Recently engaged to be married, Ms Bartkowiak was the oldest of four children who moved from California to open the store selling yoga and festival clothing in Boulder, her Michael Bartkowiak, told The New York Times.

He remembered her as “just a beam of light” who lived with her Chihahua, Opal, and had gone to the shopping centre for a prescription when gunned down.

“A lot of people love her. So many people, I couldn’t even begin to fathom. She’s touched a lot of people in her short life,” she added.

Teri Leiker, 51

Teri Leiker worked at the King Soopers grocery store for 30 years and was dating a colleague who was also working at the time of the shooting, friend Lexi Knutson told Reuters.

“Her boyfriend and her had been good friends and began dating in the fall of 2019. He was working yesterday too. He is alive,” Ms Knutson told the outlet.

Ms Knutson has been friends with Ms Leiker since the pair met in 2017 at a University of Colorado program to foster relationships between students and “members of the community with intellectual and developmental disabilities”.

Eric Talley, 51

Eric Talley was an 11-year veteran of the Boulder Police Department and was the first to respond to the mass shooting, according to police chief Maris Herold.

"He's a very kind man. He didn't have to go into policing. He had a profession before this, but he felt a higher calling. And he loved this community," Ms Herold said, according to CNN.

Mr Talley enrolled in the police at the age of 40 in 2010 after a successful career in IT, giving up pay and time with his family to join the academy without a guaranteed job, Jeremy Herko, a lieutenant with the Arapahoe County Sheriff’s Office, told The Washington Post.

He is survived by his wife and seven children aged between seven and 20-years-old, father Homer Talley, said in a statement.

"He had a great sense of humour, he was a prankster… He loved his kids and his family more than anything," Mr Talley said.

"Didn’t surprise me he was the first one there…” Homer Talley

Sister Kristin Stillwell said on Twitter her big brother always wanted to be a pilot if not for his colour blindness.

"My heart is broken. I cannot explain how beautiful he was and what a devastating loss this is to so many. Fly high my sweet brother," she said.

Mr Talley was one of three officers known for wading calf-deep into the water to rescue a family of ducklings from a drainage ditch in 2013, according to the Boulder Daily Camera.
