Two teens were killed, one injured, after their Porsche went off an overpass onto train tracks in Pearl River, New York, police said Monday.

Aisha Radoncic, 17, was behind the wheel of a 2017 Porsche Macan, but lost control and collided with a 2013 Volkswagen Jetta. This sent Radoncic and her passengers, Saniha Cekic, 15, and Altin Nezaj, 17, off the overpass onto the train tracks. The car burst into flames.

The driver of the Volkswagen, Jason Castro of Nanuet, was not injured in this collision. However, Nezaj died after the collision and Cekic died while being airlifted to a hospital nearby. Radoncic was severely injured and transported to a hospital for treatment.

Police still do not know what caused the crash, how it unfolded, and the condition of the injured teen.
