[crime] The strange case of the ‘time travel’ murder … a look at the fallibility of DNA in crime investigations … ‘In Germany in 2007, traces of DNA belonging to an unknown female were found at the scene of the murder of a police officer. When run through the German database, identical DNA was found to have been present at the scene of five other murders in Germany and France, along with several burglaries and car thefts. In total, the woman’s DNA was found at 40 separate crime scenes. The German authorities spent two years and thousands of hours searching for the culprit, only to discover that the DNA had in fact been present on the swabs the crime scene investigators had been using to collect their samples. The swabs had been accidentally contaminated by a woman working at the factory that produced them.’
