The passenger killed early Thursday in a crash on Interstate 395 has been identified as 25-year-old A. Tawab Ebadi of Chantilly.
Edabi was in the back seat of an Audi A8 being driven by Javed Hussaini, 25, of Manassas, when it ran off the road, spun around and hit a tree, according to the Virginia State Police.
The car hit the tree with enough force to split the vehicle in half, sending part over the guardrail, police said.
Hussaini has been charged with manslaughter while driving under the influence.
The crash happened when the vehicle was taking the ramp from southbound I-395 to westbound Little River Turnpike/Route 236. Police were called to the scene at 2:41 a.m.
Edabi and another passenger in the back seat were thrown from the car. Edabi died at the scene, while Hussaini and the two other passengers were taken to a nearby hospital and are being treated for non-life-threatening injuries.
Alcohol and speed were both factors in the crash, which remains under investigation, police said.
