UK Hospital officials say a Pike County mother who lost her four children, and boyfriend in a house fire last week has been upgraded to fair condition.
The children's mother, Tammie Tucker, is being treated for severe burns at University of Kentucky Medical Center.
Ricki Gardenhire, a spokeswoman for the Kentucky Public Protection Cabinet which oversees the state Fire Marshal's Office, told the Appalachian News-Express (http://bit.ly/V3lTMJ) that preliminary results of an investigation indicate the heater caused the blaze.
All five victims at the home in the Pike County community of Jonancy were found in a room that contained the heater.
Relatives and neighbors identified the dead as Billy Wilfong and his children, 5-year-old Dakota Lee; 4-year-old Tyler Lane; 2-year-old Cheyenne and Emily, who was 6 months old.
Officials say the home did not contain fire detectors.
