In 1985, American, Brazilian and West German scientists announced that skeletal remains exhumed from a graveyard in Brazil were those of Nazi war criminal Dr. Josef Mengele.
Argentina has created a special bureau to track down any remaining Nazi war criminals hiding in a country that was once the refuge of top Nazis like Josef Mengele.
Mengele decided who would work and who would die and became notorious for his medical experiments on prisoners and his ruthless selection process, according to the United States Holocaust Memorial Museum.
