To Whom It May Concern:

The Michigan State Police (MSP) has advised my office of performance-related issues by an outside vendor regarding specific Datamaster Breath Testing Instruments used in the State of Michigan. Please see the enclosed letters from the Michigan State Police for details about these issues. The Michigan State Police has assumed the duties previously contracted by the aforementioned vendor.

Per the Michigan State Police's January 16th, 2020 letter, MSP has identified six cases in Wayne County affected by the aforementioned issues. Only one of those six identified cases in Wayne County was prosecuted by the Wayne County Prosecutor's Office. The remaining five identified cases are local matters not handled by the Wayne County Prosecutor's Office.The Wayne County Prosecutor's Office will continue to contact attorneys on a case by case basis regarding any case being prosecuted by the Wayne County Prosecutor's Office that the Michigan State Police notifies us is affected by the issues detailed in the enclosed letters.

Per the January 10th, 2020 letter from the Michigan State Police, "Fully certified MSP personnel will ensure that all Datamaster DMTs are certified, calibrated, and serviced according to state law and industry standard."

We will work cooperatively with you to resolve any issues that arise from the information received from the Michigan State Police. If you have any questions or concerns, please contact APA David McCreedy of our Appellate Division at 313-224-3836.
