Surviving Colorado sons mourn parents, young sisters after deadly crash; “I was really just hoping it was a nightmare.”A Thornton family is experiencing deep loss, as two brothers mourn four beloved family members, who were killed in a fiery crash over the weekend.

Family members told CBS Colorado on Monday Francisco Díaz, 49, Beatriz Núñez, 49, Paola Díaz, 15, and Nataly Díaz, 10 all died when they were hit in their vehicle by another driver on Saturday. They leave behind surviving family members Adam and Daniel Díaz, 20 and 22.”We’re really close to our family; we all live together,” Daniel told CBS Colorado.Adam and Daniel are the big brothers in a close-knit family of six. On Saturday evening, their parents, Francisco and Beatriz, took their sisters on a grocery run to Walmart in Thornton. Within minutes of leaving their Thornton family home, the worst case scenario happened.

“I was going to eat, and as soon as I was gonna walk in, I get a notification saying that my little sister Paola has been in a crash — detected SOS,” Daniel said. “That’s when I ran out of the restaurant. I get in my car; I call my brother, tell him if they’re OK.”

“None of them were really answering the phone, so that’s when I headed over,” Adam told CBS Colorado.

Adam rushed to the scene, but his loved ones were already beyond the ability to be rescued by first responders.

“I got there pretty quick, but everything was already in flames. There was nothing they could do,” Adam Díaz said.

All four family members inside the truck lost their lives.
