NORFOLK, Va. (WAVY) — A 16-year-old girl has died a week after she had been injured in a fire on Galveston Boulevard, and another person injured in a February fire on Courtney Avenue has also died, Norfolk Fire-Rescue said.

That has fire officials concerned.

The fire victim from the Galveston Boulevard fire on March 12 died early Saturday morning. According to previous coverage, the victim was unable to escape the home after fire blocked access to the stairs. Three others were also hurt during this fire.

In addition to that death, another fire victim from the Courtney Avenue fire on Feb. 21 died Monday morning.

“From the most recent fires that we’ve had lately, it’s the same causes — unattended cooking, discarded smoking materials, and not even in a proper place, candles being used near flammable materials, space heaters being used and flammable materials unattended, things of that nature,” said Norfolk Fire-Rescue Battalion Chief Glen Williams.

Williams recalled three Norfolk police officers going into this Galveston Boulevard home to help rescue the people inside.

“When the call came out to 911, those three officers happened to be very close to that area,” he said. “They were the first ones on scene and they did everything they could.”

The Fire Marshal’s Office is working to complete both investigations and notify the State Fire Marshal.

NFR rescued three fire victims from separate incidents over the last few months and there is still one fire victim in a local hospital with life-threatening injuries.

“These incidents are a reminder of the importance of having working smoke detectors, practicing an emergency evacuation, and other things you can do to protect yourself in the event of a fire,” Norfolk Fire-Rescue said.

And Williams encourages all families to have discussions about planning fire escape routes. This can include fire ladders for upper floors, and familiarizing yourself with ways to get out of the home in an emergency.

“The whole thing is planning, just taking a few minutes, walking around the home with your family members and just saying, ‘what would we do in this case,'” Williams said. “And just that preparation alone will save lives.”
