On 9/4/1976 Time: Between 08:00 and 08:15. Location: Laguna Garzón, Paraje Las Garzas. Found by: Pedro Moreira Olid, on the seashore. He was face down, with a piece of cloth attached to one of his wrists and his eyes blindfolded by another that wrapped around his entire head and was knotted.1 “The hands were tied with a piece of blue cloth and the eyes were tightly blindfolded with a piece of orange cloth.” 2 Autopsy.

First inspection of the body: Carried out by Justice of the Peace Sandra Presa, the Sub-Officer in charge of the National Naval Prefecture (P.N.N.) Artemio Pereyra, and Dr. Mario Katz. The body showed hematomas and wounds; both arms were broken and there were multiple hematomas on the face. “(…) He presents a series of hematomas and wounds, especially on the left shoulder, left flank, and lumbosacral region; similar lesions of lesser intensity are also observed on the shoulder; both arms are broken (...).

Once the latter (the face blindfold) was removed, it was confirmed that the face had multiple hematomas on both cheeks, the nasal region, and the lips.”3 The primary diagnosis, according to the report prepared by Justice of the Peace Sandra Presa, indicates that he was “savagely beaten, killed, and thrown into the water, as he did not present the characteristic foam fungus.”4 It indicates that death occurred before immersion and that it was due to the multiple traumas received.

The first report by Dr. Katz notes that the corpse belonged to an individual of Oriental race: Due to the features (flattened nose and thick lips and presumed skin color) and build, it can be said that it was an individual of Oriental race.5 The Judiciary ordered an autopsy to be performed at the morgue of the Departmental Center.

Clinical examination: Performed at the morgue of the Rocha Central Hospital by the Police Doctor, Dr. Mario Katz. The autopsy was not performed because the corpses (N.N. 1 and N.N. 2, who has not been identified) were in an advanced state of decomposition, as noted by Dr.

Katz in his report. “(…) The clinical examination shows a body in an advanced state of decomposition (...) with multiple erosions and superficial and deep wounds on both shoulders, a large number of hematomas, and fractures of both arms.

The upper part of the face was firmly tightened with a wide bandage tied at the back, which, once removed, showed deep lesions (...).” Significant edema of the scrotum and limbs. The lack of the classic “foam fungus” in the mouth and nostrils, which certifies death by immersion, is noteworthy.6 Historical Investigation Team 09/17/2012.

Relatos de los Hechos

The Human Rights Secretariat of the Presidency announced yesterday the identification of another of the bodies found on the coasts of Rocha in 1976. It is Nelson Valentín Cabello Pérez, a Chilean citizen, textile worker, and militant of the Revolutionary Workers' Party (Partido Revolucionario de los Trabajadores), who was detained in Buenos Aires along with his partner Nora Madikian, who remains forcibly disappeared, reported the coordinator of the Secretariat, Graciela Jorge.

At that time, several corpses appeared, tied and with signs of torture, on the Uruguayan coast. The authorities of the time said they were Koreans or Asians who had fallen from ships passing through the area.

Months ago, another identification was achieved, as in this case, by fingerprint comparison. “It is clear that he was part of the death flights; he was thrown into the sea and the currents brought him to our coasts,” explained the coordinator.

On the other hand, Graciela Jorge announced that excavations in La Tablada will soon resume. New information has emerged that justifies resuming search work in that place, she noted. Jorge also reported that work will continue in Battalion 14, although the search location has been moved.

As reported by LA REPÚBLICA, the new location will be at the back of the shooting range, 300 meters from the place where Julio Castro and Ricardo Blanco were found. The coordinator also revealed that four new reports on disappeared persons were received and that a check and investigation will be carried out.

On the initiative of his relatives, neighbors, and friends, the place was recovered to create a space for memory and the defense of human rights. The "Nelson Valentín Cabello Pérez" House of Memory, located at Boedo 1870, Bernal, was inaugurated this Saturday, an initiative of relatives and friends from the La Cañada neighborhood who decided to recover the place and generate a space for participation and dialogue for the community.

Representing the Mayor of Quilmes, Francisco Gutiérrez, the Undersecretary of Human Rights, Lila Mannuwal, participated in the act along with a significant turnout of relatives, neighbors, colleagues, and friends, who highlighted the importance of promoting collective memory about recent history and contributing to the search for truth and justice. “It is a very important day for Quilmes because it has a history of great resistance, struggle, and so many disappeared persons; we are inaugurating the first House of Memory for Nelson Cabello.

