Metro Corrections chief launches investigation into certification lapses - Louisville Courier-Journal

Metro Corrections Chief Mark Bolton said Thursday that he has ordered an internal investigation to find out why four Breathalyzer technicians’ certifications had lapsed, jeopardizing the alcohol breath test results in about 600 local drunken-driving cases.
A preliminary investigation shows the technicians mistakenly believed they had been properly certified, Bolton said.
The Metro Department of Corrections said this month that the technicians mistakenly allowed their certifications to lapse in September and a system allowing employees to track their own certification would be replaced.
