"We don't have no information about nothing. And they never talked to us about anything since this happened. And so I really feel it's not fair. It's just one sided, and it's on their side," explained Brown's sister Gussie Reed.
"It doesn't give the appearance of fairness. It doesn't come off as the district attorney being impartial. It comes off, as, 'Hey, here's a head's up. This is what you need to know,'" said Brown's family attorney Julius Collins.
But District Attorney Greg Edwards said this is part of new Georgia legislation to ensure transparency in officer shooting investigations.
"The Grand Jury is going to be hearing the evidence and they are going to be making the decisions," said Edwards. "So there is no heads up that can be given. The evidence will be the evidence."
Still Robert Lee Brown's family has doubts about justice.
"I hope so, because right now I don't have any closure," explained Reed.
The civil grand jury will begin at 9 a.m. on Tuesday and is expected to last most of the day.
The entire transcript of the hearing and the exhibits shown will be available to the public on Wednesday.
