A Brazilian pathologist is now using the bones of infamous Nazi doctor Josef Mengele, known by the Auschwitz inmates he tortured as the “Angel of Death,” to teach medical students at the University of São Paulo how to match forensic with historical data, the Associated Press reported on Wednesday.

According to the report, Daniel Romero Muñoz was among the researchers who identified the remains of Mengele, when his body was exhumed in 1985. Mengele, who fled to Brazil after World War II, died in 1979.

But the final identification came with a 1992 DNA analysis, which — the report said — followed a joint operation of the US, West Germany and Israel to track down the sadist who eluded capture for decades.

Nevertheless, the skeleton remained for more than 30 years at São Paulo’s Legal Medical Institute, since Mengele’s family refused to have it moved.

Today, students are examining his remains, and — Muñoz said — observing all kinds of health issues and injuries he had, such as a fractured left pelvis from a motorcycle accident in Auschwitz; a small hole in its left cheekbone, due to sinusitis; and dental abscesses, which he treated by himself, while in hiding, with a razor blade.

Mengele was infamous for conducting cruel experiments on Jews, whom he considered sub-human. In particular, he was known for his horrific torturous experiments on twins. Among his gruesome practices were extracting teeth, scalping, skin removal, injections of dyes and chemicals into eyes and starving babies to death.
