BOULDER, Colo. (CBS4)– One police officer was among 10 people killed in the King Soopers shooting in Boulder on Monday afternoon. Boulder police rushed to an active shooter call at a King Soopers on Table Mesa Drive near South Broadway about 2:30 p.m.

“I want to say our hearts of this community go out to the victims of this horrific incident,” said an emotional Boulder Police Chief Maris Herold. She identified the officer who died as Eric Talley. She says he was first to arrive at the scene and called his actions “heroic.”

“His life was cut much too short,” said Michael Dougherty, Boulder’s district attorney. He said his office will investigate the crime thoroughly.

He had seven children, ages 5 to 18, Chief Herold said.

The remaining nine victims have not yet been identified.

“Obviously this is a very complex investigation that will take no less than five days to complete,” said Herold.

“We do have a person of interest in custody. That person was injured during the incident and that person is being treated for injuries,” said Boulder Police Cmdr. Kerry Yamaguchi.

Herold said the suspect had a “patrol rifle.”

Police did confirm that the public is not in any danger.

Customers inside the store described the scene as a gunman opened fire.

One man without a shirt on was walked out of the store in handcuffs about an hour after the first call. It appears his right leg was covered in blood. He was led to an ambulance and taken away to a local hospital.

Dozens of law enforcement agencies participated in a procession for Talley at around 7:45 p.m.

Residents from around the area, including Zachary Smith, showed up at the scene to pay their respects.

“It’s a bad day in Boulder,” said Smith. “I’ve lived in Boulder 23 years. I was born and raised here, mom went to CU Boulder. My dad is a police officer in Adams County. I’ve never seen anything like this.”

Smith says the shooting that leaves one officer dead hits especially close to home.

“My dad puts on his uniform every day and that could’ve been him,” Smith said. “He could’ve been the officer that got shot.”
