I'm pages behind again but about this sketch issue, just occurred to me that
1. At the time of the newborn investigation, they were trying to identify EVERYONE in the area, it was only after a great deal of investigating that they could begin to pair people and telephones and who was where seeing whom.
Let's say 10 iindividuals reported seeing 3 girls, is that 30 girls or just the same 3? Along those lines, LE had the descriptions from the juveniles -- either they saw 1 man, perceived slightly differently -- or it was 2 men. But if they were all together at the time, it's notable than none saw two men so LE likely reached the obvious conclusion -- they all saw the same one man, wearing dark clothing, seemingly not too friendly. In time, RA would not be ELIMINATED from that description. At the time, that man would be a fair match to one Libby videoed whose trajectory was in step.
Meanwhile BB reported seeing a man. And apparently she couldn't really give an age. Settled on a wide range. We won't know unless she clarifies under oath. Poofy hair might have led her to think not 50, 60, older. Just being on the platform may have entered her calculus. Young enough to dare to cross, maybe not something an older person, in her mind, would do.
Amd when LE first encountered the two descriptions, the three way, in general accord one and the one BB gave, they might have expected that two be two differenr men until realizing that the OBG seen by the juveniles would have been progressing forward right in line with the OBG in Libby's video.
And that makes BB's YBG sighting a variation in description but the same man. YBG had to be OBG because of timing. No one saw a second man.
RA himself was consistent with that. He didn't see another man there.
So why the discrepancy? Between OBG and YBG?
Maybe RA is responsible for that.
Perhaps HE altered his appearance. Pulled his hood up tight. If it was fur rimmed, from her vantage, BB might not gave been able to see definition. Just shape, shade, impression. Perhaps a fur hood gave the figure a very poofy head.
If Abby and Libby first encountered RA not too far from the first platform, it seems he did or said something that was creepy to them. If Abby said, is he behind me?, it suggests she had seen him prior. It was a remarkably nice day. Would it have been WEIRD to see a grown man, on the bridge, with maybe a fur hood pulled over his head and a face cover? Half bank robber.
IMO then there was a time LE thought the juveniles saw one man and BB saw different one, and a time when data synthesized, they realized it HAD TO BE one and the same. If it were two, they'd have encountered each other, AND all of those witnesses would have seen BOTH.
There was always just one.
And RA by his own admission put himself on the bridge, after parking not-in-the-Mears-lot, after passing the juveniles, before BB, on the first platform where BB saw him once she caught up, and as Abby and Libby were coming close to the 1st-platform side of the bridge.
That's why he can't get off the bridge. He got boxed in.
By people who had no reason to lie.
The only one who gave LE false information was the one man who CAN'T BE EXCLUDED from their descriptions. The one who would have had to encounter Abby and Libby --
But said he didn't.
He's the guy.
