“I knew they would make an arrest. I believe in God. And I knew that it was going to come to the light,” Craig said.

Police said surveillance footage from the gas station and interviews with witnesses led them to the shooter, but police won’t yet say why the boy allegedly fired the shot.

While Diggs’ parents are relieved police made an arrest, they also know nothing can bring their son back.

“Every day is a battle. My son is gone,” Diggs said. “It hurts, but I know he’s in a better place. I feel it.”

“The loss of T’Rhigi is tragic and senseless. It is my hope that this arrest will bring some sense of comfort and closure to his family,” DeKalb County Police Chief James W. Conroy said in a news release Wednesday.

Because of the alleged shooter’s age, his name is not being released.

Detectives are trying to locate a witness captured by surveillance footage who they said has not come forward. He is a witness and asked to call DeKalb County police, detectives said.
