Mengele’s Arrest and Release in the 1958 Illegal Abortion Case

Josef Mengele’s 1958 arrest in Argentina was a rare interruption in his fugitive life: police took him into custody after an investigation into clandestine abortions identified him as a doctor operating under the name Gregor. He was released after three days through a corrupt arrangement, not through any resolution of the charges. The episode exposed his vulnerability to ordinary policing even as the failure to hold him showed how readily money and compromised officials could turn arrest into another temporary setback.

The investigation reaches Gregor

The immediate case followed the death of a girl younger than fifteen after an abortion. The investigation broadened when a doctor in custody denounced colleagues, enabling police to dismantle a network of clandestine procedures. In the ensuing public scandal, newspapers reported on the doctors under investigation. Police identified Gregor as Josef Mengele, connecting a local criminal inquiry to a fugitive already sought for his role in the selections at Auschwitz.

A police summons had been waiting among Mengele’s mail, but he had failed to report to the Olivos police station three days earlier. When he and Martha returned home, a neighbour warned that officers had come on the previous two days and were now at the door. Two sergeants handcuffed Mengele and took him away. The sequence left little space for preparation: the summons had gone unanswered, the police had returned repeatedly, and the arrest came as he was arriving home.

Custody and a corrupt bargain

In custody, Mengele denied the accusations at first. Confronted with the case, he acknowledged having performed a small number of operations in the past, said he would not resume them, and tried to negotiate with the officer. The book presents this as a transaction rather than a meaningful acceptance of responsibility: the officer detained him, then summoned him again on the third day to ask how much he would pay.

Mengele increased his initial offer, doubling and then tripling it. He was released after the payment was accepted. The officer kept the case file in his personal archives, a detail that makes the outcome more than a simple failure of evidence or procedure. The investigation had reached Mengele, but an official with control over the file converted that exposure into a purchasable reprieve. After returning home, exhausted and distressed, Mengele was embraced by Martha, who was herself deeply agitated.

A second line of pursuit

The release did not end the danger. Martha showed Mengele a telegram from Hans Sedlmeier reporting that, in early August, a journalist had lodged a formal complaint against him in Ulm. The complaint followed public attention to the disappearance of former SS personnel and to the unresolved question of what had become of the Auschwitz doctor. An anonymous letter sent to a newspaper had alleged that Mengele lived in South America; the editor passed it to Ernst Schnabel, who forwarded it to the attorney general in Ulm. Thus, while the Argentine case concerned illegal medical practice, a separate line of inquiry was connecting the fugitive’s assumed identity and location to his Nazi past.

That investigation encountered institutional reluctance. Hermann Langbein, a former prisoner of Dachau and Auschwitz and a co-founder of the International Auschwitz Committee, had been collecting evidence and believed Mengele was in Buenos Aires. The German federal justice minister said the case belonged before a regional court. Although most judges refused to act, a prosecutor in Freiburg im Breisgau issued an arrest warrant on 25 February 1959, citing multiple cases of premeditated murder and attempted murder. Langbein then pressed for the West German government to seek Mengele’s extradition from Argentina.

From release to renewed flight

Mengele’s brief release in 1958 did not itself produce the later arrest warrant, but the episode sits at a turning point: he had been identified by Argentine police while investigators in West Germany were separately building a case against him. When a police informant passed on news of the warrant, Hans Sedlmeier urged him to leave. Mengele sold his villa and shares, closed his bank accounts, and went into hiding in Paraguay. His wife and son could remain in Argentina, but they were to move and keep a low profile.

Extradition efforts then met a maze of jurisdictions and delays. Requests moved through Argentine ministries, courts, and police, while West German officials proceeded without urgency. In Paraguay, Hans-Ulrich Rudel intervened on Mengele’s behalf, and the authorities granted him citizenship in November 1959 despite his failure to meet the stated five-year residency requirement. That status helped shield him from extradition. The subsequent history therefore sharpened the contrast already visible in the 1958 arrest: police could seize him, and prosecutors could issue a warrant, yet neither action guaranteed that the institutions and governments holding the relevant powers would deliver him to trial.

Significance and aftermath

The case was not a prosecution for crimes committed at Auschwitz, and Mengele’s release did not clear him of the separate accusations pursued by West German authorities. Its significance lies instead in the chance exposure of a man who had been living under an assumed name and in the means by which he escaped immediate consequences. A local criminal investigation found him; a corrupt officer kept the file and accepted payment; a separate legal process advanced across borders but faced delays and resistance.

The later international hunt made that failure more visible. After Adolf Eichmann’s capture in Buenos Aires, journalists and investigators turned their attention to Nazi fugitives in South America, and West Germany issued another warrant for Mengele on 20 June 1960. Years later, testimony by Auschwitz survivors at the 1985 mock trial in Jerusalem renewed demands for his capture, and the United States, Israel, and West Germany coordinated efforts to find him. The 1958 arrest had shown that Mengele could be located and detained. His escape from lasting custody showed the distance between finding a fugitive and bringing him to justice.
