Josef Mengele, the "Angel of Death" at Auschwitz concentration camp, spent his last years in his Brazilian hideaway lonely, depressed and short of money, according to 86 letters, notes and diaries discovered filed away in a Sao Paulo police archive.
One of the most wanted Nazi war criminals, because of the experiments he conducted on children and other inmates, Mengele apparently lived his last years suffering intense abdominal pains.
Fear of being discovered made him chew the ends of his moustache, resulting in a ball of hair blocking his intestines.
The typewritten letters and handwritten notes were found when police files were being reorganised, and excerpts were translated and published by the newspaper Folha de S Paulo.
