Talley was the first to respond to the scene and was fatally shot, Boulder Police Chief Maris Herold said.
Talley had been with the police department since 2010, according to Herold. She called his actions in responding to the incident "heroic."
"My heart goes out to the victims of this incident and I'm grateful for the police officers who responded," she said. "I am so sorry about the loss of Officer Talley."
Local, state, and federal authorities responded to the incident, including the FBI and ATF. The investigation is ongoing, and it will likely take at least five days to complete, Herold said.
However, she added that "I want to reassure the community that they are safe."
The Boulder Police Department is working to identify the other nine victims of the shooting and notify next of kin, officials said.
Police said the suspect — who was identified as a male — is in custody and was injured during the shooting.
"We had a very tragic incident today here at the King Soopers. There was loss of life. We had multiple people who were killed in this incident and I'm sorry to have to report that one of them was a Boulder police officer," Yamaguchi previously told reporters in the press conference.
According to CNN, a news helicopter was able to capture video of a shirtless man with what appeared to be blood on his arm and right leg taken by police from the supermarket in handcuffs and loaded into an ambulance.
It's unclear if the man was involved in the shooting.
A shopper who was inside the King Soopers when gunfire broke told The Denver Post the shooter entered the building, "let off a couple of shots, then was silent, and then he let off a couple more."
"He wasn't spraying," the witness said.
Another witness told KCNC-TV that they heard "15 to 20" gunshots within a matter of seconds.
Rep. Joe Neguse, who represents Boulder, said in a statement that he is praying for the community and "all of the first responders and law enforcements responding to this terrible incident."
"Words can do no justice to the tragedy that has unfolded this afternoon," Boulder Mayor Sam Weaver tweeted. "Our community will soon grieve our losses, and begin our healing. Our brave police officers and first responders have the gratitude of our entire city.
Colorado Governor Jared Polis also released a statement in the wake of the incident, writing on Twitter, "Like my fellow Coloradans, I am closely watching unfolding events at King Soopers in Boulder. My prayers are with our fellow Coloradans in this time of sadness and grief as we learn more about the extent of the tragedy."
