Bill Spedding had the means, motive, and opportunity in this crime. That has yet to be disproved. In any capacity.
And quite honestly, I have yet to hear a theory on this thread, that delivers any resemblance of facts, that accounts for another's potential guilt in this crime. Just 'could be this, might be this, maybe is this'.
I am open to other decent theories, I am not open to remaining generically open.
There is a child abductor and potential murderer out there, roaming free. I think the police know who it is. I think I may be right on the money with this one. If not, some serious other theories that are potential and probable likelihoods could be put forward. Instead of trying to pick apart a pretty strong theory, with factual indicators, that Bill Spedding is behind this crime.
