Two vehicles were traveling northbound at a high rate of speed when one of them, a 2013 BMW 650I, changed lanes and struck a 2020 Mercedes E-Class, which was not involved in the speeding. The Mercedes hit the guardrail, while the BMW struck the jersey wall, ejecting its driver. The Mercedes then struck the driver of the BMW.
The driver of the BMW, Kenneth D. Buckner, 35, of Washington, D.C., died at the scene. Police confirmed he was not wearing a seatbelt. A passenger in the BMW, Tyra Williams, 29, was partially ejected and sustained serious injuries. She was transported to an area hospital for treatment.
