The Madison County coroner's office says the heat is to blame for the death of a Troy woman. Investigators say that 88-year old Dorothy D. Scott was found dead inside of her home by relatives in the 200 block of East Clay Street on Sunday evening.

The investigation revealed that Scott's air conditioner was in working condition but that the setting had been switched from "cool" to "heat", taking the unit offline. As a result the the interior temperature of the home was approximately 90 degrees, which made Scott, who suffered from a pre-existing heart condition, more susceptible to heat stroke.

Scott is the fourth person to die since the heat wave began on June 28th. The other three deaths were in the city of St. Louis. Funeral arrangements are pending at this time.
