The coroner says a forensic dentist confirmed 48 year old Christy Stone, of Lincoln, died as result of the fire.
She was found around 3 a.m. Saturday morning in the north parking lot of State Farm's corporate headquarters in Bloomington.
Video evidence shows Stone never left her vehicle after arriving in the unoccupied lot.
Authorities say she has never been an employee of State Farm.
It is unclear how the fire began.
