Investigators said they arrested a 15-year-old boy and have charged him with murder in the case.
T'Rhigi's parents told WSB-TV's Justin Wilfon that they were stunned to hear that police believe their child was killed by another child.
“That’s sad. People need to learn how to keep their children in their house, in school,” said T’Rhigi’s mother, Rashonda Craig.
DeKalb County police believe the teenager shot and killed T’Rhigi as he rode past the gas station in his mother’s car on Easter Sunday.
“I don’t know how to even come at that. A 15-year-old boy? Like, I’m just glad they found him, that’s it,” said T’Rhigi’s father, Jamel Diggs.
Diggs' parents told Wilfon they were confident police would find their son's killer.
“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 won’t yet say why they believe the teen 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.
