The board concludes that the tragic deaths of the children could not have been predicted or prevented.
However, given the notoriety of the father, the incidents of domestic abuse and visibility of the children, there were some opportunities to get to know the family better although this would not have led to professionals becoming aware that there were plans to deliberately set fire to the house when the children were sleeping.
