Liliana Pereyra's skeletal reconstruction, about 1985. Between 1976 and 1983, Argentina's military regime committed massive human rights violations. Nearly 20,000 men, women and children were "disappeared" (los desaparecidos), abducted, tortured, raped, and murdered, with no information provided on their whereabouts. In 1984, anthropologist Clyde Snow recruited a group of Argentinean university students who lacked training in forensics, but were eager to learn. Together, they excavated hundreds of clandestine mass graves. "Once the bones arrive in the laboratory... We arrange them in what we call "anatomical order" just as if the person was lying on the table, with... her arms extended... then we begin our more detailed examination of the bones." Clyde Snow.
