Not quite sure where I'm going to go with this, or whether I'm going to explain this meaningfully, but let's have a go.
I've been mulling over the whole events of that evening and night, and Corrie's response and behaviour in relation to them, and I wonder if what we are seeing is a constellation of behaviours that we could term high risk.
He's left behind by his mates when they go into town. Why? Was it a genuine misunderstanding or was it an agreement of sorts, maybe tacit, to leave him behind?
If it was deliberate - why? Did they simply not like him very much, or has his behaviour on previous occasions been such that he was something of a liability, eg causing confrontations or other aggro? Did his mates have to pull him out of confrontations or other awkward situations?
Corrie then drives into town on his own and sits in his car drinking for an hour alone. I think I've seen a mention of it being vodka, which almost certainly means he's swigging it out of the bottle.
He then goes on a single pub crawl looking for his mates. Maybe they didn't decide before leaving where they were going, or maybe they did but didn't tell him. If the latter, what does that suggest?
By the time he catches up with them he's been in two other bars already. Within half an hour he's thrown out of FLEX. Why? Was he drunk enough that night to be chucked out of somewhere people were drinking, possibly to excess? Or had he been ejected on a previous occasion and the bouncers suddenly recognised him as a previous problem?
Did he have a previous pattern of behaviour which both got him thrown out of pubs/clubs and maybe meant his mates preferred to leave him behind?
Having been thrown out of FLEX he goes to a takeaway and fills up on junk food.
Then he finds a doorway and sits there for several hours, possibly sleeping, possibly messing about with his phone, possibly various things.
Finally, he goes into a dead end bin area and vanishes. The suggestion is that he has got into a car with someone who may be known to him or a complete stranger - either way neither driver has come forward.
Exit Corrie.
Several threads ago I wondered if Corrie's behaviour was reckless, maybe out of control. I now wonder if taken as a whole it could be described as high risk in the sense that it made him seriously vulnerable to being murdered (if that is what has happened). We readily describe engaging in prostitution, drug-taking or hitch-hiking as being high risk behaviours by high risk victims, and while we have no evidence that he was engaging in any of those behaviours we don't have any he wasn't, either.
We've discussed the possibility that, during the two hours he sat in the doorway, he was arranging a hookup, whether straight or gay.
In this latest thread the question of drug-use or dealing has come up.
If he got into a car in the bin area, it's increasingly likely that either the driver was a stranger (the hookup possibility) or someone he knew but whom he shouldn't have trusted. Again, this driver has not come forward.
The only other thing I can think of is that maybe he'd been borrowing money from a loan shark and was unable to pay it back. That would also be high risk behaviour.
Not sure if I've explained my thoughts very well. It just seems to me that Corrie's judgement was off kilter, and his behaviour in some respects risky. Not in an immediate sense but in the sense that sooner or later something was going to go very badly wrong, and that maybe the extrovert, smiling young man of the selfies was hiding something very different indeed.
