One year ago, five people were found dead inside a Commerce City apartment. Initially, no one knew exactly what happened inside apartment 307 at the North Range Crossings Apartments, not even the one person who survived that night.

"I happened to wake up 13 hours later not knowing everyone was gone around me," Cora Marquez said. "I just remembered the baby and the voice of my sister saying that everybody is gone, and my brother wasn't breathing. I tried to perform CPR on my brother, but I didn't know he was gone already."

Now, a year later, Cora opens up about the night that changed her life and the lives of so many others forever. She woke on the afternoon of Feb. 20, 2022, to the sound of her older sister screaming and soon learned that her husband, brother, and three friends were dead.

At first, she thought it was a dream.
