I've got a few uncertainties, which maybe you can put me straight on, there's a lot of discussion so I might have missed some of the facts.
It's been reported that PRs car was seen arriving at Oak Road with him and Libby, but only leaving with him. We don't know what that looks like do we? The only specifics I've heard is that they were both seen getting into the car on Raglan Street, and only one figure getting out of it when it returned to Raglan Street. We don't know if cameras actually caught the activity at the car on Oak Road? Is it possible then that Libby WAS put in the boot, and removed on visit #3?
Having seen the toing and froing by the bus stop, that took quite some time. Although he may not have been as aggressive there as he would have in a more secluded area, for fear of drawing too much attention. The camera is a long way from the figures at the bus stop, but when they are directly in front of the illuminated panel, the distance between their bodies and the movement in unison both in a stooped position undoubtedly looks like one tugging the other by the arm while the other is trying to pull away.
What is happening while he is sitting in his car? Is this when the 3 Romanians are knocking their car window at her? (If that happened). And also when she's trying other car doors? (If that happened). Although he says he was talking to her at that time, telling her that's not his car. But then he says he goes back to find her and she is sitting on the pavement. Perhaps that comes before the trying of car door handles?
After seeing the CCTV of the struggle between them at the bus stop, I'm now having difficulty with the short space of time for rape, murder and placement in the river (even if 2 happened simultaneously). Even if it's possible that Libby was placed in the boot until trip #3, 4 minutes surely isn't long enough to get her to the river. If 4 minutes isn't long enough to get her, unconscious, to the river and get back to the car, I also can't see how 7.5 minutes could be long enough to both get out of the car, walk nearer to the river (especially in the manner Libby was walking), have a struggle, rape and murder, place her in the river and return to the car
