“We are trying to get her a visa so she can come and say goodbye to him,” Mialik told the television station.
Gwinnett Police released an image from a surveillance camera of the man they believe to be the shooter.
Gwinnett police spokeswoman Cpl. Michele Pihera told Channel 2 the motive is not likely drug related.
One of two armed men grabbed an assault rifle from an SUV and shot Mialik in the neck after the men left the store, Pihera said. The men then drove away.
The alleged shooter is described as 18-25 years old, 5-foot-9 to 6 feet tall, with a slim build and weighing 150 to 170 pounds.
The other man is described as 18-25 and of average height and build.
