Police were dispatched shortly before 6:30 a.m. Thursday to a report of a vehicle underneath a truck with two people heavily trapped on the southbound side of the ramp into the Walt Whitman Service Area.
State Police tell Action News that a private Town Car travelling from New York hit an illegally parked tractor-trailer on the rest stop exit ramp.
The female passenger in the back seat of the Town Car was extricated from the car and flown to the hospital by medical helicopter. She was later pronounced dead.
The driver of the Town Car, a friend of the woman who was killed, was injured but is expected to survive.
There is no word at this time if anyone will face charges. Police are continuing to investigate.
