FAIRFAX COUNTY—A 73-year-old Franklin man was seriously injured in a hit-and-run accident on a Northern Virginia interstate on Sunday morning.

According to Virginia State Police, shortly after 4 a.m., two vehicles collided in the southbound lanes of Interstate 95 just south of Springfield. One of the drivers, the 73-year old Franklin man, was standing beside his blue Ford Taurus when a passing vehicle struck him and his vehicle at about 4:15 a.m.

The driver of the vehicle that hit the man failed to stop and left the scene. State police are seeking the public’s help to locate the vehicle, which is believed to be a large Mercedes sedan or small sport utility vehicle. The vehicle would be missing its passenger-side mirror and passenger-side molding. The hit-and-run vehicle would have also sustained significant damage to its right side and may have blue paint on it from where it struck the victim’s car.

The victim was transported to Fairfax Inova Hospital with serious injuries and remained hospitalized Monday, according to Corinne Geller, the public relations manager for the state police.

Geller said state police are not releasing the victim’s identity at this point because they are still searching for the suspect.

Anyone who may have been in the area of I-95 and witnessed the incident or who might be familiar with the hit-and-run vehicle is asked to please contact the Virginia State Police Fairfax Division at (703) 803-0027 or email the Area 48 Office at Area48@vsp.virginia.gov.
