I am way behind and still somewhere in the middle of the previous thread. But I still wanted to post this because people don't seem to know what to do with the sketch and the video. This is all my personal opinion.
LE isn't asking the public to look for anything strange in the video, like if he has a disability (they even said at the PC that people have to remember that he is walking over this bridge that is in very bad shape) or if and what might be in his jacket, etc. They know all that already because I'm sure they had all kinds of specialists watch the video to determine all those things (they might not know exactly what is hidden in his jacket but I also don't think that's all that important). For example if he had a disability, they would have told the public. Probably 2 years ago (we only had stills, they had the entire video right from the beginning).
Same goes for the voice - they are not asking the public for any accent he might have, speech impediment, etc. They probably have more audio and they know all this already.
And the sketch - they don't want the public to look for weird things like lazy eyes or some kind of illness they think they can see in the sketch.
They also don't want any tips about the above mentioned things - if a thousand people send them "tips" about illnesses or disabilities they think they can see, you just give them a lot of work and distract them from the work they actually have to do.
What they are looking for is people who KNOW the perp. Wth the sketch, no idea how similar it actually looks to the real person, but especially now with the video plus the voice from the video, somebody out there KNOWS who this is. If you know a person really well, family that you spend a lot of time with, co-worker that you work with every day, good friends, best friends, a neighbor that you know well, from the short video and even before, the last 2 years just from the voice and the stills, you recognize the person.
So knowing this (or at least suspecting this), it's really creepy to me that someone out there knows who this is. Probably even since the stills were released plus the "down the hill" recording. Probably more than one person knows who this is. And that's the tip that LE is waiting for. Hard to believe that those people are just looking the other way. They have to take a deep breath and call police, he might do it again and I just know I wouldn't want that on my conscience.
All MOO.
