Scientists in Israel have demonstrated that it is possible to fabricate DNA evidence, undermining the credibility of what has been considered the gold standard of proof in criminal cases. The scientists fabricated blood and saliva samples containing DNA from a person other than the donor of the blood and saliva. They also showed that if they had access to a DNA profile in a database, they could construct a sample of DNA to match that profile without obtaining any tissue from that person. You can just engineer a crime scene, said Dan Frumkin, lead author of the paper, which has been published online by the journal Forensic Science International: Genetics. Any biology undergraduate could perform this. Dr. Frumkin is a founder of Nucleix, a company based in Tel Aviv that has developed a test to distinguish real DNA samples from fake ones that it hopes to sell to forensics laboratories. The planting of fabricated DNA evidence at a crime scene is only one implication of the findings. A potential invasion of personal privacy is another. Using some of the same techniques, it may be possible to scavenge anyones DNA from a discarded drinking cup or cigarette butt and turn it into a saliva sample that could be submitted to a genetic testing company that measures ancestry or the risk of getting various diseases. Tania Simoncelli, science adviser to the American Civil Liberties Union, said the findings were worrisome. DNA is a lot easier to plant at a crime scene than fingerprints, she said. Were creating a criminal justice system that is increasingly relying on this technology.
