Thornton, Colorado: Police in Colorado on Thursday captured a man accused of walking calmly into a suburban Denver Walmart and fatally shooting three people at random before driving away.
Scott Ostrem, 47, was taken into custody without incident a day after the shooting following a tip from the public, the Thornton Police Department said.
Police said they have yet to establish a motive for the rampage and that Ostrem had only "a minimal criminal history."
Video broadcast from CBS affiliate KCNC-TV showed the suspect being handcuffed by police against the side of an SUV as FBI agents carrying rifles and wearing body stood by.
KCNC-TV said police SWAT team officers had ringed his last known address in suburban Adams County on Thursday morning when Ostrem
drove past. He was followed by law enforcement and journalists, KCNC-TV reported, and was arrested in the nearby suburb of Westminster after a "quick pursuit."
Police had earlier released a surveillance camera photograph of a middle-aged white man wearing a black jacket and blue jeans. They also published a photo of the red four-door Mitsubishi hatchback he was believed to be driving.
Ostrem "nonchalantly" entered the store in Thornton, about 10 miles (16 km) northeast of downtown Denver, and opened fire on shoppers and employees shortly after 6 pm (8 pm EDT) on Wednesday, police spokesman Victor Avila told reporters.
Two men were killed in the shooting and a woman who was shot was taken to a hospital where she died, according to police. No one else was wounded.
