Linked – DNA blunder creates phantom serial killer
I’ve heard it said often that shows like CSI have created this expectation by jurors that they see the DNA evidence, or that there is simple magic in DNA evidence, or poor security camera footage. Turns out, that expectation that the DNA always tells the story, might need to be looked at again:
“The only clues that “The Woman Without a Face” left behind at 40 different crime scenes were DNA traces. These were collected on cotton swabs, supplied to the police in a number of European countries. Now police investigators have established that in all probability the DNA had not been left by their quarry but by a woman working for the German medical company supplying the swabs, who had inadvertently contaminated them.”
