On September 17, 1973, Guillermo Ernesto PETERS CASAS, 19 years old, a driver for a Communist deputy and a militant of the same party, was detained by a patrol of carabineros from the Rahue Police Station.

On the indicated day, at 3:00 p.m., the police group arrived at the victim's home, where a relative informed them that he was at his sister's house in Chahuilco, at the El Cobre estate. He was detained there by the same patrol and taken in a pickup truck belonging to the Agriculture and Livestock Service (SAG) to the Rahue Police Station.

Following them was the victim's own Citroneta, driven by a carabinero; the vehicle was found a few days later, abandoned on the road to Murrinumo, near a bridge. Nothing has been known about the victim's whereabouts or fate since that date, and his presence was denied at the various detention centers in the region.

The Commission formed the conviction that the disappearance of Guillermo Peters occurred after he had been detained by State agents, such an act constituting a violation of human rights. This conviction is based on:

– The fact that the victim's detention is sufficiently substantiated;

– The fact that, following said detention, the arrestee disappeared without his final whereabouts or fate being known;

– The circumstance that his vehicle, in which he had traveled to the place where he was apprehended, appeared abandoned days later and was seen being driven by a police officer;

– The fact that repeated requests for information regarding these events directed to the police authority received no response.

Relatos de los Hechos

Guillermo Peters Casas, 19 years old at the time of the events, a mechanic and militant of the Communist Party, was detained on September 19, 1973, in the town of Chahuilco at the Fundo El Cobre, located in the vicinity of Osorno, while he was visiting his sister, Berta.

His captors were Carabineros Captain Adrián Fernández Hernández and Carabinero Juan Moreira, who were traveling in a green pickup truck belonging to the Agriculture and Livestock Service (SAG). Both uniformed officers, who belonged to the 3rd Carabineros Precinct of Rahue, of which the officer was the Chief, appeared at the victim's home hours before his detention.

On that occasion, they asked his mother, Mrs. María Casas, about his whereabouts, and she informed them that he was at the aforementioned Fundo.

The police then appeared at the home of the Kunst family, located on the same Fundo, as the victim had gone there with his sister. The uniformed officers asked for Guillermo Peters and, upon his identification, informed him that he was under arrest, then placed him into the aforementioned pickup truck.

Before the victim boarded the vehicle, the Carabineros took his documents. One of the uniformed officers got into the Citroneta that the victim had been driving and followed the van that was taking him into custody, which departed in an unknown direction.

The Citroneta would be found days later on the road to Murrinumo. The SAG pickup truck, a FORD F-100, used by the victim's captors, was also found abandoned.

Until the military coup, Guillermo Peters had worked as a driver for the former Communist Party Deputy Rubén Zapata, the owner of the vehicle the victim had at the time of his detention.

The victim's mother, María Casas, made numerous inquiries at the Carabineros, the morgue, the regiment, and other locations in Osorno without being able to learn her son's status. She even went to the 3rd Carabineros Precinct of Rahue, where she was repeatedly denied the presence of Captain Adrián Fernández at the facility. The victim remains in the status of forcibly disappeared.

JUDICIAL AND/OR ADMINISTRATIVE ACTIONS

In a filing made on January 21, 1974, by the Committee for Cooperation for Peace in Chile of Osorno before the Plaza Chief and the Prefect of Carabineros of Osorno, requesting that the authorities report on the situation of forcibly disappeared persons in Osorno, the case of Guillermo Peters was included.

On July 10, 1974, Frida Peters, the victim's sister, sent a letter to the Intendant of Osorno, Army Lieutenant Colonel Lizardo Abarca Maggi, requesting information on whether Guillermo Peters was still alive and his whereabouts.

She also asked for his assistance regarding a loan requested in the victim's name at the Banco del Estado branch in Osorno. In his response dated July 5, 1974, the Intendant informed Mrs. Frida Peters that "after making the appropriate inquiries with the police agencies, it has been established that said person has never been detained by Carabineros or Investigations." Regarding the loan, he informed her that it had been granted without a guarantor.

