@Stosh21: I am flairing this debunked. Mengele's remains were exumed and DNA tested in 1985. His son admitted they were his. Here's the article, from PubMed:

Discovery, development, and current applications of DNA identity testing

Newer methods and the “Angel of Death”

By the end of 1986, DNA profiling was being used all over the world. DNA typing was refined with the introduction of the polymerase chain reaction (PCR) together with the discovery of different repeating sequences called microsatellites. DNA amplification by PCR provides increased sensitivity, thus allowing small amounts of DNA to be analyzed, even from archival and partially degraded samples.

Minisatellites, also known as variable numbers of tandem repeats (VNTR), are made up of repeated sequences that can vary in unit length from 6 to 100 bases. These units can be repeated two to several hundred times at each minisatellite. Thousands of different minisatellites are scattered throughout the genome, but they are often clustered near the telomere, or end of the chromosome (9–11).

Microsatellites, also known as short tandem repeats (STR), are made up of a unit that can vary in length from 1 to 7 bases. This unit is repeated 5 to 100 times at each microsatellite locus. Thousands of different microsatellites are randomly scattered throughout the genome, but not in a specific area (12, 13).

PCR-based DNA typing was used to end the 40-year hunt for Nazi prison camp doctor Josef Mengele, who escaped from the Allies at the end of World War II. Nicknamed the “Angel of Death” at Auschwitz, Mengele was thought to have fled to South America. Police were eventually given a tip that Mengele had drowned at sea in 1979 and was buried in Brazil. In 1985, the badly decomposed remains were exhumed so that DNA samples could be taken, but the specimens were so poor that Professor Jeffreys resorted to what amounted to reverse paternity testing: he used blood specimens from Mengele's wife and son to reconstitute Mengele's DNA pattern. In 1992, the remains were confirmed to be those of Mengele (14).
