Leading Nazi hunter Efraim Zuroff said Monday that leads indicate that Aribert Heim, the infamous sadistic "Doctor Death," was still alive and in southern Argentina or Chile.
"There is no evidence that he is dead, but, to the contrary, there are numerous leads that he could be alive in this region," said Zuroff, director of the Simon Wiesenthal Center, which has sought Nazi fugitives since 1945.
Zuroff told reporters in this resort town in southwestern Argentina that a key to the investigation is the location of Heim's daughter, Waltraud Diharce, who lives in the Chilean town of Puerto Montt.
"From there he traveled to Bariloche 50 times in one year," he said. The two towns are 350 kilometers (215 miles) apart.
An Austrian doctor, Heim, who would now be 94, is wanted for killing hundreds of concentration camp victims with his horrific medical experiments, including performing operations without anesthesia and injecting gasoline directly into their hearts.
