Sorry to put a fly in your ointment but it is by no means confirmed that the man Tanner claims to have seen was another innocent tourist on his way home from the night crèche.
Andy Redwood refuses to come out and state categorically that to be the case. This I suspect is because the guy isn't sure himself what time he walked past block 5. Also taking into account the fact that he was not walking away from the night crèche which he fails to explain. In addition, a two-year-old is much shorter than a four-year-old and does not fit with Tanner's description.
If there is a simple explanation then why not reveal it?
I am very suspicious of this belated attempt to rule Tanner man out, I just don't buy it!
I don't see the issue.
The Met say they're
almost certain because there's no way of actually proving it, but the guy himself thinks it could well have been him (and possibly his partner or creche people have confirmed it as well). If there had been CCTV footage to corroborate, for example, then maybe they
could have been 100% certain.
The purpose of providing that information wasn't to satisfy armchair detectives, but to emphasise the shift in time focus to get any potential witnesses to try to remember if they'd seen Smithman, or indeed anyone else who may have been carrying a child nearer to 10pm, perhaps even putting a child in a car or even a boat (I've added that for Sadie ;) ) at around that time. Smithman hasn't yet come forward (or hadn't at that point).
