as a residential condominium. On April 4, 2016, a memorial by architect Nicolás San Martín, chosen through a design competition, was inaugurated in a small plaza a short distance from the former compound, with President Michelle Bachelet present. Local activists said the project grew out of long-running neighborhood and human rights organizing and criticized the municipality for claiming credit. Rebolledo has urged that the site's memory be preserved and that a replica of the compound be built. The Ministry of National Assets lists the site among its Rutas de la Memoria (Routes of Memory).

In media

The documentary El Mocito ("The Young Butler"), directed by Marcela Said and Jean de Certeau, portrays Vergara and his time at the compound. It was selected for the 61st Berlin International Film Festival in 2011. Rebolledo, who worked on the film as a researcher and assistant director, later included Vergara's account in La danza de los cuervos (Ceibo Ediciones, 2012). The documentary El pacto de Adriana, directed by Rivas's niece Lissette Orozco, deals with Rivas's DINA past.
