It does all read like fantasy fiction, for sure, but if the crime scene description is accurate, the killer(s) did some super bizarre things: posing and seemingly redressing bodies, painting a tree with victim blood, placing sticks on and around the bodies, putting two bras on one girl, etc. We don't have to interpret that as Odinism, but we've long known the CS was "odd," thanks to RI, and now we might better understand why.
This goes far beyond killing because some girls laughed at him, or he wanted to SA them, imo. It's weird. Maybe eating paperwork weird. Idk. No matter what we believe as individuals, and no matter the spin either the prosecutor or defense puts on the crime scene, it was the killer(s) who left it that way, and it's not normal. Jmo.
