When I first joined in the dialogue, there was a tv news crew that walked the path police believed BG and the girls took to the final spot. It was off the bridge, at the north end and directly to the right, "down the hill."
This is what the police had said (I will have to try and find that tv link) and they sounded matter of fact about the route. Oh, and they even panned across to the closeness of the house across the street.
And, because of the tv report, I assumed that this had to be.
Also someone posted a rather straight forward map of the path coming off the bridge at the north end, going right and following a path along the water to the final spot - no water crossing (I cannot remember who or which thread, sorry).
I said at the time that I felt that the girls were on their way back north and BG got on and approached them closer to the north side. Remember I am the one that keeps going on about how that is Abby's jacket in the photo and I surmised that Abby was in front of Libby, on the way back north, and that he was coming south towards them as they were leaving.
But then those two videos came out placing BG and the girls way south on the bridge, closer to the exit at the south end and that video changed my mind completely as to which end they exited the bridge because of the their closeness of the south end and also everyone going south in pictures - it just made sense at that time with the new visual perspective.
Those videos are really indisputable because of all the natural marking points (significant trees, et al.)
And knowing they were so far out, it seemed bizarre that girls would be marched back across the whole length of the bridge towards the populated end. So then the focus became the south end. Because of that I gave up the idea of him passing them and then getting them on the rebound going north, it just seemed too far.
The new theory about the south end has niggled at me but the new visual evidence seemed much easier to justify because of the probability of him marching them back that far across almost the entire length or following them across without them making a run off that bridge and for that house seemed far-fetched to me.
So, did he pass them and, they being creeped out, turned turn back a bit early to get off that bridge?
Or did they go almost the south exit and turn around with him following them the whole time?
Did they think they were probably safe because they were heading back towards a populated area and therefore didn't run?
Did they walk with him.
