Two women died and two other people were injured in a crash on a Northern Virginia highway.
Fairfax County Police responded about 2 a.m. Sunday to the crash site off Fairfax County Parkway in Reston.
They believe the driver of a 2004 Acura MDX lost control and left the roadway. Preliminarily, they believe speed and alcohol may have been factors in the crash.
At least one other vehicle was present during the crash and remained when officers arrived, police said.
Twenty-one-year-old Tonnisha McCoy of Sterling and 23-year-old Joselyn Herndon of Reston were pronounced dead at the scene. Two others were injured.
Police said Sunday they were still trying to piece together exactly what happened. Alcohol and excess speed have not been ruled out as factors.
Joselyn Herndon's family is raising money for her funeral and her 2-year-old daughter via a GoFundMe page.
