A calibration error at the Orange County Crime Lab was being blamed Thursday for mistakenly identifying drivers as having blood-alcohol levels above the legal limit, authorities said
A flawed test was in use for nearly five months and has so far been linked to false results for about 20 people, according to a O.C. Crime Lab Director Bruce Houlihan.
Houlihan told KTLA that a calibration error threw off the result by .003 percentage points.
The district attorney’s office is trying to determine whether any of the affected cases have gone to trial or resulted in a court plea.
Letters were sent out to another 900 people notifying them of possible inaccurate results.
