Two men are dead after a police chase that started on the Beltway ended in a fiery crash in Prince William County early Sunday, the Virginia State Police said.

The incident began around 3:45 a.m. after a state police trooper attempted to stop a Dodge Charger speeding on the westbound Beltway near Eisenhower Avenue in Alexandria, state police said.

The driver of the Dodge refused to stop and then got off the Beltway and headed south on Interstate 95, before speeding onto the exit ramp for Route 123 in Prince William County, the state police said.

The driver lost control of the Charger on the ramp, ran off the road, struck a jersey wall, and then rode up a cement wall and struck the bottom of the underpass for the I-95 express lanes, state police said. The car then caught fire.

Troopers managed to remove the driver and passenger before the Charger was fully engulfed in flames, the state police said. Both men were pronounced dead at the scene of the crash. The driver was identified as Curtis Armstead Jr., 24, and the passenger as Miquel D. Jenkins, 23 — both of Fredericksburg, Va.

A bag containing a white powdery substance was found with the men, the state police said. The investigation into the crash is ongoing.
