SHARON HILL, Pa. (CBS) — It’s been nearly three months since 8-year-old Fanta Bility was shot and killed by police, and four others were injured by gunfire outside an Academy Park High School football game against Pennsbury in Sharon Hill, Delaware County. Three of the people wounded were hit by gunfire from the officers, while the other was wounded in a shooting near the stadium.

Last week, the Delaware County District Attorney’s office made an arrest in connection to the shooting.

Angelo ‘AJ” Ford, 16, of Sharon Hill was arrested on multiple charges, including first-degree murder, despite Delco District Attorney Jack Stollsteimer previously saying that there’s a “high probability” shots fired by the officers killed Bility.

The other suspect, Hasein Strand, 18, of Collingdale, is currently being sought by law enforcement.

On Thursday, a grand jury of Delco residents will review the entire case in order to determine whether the police officers’ use of deadly force was justified.
