"They were playing basketball, and a ball rolled into his yard. They went to go and get it. It was just crazy," said Jonathan Robertson, who lives in the Gaston County neighbourhood. "We just never expected it in a million years. We never expected anybody would break a gun out amongst all those kids."
Police said the suspect went inside his home and came out with a gun before he fired indiscriminately at neighbours. Mr William and his daughter were struck as parents were rushing to gather their children.
The child has since spoken out about the shooting in an interview with a local ABC news channel.
