Supreme Judicial Court of Maine
State of Maine v. David MacKenzie
August 19, 20252025 ME 79
Summary
The court affirmed MacKenzie's convictions for aggravated OUI, aggravated assault, and leaving the scene of a motor vehicle accident. It held that the OUI statutes do not make a chemical test the exclusive method of proving BAC and that the chemist's Widmark-formula estimate was sufficiently reliable for admission, although it could not be used to invoke the statutory presumption of intoxication. The court also held that the evidence was sufficient for the jury to find recklessness and causation supporting aggravated assault. The judgment was remanded solely for correction to reflect that certain sentences ran concurrently.
