US: Indiana shooter killed after injuring 1 at Walmart

25-year-old man opened fire at a Walmart store in Indiana where he once worked, wounding at least one person before officers fatally shot him, authorities said Friday.

The gunman was identified as Ronald Ray Mosley II by Sergeant. Anna Gray of the Evansville Police Department. She said Mosley had previously worked at the store in the city in southwest Indiana.

Officer Taylor Merriss said Friday that a female employee was struck when Mosley opened Thursday night. 

Police didn't immediately release the victim's name or age or the extent of her injuries. But Merriss said she "was able to talk when she was taken away from the scene," the Evansville Courier and Press reported.

Evansville police and Vanderburgh County sheriff's deputies responded to a report of an active shooter in the store at around 10pm Thursday, police said.

Merriss said customers and employees tried to hide or escape before officers arrived and entered in search of the shooter as he stalked through the store. 

Gary said multiple members of law enforcement returned fire during the encounter and the gunman was killed.

Gray said police did not immediately know how many people, aside from the woman employee, that Mosely had shot at, saying there could be additional victims who fled the scene. 

Authorities asked anyone who left the scene with injuries, no matter how small, to contact emergency medical services.

Evansville, a city of around 1,16,000 residents on the Ohio River, is located 172 miles (276 kilometres) southwest of Indianapolis.

A Walmart manager in Chesapeake, Virginia, killed six people in November when he began shooting wildly inside a break room before a routine employee meeting, two days ahead of the Thanksgiving holiday.

Six people were also wounded. The gunman shot and killed himself before officers arrived.
