Nearly fifty years after Argentina’s last military dictatorship unleashed a campaign of repression that left tens of thousands missing, forensic experts have identified the remains of twelve people who were forcibly disappeared. The discovery was made at the site of the former La Perla clandestine detention center in Córdoba province, one of the most notorious facilities used by the regime during its rule between 1976 and 1983.
The identification was confirmed by the Federal Justice of Córdoba, which reported that the remains were found during search operations conducted in 2025 at the Military Garrison of La Calera, where the La Perla detention center once operated. Authorities say the discovery represents a major step forward in the country’s long pursuit of truth and accountability for crimes committed during the dictatorship.
The breakthrough comes as Argentina marks the 50th anniversary of the military coup that ushered in a brutal era of state repression. An estimated 30,000 people were forcibly disappeared during those years, many abducted by security forces and never seen again.
The identification of the twelve victims was carried out by the Argentine Forensic Anthropology Team, a group internationally recognized for its work uncovering and identifying victims of human rights abuses. The team confirmed the identities through DNA testing that matched genetic profiles from recovered remains with samples stored in the National Genetic Data Bank.
The remains had been located in a mass grave within the area once occupied by the detention center, reinforcing long-standing evidence that La Perla served as a key site in the regime’s system of illegal detention, torture, and extermination.
For the families of the disappeared, the findings bring both anguish and long-awaited clarity. Decades of uncertainty have defined the lives of relatives who have searched for answers since their loved ones vanished during the dictatorship.
Federal Judge Miguel Hugo Vaca Narvaja, who is overseeing the case, confirmed that the court will keep the victims’ names confidential until their families are privately notified. Authorities say this process is intended to ensure respect and dignity for those directly affected by the discovery.
Judicial officials indicated that once all families have been contacted and consent has been obtained, a press conference is expected between Friday and the following Monday to publicly announce the identities of the victims.
Public Prosecutor Facundo Trotta described the identifications as a significant step in confronting the legacy of state terrorism in Argentina. Court documents described the findings as “partial results,” suggesting that investigators may still be working to identify additional victims linked to the site.
The discovery is the result of a painstaking investigation that has spanned more than two decades. Forensic anthropologists and researchers combined survivor testimonies, historical documentation, and advanced technological analysis to determine where clandestine burials may have occurred within the vast military complex.
Investigators examined statements from former detainees and even former military personnel, cross-referencing these accounts with satellite imagery and advanced terrain-mapping techniques. One key tool was Light Detection and Ranging technology, known as LiDAR, which uses laser pulses to create precise three-dimensional maps of landscapes and reveal subtle changes in the terrain.
Historical aerial photographs played a crucial role in narrowing down the search area. Investigators analyzed images taken in 1979 that showed signs of disturbed soil within the military compound. These photographs were provided by the cadastral office of the provincial municipality and examined jointly with experts from the Forensic Geology Team at the National University of Río Cuarto.
By combining those photographs with testimony and geological analysis, researchers identified priority areas where clandestine burials were likely to have taken place. In 2024, investigators mapped twenty-three areas of interest and began excavation work across a sector covering approximately ten thousand square meters.
Although the excavations initially did not recover objects directly tied to the victims, investigators documented extensive evidence of human alteration of the soil, indicating past disturbances consistent with burial and exhumation activities.
Further analysis strengthened the hypothesis that bodies buried at the site had been mechanically exhumed before the 1979 aerial photographs were taken. According to the investigative team’s reconstruction, the movement of earth during those operations left subtle traces that remained visible in the images decades later.
Researchers believe these exhumation efforts were part of a broader attempt by the military authorities to conceal evidence of mass killings before the arrival of international investigators. The reconstruction of events suggested that some bodies may have been removed months before the Inter-American Commission on Human Rights visited Argentina to investigate allegations of abuses.
The search for evidence has since expanded beyond the original excavation zone. A second plot of land covering ten hectares was added to the investigation after geophysical analysis revealed soil disturbances consistent with clandestine burials and subsequent exhumations.
Authorities confirmed that the formal identification process for the recovered remains is ongoing. Once examinations and family notifications are complete, investigators are expected to release additional details about the victims and their possible connections to the network of repression centered around La Perla.
The existence of human remains at the former detention center was first confirmed by federal authorities on September 26 of last year. It was the first time physical evidence had been discovered at the site since the dictatorship ended, nearly five decades after the crimes were committed.
During the years of military rule, La Perla operated as one of the regime’s largest clandestine detention centers. Located on land belonging to the Third Army Corps and run through the Intelligence Detachment 141 in Córdoba province, it became a central hub in the dictatorship’s machinery of repression.
Investigations conducted by the Provincial Archive of Memory estimate that between 2,200 and 2,500 people were detained there between 1976 and 1978. Most of them remain missing.
Evidence of the methods used at the site has surfaced in various testimonies over the years. In 2004, Lieutenant Colonel Guillermo Enrique Bruno Laborda acknowledged in a formal complaint related to his military promotion that he had participated in operations at La Perla and had been involved in executions. According to his account, bodies were thrown into wells and burned after the killings. He also stated that he took part in removing corpses from the site in 1979.
