I just saw the beginning of the video to which you most likely refer. I didn't see this video. But you are correct. My apologies.
The video I saw was dated January 13, 2020. Two YouTube guys were there. I found it very interesting, and I liked the way the guys were treated by (the Sheriff's Dept?). Like I said, at the time, I didn't realize the Delphi murders were in Indiana, and I learned a lot from the video. Up until then, I was only vaguely aware of what had happened, so the video brought out a lot I didn't know.
Those of you who have been on this from the beginning are much more aware of things than so many other people, like me. But maybe the videos will bring you fresh insight or maybe more substantial information on the girls' killer, and between everyone you'll get the case solved.
I have discovered over time that sometimes you can be so close to something and not see 'the obvious', because it is indeed 'hiding in plain sight' OR the direction you are looking in isn't quite where the object is. It's just out there in your peripheral vision
Have you ever seen two pictures where they show you two that are the same except one has a mistake and ask where the mistake is? Sometimes it's glaring at you, but you just can't see it. This may be a case where the killer is right in plain sight but he's someone people overlook because he is trusted. Trusted to the point that no one suspects him. Or it's so far from the personality he presents that people can't see him as a killer.
As far as the composite goes. Remember Ted Kaczynski? Look at the composite for him, and then the actual man when he's arrested. I just don't see Ted Kaczynski in that composite. He looks younger there. Could the killer have changed his appearance since the murders? Grew a mustache, a beard, shaved his head, grew his hair long, changed his hair color, changed his hair style, started/stopped wearing a hat, a hoodie. Wears glasses, changed his glasses, got contact lenses. Anything to change his appearance. Or, could he be someone so nondescript, people don't even see him. He's almost invisible to people.
I read constantly. But maybe some of you have seen the movies about The Bourne Identity, where Jason Bourne's description isn't usually the same twice. His hair is brown, dark brown, blonde, light brown, reddish, black. His eye color changes because he wore different color contacts. He's a chameleon. Maybe your killer is like that.
The other thing is, they say, when someone does something like this, there is something in that person's behavior that's like a red flag. They do change, somehow. Become more unkempt, change in their personality. There was a guy ages ago, he killed a teenage girl, and I think a young girl. They did that profile thing, and I don't remember what led to him being caught, but, the changes in his personality/behavior were there all along, but I think he was from another state. No one put him together with the crime.
Maybe you already knew all this, if so, excuse me for running on.
I hope this killer is on the verge of being caught. Best Wishes.
