Looks like we have reached the end of the road with the "Irish teenager" thingy and we are yet again veering to wards the "Bash the McCanns" thingy - as we always seem do.
So what momentous conclusions have we reached?
Did or did she not exist?
If she did ... who was she?
If she did not exist ... who invented her ... and for what purpose?
The girl alluded to is clearly meant to be Aoife, IMO, but it seems unlikely that she'd have walked all the way from the restaurant to near 5A for a secret ciggie in the middle of dinner. I suppose it's vaguely possible that she did see two men talking somewhere else or on a different night. However, she made no mention of any such sighting in her statement, and could have simply said she'd gone for a walk if she had. There was no mention of a man with a baby buggy, either, which would have been a fairly obvious detail to notice. There is no other Irish girl in the files who could fit the bill.
At around that time, there were rumours flying around that a security camera showed that none of the T9 had walked up that road in the relevant time frame. This was originally supposed to be an OC cctv, but it later morphed into a different building's security camera. The half-truth in that is that there
was a security camera (which, by the time the police noticed it a week later, had been wiped), but it was around the Smith block. (There was also the Paraiso one, which was nowhere near Block 5 either.)
There was also much mocking during that period of numerous alleged changes in JT's descriptions and general story.
The only purpose of all that that I can see was to discredit JT because the PJ had already decided on their scenario and JT's sighting couldn't be shoe-horned into it.
As I can't find anything to substantiate the Irish ciggie girl even as a half-truth, I'll go with doesn't exist, or at the very least that the two men talking were seen elsewhere and were not Gerry and Jez outside 5A.
