The presser at which the bill said SJL had been seen at 37SR was definitely premature, IMO, and along with the family's unhelpful publishing of out-of-date photos fixed the idea of SJL as a brunette last seen at Shorrolds.
What I don't understand is why they didn't take the earliest opportunity to correct this. There are good reasons to think that the last sightings of SJL were not at 37SR even if those are correct, but rather, those by BW and now EM, near or in the FPR two hours later. Once those witnesses came forward, why could not the police update their previous account to say WTTEO God love you, the public, for your tremendous response. Thanks to you, we now have witnesses that may place Miss Lamplugh, in her car, near the FPR. Did you see her there? We need to know where she went next, and when, and how she came to leave her car.
That's not embarrassing - that's using exactly the information you appealed for. If the appeal can't be allowed to challenge the 37SR narrative, what's the point? If they "knew" the 37SR story was solid what was the appeal appealing for?
Equally obviously it should have been a cue to wonder who "Mr Kipper"'s local contacts might be and whether SJL was taken into a local house or building. They must have been aware this was likely but wouldn't the EM sighting have been gold dust in identifying it?
Even if for argument's sake EM was found or deemed to have got the day wrong, it shouldn't matter. There's no reason to think SJL had not been about with Mr Kipper before - quite the reverse. So what sort of places did Mr Kipper go, and whom did he meet and know?
