In this article, the author reflects on her experience as part of the Research Group on Social and Forensic Anthropology (GIASF) in following the search for relatives of the disappeared. The work with “Las Buscadoras de El Fuerte” is analyzed, an organization that, like many in Mexico, is made up mostly of mothers and wives of disappeared persons who, given the inability of the Mexican State, have given themselves the task of searching for human remains of their relatives in clandestine graves. Based on testimonies and ethnographic registration, the limits and possibilities of feminist legal anthropology are analyzed for the co-production of knowledge that are useful in contexts of multiple violence and impunity.
