A Malicious Fairy Princess Spreading Spreading Pixie Dust Laced with DNA over European Crime Scenes?

A friend alerted me to the following odd story about the "phantom of Heilbronn." See Tristana Moore, "Germany hunts phantom killer," BBC News (April 21, 2008). European police have recovered "matching" DNA -- DNA said to belong to a single unknown female person -- from crime scenes in a wide variety of areas in Europe involving a variety of crimes (30 sets of crimes) committed over a period of 15 years. The police now think they may be close to identifying the perpetrator -- either that or the source of this DNA. It will be very interesting to see how this story unfolds.