It is unusual because it is an initiative of the comrades themselves, and neighbors collaborated so that this place, which had been flooded and unoccupied since Nelson was taken, was little by little recovered by the family, and they said what better destination than to give a place to the memory of Nelson,” said the undersecretary.

A space for rights Mannuwal reiterated the need to continue working to recover the rights of today. “May it be a reference place for neighbors for the human rights of today; people who have needs will come here, and through us, we will provide them with material from all areas of the municipality to advise them, as a place for the rights of the neighbors.

I hope we have a chain effect and each relative can make a place to remember the disappeared person and also work for the rights of today.” “In this neighborhood, 19 comrades disappeared, all kids. This must be disseminated so that it is known and valued,” she concluded.

At the inauguration, a poem dedicated to Nelson Cabello was read, and a commemorative plaque was unveiled. The Director of Memory and Justice of the Undersecretariat of Human Rights of Quilmes, María Laura Rolón, also participated in the meeting and highlighted the presence of the granddaughter, recovered by the Grandmothers of Plaza de Mayo, Carla Artés, who had been kidnapped at 10 months old and appropriated by an intelligence agent who had been part of the Triple A.

Nelson Cabello, Present Nelson was born in Chile in 1953. He came to Argentina with his family and lived in a humble little house on Boedo Street No. 1870 in the La Cañada neighborhood, Bernal. Elena and Don Sergio, his parents, had five children.

Nelson was the third. As a child, he showed commitment to everything he did; he left life lessons to those who knew him, especially his siblings, Graciela, Lorenzo, Gustavo, and Ricardo. He was 23 years old when he was detained on April 9, 1976, by security agencies in Valentina Alsina, along with his wife Nora Beatriz Mardiquián Bogosián (21 years old) and his brother-in-law Juan Carlos Mardiquián Bogosián (18 years old), who still remain forcibly disappeared.

Later, the family suffered the detention of the youngest of their brothers, Ricardo Cabello (14 years old), who, after remaining a victim of political imprisonment and torture, was released years later.

Nelson's remains appeared 20 days after his kidnapping on the coasts of Rocha in Uruguay. The identification process began with an investigation initiated through the arduous task being carried out by the Argentine Forensic Anthropology Team.

For all these years, his remains were unidentified, until Thursday, November 15, 2012, when Human Rights authorities confirmed the news. The assassination of Nelson Cabello confirms that he was thrown into the sea in the death flights in 1976.

And after 37 years, his family does not abandon the fight in the search for Truth, Memory, and Justice for Nelson, his partner Nora, and Juan Carlos, who remain forcibly disappeared. Neighbors, relatives, colleagues, and friends call to participate in the Opening. The "Nelson Valentín Cabello Pérez" House of Memory, in homage to the comrade, popular militant, Detained and Disappeared.

Condor Plan: new body found in Rocha in 1976 identified, belongs to Chilean Nelson Valentín Cabello Pérez

The Secretariat for Monitoring of the Commission for Peace reported that another of the bodies found on the coasts of Rocha in 1976 was identified; in this case, it is the remains of a Chilean citizen, Nelson Valentín Cabello Pérez, who was a victim of one of the “death flights” of the Condor Plan.

Likewise, the restart of excavations in Battalion 14 was announced. After research and dactylographic verification work, the Commission identified the body found on the coasts of Rocha in 1976 as that of Nelson Valentín Cabello Pérez, a Chilean citizen who disappeared in Buenos Aires at age 23 along with his pregnant wife and his brother-in-law.

His body was found 20 days after he was thrown into the sea, and the strongest hypothesis involves him in the “death flights” within the framework of the Condor Plan of repressive coordination between the countries of the Southern Cone.

The Chilean citizen is part of the same group of disappeared persons, along with Luis Guillermo Vegas Zeballos, whose identification was announced by the Secretariat last September. Cabello Pérez, like Vegas Zeballos, was a militant of the Revolutionary Workers' Party.

The general coordinator of the Secretariat for Monitoring of the Commission for Peace, Graciela Jorge, and Eduardo Pirotto, delegate for the relatives, reported that Nelson Valentín Cabello Pérez, born in Santiago, Chile, in 1953, was 23 years old and was a worker in Argentina when he was detained in Lanús, Buenos Aires, along with his wife Nora Beatriz Mardiquián Bogosián, who was pregnant, and his brother-in-law, Juan Carlos Mardiquián Bogosián, who still remain forcibly disappeared.
