Overview

• The BCA directed agencies to stop using DMT devices until each unit’s dry gas cylinder data is verified as correct.
• Officials report at least 277 potentially affected DWI cases across five counties, including 108 in Olmsted, 73 in Aitkin, 45 in Winona, 38 in Hennepin, and 13 in Chippewa.
• Errors involve incorrect or mismarked dry gas cylinder identifiers used as control data, calling certain breath-test results into question.
• Prosecutors are reviewing cases, with at least one dismissal in Aitkin County and plans in Winona County to drop charges tied to compromised tests, and one license revocation has been rescinded.
• Hennepin County Sheriff’s Office says its machines are not faulty and reports double- and triple-checks as BCA-led inspections proceed.
