Two men were killed Wednesday night during a shooting at a Walmart Supercenter in the Denver, Colorado, suburb of Thornton, police said on Twitter.
The Thornton Police Department said one woman was taken to a hospital.
“The shooting happened inside the store,” Officer Victor Avila told CNN. The location was evacuated.
It was unclear whether anyone was in custody, but police said it was not an active shooter situation. Video from CNN affiliates showed a Walmart Supercenter parking lot filled with emergency vehicles.
Jennifer Biglands walked over from her home after her sister called her frantically from inside the store. The sister said she heard seven or eight shots. The woman was so frantic and crying that Jennifer couldn’t understand her, so she passed the phone to an employee who told her there had been an incident and that the woman would need a ride home.
A witness told KTLA sister station FOX 31 in Denver that popping sounds could be heard inside the store before people started to panic.
“I was just picking up my last item and about to head towards the checkout,” the witness said. “Heard two slow pops that sounded like they were coming from the front checkout area and then started to run as about four more shots rang out a little faster. At that point everyone was just running and screaming.”
The witness told FOX 31 that store employees ushered customers toward a backdoor that led to a loading lot in the back of the store, where emergency responders arrived and started getting more people out of the building.
Thornton is just north of Denver.
