Impossible Things Before Breakfast, 2


by Leigh Lundin

Last week, I wrote about a 1997 case of where a victim appeared to have committed a murder after she was killed. Impossible, it seemed, and so it was.

This week, we move to a crime wave that plagued parts of western Europe for a decade and a half. In 2009, authorities offered an reward of €300 000 ($415 000) to bring the perpetrator– a woman– to justice.

German police, and later French and Austrian investigators, captured the DNA of a woman with few clues to her identity other than she came from a Slavic bloodline. Female serial killers are not yet as common as male killers, but this one was criminally prolific, engaging in burglary, robbery, car theft, home invasion, drug dealing, and murder– including the slaying of a police woman, which ramped up the manhunt, or woman-hunt, if you will. European news media began to call her the Heilbronner Phantom– the Woman Without a Face.

Silver Blaze

Profilers from across Europe were asked to imagine the suspect. Heilbronn police estimate 16 000 hours of overtime went into tracking the elusive woman. Concern heightened again when German investigators found the same DNA in a car used to transport three corpses, followed by the execution of a policewoman, Michèle Kiesewetter, and the nearly fatal attack upon her partner.

One clue was like the Sherlock Holmes’ dog in the night-time: Although DNA cropped up in crime scenes surrounding the German state of Bavaria, none was discovered in Bavaria itself, a sign of omission. Whether that raised eyebrows of detectives isn’t known, but two subsequent crimes cast doubt on the Phantom’s identity.

The first flag came from a fire when officers sampled a male corpse… and turned up female DNA, that of their long-running suspect. Eye-witnesses had occasionally reported seeing a man at crime scenes– not a woman– but eye-witnesses are notoriously prone to errors of identification. Investigators resampled the deceased using different cotton swabs and came up with a different result– no female DNA.

The final nail in the theory followed a shootout with a neo-Nazi terror cadre that killed two men. At the death scene, detectives found police handcuffs belonging to Michèle Kiesewetter. The Phantom DNA did not match the only woman in the terrorist cell, Beate Zschäpe, which raised doubts that the attack on police woman and her partner was committed by the Phantom of Heilbronn.

DNA
System Reset

While German tabloids like Bild ridiculed police by asking if their heads were stuffed with cotton wool, investigators quietly reexamined their methodology and the source of their instruments and test materials. They identified the real culprit– the departments’ miserly buyer of cotton swabs.

As Dr Mike Silverman discovered in last week's article, sterile doesn’t mean DNA-free. Sterilization might kill viruses and bacteria, but it doesn’t necessarily eradicate DNA strands. Police departments throughout Germany– except Bavaria– were buying inexpensive cotton buds from an Austrian company, Greiner. The company certified their Bio-One swabs sterile but not suitable for human DNA collection.

The mysterious ‘Phantom’ was none other than one of Greiner's assembly line employees. She'd accidentally contaminated countless cotton buds with her own DNA.
