From Fairfax County police:
Fairfax County Police are investigating a fatal crash that took place on the Fairfax County Parkway in the early morning hours of June 1.
Preliminary investigation indicates that a 24-year-old man drove from the southbound into the northbound lanes near Wiehle Avenue around 1:45 a.m. and struck a taxi cab head on. Both passengers in the taxi, men ages 29 and 34, died on scene. The suspect driver and taxi cab driver (47-year-old man) were transported to the hospital and are in serious condition.
Detectives are investigating whether speed and alcohol may be factors involving the at-fault driver of the crash and two counts of aggravated involuntary manslaughter charges are pending. Identifications are being withheld pending notification to next of kin.
The southbound lanes of the Fairfax County Parkway have been re-opened; however the northbound may be closed for the ongoing investigation.
