The Latest on the shooting at a Colorado Walmart (all times local):

9:20 a.m.

Police say a man suspected of fatally shooting three people inside a suburban Denver Walmart tried to flee officers in his car but was blocked by traffic.

Thornton police spokesman Victor Avila said Thursday that 47-year-old Scott Ostrem was arrested without incident after a brief chase that started at a Thornton apartment.

Avila says police received an anonymous tip that led them to the apartment, which is about 5 miles (8 kilometers) from the Walmart store where the shooting took place late Wednesday.

Police took Ostrem into custody after his car was blocked by traffic at an intersection. Avila declined to say if Ostrem was armed.

He says a motive for the shooting is unknown.

Two men died inside the Walmart, which is about 10 miles (16 kilometers) north of Denver in a busy shopping center. A woman died later at a hospital.
