An 18-year-old was shot twice and a 12-year-old bystander was shot in the back.An officer responding to the scene then shot and killed 21-year-old Emantic Fitzgerald Bradford, Jr of Hueytown who police said was fleeing the scene and brandishing a weapon. Police initially told reporters they thought Bradford had shot the teen after a fight but retracted that statement on Friday night.Breaking: At least three people injured after a shooting at Riverchase Galleria in Hoover, Alabama.

Joiner said she heard six or seven shots and was ordered, along with some other shoppers, into a supply closet for cover."It was terrifying," Joiner said.A woman who described herself as the mother of the injured 12-year-old posted on social media that the girl was on a Black Friday shopping trip with other family members when the shooting happened, and didn't immediately realise that the pain in her back was from a bullet."She was hurting a lot, but very brave and positive as always," the mother wrote after seeing the girl when she arrived at a hospital.Hoover police said on Friday morning that the girl was in stable condition.The officer who shot the gunman was placed on administrative leave while the authorities investigate the shooting. The officer's name was not released. The officers were not hurt.The mall, located in the Birmingham suburb of Hoover, reopened at 06:00 on Friday, a Riverchase Galleria mall security officer said. It bills itself as the largest enclosed shopping centre in Alabama, with more than 150 stores.Hoover police had asked the Jefferson County Sheriff's Office to investigate the shooting, but the sheriff's office turned it over to the Alabama Law Enforcement Agency because a witness is closely related to a member of the sheriff's office.
