It was obvious that this was an artifact. I mentioned this long time before the case was "solved". https://www.metafilter.com/73462/Onewoman-crime-spree
What is the biggest achievement of the Bavarian police? Being so incompetent in the 72 olympics so that the GSG9 special forces were created.
Specifically, Bavaria had no reports of crimes committed by the Phantom.
https://en.wikipedia.org/wiki/Phantom_of_Heilbronn
"It was found that the contaminated swabs all came from the same factory, which employs several Eastern European women who fit the type the DNA was assumed to match. Bavaria, although a region central to the crimes, obtained their swabs from a different factory. They had no reports of crimes committed by the Phantom."
The cause for all DNA detections was: the use of sterile but not DNA-free cotton swabs:
"the laboratory results were due to contamination of the cotton buds used for DNA probing. Although sterile, the swabs are not certified for human DNA collection."
The Wikipedia article lists the locations of the crimes, obviously these swabs were more widely used, and they even weren't used in Bavaria.
Still irrelevant to the article, however.
Bavaria has the lowest crime rate of all German states and proportion of crimes solved in the state is the highest in Germany.
It is apparent that you do not. The Bavarian police has an excellent track record.
