I can't see any part of definition of any kind necessary to really determining his age at all.
Before, most saw a grizzled older man with facial hair of some sort, hair color, etc. Now people can suddenly see a "baby face".
But you could be right that she just happened to catch him in the background as she recorded Abby.
However, LE has been pretty clear in their praise of Libby's heroism in intentionally and surreptitiously capturing this man on a recording.
It's blurry, IMO, because of the distance.
Also he may indeed have been trying to conceal his age with his clothes.
I agree with you that it’s impossible to tell age based on the distance in the video, but I feel the person on the video appears to be much younger than that of the first sketch for sure. It’s hard to make out his face, but I can tell he’s got a clean face.
I was thinking that the heroism part related to what occurs after he meets them at the end of the bridge, but thinking further, it is possible she was trying to record in a manner that didn’t give away the fact she had a phone, and hence, asked Abby to look like she was doing something in his direction so she could get a view. LE would know this for sure as I bet they were talking about it before BG approached.
You can actually see something in the front of BG that appears to be focused, prob Abby’s coat. We will probably never see the original video. Although I think if it had been meant to capture him, we would have gotten a longer video than a 2 second video clip that is not even focused. I think the angle of the camera shifted and BG was no longer in view, that’s why the video is so short and there isn’t more footage. I think he was still far away enough that I don’t think they had seen him as a threat, yet, either.
She probably placed the phone on her pocket, etc and kept it there while they went down hill. There is definitely more audio, but I don’t think LE would want to release because it may damage the case and we probably do not want to hear it anyway.
As I said earlier, I’m was not convinced that they got that video from the phone, I think the phone was destroyed. As per a previous post, this is what appears to have happened and the video/audio was retrieved from cloud.
One other thing I struggled with was the hat, which many have posted different looking ones here, including hunting, bomber hats, etc and I could never make it out to be a hat - I feel he is not wearing a hat, but a wig. It appears to be light color and appears too thick. I think that was part of his outfit and he probably took it off after the murders.
All imo...
