This is probably more of a reddit thread than a HN thread, but it seems unlikely that he would make up a story about a robbery in that case.

Or was it the butler?

Truth is in these situations we don't know so no one outside of the case should speculate.

I feel the tendency to turn criminal cases into public spectacles does more harm and disservice to justice than anything else. The public has no business passing judgement or deciding for themselves. Leave them out of it.
