Sharleen R. Smith, of Minooka, was identified by the Kendall County Coroner’s Office. The official cause and manner of death remain under investigation.

The sheriff’s office said it responded around 9:46 a.m. to a house fire in the 15000 block of Hanson Road in unincorporated Seward Township near Minooka.
