Fire investigators say the cause of a fire that killed a Heath three-year-old will remain undetermined.

However, according to Shane Cartmill with State Fire Marshal's Office, they cannot rule out a child playing with a lighter as the possible cause of the fire that killed Brenden Fown.

The fire at 152 Irving Wick Drive on February 11, 2010 started in a bedroom on the eastside of the trailer home.

Investigators say smoke detectors were in the home, but none were found...
