I've changed my mind completely on this. I think that any links are just coincidence and probably brought about by lifestyle choices not anything meaningful or sinister.
I think that this began as a crime of opportunity.
Hate to say this, but I reckon LE may have lost focus on what this is really about -> William Tyrrell.
I feel they have nothing connecting WS directly to William Tyrrell, and are taking what they can get on Bill, so as not to look so 'empty-handed'.
Praying, as always, that lil William is found, soon, and safe!
