Three people are dead—including the shooter—after a shooting at a Walmart store in Duncan, Oklahoma, reports the Duncan Banner. It appears a male shooter with a semiautomatic handgun killed a man and a woman who were inside a car in the store parking lot. Fox 25 reports that the shooting stemmed from a domestic dispute between a husband and wife. "Two were in a car, one’s out beside the car,” said Duncan Police Chief Danny Ford. "We have multiple gunshots to the windshield." Police have not said how the shooter died, but the pistol was found lying beside him. (The shooting follows a mass shooting at a Texas Walmart in August that left 22 dead.)
