A judge told 47-year-old Scott Ostrem that he is being held for investigation of first-degree murder.

Ostrem was dressed in a blue jumpsuit as he sat in between public defenders.

Police have not said if they have discovered a motive for the shooting.

Authorities say Ostrem walked into the Walmart Wednesday evening in the largely blue-collar suburb of Thornton and opened fire.

He was arrested the next day.

Ostrem worked for a roofing company and his boss has said he was a good employee. Neighbors of Ostrem described him as a rude loner who sometimes carried a shotgun.
