This from the Palatine Fire Department:

On Monday, April 15, 2013 at 5:09 P.M., the Palatine Fire Department responded to a second floor apartment fire with reports of children trapped inside.  Palatine police officers arrived first and confirmed one occupant was still unaccounted for.  The first arriving fire department units found fire, heavy heat and smoke as they entered the apartment.  As one fire crew worked to extinguish the fire, another crew searched the two bedroom apartment and found a conscious, 13 year old female trapped in a bathroom behind a closed door.  The victim was carried from the building and immediately taken to Northwest Community Hospital for medical care.  The fire was under control within 20 minutes and was contained to a single apartment.  The apartment was heavily damaged and deemed uninhabitable but no other apartments were affected.  The cause of the fire is under investigation by the Palatine Fire Department and the damage is estimated at $75,000.
