A gunman opened fire at a Colorado supermarket on Monday, killing 10 people including a police officer, authorities said. One person was taken into custody at the Boulder scene, where police said there was no continuing threat to the public.

Boulder Police Chief Maris Herold identified the slain officer as 51 years old Eric Talley, who had been with the department since 2010.

Boulder County District Attorney Michael Dougherty said Talley’s life had been “far too short” and said a “careful investigation was already underway.”

No other victim has been identified.

Dougherty said the person detained was the shooter.

CBS Denver helicopter footage captured authorities escorting a handcuffed shirtless man who appeared to have a bleeding leg from the scene, but authorities have not confirmed whether the man is the suspect.

Witnesses described a chaotic scene as several loud bangs went off in the store. One man said he initially thought someone had dropped something, but by the third hit everyone started running.

“I can’t believe this is happening in Boulder,” he told CBS Denver.
