It's hard to believe that he has walked home because as far as we know:
-He could not walk out of that area without being seen on CCTV. One person (I think a relation of Corrie's) was on the news and said something along the lines of - it is possible to walk out, but he'd have to position himself very well and basically he didn't think that likely at all.
-I don't believe there has been anybody that has come forward that has been sure they saw Corrie after he disappeared off camera? No sightings?
-It is a ruddy long way home. It is PITCH BLACK the vast majority of the way. You could not walk home.....you would not be able to see a thing, you would end up walking into a ditch.....which may even explain it, but surely a guy in the army could get himself out a ditch.
-I can't really see how he could accidently get killed on the walk home. Maybe a hit and run, taking the body with them. In Great Livermere, which is a village on the most likely route (IMO) that he would have walked home, there is a lake of some kind. It seems people sometimes end up going missing and they are in water, but I can't understand how someone just gets lost walks into water and drowns. There is also a weird looking sandy area with lines running towards a centre point - what is that place?
I understand he may have got a lift part of the way home, but still not sure how you die on that journey home, or where you could be dropped off that is lit up enough to walk home.....I don't see any roads with lights on them around there.
People have commented that they want people to go off facts etc, which I understand......
So going off facts.....walking home - does it make sense?
Personally I would more or less rule it out.
