Man Sentenced to 9 Months in Jail for Falsifying DataMaster DMT Service Records

One of the men charged with falsifying documents related to tests and repairs on DataMaster Transportables, a breathalyzer that measures driver’s breath alcohol concentration, will spend nine months behind bars.

In 2020, Attorney General Dana Nessel filed charges against Andrew Clark and David John, who worked as technicians, for creating fake documents to show that they completed certain diagnostic tests and repairs on two DataMaster instruments for calibration and performance.

Clark was sentenced Thursday to serve 36 months probation with the first nine months served in the Eaton County Jail. He had been convicted last month to two counts of forgery of a public record, a 14-year felony charge, two counts of uttering and publishing, a 14-year felony charge and two counts of using a computer to commit a crime, a 10-year felony.

“Our public integrity team continues to demonstrate the great importance of pursuing bad actors who subvert the criminal justice system and threaten the integrity of our judicial process,” Nessel said. “We must show that those who undermine the public trust risk jail time in doing so.”

John had pleaded guilty to all nine charges he faced and was sentenced to 36 months probation, with the first nine months served in Kalamazoo County Jail.
