Three dead after shooting at a Colorado Walmart; suspect arrested

aijohn784/iStock/Thinkstock(THORNTON, Colo.) -- The man wanted for a deadly shooting at a Walmart in Colorado on Wednesday night has been arrested after an hourslong manhunt, police said.

The suspect, identified as 47-year-old Scott Ostrem, was taken into custody Thursday morning, according to the Thornton Police Department. He was considered armed and dangerous while on the run, police said.

Two men and one woman were killed in what police described as a random shooting.

The suspect was wearing a black jacket, a maroon shirt and jeans when he nonchalantly walked in the front door of the Walmart in the Denver suburb of Thornton and opened fire with a handgun, targeting people in the front of the store near the registers. Ostrem then exited the store, got into a red Mitsubishi Mirage and fled the scene, police said after reviewing security footage from the store.

Police released a surveillance photo of the suspect and his car late Wednesday.

Officials said they can't rule out terrorism but that there are no indications it is terrorism-related. Police said they have no motive in the shooting.

The Thornton Police Department first tweeted about the shooting at 6:27 p.m. MT, writing, "Shooting just occurred at Walmart, 9900 Grant St, multiple parties down. Please stay away from the area."

The department later tweeted, "At this time this is NOT an active shooter. Active crime scene. We will update as info becomes available."
