After a game of cat-and-mouse, that allegedly involved the suspect flashing a handgun and driving up on a sidewalk to get around the victim’s car, both vehicles stopped at the Greenville Avenue and Amberton Parkway intersection.

When the victim turned on their bright headlights, to see the license plate, they say the suspect leaned out the driver’s side window and fired one shot.
