A 13-year-old girl was killed in a house fire Thursday, and police are calling the blaze suspicious. We've also discovered that police had been to that same home just hours before the fire.
The victim was identified as Briana Naylor. She was just a week away from her 14th birthday.
A neighbor called 911 around 9:40 a.m. after they saw smoke coming from the back of the home, near 7th Street and Camelback Road
"The minute I came out from my back door, I looked over there and I could see the smoke," says neighbor Gail Hanson.
When firefighters arrived, they found a 13-year-old girl unconscious in her room.
"They were able to bring her out and begin resuscitation efforts on her. She does have some burns and she was in cardiac arrest when she left the scene," says Phoenix Fire Captain Jonathan Jacobs.
The victim was taken to a hospital to be treated for the possible cardiac arrest and some burn injuries from the fire. She later died.
Neighbors told FOX 10 the girl lives with her mother and two younger brothers, but no one else was home during the fire.
Police say officers were called out to the home at 1 a.m. because Briana's mother reported her as a runaway. While officers were there, Briana came back home. But it's not clear what, if anything, that has to do with the blaze.
Hanson says all three kids, the girl and her brothers, should've been in school. But Briana was home alone.
"If I would have known someone was in there, I would have jumped in and gotten her," she says.
Accelerant-sniffing dogs alerted to the presence of accelerants in the home. It's not known if there were working smoke detectors.
Family members gathered Thursday night for a prayer service. They're angry over what happened and say they haven't been given a whole lot of information from police.
"Very young girl, had a whole life ahead of her, whoever did it I hope they come forth," says Briana's aunt Evelyn Hinton.
Homicide and arson investigators spent about 11 hours at the home Thursday. FOX 10's Kelly Hessedal reports.
