I think this is a good theory. Do you have a theory on what happened prior to the shed theft? The police have said the skeleton/clothes were not in the suitcase all along. Any ideas on what prompted someone to gather those items and put them in the suitcase?
I do have a theory actually CSI.
I believe the child died in a domestic violence incident and we have a dangerously controlling father and terrified mother living somewhere quite remote from other people.
I think after the child was killed they buried her somewhere and the mother stored her clothes in the small case, probably along with some toys, although the police have not said that.
This fits with what we do know - that the items were originally packed into the case very neatly folded.
At some point, well after the body had decomposed, it became either necessary or desirable to move her remains. Perhaps the area was to be tilled and sown, or perhaps she was buried in what had been a quiet area but was now more exposed due to some activity. Perhaps they were moving and the mother couldn't bear to leave the remains behind.
So I believe the bones were recovered and packed into the bag with the precious items.
It could be something the mother has done in secret. A way of keeping her child close perhaps.
Again, this fits with the facts the police have released, that the body did not decompose with the clothing but that the bones were packed into the case later.
For me, the most absurd thing about this case is to think that someone intentionally left the suitcase containing the remains and clothing on the roadside.
I know we can surmise that it was do by a mentally unbalanced person, but that just doesn't fit in with the other things we know.
Bearing in mind that somebody has kept the remains and the clothes somewhere in a zippered suitcase for several years I think we have to assume they were treasured.
If a person really wanted to dispose of them, they have had years to do that. Clothes can be burnt without anyone knowing. Bones that small can be easily scattered anywhere.
I really don't think the person who was keeping these clothes and bones together wanted them disposed of.
Therefore, I can only conclude that they have been taken/stolen.
I said further up that packing the bones into the case could be something the mother has done in secret.
If so, perhaps the father knew nothing of the bones.
What if one day, in a fit of rage, he took the precious suitcase from her and dumped it?
What if he didn't realise at that time that the mother had placed the tiny bones in the case?
What if, once he found out what she had done and that the bones were inside the case, he wanted to recover it, but couldn't find the exact location, so he searched for it over a period of days?
As I say, I am just trying to find a scenario that fits the facts we know.
It is such a bizarre case that it will probably have a very banal solution like the one I am suggesting.
