One of the victims left behind a pregnant fiancée – and told her and his mom to run when he saw the gunman open fire.
One was simply shopping with his wife and daughter. Another with her husband.
Thornton police are trying to piece together why a man they believe was the lone gunman “nonchalantly” walked into the Walmart off of Grant Street, took out a handgun and shot and killed three people Wednesday night.
The suspect is now in custody, and on Thursday afternoon, the coroner’s office released the names of the three victims.
There’s no indication that Pamela Marques, 52, Carlos Moreno, 66, and Victor Vasquez, 26, knew one another or the suspect before they died, according to Thornton police.

Marques was from Denver, while Moreno and Vasquez are from unincorporated Adams County.
Moreno leaves behind a wife, three daughters and two granddaughters, his family told 9NEWS. He worked as a handyman at the Auraria Higher Education Center for a little over 18 years.
"Always when I saw him, he was smiling and waving and just had a great attitude about his job," Blaine Nickeson with the Auraria Higher Education Center said. "He'll be sorely missed."
