WEST GARDINER — The identity of the person who died Saturday in a single-vehicle crash on Interstate 95 had not been determined as of Sunday, according to police.

Shannon Moss, public information officer for the Maine Department of Public Safety, wrote Sunday in a statement released to the news media the Office of the Chief Medical Examiner is expected to perform an autopsy to determine the identity of the driver of the vehicle that crashed at the southbound toll plaza in West Gardiner.

The investigation by the Maine State Police indicates the vehicle, either a minivan or a sport utility vehicle, was southbound when it crashed into a guardrail, redirected back onto the highway and then struck the center pylon at the toll plaza, causing the vehicle to burst into flames.

The vehicle’s single occupant was declared dead at the scene.

The lane in which the crash occurred was closed for about two hours while the vehicle was removed. The high-speed lanes remained open.
