Investigators on Thursday released surveillance photos of a man accused of gunning down two people last week in the parking lot of a Smyrna shopping center.

The fatal shooting occurred about 5:45 p.m. July 16 in the Cumberland Marketplace strip mall along Cobb Parkway. According to police, Ronald Green and Clifton “Casey” Emmert, both of Marietta, were shot and killed in an “ambush-style” attack.

It’s still unclear what prompted the shooting.

Police are still searching for the suspect, who fled the scene in a dark gray Toyota Camry with a “tag applied for” license plate, Smyrna police spokesman Sgt. Louis Defense said. The man was last seen wearing a red hoodie, fitted black jeans and red and white sneakers, police said.
