Suspect walked off job hours before Colorado Walmart attack
THORNTON, Colo. — A man accused of opening fire inside a suburban Denver Walmart, killing three people, abruptly walked away from his roofing company job hours before the attack, his former boss said Thursday.
Scott Ostrem’s employer and neighbours painted a somewhat dueling portrait of the suspect.
Ostrem worked at a metal fabrication shop for the last three years without any problems, said David Heidt of B&M Roofing. He called Ostrem a quiet worker who was skilled at making metal flashing for roofs. But midmorning Wednesday, he left his work station without explanation.
Two men and a woman were killed at the store that evening.
