Authorities say someone stabbed a pregnant Rockford woman to death before a house fire that killed three of her children.
The Rockford Register Star reports new details of the September 17 deaths emerged Friday at a Winnebago County Coroner's Office inquest.
Autopsies determined 27-year-old Keandra-Kirana Austin was 16 weeks pregnant when she was stabbed in the chest. Her body was found in a bedroom alongside the children, ages 9, 6 and 6 months.
There was no sign of trauma to the children, who died of smoke inhalation.
