Why on earth didn't her dad call the child's mother as soon as she was missing?
I would infer from this that she was from a chaotic household.
Sadly, I think it is because the family is involved.
Jesus Christ. A child has died. A family is grieving. And, once again, people think it's ok to pick over less than perfect reactions, play amature psychologist and think they are bloody Columbo all of a sudden.
We, the general public, will be told about events if and when it's appropriate. Meantime let's bear in mind that a grieving family are already going through hell right now and could well be reading this.
