The ghost of Heilbronn or the case of "the woman without a face"
Between 1993 and 2009 the police in Middle Europe remained on alert trying to track down and stop a dangerous criminal and serial killer .Although the cases of female serial killers are very scarce, in this the woman was not at all at all: robberies, brutal murders...and also supported by complices of all nationalities.There was no clear pattern for her criminal adventures nor was her image registered in the crime videos.The investigators were baffled for years chasing a ghost first known as "the faceless woman." Among all these criminal acts, which they occurred basically in Germany, Austria and France a, only there was a common link: a woman's DNA.
From the analysis of mitochondrial DNA of the Austrian samples it was determined that this genetic type was more common in people of Eastern Europe.In 2007, Heilbronn police officer Michele Kiesewetter was murdered and the faceless woman's DNA reappeared.Since then it was known as "the ghost of Heilbronn" .300,000 euros reward for a clue that will lead to the arrest of the murderer.

The police resolved the case: the swabs with which the samples are taken were contaminated at source . The mysterious criminal did not exist.
The swabs used were sterile and therefore free of bacteria, fungi or viruses, but not of DNA resulting from involuntary contamination.It could be shown that they all came from the same German factory that He had among his employees many women from Eastern Europe.This fact represented the loss of thousands of hours of work and that many real criminals would be free since another profile was being pursued.
