One dead and 12 injured in Tennessee supermarket shooting

Police did not say whether the assailant was a Kroger employee

One person has been killed and at least 12 others injured when a lone gunman opened fire on Thursday at a supermarket in suburban Memphis, Tennessee, before the suspect was found dead from an apparently self-inflicted gunshot wound, a US police chief said.

Law enforcement officers swarmed to the scene just after the shooting unfolded at a Kroger grocery store in Collierville, Tennessee, and began helping victims and others found hiding inside the supermarket, Collierville Police Chief Dale Lane told reporters.
