A gunman is still at large after three people were killed in a Colorado Walmart shooting Wednesday night, police said.
Customers and employees inside the Thornton superstore, located approximately 10 miles north of Denver, fled after shots broke out around 6:30 p.m. local time, police said.
Two men were killed and a woman later died after she was taken to the hospital, according to police. Two others sustained injuries during the evacuation.
An hour after cops descended on Thornton's Town Center, police said there no longer was an active shooter at the scene.
But police still are combing through surveillance footage and interviewing witnesses in the hunt for possible suspects. No one has been taken into custody so far, but police have a person of interest — 47-year-old Scott Ostrem.
Aaron Stephens, 44, said he feared for his life when he heard one shot followed by a burst of gunfire while he was in the self-checkout line, the Denver Post reported.
Crowds formed in the parking lot outside the store, and family members who arrived at the scene screamed with relief when they finally were reunited with their loved ones.
Rep. Ed Perlmutter tweeted: "Devastated to learn that one of our local communities has once again been impacted by gun violence. My thoughts & prayers are with the Thornton community tonight. Thank you to the first responders who acted so quickly."
