A fire tore through an Aurora house late Wednesday with nine people inside, killing two children and injuring all the others. 

Aurora Fire Rescue firefighters arrived to the house in the 2800 block of South Oakland Circle West around 11:30 p.m. Wednesday night. They found nine occupants in the home.

Two of the victims, a 1-year-old and a 9-year-old, died.

Four children remained in critical condition Thursday. One child and two adults have been treated and released, according to Aurora Fire.

Fire investigators did not release a potential cause Thursday.

When neighbor Nan Page-Stevens woke up to the sound of her barking dog, she saw more emergency response vehicles in her neighborhood than she could count.

She also remembers an image burned in her memory — a firefighter carrying the small, 1-year-old child.

“Out came this big firefighter. He had the baby literally in his arms. He was running to the first ambulance. And now, that baby is gone,” Page-Stevens said.

Though the outside of the house remained seemingly unscathed, the inside bedrooms are in the back of the home, Page-Stevens said. Firefighters had placed ladders on the side of the home to reach the bedrooms on the second floor.

Tiffany Brown, the mother of the two children that died, started a GoFundMe for help. She noted in the description that her five children, brother, two nephews and husband were in the fire. She also wrote on the social media post that her brother has multiple sclerosis.

“They are my life line and now they’re no longer here,” Brown said in her GoFundMe post. She asks for any help and states that now the family is homeless.

Page-Stevens said she heard that two small boys are still in critical condition. One is said to be intubated and the other is undergoing surgery to “clear out his lungs,” she said.

Fire officials declined to comment on the current status of the victims. They had no further updates on the situation, though investigations on the cause of the fire are ongoing.

The American Red Cross Colorado branch told The Denver Gazette they dispatched a disaster action team and have made contact with the victims. They are working to provide support to those affected by the disaster, though they could not provide details.

Page-Stevens said that the entire neighborhood is close and offers their support to the victims.

“We all love each other here,” she said. “Everyone came out to watch responders rescue the residents. Everyone came out to get updates the day after.”

Chairs and flowers line the sidewalk, offering a token of moral support from those nearby. 

“We all just stood there and watched,” Page-Stevens said, tears welling. “What else can you really do?”

Page-Stevens said she believed the mother was at work during the fire. The father, Larry Brown, had exited the house and was being helped for smoke inhalation by responders when Page-Stevens saw the fire unfold.

Aurora Fire officials said the fire was brought under control and searches for any other trapped parties were completed. A dog was located and safely rescued.

“All we can do is pray,” another neighbor added, asking not to be identified.

“Obviously it was really hectic. There were nine patients and the majority were children,” Andrew Logan, a representative from Aurora Fire Rescue, said in a Thursday morning press conference. “It’s never something that I want to stand in front of a camera and address … It is a very difficult situation for first responders and the family themselves.”

Though investigators have yet to determine the exact cause of the fire, they have listed important home safety tips on their website. 

Fire officials suggest that all homeowners should have at least one smoke detector on every floor of homes and batteries should be replaced every year. 

The website also recommends unplugging any electrical device that smells as if it is burning. Don’t overload extensions cords and replace frayed cables.

The department notes that a fire can fully engulf a home within 60 seconds, so it’s crucial to have an escape plan figured out amongst all residents of the home.
