For many years, German police have been searching for a seemingly very busy female serial killer. Traces of her DNA have been found in up to 40 crime scenes, dating back to 1993. Finally, the mysterious female has been located, with help from Austrian police.
They found the woman working at her job in a factory packing cotton swabs used to take DNA samples.
Seems that the cotton swabs are sterile and suitable for many medicinal purposes, but were never guaranteed to be totally DNA-free. The procedure to ensure that a swab has absolutely no traces of any DNA makes the product significantly more expensive. Various police forces thought they could go with the cheaper ones simply because they were sterile. Now they've found out that what seemed to be a great deal has ended up wasting thousands of hours in searching for a prolific killer who never existed.
ONE WONDERS HOW MANY PEOPLE ARE BANGED UP AS A RESULT OF DODGY FORENSIC EVIDENCE.

In fairness, probably about none, although you do hear of the odd case where the few pieces of evidence were only circumstantial, it's usually the DNA that clears them...
