Original story: 

Police in Colorado were searching Thursday for Scott Ostrem, the suspect identified in Wednesday’s shooting at a Walmart store. A photo of Ostrem was circulated on social media, asking the public to look out for the man considered “armed and dangerous.”

Ostrem is believed to be the man who “nonchalantly” opened fire at a Walmart in the Denver suburb of Thornton, Colorado Wednesday, killing three people. A nationwide extradition homicide warrant was issued for the 47-year-old.

The suspect apparently walked into the Walmart Wednesday just after 6 p.m., where he began firing a handgun. Police called the shooting that killed two men and one woman "random." Authorities said they had no indications that the incident was terror-related and had not yet discerned a motive for the attack, ABC News reported

"As of right now we can't rule anything out," said Thornton police spokesman Victor Avila, according to KCNC-TV. "However we don't have any indication right now of anyone claiming to have taken responsibility for anything, as of right now."

Ostrem appeared in the photo released by police wearing a black jacket, blue jeans and a maroon shirt. Authorities said they were also searching for a red four-door Mitsubishi Mirage with the license plate 882TQB. Anyone with information or who sees Ostrem was asked to call 911.
