The attack comes a month after 58 people were killed in a mass-shooting at a country music festival in Las Vegas.
In yet another shooting incident in the US, two men and a woman were killed in a Walmart store in Colorado on Wednesday night as an unidentified gunman fired randomly into a cluster of people in the store before fleeing from the spot.
The incident was confirmed by the Thorton Police Department in a tweet on Wednesday night.
According to eyewitness account, customers started screaming and running for the exits as soon as they heard a series of gun shots.
“You see all these things in the news and you go through it, it’s scary,” Guadalupe Perez, who was inside the store with her young son when the shooting took place, told reporters.
Later on Wednesday, police released a security photograph of a middle-aged white man in a black jacket leaving the Walmart store. They said he fled in a red Mitsubishi Mirage. However, they are yet to announce any arrest or release any major details about the circumstances and motive of the shooting.
The attack comes a month after 58 people were killed in a mass-shooting at a country music festival in Las Vegas. The gunman – identified as 64-year-old Stephen Paddock – committed the crime through the 32nd floor of a nearby hotel by unleashing hundreds of bullets on concert-goers.
The frequent incidents of shooting has renewed calls for stricter gun control in the US, whose citizens own more guns per person than civilians in any other country in the world.
