A New York man accused of driving drunk and causing a crash that killed a Seekonk teenager and his grandparents in 2023 was back in court on Monday.

Adam Gauthier, 41, formerly of Somerset, pleaded guilty to three counts of manslaughter while operating under the influence and two counts of assault and battery.

He was sentenced to serve 12 to 15 years in prison, followed by two years of supervised probation.

On Christmas night in 2023, investigators said Gauthier was driving drunk on the wrong side of the Veterans Memorial Bridge when he crashed into an oncoming car.
