8-year-old Fanta Bility fatally shot after a high school game was likely hit by police officers’ bullets while they returned fire against gunmen during a shootout on Aug 27. According to NBC Philadelphia, while people were leaving the stadium of Academy Park High School in Delaware County, Pennsylvania where Academy Park and Penndbury High School were playing each other, when gunfire started.

Police officials initially said the incident was a drive-by shooting.

According to Delaware County District Attorney Jack Stollsteimer, one person began shooting and some of those shots were directed towards three Sharon Hill officers who were monitoring the crowd while they left the stadium.

“In response to the gunfire, the police officers discharged their service weapons,” Stollsteimer said in a statement the news station reports. “Tragically, our investigation has now determined that there is a high probability that the responsive gunfire of the Sharon Hill Police Officers struck four victims, including the shots that killed 8-year-old Fanta Bility and wounded her sister. The death of Fanta and the wounding of her sister and the other students are a heartbreaking tragedy for her family, her friends, and the entire Delaware County community.”

Stollsteimer added that investigators have yet to arrest those believed to have fired the initial shots. Three people were initially detained and later released from custody. No charges have been filed.

“I am asking again for the community’s help in identifying all the individuals involved in the altercation and the gunfire on Coates Street that led to this tragedy. My staff and I grieve for the Bility family, who I met with again this morning, as well as the other victims,” Stollsteimer said. “My promise to them and to the Sharon Hill community is that we will continue this investigation for as long as it takes until every question is answered and justice is done.”

A local reporter at the game tweeted a photo of players for the visiting team, Pennsbury High School, running for the press box for cover. He later tweeted that coaches for both teams said all players were accounted for. Pennsbury is a high school in Fairless Hills, Bucks County.
