Tri-County Regional Forensic's bad math means 11 bogus DWIs

​The screw-ups at the Tri-County Regional Forensic Laboratory who inflated the blood-alcohol content in urine samples over the last year got nearly a dozen innocent people charged with drunk driving.

The cause of the error wasn't some malfunction in sophisticated equipment or contaminated lab apparatus, either. According to a review by the Bureau of Criminal Apprehension, the lab wasn't performing the basic math calculations necessary to get the correct results. Since the lab never multiplied it's alcohol concentrations by 0.67, every result it reported since January was a third higher than the actual concentration.
