The fatal single-vehicle accident was reported around 12:30 a.m. Friday, Nov. 22, at the intersection of Loudoun County Parkway and Tall Cedars Parkway.
Investigators say a 2023 Ford Mustang was traveling east when it veered off the roadway, struck a tree, and overturned.
Two male passengers died at the scene, the driver, a man, and another female passenger were taken to a nearby hospital for treatment of undisclosed injuries.
All individuals involved were adults, authorities said.
Later on Friday, investigators announced that 30-year-old Aldie resident Bijay Tamang, the river, was charged with involuntary manslaughter and held at the Loudoun County Adult Detention Center.
Alcohol is believed to be a factor and additional criminal charges are pending.
Tall Cedars Parkway was temporarily closed in both directions as authorities continue to investigate the crash.
More information is expected to be released.
