He was on the top Israeli list of the most wanted for war crimes against the Jews in World War II, and the Israeli Nazi hunters offered huge amounts of money for his arrest. He is Aribert Heim, who moved to live in Egypt under the name of Tarek Farid Hussein after he converted to Islam. He died of cancer on August 10, 1992. According to the German News Agency, Dr. Death killed 300 people detained in the Mauthausen concentration camp in northern Austria by injecting them directly in the heart with poison, oil or water, after amputating their organs without anesthetic so as to measure their ability to bear pain. While it was thought he had escaped to Chile, where his daughter lived, or to Denmark, Spain or Argentina, an official in Baden-Wuerttemberg said the German authorities got information that Heim lived in Egypt from 1963 until his death in 1992. The International Herald Tribune said Heim was a member of the SS forces of Hitler. It said he was a tall man who used to jog for 25 kilometers everyday in the crowded streets of Cairo until he would reach Groppi to buy sweets for his friends and their children. It said his friends thought he was an amateur photographer because he always had a camera on him. The paper also said that Heim had kept a skull of one of his victims as a souvenir, and that The New York Times and ZDF got hold of a dusty bag with rusty locks that was found in his hotel room in Cairo, pointing out that the bag contains documents that tell the man's story in Egypt. ZDF said Heim used to irregularly get money from his sister in Berlin, and that he donated his body for medical research after his death. Meanwhile, the Wiesenthal Center for hunting Nazi war criminals expressed doubts about reports of his death in Cairo.
