Authorities are investigating the death this week of a 4-year-old girl who had been in foster care in Livingston County.
Kianna Rudesill was pronounced brain dead at 2:35 p.m. Wednesday at OSF Saint Francis Medical Center, Peoria County Coroner Johnna Ingersoll said.
She was maintained on life support until Thursday to allow time for relatives to arrive from out of state, Ingersoll said.
Ingersoll said the death is being investigated by her office, the Livingston County Sheriff's Department and the Illinois Department of Children and Family Services.
The child, who had been in foster care in Cullom for about nine months, experienced seizure-like activity at home before becoming unresponsive, Ingersoll said.
Emergency officials were called to the home about 2:30 p.m. Tuesday. She was taken to OSF St. James-John W. Albrecht Medical Center in Pontiac and later transferred to St. Francis.
An autopsy is scheduled for Friday.
