During Argentina's "Dirty War" between 1976 and 1983, the military regime committed heinous crimes against humanity, including the disappearance of nearly 20,000 people who were abducted, tortured, raped, and murdered with no information given about their whereabouts. After the junta fell, the American Association for the Advancement of Science sent forensic scientists to aid in the investigation since many Argentine forensic professionals were involved in the crimes, associated with the state, or poorly trained. Anthropologist Clyde Snow recruited Argentine university students to excavate hundreds of mass graves, leading to the formation of the Argentine Forensic Anthropology Team, which is dedicated to using forensic science to investigate human rights abuses. In 1985, the forensic testimony helped convict six of nine former Argentine military junta leaders for the deaths of the "disappeared," including the case of Liliana Pereyra, a young woman who was abducted, tortured, raped, and murdered, and whose child's identity and whereabouts are still unknown.
