In 2014, the Interdisciplinary Group of Archeology and Anthropology Investigations Laboratory of Tucumán (LIGIAAT) was summoned by the Federal Court of Presidencia Roque Sáenz Peña (Chaco) to carry out expert tasks on the property where the ex-Mayoralty operated, denounced as a clandestine center of detention. On that occasion, they conducted interviews and excavations on the property, preparing a detailed report on what had been done and raising the need to monitor the work during sediment movements on the ground in order to provide data on the use of the building as well as the possibility of finding clandestine burials.
In 2021 they were summoned again by the Secretariat of Human Rights and Gender of Chaco, due to the start of construction by the Pro.Cre.Ar plan, where they presented a work plan to carry out investigation tasks in the areas of soil removal. Parallel to this activity, they signed an agreement with the Human Rights and Gender Secretariat of Chaco, UNCAUS, the Provincial Commission for Memory, the Single Registry for Truth and the Multisectoral Registry for Memory. This agreement was developed to carry out training sessions, courses, conferences, research work and the collection of data and testimonies.
