FAIRFAX COUNTY, Va. (DC News Now) — Firefighters said a girl died in a fire in a home in the Falls Church area of Fairfax County early Tuesday morning.

Fairfax County Fire and Rescue tweeted that it received the call about the fire in the 6600 block of Barrett Rd. around 1:45 a.m.

The girl’s father, Mauricio Arancibia, said he got a call from the hospital around 4 a.m., telling him that 9-year-old Kaysie Anne Arancibia was there.

“Nobody could have avoided it. She was asleep and carbon dioxide, she breathed too much of it and that’s what killed her,” Arancibia told DC News Now. “She was a great child. She had her whole future ahead of her and I pray to God in heaven she’s looking down.”

Arancibia said his daughter started Fourth Grade at Sleepy Hollow Elementary School on Aug. 29.

“She always used to smile and be playful. And it was just a big tragedy what happened. I’m sad. My soul is broken. My heart’s into a million pieces,” he said.

Kaysie Anne lived with her mother and grandmother. Arancibia said it was Kaysie Anne’s grandmother whom crews pulled from the home, in addition to Kaysie Anne. Late Tuesday afternoon, Arancibia said her grandmother was in the intensive care unit at the hospital.

At 10:28 p.m., Fairfax Fire and Rescue tweeted that Patricia Stoderl, 67, had died from her injuries.

Firefighters also brought a dog out from the home. The dog did not survive.

Deputy Chief Lee Warner with Fairfax County Fire and Rescue said the fire seemed to start in the exterior of the home, but the cause wasn’t clear Tuesday afternoon. Members of the fire marshal’s office were working to determine how the fire started.
