Exhumation and identification of Josef Mengele's remains

The exhumation and identification of Josef Mengele’s remains in Brazil in 1985 transformed an uncertain manhunt into a forensic conclusion. Investigators traced his family’s concealed connections to a grave in Embu das Artes, where the skeleton had been buried under the name Wolfgang Gerhard. Examination of physical features and comparison with photographs and records led specialists to identify the remains as Mengele’s; DNA tests confirmed their conclusion in 1992. The discovery settled the question of his identity, while exposing how people close to him had helped preserve his concealment.

From concealed correspondence to the grave

The investigation gathered force after Hans Sedlmeier, who had continued sending money to Mengele, disclosed that fact during a dinner in the Black Forest in autumn 1984. A listener reported it to the police. On 10 May 1985, a German prosecutor told American and Israeli partners that a search of Sedlmeier’s home was planned. This time, Günzburg police did not warn the person under investigation.

At the end of May, police searched Sedlmeier’s 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 Mengele’s death. Sedlmeier declined to cooperate and was placed under house arrest while investigators worked through the address book. Its information led them to Brazil.

São Paulo police then kept the Bossert and Stammer families under continuous surveillance for four days, but did not find Mengele. On 5 June, officers raided the Bosserts’ home at dawn. A dresser held keepsakes and recent photographs of the older, moustachioed man, evidence of the family’s connection to him. Bossert disclosed that Mengele was dead and buried in Embu cemetery, in a vault under the name Wolfgang Gerhard.

The account from Gitta Stammer was less direct. The following day, she recognized the man in a photograph as Peter Hochbichler, the Swiss man who had managed the family’s farms for a long time, and said that Gerhard had introduced them. She denied knowing anyone named Josef Mengele. Her husband, Geza Stammer, was not questioned because he was on a cruise in Asia. These different responses left investigators with a grave to examine, but also with continuing reasons to scrutinize the family’s account.

The exhumation and competing interpretations

News of the discovery reached the press before the identification was settled. On 6 June, reporters and photographers gathered around the police and the Bosserts as officials exhumed the contents of Gerhard’s grave in Embu das Artes. The coffin was brought up and opened, exposing the skeleton. The public scene made the discovery appear dramatic, but the central question remained evidentiary: whether the bones were actually those of Mengele.

Scepticism had a history. The Israelis and the Klarsfelds questioned why the family had kept silent for six years and why the information had emerged when it did. They suspected a further deception that might allow Mengele to remain free. Simon Wiesenthal also withheld belief. By then, reports had declared Mengele dead seven times, in places ranging from the Russian front and Paraguay to Brazil, Bolivia, and Portugal. The repeated false or unverified reports made announcement itself inadequate proof.

Forensic comparison and confirmation

Specialists assembled several kinds of identifying evidence rather than relying on the name attached to the grave. They determined the skeleton’s blood group, recovered hair from the head and moustache, took a fingerprint, and measured the bones and the gap between the upper front teeth. They also examined the vertebrae and femurs, a hole in the left cheekbone, and the prominent forehead. These observations were compared with photographs of Mengele as a young and an older man.

The investigators also consulted Mengele’s SS file, which recorded a pelvic fracture after a motorcycle accident at Auschwitz. That prior record offered a further point of comparison with the skeleton. The details did not all have the same identifying force in isolation; together, the physical examination, photographs, and recorded medical history formed the basis for the specialists’ assessment. On 21 June 1985, forensic pathologists at police headquarters in São Paulo announced that, to a reasonable degree of scientific certainty, the remains from Embu were Josef Mengele’s.

The conclusion was subsequently reinforced by genetic testing. In 1992, DNA tests confirmed the experts’ opinion. Germany, Israel, and the United States then definitively closed the case. The progression—from a grave under an assumed name, through an initially contested examination, to a forensic conclusion and genetic confirmation—gave the identification a strength that earlier reports of Mengele’s death had lacked.

Family disclosure and the aftermath

The investigation also prompted Rolf to break his silence. He considered selling his father’s letters and notebooks, along with photographs from his trip to Brazil, to Stern magazine, but instead decided to give them to Bunte. Proceeds from sales of the issue were to go to associations of concentration-camp survivors. Its 18 June cover showed Mengele in old age, wearing a high-collared shirt and straw hat; the accompanying report stated that his family had known where he was hiding and had supported him financially.

Rolf confirmed in a brief statement that his father had died in Brazil in 1979 and expressed sympathy to the victims and their loved ones. He said he had withheld the death out of consideration for those who had helped Mengele. He did not address his father’s atrocities. Dieter, Karl-Heinz, and Sedlmeier likewise maintained silence. The identification therefore resolved the question of the body without producing a full public account from the circle that had sheltered him.

Mengele’s remains were stored in a cupboard at São Paulo’s Legal Medical Institute, and his family did not claim them. He was left without a grave. The identification ended the official search, but its closing image was not a burial or a family acknowledgment: it was an unclaimed set of remains, made identifiable through evidence after years of concealment.
