Adolf Eichmann, who oversaw the transport of Jews across Europe to concentration camps, was abducted by Israeli agents in Argentina in 1960 and hanged in 1962. Josef Mengele, known as the "Angel of Death" for his ghoulish experiments at Auschwitz, spent most of his postwar life in Argentina before dying in Brazil in 1979. Klaus Barbie -- "the Butcher of Lyon" -- was extradited from Bolivia in 1983 to France, where he died in prison, and Eduard Roschmann -- "the Butcher of Riga" -- died in Paraguay in 1977.

[Aribert Heim] has a daughter in Chile and is believed by [Efraim Zuroff] and others to be alive in either Chile or Argentina. Although Heim's family has said he is dead, German authorities have discovered a bank account with more than $1.5 million that could be claimed by his children if they were to offer proof of his death. They haven't, and now, believing that the account might still be financing Heim, Germany has created a special task force to track him.
