Investigators say 69-year-old Sai Leung Li of South Riding in Loudoun County was driving Westbound on Lee Jackson Memorial Highway when he went off the roadway and crossed Centreville Road.
They say a medical emergency may have prompted Li to enter Centreville Road, where he crashed into five cars that were stopped in the southbound lanes.
Li was taken to a local hospital, where he died.
One passenger in another vehicle was also taken to a local hospital. Police do not believe that person’s injuries are life threatening.
Investigators do not believe speed or alcohol were factors in the crash.
