The two were briefly separated, but officials say Gooden went to a car, got a gun, chased after Foster and shot her.
Authorities then say Gooden jumped on top of Foster and repeatedly beat her in the face and head before leaving the scene and getting rid of the gun.
Foster suffered a fractured femur and perforated femoral artery. She later died at WellStar Cobb Hospital.
Gooden was on the run for two weeks before she was arrested in Charlotte, N.C., and brought back to Georgia. She remained in the Douglas County jail without bond.
In court, Assistant District Attorney Deah Warren said Foster’s family and friends struggle with her loss daily.
“I can only hope that this resolution provides some semblance of closure and a feeling that justice has been served, ” Warren said.