On February 7, 1980, a complaint was filed before the 1st Criminal Court of Osorno for the crimes of kidnapping and the possible homicide of Guillermo Peters. The action was directed against the Carabineros officials who apprehended the victim, Captain Adrián Fernández and Carabinero Juan Moreira.

Furthermore, the filing notes that Carabinero Juan Moreira "had recommended that the victim leave Osorno because they were going to kill him."

The National Commission for Truth and Reconciliation, through official letter No. 2086 of February 6, 1991, presented a complaint to the 1st Criminal Court of Osorno regarding the detention and subsequent disappearance of various individuals in the town of Rahue-Osorno, which occurred in the days following the military coup of September 11, 1973, in Chile.

The complaint was based on the powers granted by Supreme Decree No. 355 of May 9, 1990.

On February 18, 1991, the Judge of the aforementioned court resolved to open a summary proceeding for the reported events. The case was registered under No. 39.911-3. At that time, he summoned the relatives of the victims to testify.

On March 27, 1991, the Judge deemed it "necessary and convenient to separate the present case in order to instruct a separate summary for each of the persons identified in the complaint" presented on February 6, which is why he initiated various separate cases.

Finally, the criminal trial concluded, directed mainly against the most ruthless criminal, a serial killer who operated in a Carabineros uniform in the Los Ríos and Los Lagos regions; this is Colonel (R) Adrián José Fernández Hernández.

I knew him closely as he spent almost two years as an assistant Lieutenant at the Osorno Intendancy (71-72). From there, he rose to Captain and took over the 3rd Precinct of Rahue. Once the military coup occurred, several popular leaders chose to turn themselves in at the Rahue Precinct (upon being called by military edicts), trusting that they would be "attended to" by someone in whom they had a certain degree of confidence.

Nothing more was ever heard of them (forcibly disappeared). Fernández has been sentenced ONLY TO FIFTEEN YEARS IN PRISON for being the author of the qualified kidnapping of: 1. Santiago Domingo Aguilar Duhau, 2.

César Osvaldo del Carmen Ávila Lara, 3. José Mateo Segundo Vidal Panguilef, 4. José Ligorio Neicul Paisil, 5. Flavio Humberto Valderas Mansilla, 6. Lucio Hernán Ángulo Carrillo, 7. Jorge Ladio Altamirano Vargas, 8.

René Burdiles Almonacid, 9. Joel Fierro Inostroza, 10. José Ricardo Huenumán Huenumán, 11. Luis Sergio Aros Huichacán, 12. Arturo Jesús Valderas Angulo, 13. José Rosario Segundo Panguinamún Ailef, 14. Guillermo Ernesto Peters Casas, and 15.

Mario Fernández Acum. For also being the author of the qualified homicide of: 16. Raúl Santana Alarcón, 17. Gustavo Igor Sporman, 18. Martín Núñez Rosas, 19. Jorge Ricardo Aguilar Cubillos, 20. Edgardo Eugenio Cárdenas Gómez, and 21.

Ester Bustamante Llancamín, For also being the author of frustrated qualified homicide of Blanca Ester Valderas Garrido. For finally being the author of torture against the following political prisoners: 1.

Carlos Hurtado Gallardo, 2. Juan Bernabé Igor Sporman, 3. Luis Orlando Oliveros Angulo, 4. Luis Armando Vargas Coñuel, 5. Juan Orlando Aguilar Angulo, 6. René Orlando Llanquilef Llanquilef, 7. Eliecer Rolando Reyes Gallardo, 8.

Ida Ester Torres Santana, and 9. Leandro Sanhueza Flores. In other words, for being the author of the crime of fifteen qualified kidnappings (forcibly disappeared), author of six qualified homicides (political executions), author of another frustrated qualified homicide, and author of crimes of torture against nine political prisoners, the murderer and torturer ADRIÁN JOSÉ FERNÁNDEZ HERNÁNDEZ has been sentenced to serve only a sentence of FIFTEEN YEARS IN PRISON.

