Aribert Heim
Aribert Ferdinand Heim (28 June 1914 – 10 August 1992) was an Austrian doctor, also known as Dr. Death. As an SS doctor in a Nazi concentration camp in Mauthausen, he was accused of killing and torturing many inmates by various methods, such as direct injections of toxic compounds into the hearts of his victims. He lived for many years in Cairo, Egypt under the alias of Tarek Farid Hussein and died there on 10 August 1992. In 2009, a BBC documentary stated that German police had found no evidence of Heim's death on their recent visit to Cairo; however, three years later, a court in Baden-Baden confirmed that Heim had died in 1992, based on evidence provided by his family and lawyer.
