A verdict could come as soon as Monday for three suspects accused of murdering a man they mistook for a rival gang member.

Rashad Barber, David Wallace and Ryan Bowdery are on trial for the murder of Darius Bottoms on June 13, 2014.

The men were only 16, 19 and 20 years old when they were indicted.

"My only regret is that they didn't have the guidance in their lives that my grandson had in theirs,” said Lenora Flanagan, Bottoms’ grandmother. “Because I feel that if they did, this never would have happened."

The case finally went to trial on August 1, and the jury began deliberating this past Thursday.

Bottoms was the nephew of Atlanta city councilwoman Keisha Lance Bottoms, who is also running for mayor this fall.

Flanagan called the past three years, trying, but said she’s made it through.

"There will always be a hole in our hearts because he is gone and you never know how this effect people until this happens to you," she said. "I'm a Christian and I have faith. that is what has been getting me through."

Photos of Bottoms decorate Flanagan’s home, and she will always wonder about the life he could have lived.

"I won't get to see his grandchildren, I won't get to see him marry," she said. "And most of all, I won't get to see him excel."
