Roughly 20,000 drunk driving cases could be in question due to potentially faulty breathalyzer tests.

Attorney General Matt Parkin's office has made public the records of thousands of DUIs from 2008 to 2016 because they may have been tainted by officers using devices that weren't calibrated correctly.

Former State Police Sergeant Mark Dennis was in charge of overseeing the equipment and was sentenced in 2023 to 5 years in prison in part for failing to maintain their accuracy, making the test results inadmissible in court.

People who were charged with drunk driving during that time will have the chance to challenge their arrest and conviction.

More detailed information can be found on the state attorney general's website.

Anyone who believes their case should be reexamined is being advised to contact their attorney or public defender, along with the municipal court administrator, where their case was heard.
