Gwinnett police are hunting for a hit-and-run driver who seriously injured a pedestrian Sunday in Peachtree Corners.

The pedestrian was struck by a “four-door passenger vehicle” in front of a Quiktrip on Peachtree Corners Circle, Cpl. Deon Washington said Tuesday. The suspect vehicle was described as a champagne or white four door passenger vehicle with dark tinted windows and should be damaged on the front bumper, hood and windshield.

Investigators hope to improve on that description by locating another witness. They believe a taxi driver may have witnessed the crash and need help locating the cabbie who was driving a newer model Honda Civic with a decal on the passenger door that appears oval with red or orange writing, Washington said.

Anyone with information on either car or driver is asked to contact the Accident Investigation Unit hotline at 678-442-5653.
