The tragic fire that killed a Catoosa county mom and her 5-year old son last week, has been ruled "accidental".     

31 year old Claire Coots and her son riley, perished in the blaze last Thursday morning.  Neighbors heard a couple of explosions as the home burned.

This week, Georgia insurance and fire commission investigators said they could not pinpoint the exact cause of the house fire – but ruled that is was not intentionally set.
