Just to add my 25 cents ...

I think it is correct that the theory must come last and by LAST it must come once a viable suspect is in place who meets the standard created by the evidence available.

What is happening here and on other forums is that a viable suspect has not yet come to light. No suspect (that we know of) has yet met the standard set by the body of evidence.

So, in the meantime, we play the websleuthing game of what if so and so met that standard. Sometimes we isolate an item of evidence and a suspect and turn that around and around in our minds to see what we have.

Unfortunately, we are all operating on an inadequate percentage of the facts to REALLY be able to truly put a theory in place ... but we just might be getting close.
