State troopers responded to a motor vehicle that had gone off the road near Reed Plantation on Saturday night.
Police say that a man and woman were trapped under the vehicle after it overturned.
The two were traveling north and failed to negotiate a right hand curve in the road.
Police say the vehicle went into the guardrails and became airborne. The vehicle rolled multiple times and hit a guide wire pole before coming to rest down over an embankment.
According to police, 46 year old Gail Suitter was rescued and transported to Houlton Regional Hospital with serious injuries.
47 year old Richie Suitter died at the scene from his injuries.
The investigation is ongoing but speed and alcohol are believed to be the cause of the crash.
