Colorado DUI results challenged; former lab tech says signature forged to certify machines
BLACK HAWK, Colo. -- Thousands of DUI convictions statewide could be in jeopardy if defense attorneys convince Gilpin County Judge David Taylor to side with them. The issue is the Intoxilyzer 9000, the alcohol breath test used to help convict thousands of people every year. Mike Barnhill, a former technician for the state health lab that certifies the Intoxilyzer 9000, said his signature was forged many times to certify the machines for use.
