A 77-year-old woman has died in the hospital following a house fire that also injured a dog in Lake Barrington early Friday morning.

The Lake Barrington woman, whose name has not yet been released, was pronounced dead at 3:50 p.m. Friday at Loyola University Medical Center, according to the Cook County Medical Examiner’s Office.

The Wauconda Fire District responded around 4:46 a.m. Friday to the Lake Barrington Shores community in the 1100 block of Oak Hill Road in Lake Barrington for a report of a structure fire.

One of the residents called 911 and firefighters arrived to find all occupants, including the 77-year-old woman, outside of the home.

Smoke detectors were activated and fire crews found heavy smoke on the second floor coming from one of the bedrooms. A hose line was used and the fire was declared under control by 5:25 a.m.

Paramedics transported the 77-year-old woman with burn injuries to Advocate Good Shepherd Hospital in Barrington in critical condition before she was transferred to Loyola University Medical Center, where she died.

Firefighters rescued a dog and gave it oxygen before a family member transported it to a local veterinarian for treatment.

Firefighters used approximately 200 gallons of water on the fire and damage was estimated at $125,000. The cause of the fire is still under investigation but fire investigators believe it was accidental.

Firefighters from Lake Zurich, Nunda-Rural, Barrington, Barrington-Countryside, Long Grove, Buffalo Grove, Woodstock, Fox River Grove, and Algonquin assisted during the call.
