Waffle House shooting witness says 'hero' stopped gunman

Chuck Cordero, a customer who witnessed the Waffle House shooting in Tennessee says, a "hero" inside the restaurant wrestled with the shooter until the "gun went flying."

Cordero was sitting in his parked car outside the restaurant when he says he saw the gunman get out of his pickup truck wearing nothing but a jacket and naked from the waist down.

Police have identified Travis Reinking, 29, of Morton, Illinois as a person of interest in the shooting.

Four people were killed and several others were wounded in the shooting.
