How to Fake a DNA Test
by Dr. Hsien-Hsien Lei
Posted April 13, 2008 in DNA and the Law
Most people who buy DNA test want to know the truth but there are others who want to evade it.
In 1992, Dr. John Schneeberger implanted a plastic tube in his arm filled with someone else’s blood. He had been charged with two counts of sexual assault in Saskatchewan, Canada. When ordered to provide a blood sample, Schneeberger drew the blood himself from the plastic tube instead of his vein. He was eventually deported and sent back to South Africa.
In March 2007, four Massachusetts men were charged with attempting to tamper with DNA testing. They apparently tried to trade ID bracelets when having their blood drawn but was caught when their fingerprints didn’t match the samples. I’m not sure what became of them but they faced a sentence of up to five years in jail.
And in a paper published in the Journal of Forensic Sciences, Dr. Jose Antonio Lorente Acosta at the Laboratory of Genetic Identification of the University of Granada found evidence of fraud in a paternity test case. The suspect had applied another person’s saliva to the inside of his mouth prior to having DNA samples taken with a cotton swab.
And what about accurate DNA analyses that are reported INaccurately? I’m sure there are unscrupulous DNA testing services worldwide that will give people any results they want for whatever purposes they need it for, e.g., immigration. Not to mention people like Simon Mullane, a British businessman who made-up paternity test results rather than actually doing the testing. Makes you think twice about the accuracy and validity of DNA testing, doesn’t it?

What about Brian Meehan of DNA Security studying the DNA in the Duke Lacrosse team “rape” case, finding 5 separate individuals’ DNA in the panties but none matching any of the Duke Lacrosse players and not disclosing their findings. That fact eventually broke the case, destroyed the DNA Security company, and disbarred the District Attorney.
Great example, Guy. Human error, deliberate or accidental, plays a role even when it’s something that should be definitive like DNA tests.
I realized the Meehan example is not like a person falsifying his own DNA. My point is not to have 100% certainty in DNA results reported by humans, because human error deliberate or accidental can give false information.
Absolutely, Guy. Totally agree with you. Thanks for the comments!
Hsien,
Sounds more and more like Gattaca every day.

Steve, Only without the beautiful people….
Security specialist Bruce Schneier recently wrote about the stolen fingerprints of a German Minister, where he referred back to a Biometrics article from 10 years ago:
http://www.schneier.com/crypto-gram-9808.html#biometrics
The last paragraph is a perfect summary. Basically, biometrics are not secrets, and are only useful when there is a trusted path from reader to the verifier.
In all except the Granada saliva case, there is a clear breakdown of the trust path between the reader and the verifier.
Clinton, I used to think that chain-of-custody DNA testing was as good as it can get but clearly, humans can be duped at any step along the way. Thanks for the link. I remember reading about the stolen fingerprints. Nuts.
Hsien,
Beauty is in the eye of the beholder.