One more example of JUSTICE WITH CLEMENCY, "to the extent possible." MEANWHILE, the State of Chile has not compensated the families or the surviving victims. As a lawyer, I sponsored the complaints for the nine cases of torture included in the conviction against Fernández.

It is worth imagining that I personally could have been one more case among the forcibly disappeared. Indeed, by order of Commissioner Fernández, I was detained on 09.13.1973, at my home, in a Carabineros operation, and I spent 24 hours in the cells of the Rahue Carabineros Precinct.

The police report filed by Fernández was the reason I was convicted in a War Council in Osorno. The terrible torture to which he subjected Mr. Juan Orlando Aguilar Angulo (RIP) was intended to force him to testify, imputing terrorist actions and alleged possession of explosives to me that could justify a death sentence against me.

Fortuitous circumstances prevented it. Finally, after two years in prison, I was expelled from Chile with a sentence of banishment. I was able to return from exile, from Sweden, in 1997. The criminal Adrián Fernández Hernández is still free on bail.

On September 13, 1973, the Chief of the Entre Lagos Station, Sub-officer Germán García, took him to the Third Carabineros Precinct of Osorno, where his sidearm was taken, and he was made to go into the office of Commissioner Adrián Fernández, who accused him of being a sympathizer of the Unidad Popular because he was a friend of the sub-delegate of San Pablo, who was from the Socialist Party; he had no political activity, but for the sole fact of being his friend, he was labeled a dangerous element. He adds that at the Entre Lagos Station, several local authorities were detained, and according to what his colleagues told him, these people were taken from the Unit in a SAG van by personnel from the Third Precinct of Osorno. Captain Fernández had a group to handle political prisoners, and it was always the same people who went everywhere; they were Sergeant Aguila, Rafael Pérez Torres, Francisco Inostroza, and Bécker, who was the driver; Sketch and ocular inspection report of the Third Precinct on page 958; Document titled “The Private War of Captain Fernández” on page 1,534; Book titled “War Council” on page 1,672; Presentation by the Pro-Peace Committee on page 1,806; Report of the Truth and Reconciliation Commission on page 2,232; Complaint on page 2,477; Staffing of the First Precinct of Osorno on page 2,605; Statement by Berta del Carmen Peters Rodríguez on pages 2,835 and 3,245 and by Tomas Sánchez Palma on pages 2,838 and 3,246, who stated that on September 18, 1973, between 7:00 PM and 8:00 PM, while they were at the Kunz family home together with their 3 children and her brother and brother-in-law, the currently forcibly disappeared Guillermo Peters Casas. They were about to have dinner when they saw several vehicle lights; immediately, Guillermo said that they were surely looking for him, since the radio had requested the presentation of people who had worked for the Unidad Popular, and Guillermo Ernesto was the driver for Rubén Zapata, a Communist Party Deputy. They went to his house and were able to see that they were uniformed men whose faces were obscured by helmets; there was one who was the one giving orders to the others and had a bulky build. There were 6 to 8 Carabineros who were moving in vehicles, vans. The official giving the orders spoke to Guillermo Ernesto and ordered him to get into the back of the van, telling him that the Deputy's Citroneta would be taken to Osorno by a Carabinero. Guillermo Ernesto was not beaten, nor was he tied up or handcuffed. From that date, the search for Guillermo Ernesto began at the Third Precinct, where they informed them that he was not there and where they informed them that it was possible he was at the Estadio Español or the Regional Hospital, but they did not obtain positive results. They point out that a week later, information appeared in the newspaper La Prensa that the Citroneta had been found abandoned in Pilauco, which they find irrational because the Citroneta was brought from their house by Carabineros and therefore could not have appeared abandoned; Statement by María Nolfa Casas Barros on pages 2,840 and 3,226, who indicated that Guillermo Ernesto Peters Casas was her son, that he lived with her, and on September 11, 1973, he was the driver for the Communist deputy Rubén Zapata, and as far as she knows, he was not registered