Authorities in Colorado have identified the 10 victims killed in a mass shooting inside a grocery store on Monday, as well as the alleged gunman.
The attack at a King Soopers in Boulder ended when police took the lone suspect into custody after exchanging fire.
Police have not confirmed a motive. The suspect faces 10 counts of murder.
Boulder Police Chief Maris Herold said the victims were between 20- and 65-years-old at a news conference on Tuesday.
Among the dead was 51-year-old Eric Talley, who was the first police officer to respond to the shooting.
The suspect has been named as 21-year-old Ahmad Al Aliwi Alissa.
The grocery store is located in a busy shopping plaza in Boulder, a north-central Colorado city about 30 miles (50km) away from the state capital of Denver.
The supermarket attack comes less than a week after a mass shooting that left eight dead, including six Asian women, at three spas in Atlanta.
President Joe Biden on Tuesday pledged to “use all the resources at my disposal to keep the American people safe” and called on Congress to pass gun control measures.
“This should not be a partisan issue. It will save lives, American lives. We have to act.”
Mr Biden called for a ban on assault weapons and high-capacity magazines as well as an end to loopholes in background checks – measures he has long supported.
Police identified the 10 victims of the shooting in the early hours of Tuesday.
Their names are:
- Denny Strong, 20
- Neven Stanisic, 23
- Rikki Olds, 25
- Tralona Bartkowiak, 49
- Suzanne Fountain, 59
- Teri Leiker, 51
- Eric Talley, 51
- Kevin Mahoney, 61
- Lynn Murray, 62
- Jody Waters, 65
Chief Herold said the shooting had left her feeling “numb”.
“I live three blocks up the street from that store,” she said. “This is my community.”
She added that her colleague who lost his life in the attack, Mr Talley, was “a very kind man” with seven children, ages five to 18.
“He cared about this community. He cared about the Boulder Police Department. He cared about his family and he was willing to die to protect others,” she said.
