@James
I'm not quite understanding option C and the 3 explanations? Could you dumb it down for me a little?
i.e. If he refused the lift in #1 (and said/indicated he was walking home) then how could any attacker know he would be at those bins at 03:30 ~two hours later? Sorry if I'm completely missing the point here...
I don't know how any attacker could have known he'd be there at 3.30am.
So it's really not a case of dumbing down anything.
But the reason I don't know, is because
even if it were possible to trace all the people the CCTV saw him talk with, no one would have any idea what conversations they'd had.
Someone could ask them, if they had contacted everyone he had spoken to face to face that night...or earlier.
And they could tell us. But we wouldn't know. We'd hope we got the truth.
So
IF someone had arranged something. And that meeting went ahead... they wouldn't be wanting it known, because clearly, that has led to Corrie's disappearance.
But say that was "a lift". We can only speculate that "he was getting a lift" because.....
He was still in town....because we can see him
He wasn't going to drive....because he was over the limit and like his car and his licence.
He wasn't going to walk...because he never had.
And he'd not got a taxi.....because we can see him.
We can only speculate that "he'd not got a taxi"....only because
he'd not got a taxi earlier.
It doesn't mean
he was not going to get a taxi later on.
It's speculation of course, becausewe don't know.
