ROCKVILLE, Md. (WUSA9) -- An 81-year-old woman has died after a fire at a Rockville home on Thursday morning.
She was at the home in the 4600 block of Iris Street with her son when the fire started in the basement.
Fire officials say the man ran out of the house and called for help. That's when he realized his mother was trapped inside the house.
"The survivability profile of this fire when first units arrived was poor," said a Montgomery County fire official. "There was smoke pouring from every opening."
Flames engulfed the stairwell leading to the second floor where the elderly woman was trapped. Firefighters used a complicated rescue technique to get her out.
The they had to enter over ground ladders. The second floor window was removed and then down ground ladder," said a fire official.
The woman suffered from smoke inhalation and other injuries. She died hours after the rescue.
We're told the woman's adult son was not hurt in the fire.
Two firefighters suffered minor injuries, says Montgomery County Fire and Rescue Services spokesperson Pete Piringer.
Utility crews had to be called to the scene after a gas burp reignited the fire. The cause is still under investigation.
A fire department spokesperson says the home did not have a smoke detector.
More than 100 firefighters and 30 units responded to the fire.
