Three people are dead and a manhunt is underway after a gunman opened fire in a Walmart in Colorado early Wednesday evening before leaving the building.
A man suspected of walking into a Walmart store in Colorado and "nonchalantly" shooting to death two men and a woman has been arrested, police said Thursday.
Ostrem, 47, of Denver, was identified Thursday morning as the suspect in Wednesday's shooting. InsideEdition.com's Leigh Scheps (http://twitter.com/LeighTVReporter) has more.
Just before 8 a.m., the 2017 red, four-door Mitsubishi Mirage associated with Ostrem drove past the apartment complex.
SWAT officers who helped with the arrest did use a "flash bang" to distract Ostrem, Avila said. Police are warning civilians to consider Ostrem armed and risky.

The three people who were killed were the only ones who were shot by Ostrem.
It's unclear if the attack is terrorism-related, police said, although they believe it is not. Thornton police said a nationwide extradition homicide warrant has been issued for the 47-year-old Ostrem.
This meant they couldn't send a Walmart employee into the store to immediately review surveillance footage, since police still had to secure the scene and make sure it was safe. The shooting appears random and there are no indications that it was an act of terror, said Thornton police spokesman Victor Avila.
"The employees started screaming and the customers started screaming" as people began to flee the store, he recounted.
The names of the victims have not been released though Tiffany Wilson, Director of Walmart Communications, did confirm that all Walmart staff has been accounted for.
