The family of Sammie Davis Jr. had no immediate reaction to David Cooke's ruling Tuesday.
At the home of his sister, Cheryl Davis, a printed sign taped to a door said, "We have no information and we have no comment."
A man who answered the door also told 13WMAZ's Tom George that the family had not immediate comment.
The family's attorney, Forrest Johnson, also had no comment.
He said he plans to review the GBI case file first.
Johnson said he plans to meet with the Davis family soon to review their next step.
The family says they're considering filing a civil suit in the shooting.
In a previous interview with 13WMAZ, Davis said she had warned her brother not to go to Kroger, and had expressed concern that he might even be killed one day.
She said when the decision from the GBI came down, she predicted there would not be large scale riots over her brother's death. She said Macon was "too apathetic" and "the only people marching would be my family and a handful of others."
