"DUI results from across Tennessee may be in jeopardy after the firing aTennessee Bureau of Investigation employee for mishandling evidence.

The Chattanooga Times Free Press reported (http://bit.ly/1aT6bIv) that former Special Agent Kyle Bayer handed 2,800 cases before being dismissed Monday after an internal review revealed he mistakenly switched two blood alcohol samples in a vehicular homicide case in Hamilton County."

If you gave a blood test, the lab saves a sample for 30 days. You must act right away to tell them to save the sample so that you can get it independently tested. Don't just rely on the State's crime lab to tell you what your blood alcohol concentration was.