in the Communist Party. On September 17, 1973, her son got up early and went to the countryside to his sister Berta Peters Rodríguez's house, where they were going to spend the 18th festivities, while she and her daughters were going to go on the 18th; that was the last time she saw her son. She does not remember if on September 17 or 18, 1973, about 4 Carabineros arrived at her house, who asked for her son and to whom she said that he had gone to Chahuilco. Later, her daughter Berta notified her, she does not remember if by phone or in person, that the Carabineros had gone to detain Guillermo Ernesto, and that the Carabineros had taken the Citroneta that Guillermo was driving; since then, they began to search for her son without positive results. At that date, he was 18 years old, single, and had no children. A few days later, through the newspaper, they learned that the Citroneta had appeared on a road toward the coast. She believes her son was detained for the sole fact of working with Rubén Zapata because he did not get involved in riots and did not attend meetings, as he would wait in the Citroneta for his boss to arrive; Statement by Frida Elizabeth Peters Casas on pages 2,842 and 3,222, who indicated that by September 11, 1973, she lived with her mother, sister, and brother Guillermo Ernesto Peters Casas. On September 17, 1973, they sent her brother Guillermo Ernesto to the countryside to her sister Berta Peters Rodríguez's house, as they always spent the 18th together in the countryside; her brother left in the Citroneta that was under his charge. That same day, about three Carabineros arrived at their house to ask for her brother, and since she was suspicious, she did not tell them where he was, but later she found out that they had returned later and her mother had told them that "Viller" was in Chahuilco at her sister Berta's house. She does not remember if on the same day or the next day her sister notified them that Carabineros had detained her brother. That was how they began the search for her brother, and they never gave her answers about his whereabouts. She thinks that the Carabineros of the Third Precinct were the ones who detained her brother because when they asked for him, they would get nervous. Regarding the Citroneta, a few days later they learned through the newspaper La Prensa that it had appeared abandoned toward the coast; in any case, she saw the Citroneta on two occasions in the city driven by uniformed Carabineros whom she did not identify; Photograph belonging to Guillermo Ernesto Peters Casas on pages 2,881 and 3,210; Testimony of Edith Almerinda Peters Casas on page 2,882, who indicated that on September 18, 1973, Carabineros detained her brother Guillermo Ernesto Peters Casas in the Chahuilco sector. She assumes it was her sister Berta who notified them of what happened. The first efforts to try to locate her brother were carried out by her mother together with her sister Frida; she intervened later, years later, when the Rettig Commission began. She never saw the Citroneta her brother was driving again; through the newspaper, they learned that it had been found dumped near Murrinumo; in any case, her sister Berta told them that when they detained her brother, the Carabineros had taken the Citroneta; Birth certificate belonging to Guillermo Ernesto Peters Casas on page 3,211; Report from the Civil Registry Service on page 3,224; Report from International Police on page 3,234; Testimony of Roberto Germán Peters Casas on pages 3,241 and 7,932, who indicated that by 1973 he did not have much contact with his family since he worked on buses and was not in Osorno; he also did not deal much with his brother Guillermo Ernesto since he had different political ideas than his own; he worked as a driver for Deputy Rubén Zapata. According to what his mother told him, for the military coup, Guillermo had gone to Chahuilco to his sister Berta's house, a place where Captain Fernández and a group of Carabineros arrived and detained his brother, whom they put into a van, and the Citroneta that was under his charge had been taken by a Carabinero. About three days after his detention, it appeared in the newspaper that they had found Deputy Zapata's Citroneta abandoned on the road to the coast and that the driver was not found. He points out that on the same day that Guillermo Ernesto's detention occurred, at about 9:00 PM, Carabinero Juan Moreira, who was a friend of the family, especially of