In 2002, the Institute for Forensic Medicine of the University of Münster analyzed hair and body cells from locks of hair and items of clothing that also belonged to Kaspar Hauser. The analysts took from the items used in the test six different DNA samples, all of which turned out to be identical. All, however, differed substantially from the blood sample examined in 1996, the authenticity of which was therefore questioned. The new DNA samples were compared to a DNA segment from Astrid von Medinger, a descendant in the female line of Stéphanie de Beauharnais. The sequences were not identical, but the deviation observed is not large enough to exclude a relationship as the difference could be caused by a mutation. (The mitochondrial DNA which was examined is passed only through the female line and thus cannot change except through mutation.) On the other hand, the relatively high similarity by no means proves the alleged relationship, as the "Hauser samples" showed a pattern amongst the German population.
