Host Maria Hinojosa talks with Mercedes Doretti, a world leader in using forensic anthropology and archeology to investigate human rights violations. Doretti is the co-founder of the Argentine Forensic Anthropology Team. From Indonesia to Congo, from El Salvador to Croatia, Doretti's organization has worked at every known location of genocide and mass killings.
