Overview
- The Bureau of Criminal Apprehension ordered agencies to pause DataMaster use until a quick verification confirms correct cylinder data entry, allowing devices back in service after a five-minute check.
- Officials cite wrong or improperly installed dry gas bottles as the cause, with five counties identified so far: Aitkin, Chippewa, Hennepin, Olmsted and Winona.
- The tally of potentially affected tests stands at about 276 to 277 out of roughly 15,000 conducted this year, and the figure remains subject to change as inspections continue.
- County attorneys are reviewing cases tied to suspect results, and some jurisdictions have begun dismissals, including reports out of Winona County.
- The BCA plans to centralize cylinder changes and calibration to curb user error, while DWI enforcement continued using preliminary breath tests and other tools during the review.
