This doesn't answer your question, but it includes info that I don't recall that D.C. has ever come outright and said before.
I thought I would put it here as I know that not everybody is listening to these podcasts.
In the link below from the podcast,
SCENE OF THE CRIME – A NEW DIRECTION at around the 41 minute mark, this direct quote by Doug Carter from the April 22nd presser is mentioned.
"The result of the new information and intelligence over time leads us to believe the sketch which you will see shortly is the person responsible for the murders of these two little girls."
At the 42 minute mark, Kelsi discusses the decision to switch to the new sketch with Doug Carter.
Delphi: A New Direction from Scene of the Crime: Delphi
DC: Remember a sketch is just a visual, it’s not a photograph. It’s a visual of what somebody might have seen. So that’s all I’ll say about the sketch.
KG: In 2019 a new composite sketch of the suspect was created that looks a lot different to many people than the original sketch. How and why was the new sketch created and why might it appear much different?
DC: Yeah, well…I can’t talk about that in detail, but I will simply say that the investigation has evolved….and there are things we know that we can’t explain. And I know there was a lot of anxiety about that, and even there was even some confusion and some blame and some criticism of us. Uh…that criticism needs to come to me and not to anybody else because I absolutely supported that change.
All JMO - But I now have two scenarios in mind:
1-two different people were there that day that were dressed very similarly and both were seen by different witnesses. LE has decided that one person/sketch has now become a 'secondary' because they know that the other person is the one who committed the actual crime. The person in the 'secondary' sketch may even be the witness mentioned in the April 22nd press release;
We have a witness. You made mistakes."
ISP release new information on Delphi murder suspect
2-the same person was seen by multiple people but he disguised himself by hiding his face (with a scarf or even a mask?) and is, in fact, both sketches. He was seen pre-disguise and post-disguise. Thus, DC saying that he "May end up looking like both sketches."
