The shooting happened on Dec. 28 outside the Dave and Buster's at Concord Mills Mall.
The investigation revealed Black was in a verbal altercation with a 16-year-old boy in the mall near GameStop. The teen saw Black manipulating a gun in his clothes.
Police said Black and the teen were told to leave the mall at closing time. They exited Dave and Buster's into the parking lot when Black began to fire in his direction, striking two boys and 13-year-old Aveanna Propst.
Propst died at the scene. The two boys had non-life-threatening injuries.
