As officers canvassed for clues, reports of more gunfire just blocks away started to come in around 3:46 p.m.
That crime scene stretched across the highway near Lee Street where police found two more victims.
"We realized there was a third victim that was shot at the second scene that actually walked away from that actual scene and winded up collapsing just down the street from that original location," Union City Police Officer Jerome Turner said.
One of the victims, later identified as Byron Davis, was taken to Grady Memorial Hospital and listed in critical condition. Officials confirmed Davis later died as a result of his injuries.
Investigators said Saturday, Calvin Woodard is a person of interest in connection to the shooting of Davis.
