TRENTON, N.J. — New Jersey authorities say a state police sergeant faces charges for allegedly skipping a required step in the calibration of alcohol breath-testing devices.

But they say the issue doesn’t undermine the scientific credibility of any state police test results.

Marc Dennis was a coordinator in the state police’s alcohol/drug testing unit. He’s accused of deliberately omitting a step in re-calibrating three Alcotest devices, which were used to test the intoxication level of accused drunken drivers.

Dennis faces counts of tampering with public records and falsifying or tampering with records. His lawyer says Dennis denies the charges and plans to plead not guilty.

State authorities have identified 20,667 cases involving devices Dennis handled. They say the step he’s accused of skipping isn’t scientifically necessary but is required under a procedure developed by the state police’s chief forensic scientist.