his, arrived at his house and warned him that Captain Fernández and other Carabineros had gone to look for Guillermo at the country house; statements he confirmed the next day when his sister from the countryside notified them of the detention; Testimony of Marita Iris Schmith Sánchez on page 3,245 vta, who indicated that on September 18, 1973, between 7:00 PM and 8:00 PM, while they were visiting Berta Peters, her husband, and brother at her house, they saw lights illuminating the surroundings, so Berta went to her house, about 100 meters from hers; immediately, her brother Guillermo left, as he said that surely it was him they were looking for. A while later, two Carabineros appeared at her house and asked her what Guillermo was doing at her house, to which she replied that he was visiting. Finally, she said that Guillermo did not talk about politics; Testimony of Enrique Kunz Otterstein on pages 3,246 vta and 5,461, who indicated that on September 18, 1973, between 7:00 PM and 8:00 PM, while he was at his house located in Chahuilco, Fundo El Cobre, and his neighbors Tomás Sánchez, his wife Berta, and her brother Guillermo Peters were visiting; a van with six Carabineros arrived. His neighbors went to check their house, and immediately Guillermo took his jacket, saying not to worry, that it was him they were looking for. Carabineros superficially searched his house before leaving, put Guillermo in a van, and took the Citroneta. He did not identify any Carabinero because they were wearing campaign uniforms with helmets, and it was night; Version of Enrique Segundo Kunz Schmidt on page 3,247, who stated that on September 18, 1973, he was at his parents' house in Fundo El Cobre in Chahuilco; also present were neighbor Berta Peters, her husband Tomás Sánchez, and a brother of the neighbor named Guillermo Peters, with whom he was friends and who had arrived the day before at his sister's house. It was then that, near 8:00 PM, they saw vehicle lights at Tomás Sánchez's house, and he asked Guillermo what was happening, since they knew he was from the Communist Party because he was Rubén Zapata's secretary, noting that everything was solved and that he had gone to the Regiment; in view of this, he told him to stay there and that he and Tomás would go to see what was happening. Upon arriving at the house, they encountered six Carabineros with rifles in hand and in uniform, who detained them and asked for Guillermo, who arrived shortly after to surrender. They put Guillermo into a van, and the Citroneta was taken by a Carabinero. He did not know any of the Carabineros who were there that day. He does not know Captain Fernández, but he did hear the officials call one of them Captain; Investigation order on page 3,252; List of relatives of forcibly disappeared detainees with DNA tests on page 4,185; Newspaper publication titled “Abandoned Citroneta had been used by Rubén Zapata” on page 4,992; Statement by Emilia Brunilda Kunz Schmidt on page 5,458, who stated that on September 18, 1973, while she was at the house of her parents Enrique and Iris, together with her neighbor Berta, her husband Tomas, and her brother named Guillermo Peters, celebrating the 18th of September, around 9:00 PM they noticed there were lights at Berta's house, so they went to see. Upon arriving, they saw a dark green, closed van and two Carabineros who asked her for “Vile.” There were about five Carabineros whom she did not identify because they had helmets. The Carabineros finally put Guillermo into the van; she does not remember seeing this situation, but they told her about it, and a Carabinero took the Citroneta that he came to pick up at Berta's house. She understands that Guillermo was from the Communist Party and that he had arrived the day before his detention at his sister Berta's house; Testimony of Rubén Zapata Bravo on page 5,628, who said he had known Guillermo Peters Casas as a militant of the Communist Party; he was a very young person who was not over 25 years old. After some evaluations carried out by the regional Directorate, this young man was authorized to drive the Communist Party Citroneta provided for his service in his capacity as a candidate and subsequently as a Deputy. This person was of great conviction, loyal, and was dedicated to political work. The version he heard about his disappearance is that he was fleeing to San Juan de La Costa and that he had gone off a cliff and that he had fled, leaving the Citroneta behind.
