A handgun was found on scene.”
Police chief Danny Ford told the Associated Press that officers on the scene are currently looking for witnesses, and that more information will be forthcoming.
Casey Staheli, a Walmart spokesperson tells TIME that no Walmart employees were involved with the shooting. “This was an isolated incident in the parking lot and was not an active shooter situation,” Staheli added in an emailed statement.
