Nazi hunters are relying on an advertising campaign in southern Chile to provide information on the whereabouts of Aribert Heim, known as "Dr. Death."
Heim, the most notorious member of the Third Reich still believed to be alive, passed his 94th birthday on June 28 if he is still alive. He documented the hundreds of victims he himself murdered and tortured at the Mauthausen concentration camp in Austria during World War II.
The Nazi hunters believe he is hiding out in the Patagonia region of southern Chile, also home to his daughter.
"In the last few days we've received information from two different sources, both relating to Chile, which we think have very good potential," said Efraim Zuroff, director of the Israel office of the Simon Wiesenthal Center which is hunting for Heim and hundreds of other suspected Nazis.
The group has put up a 495,000 U.S. dollar reward for information leading to the arrest of Heim, known to have decorated his office during the war with human body parts, even using the skull of a man he decapitated as a paperweight.
Zuroff and his team will fly Wednesday to Puerto Montt, a town 657 miles south of the capital Santiago where Heim's daughter lives. The visit is part of what they call Operation Last Chance, which will include a newspaper advertising campaign in local newspapers in Chile and Argentina.
Zuroff said most evidence suggests Heim is alive. His children have not taken possession of a 1.9 million dollar bank account in his name in Berlin, which would be theirs if they could present proof of his death. They would also have access to some 1.26 million dollars in stocks and bonds if Heim were proven dead.
An Austrian who killed hundreds of inmates by injecting gasoline or poison in their hearts, Heim has been on the run since evading police in Germany in 1962 prior to a planned prosecution.
