In Search of..... S03E18 - The Angel of Death (aka Joseph Mengele)

Angel of Death: Nazi hunter Simon Wiesenthal tracks infamous war criminal Josef Mengele to his hiding place in Paraguay.

Mengele is believed to have died only six days after this episode was broadcast, having drowned as a result of a stroke while swimming. At the time of his death, his identity was not widely known.

Years after this installment was initially transmitted, Mengele's remains were found and identified; he proved to have had to eke out a bare existence as a farm worker, and his punishment for his war crimes was to have lived out the rest of his days in both comparative obscurity and the fear of eventual discovery.
