Original Story:

Multiple people were shot inside a Walmart Super Center in the Denver suburb, police in Thornton, Colorado, said Wednesday. Two men were killed and a woman was critically injured in the shooting, police confirmed.

It was not clear yet if there have been other victims, as the total number has not been declared by the police.

Thornton Police reported the shooting at approximately 6:30 p.m. local time (8:30 p.m. EDT). About an hour later, they tweeted saying there was not an active shooter "at this time." However, the police did not mention whether a suspect had been apprehended.

"We've got multiple parties down, we're still trying to ascertain what their conditions are," Officer Victor Avila of the Thornton Police Department told Reuters.

The store had been "self-evacuated" by customers and employees, who fled following the gunfire, Avila said. Police are looking for two suspects involved in the incident.

One employee, who has not been identified, told local media he had heard at least five or six shots.

"I started to hear loud pops, and it kept going. Everybody got down, everybody was screaming..." he said.

According to local NBC affiliate 9NEWS, a woman whose son was inside Walmart at the time of the shooting had told her that he had heard almost 30 gunshots and was still inside.

A video posted on Twitter showed the retail outlet, which was situated in a large complex apparently empty except police officers with guns drawn.
