The Minnesota Bureau of Criminal Apprehension (BCA) has confirmed that its DWI breathalyzer tests remain accurate after a review was conducted due to discovered data entry errors. The errors, related to dry gas cylinders used in the devices, initially raised concerns that up to 276 cases could be compromised.

After recalculating the test results, the BCA determined that the alcohol concentration values were accurate and within established margins. Amended reports will be issued to law enforcement agencies, and more than half of the instruments have already been verified and secured, with full completion expected in the coming weeks.

So here's what we know. The B. C. A. Said in September, discovered in some cases incorrect information had been entered into breathalyzer tests, resulting in test data being potentially compromised. At the time, officials say up to 276 cases could have been impacted. The error was related to dry gas cylinders installed on the devices.

So what did this mean for the nearly 300 cases? Here's what the superintendent had to say. But with these calculations, we will be issuing amended reports outlining what the impact of that was in the calculation that we went through this mathematical equation to determine the accuracy of those results. So that will get issued to each of the law enforcement agencies that will be amended the file and then the prosecutors and defense attorneys will be able to examine what the impact of any and there shouldn't be to the case that's at hand.
