Who would have ever imagined that Odinism would become part of the Delphi murder investigation (I do know it was rumored)? Regardless of what each of us believes on if it's related, the fact of the matter is that LE did have to investigate this angle. That's shocking to me. That they even had to talk to a professor of Norse mythology is just...baffling. That they had to do that makes me more curious if the FBI BAU did, in fact, determine that the killer had Norse beliefs. Somebody, somewhere, had to see something in the stick placement to even get the wheels rolling on this, IMO.
I'm not seeing anything in what the professor, TC, or anyone (other than the D's theory) said that suggests ritual sacrifice, though. And if the sticks really were placed in a rune-like array, like a fanboy Odinist wannabe might do (like what the professor said), that still doesn't make me automatically think ritual sacrifice. It makes me think a)the killer fashioned the sticks in a certain manner, maybe in a Norse-like way, or maybe someway we can't even understand, and that was part of a signature based on his deeper beliefs (unrelated to the killings), or b)he was trying to stage the scene to look like something it wasn't.
I tend more towards the signature idea, seeing as there are a few sources cited by the D to suggest Norse/runes/etc, and RI's "odd" comment. At the April 2019 PC, I always remember DC telling the killer that he thinks he still had a little bit of conscience left. I have always wondered if that might have been because the killer tried to cover up the bodies. So yes, maybe the sticks were just an attempt at that, but if it was done with some kind of pattern, whether rune or otherwise, perhaps that pattern was one of the signatures? IDK...just thinking.
