The Last Nazis - Season 1 Episode 1 The Hunt for Dr Death

In the autumn of 1941, a young Austrian doctor called Aribert Heim was assigned to the Mauthausen Concentration Camp. In just six weeks, he murdered hundreds of inmates by carrying out horrific and needless experiments. He evaded capture and has never answered for his crimes - but now 60 years on and with Heim well into his 90s, fresh evidence has emerged suggesting that he might still be alive.
