Firefighters rescued a woman trapped in a house fire in Algonquin Thursday afternoon and she was flown to a hospital with life-threatening injuries, officials said.

The Algonquin-Lake in the Hills Fire Protection District responded around 3:02 p.m. Thursday to the 1-100 block of Alice Lane in Algonquin for a report of a structure fire.

Fire crews arrived on scene in approximately one minute after being dispatched and found a ranch-style home with heavy fire coming from the front of the structure.

Algonquin-Lake in the Hills Fire Protection District Deputy Chief John Knebl said that crews initiated an aggressive interior attack and searched for the resident who was reported to still be inside the home.

“Crews encountered a difficult search due to hoarder like conditions of the home and the large volume of smoke and fire,” Knebl said in a statement.

Firefighters rescued the victim from the home around 3:20 p.m. and transported her by ambulance to Northwestern Medicine Hospital in Huntley with life-threatening injuries.

The woman was then transferred by helicopter to Loyola University Medical Center in Maywood where her current condition is unknown, Knebl said.

No firefighters were injured. Firefighters from Cary, Carpentersville, East Dundee, Palatine, McHenry, Huntley, Crystal Lake, Barrington-Countryside and Fox River Grove assisted.

The cause of the fire is under investigation with assistance from the Office of the State Fire Marshall. A damage estimate is not yet available.
