The Dallas Police Department charged a 15-year-old with aggravated assault in the Jan. 11 shooting at a basketball game.
An 18-year-old was seriously injured in the shooting, which happened in the third quarter of a game between South Oak Cliff and Kimball high schools at the Ellis Davis Field House. A Dallas ISD police officer also was grazed by a bullet when she tried to confront the shooter.
The suspect turned himself in Sunday.
DISD spokeswoman Robyn Harris says the shooting broke out during a fight.
