Most people who buy DNA test want to know the truth but there are others who want to evade it. In 1992, Dr. John Schneebergerim planted 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 we need to be careful in DNA testing, doesn’t it?
