Witnesses said the girls were hanging out in Cooper Park when shots came from across the street, and the girls were injured.

Beverly Wilson Ellison said, “I heard four to six gunshots – to me – it sounded like four to six rapid gunshots. Like, four then maybe two maybe two seconds later, but all together in the same 10-second timeframe.”
