At least three people are dead after a Monday morning shooting at an Oklahoma Walmart and the shooter is among the dead, authorities confirmed.
The bodies of one woman and one man were found inside the car, with another dead man found outside the car, according to the Duncan Police Department.
Authorities did not immediately describe a motivation for the shooting. However, Police Chief Danny Ford said that investigators believe the gunman shot the male and female victims and then turned the gun on himself.
Stephens County District Attorney Jason Hicks authorities said during the news conference Monday afternoon that there was never an active shooter inside the store and he described the shooting as an isolated incident.
However, family members told local media that the shooting was the result of a domestic dispute between a husband and wife.
According to the witnesses the suspect shot the two people inside the car before an armed shopper approached with a gun—prompting him to shoot himself.
This is the third fatal shooting incident at the retailer in five months and the latest in a string of gun violence across the United States.
Walmart has become a focal point in the national debate over gun violence. Last week, its superstore near the Mexican border in El Paso reopened, three months after a gunman reportedly targeted Hispanic shoppers at the site and killed 22 people in early August.
In recent months, and in light of the violence, Walmart said it was reducing its gun and ammunition sales and was requesting that shoppers not carry their weapons into its stores.
