Exhumation and Identification of Mengele’s Remains

The exhumation and identification of Josef Mengele’s remains in Brazil in 1985 resolved the central uncertainty of a decades-long manhunt: whether the fugitive war criminal was dead and whether his body lay in a grave under another man’s name. The answer emerged through a chain of police investigation, informant disclosures, and forensic comparison. The remains were identified as Mengele’s with reasonable scientific certainty in June 1985, then confirmed by DNA tests in 1992. The process exposed the support network that had helped conceal him, while the final disposition of the remains left him without a grave.

The trail to Brazil

The investigation gained momentum after Hans Sedlmeier, a longtime associate, disclosed during a dinner in the Black Forest in autumn 1984 that he had continued sending money to Mengele. The disclosure reached the police, who issued a mandate. On 10 May 1985, a German prosecutor informed American and Israeli partners that Sedlmeier’s home was to be searched. This time, local police in Günzburg did not warn him in advance.

Search and disclosure

At the end of May, police searched Sedlmeier’s luxurious villa. In his wife’s dressing room they found an address book, coded telephone numbers, and photocopied correspondence involving Mengele, Wolfram Bossert, and the Stammers. One of Bossert’s letters reported that Mengele had died. Sedlmeier refused to cooperate and was placed under house arrest while investigators worked through the coded contacts. The address book pointed to Brazil.

São Paulo police then kept the Bossert and Stammer families under continuous surveillance for four days. They found no sign of Mengele. On 5 June, officers raided the Bosserts’ home at dawn. Among the belongings were trinkets and recent photographs of an older, moustachioed man, evidence of the family’s connection to Mengele. Bossert disclosed that Mengele was dead and buried in Embu cemetery, in a vault under the name Wolfgang Gerhard.

Gitta Stammer acknowledged recognizing the man in a photograph but identified him as Peter Hochbichler, a Swiss man who had managed the family’s farms for years and had been introduced to them by Gerhard. She denied knowing anyone named Josef Mengele. Her husband, Geza Stammer, was away on a cruise in Asia and was not questioned at that time. The different accounts underscored how much the investigation still depended on separating aliases, personal connections, and deliberate concealment.

Exhumation and forensic identification

On 6 June, news of the discovery reached the press, and a large crowd of cameras, photographers, and microphones gathered as police and members of the Bossert family watched the grave opened in Embu das Artes. The coffin was raised and opened, and the skeleton was exposed. The public spectacle made the discovery visible, but the grave itself could not settle the question of identity. Forensic specialists from several countries came to Brazil to examine the remains.

The identification rested on multiple comparisons rather than a single feature. Experts determined the skeleton’s blood group, recovered hair from the head and moustache, took a fingerprint, and measured the bones, including the gap between the upper front teeth. They examined the vertebrae and femurs, as well as a hole in the left cheekbone and the prominent forehead. Photographs of Mengele at younger and older ages were superimposed for comparison. Investigators also consulted his SS file, which recorded a pelvic fracture after a motorcycle accident at Auschwitz. Together, the biological, anatomical, photographic, and documentary evidence provided a converging case for the remains’ identity.

Skepticism persisted while the examination proceeded. The Israelis and the Klarsfelds questioned why Mengele’s family had remained silent for six years and why the disclosure had come when it did; they suspected another attempt to obscure his fate and allow him to remain at liberty. Simon Wiesenthal was also unconvinced, recalling repeated false reports of the war criminal’s death in different countries. The history of such mistaken claims made independent forensic verification essential.

Confirmation and aftermath

On 21 June 1985, forensic pathologists at police headquarters in São Paulo announced that the skeleton from Embu had been identified as Josef Mengele’s to a reasonable degree of scientific certainty. DNA tests in 1992 confirmed the experts’ conclusion. That year, Germany, Israel, and the United States definitively closed the Mengele case. The remains were stored in a cupboard at São Paulo’s Legal Medical Institute, and the family did not claim them. The identification therefore ended the question of where Mengele’s body was, but it did not give him a burial place.

The discovery also brought the family’s role into public view. Rolf had initially considered selling his father’s letters and notebooks, as well as photographs from his trip to Brazil, to Stern magazine; he instead donated them to Bunte. Proceeds from issue sales were to go to associations of concentration-camp survivors. Its 18 June issue reported that the family had known where Mengele was hiding and supported him financially. Rolf confirmed that his father had died in Brazil in 1979 and expressed sympathy to victims and their loved ones, while saying he had withheld the death out of consideration for those who helped his father. He did not address Mengele’s atrocities; Dieter, Karl-Heinz, and Sedlmeier remained silent.

The case did not lead to prosecutions of Dieter, Karl-Heinz, Sedlmeier, or Rolf. In Germany, the charge of aiding, abetting, or counselling a wanted criminal became void after five years. The family firm, Mengele Agrartechnik, struggled after the revelations: by 1991 it had 650 employees, half its size six years earlier, and was sold that year. By 2011 its brand had disappeared. The forensic conclusion was definitive, but its consequences extended beyond the grave: it established Mengele’s fate, documented the concealment around him, and made visible the limits of legal accountability for those who had helped him.
