Where was any God when this little girl was taken? God does not exist - and if you want to draw strength do it out of the love for your own family not for some imaginery idol.
I do feel sorry for her parents and its painful to watch their suffering, but without a shadow of a doubt they were to blame 100% for what happened to their child.
No parent in their right mind, locks away their money and valuables but leaves access to 3 children under the age of 5. Even if you're only going next door to a neighbour for one minute you'd make sure no-one could attack or steal them, or you keep them in earshot even when they are playing in the garden.
This could highlight how little some parents have to do with the bringing up of young children. If parents are both working full time, giving the responsibility to someone else, out all day and not aware of all the dangers of safety and security then it is a risk. TSafety is something you learn as you go along (something happens every minute to put you on alert with the under fives), and if you only see children part-time then you are not as fully tuned in to the safety and security dangers as those mothers that are.
