Interdisciplinary Group of Independent Experts (GIEI)


The Interdisciplinary Group of Independent Experts (GIEI) was created in November 2014 through an agreement between the IACHR, the Mexican State, and representatives of the disappeared students in Ayotzinapa. This agreement also established the main activities to be carried out by the GIEI: to draw up plans for searching for the disappeared persons alive; technical analysis of the lines of investigation to determine criminal liabilities; and technical analysis of the Plan for Integral Attention to the Victims (Plan de Atención Integral a las Víctimas) of the events of September 26 and 27, 2014.

The GIEI is comprised of Carlos Martín Beristain, Angela Buitrago, Francisco Cox Vial, Claudia Paz y Paz and Alejandro Valencia Villa.

Argentine Forensic Anthropology Team (EAAF)

The Argentine Forensic Anthropology Team (EAAF) carried out the tasks of documentation and recovery of biological and non-biological evidence in the municipal trash dump in the town of Cocula, Guerrero. Over 18 months of collection and multidisciplinary analysis of the physical evidence from the Cocula landfill revealed that no scientific evidence was found to support the supposed incineration of the 43 students on the night of September 26-27, 2014 in that location, disputing the "historic truth" of the Mexican government. 

This conclusion was presented by the EAAF at their press conference on February 9, 2016, and in the following comprehensive report (click image to view pdf)

Since 1984, the EAAF has accompanied families of victims of enforced disappearance around the world in the search, identification, and restitution of the remains of their loved ones, placing science at the service of truth and justice. The EAAF has been nominated for the 2020 Nobel Peace Prize.


The Ayotzinapa Case: A Cartography Of Violence

Project by Forensic Architecture commissioned by and undertaken in collaboration with the Equipo Argentino de Antropologia Forense (EAAF), Centro de Derechos Humanos Miguel Agustín Pro Juárez (Centro Prodh) and University Museum for Contemporary Art (MUAC) for the families of the 43 disappeared, the wounded and killed students.

An interactive cartographic platform visualizes, for the first time, the attacks on the night of 26-27 September 2014 that led to the disappearance of the 43 students from the Rural Normal School of Ayotzinapa in the town of Iguala, Guerrero, Mexico.

Using interactive maps and 3D reconstructions, the platforms reveals:

  • The progression, escalation and geographic spread of the violence during the attacks

  • The level of coordination and collusion between state agencies and organized crime

  • The extent of the disruption and distortion of evidence by state agencies
