Investigators said a fire that killed a mother and daughter in Yorkville appears to be accidental.

The fire happened last month.

41-year-old Heather Mishlanie and her 7-year-old daughter Taylor Mishlanie were found by firefighters in the upstairs apartment, but did not survive their injuries. As crews attempted to get the fire under control, the roof collapsed.

No firefighters were injured.

While investigators believe the fire was accidental, the cause is still under investigation.
