A 34-year-old Stratford woman was found dead inside the back seat of a parked car in Westport, police say.

The discovery was made Sunday in the parking lot of 40 Jesup Road just before 9 p.m.

Police say the woman was lying unresponsive in the back seat of the car with the engine still running.

First responders attempted to revive the woman at the scene, but she was transported to the hospital where she was pronounced dead.

Police say the investigation is in its early stages, but no foul play is suspected.

Officials have not released the woman's identity, but say the Connecticut Medical Examiner’s office in Farmington will determine the exact cause of death.
