Agree.
MOO BG is stepping right to start cutting Abby off from joining Libby off
the bridge.
MOO
Mannerisms, I think there were any.
I looked again as suggested. Then I
saw this, he has a couple of head movements which seem to reveal a manner if moving.
He looks ahead and down -
all normal things to do on the bridge, but done in his own way.
MOO to me his manner of movement is very quick but somehow soft and
slidy or slinky.
I think you would have to know him to recognize the mannerisms in real life. I don't know that I would notice that in someone just walking down the street. I am sure LE is hoping family and friends will now study the video more after recognizing the sketch and have to admit to themselves what their relative/friend did and get him to turn himself in.
