According to 9News, as many as 33 DUI cases could be reopened in Weld County due to a technician’s faulty calibration of one of the county’s new Intoxilyzer 9000 machines.
An unnamed employee with CDPHE has been disciplined, but details have not been released.
The 33 faulty tests allegedly occurred between August 2013 and January 2014, all in Weld County DUI cases. The study reviewed approximately 12,000 tests, statewide.
Dr. Larry Wolk, executive director of the CDPHE, stated that the problem was “human error” rather than any intrinsic flaw with the machine and that his office has changed some of its protocols to avoid similar problems in the future.
Colorado purchased 165 of the new breathalyzers in 2013 and was the first state to adopt the model in question.
