The man is considered the shooting suspect, Vincent said. He left the scene in an SUV and has not been found.
“We are not identifying the victims or suspect at this time as the investigation is ongoing,” Vincent said.
It is not clear how the shooting victim got involved in the couple’s dispute. The woman’s injuries are not considered life-threatening.
The deadly shooting was the first of two incidents of gunfire DeKalb County police investigated Sunday. In the second, a woman was shot in the chest at a Covington Highway motel, just off I-285.
