The state fire marshal is investigating after an elderly woman was hospitalized with burn injuries after a fire engulfed the rear of a home near Antioch Friday afternoon.

The Antioch Fire Department responded around 2:37 p.m. Friday to the 26600 block of West Sycamore Road in unincorporated Antioch for a structure fire.

Antioch Fire Department Battalion Chief Tim Taylor said crews found heavy flames coming from the back corner of a tri-level home.

Smoke was also coming from the roof line of the second floor.

Firefighters made a transitional attack and gained control of the fire, Taylor said.

The home is located in an hour without fire hydrants and crews had to haul water to the scene.

The Round Lake, Grayslake, Salem Lakes, Bristol, Twin Lakes, Fox Lake, McHenry, Newport, Libertyville, Beach Park, Kenosha and Waukegan fire departments assisted.

Firefighters worked for approximately two hours extinguishing the fire and conducting overhaul operations to extinguish hidden fires.

Taylor said the house was deemed uninhabitable but he did not have an estimated damage loss.

The cause of the fire remains under investigation by the Office of the Illinois State Fire Marshal and fire department investigators.
