My 1st post hear in a long time, but I have alot of random thoughts and all IMO:
1. In re to PE: he doesn't fit my suspect since the release of the YBG sketch in April, but since the following article does mention that LE requested his DNA,
Delphi murder investigators request dead rape suspect's DNA, and a tip was sent in about him, I'm beginning to think maybe PE or a close relative of his was interviewed before April 2019. But then I also think that LE would of collected DNA at that time.
2. Also, ever since the YBG sketch was released in April, I have believed that the witness (woman?) who came forward months later because she was scared (I know this was in a news article, but no I don't have a link for it), was never really on the trails that day, but does 100% know who BG is and gave a description of him based on what her male relative/friend (BG) told her he looked like that day so that is how the OBG sketch came about. Also, I believe the vehicle parked at the old welfare building is known to LE and sometime in between Feb.-April 2019, LE came to realize that the vehicle belongs to the female "fake" witness or her close relative/friend and she was not in the vehicle that day, but YBG was. And yes she is/was scared of BG, but only of him getting arrested and sent to prison, so she is covering for him. Also, she might of told LE she parked that vehicle in a location different than at the welfare building and LE knows that location is a lie. Or possibly she even told LE that the vehicle in the welfare parking lot was not being used at all that day.
3. Whoever said they had a dream about an arrest in Delphi and now LE have mentioned PE, I really think dreams like that do happen. When Jayme Closs rescued herself, I did have a dream several days before that she was found and that really did come true!
ETA-hope all of my ramblings make sense. If not, I apologize!
