So, sorry, but you have not yet provided any evidence as of yet that there was not a witness as stated by LE. I wish you would, as I am open minded, but I do rely on facts, not personal judgement.
I don't have the kind of proof that would convince you, other than stuff you've already dismissed (scanner etc) and the fact that this was *never* brought up again in any MSM or press release I've seen. I'll admit I hadn't seen that single (vague) comment before, but that's because it was apparently never brought up again by LE, unless they meant the Mom, who was the only "witness" as far as the official record goes.
So we're at "agree to disagree".
