(BERWYN) A woman is in critical condition after being rescued from a fire at her home in west suburban Berwyn.

The blaze started in a rear bedroom of the home in the 1600 block of Ridgeland Avenue about 11:30 a.m., according to Berwyn Fire Chief Denis O’Halloran.

Firefighters searching the home found a woman in her 60s who was having trouble breathing and had suffered burns, O’Halloran said. She was taken to Loyola University Medical Center in critical condition.

No one else was in the home, which sustained moderate smoke and heat damage, he said.

O’Halloran said the cause of the fire remains under investigation, though it doesn’t appear as though it was intentionally set. It was not immediately clear if there were working smoke detectors in the home
