I always believed that true conspiracy is very hard to organize, because where can one find a large group of smart and disciplined people? When it comes to LE, between “malicious intent” “covering up” and “incompetence”, I would err on the side of incompetence. It took me a while to decide in this case, but when I heard Doug Carter, commenting on the audio recording, “it was the voice of the Devil”, it dawned on me, “incompetence, not malice.” Next time, they collected DNA from 300+ people to no avail. I thought, “does he even believe DNA exists?” Sometimes I wish ISP were covering up for someone “big”, one could sleuth the person, and it would be movie-like. But on their podcast, only Robert Ives sounded coherently. Having listened to the audio multiple times, as well as the recordings of RA’s voice, I am sure that both are human with a “hollow” note in them. But in such surreal atmosphere, it is easy for the defense to see the runes, and the odinites. Essentially, the same.
ETA: the link. In this article. DC literally said it was the voice of devil coming through the killer. BTW, DC has hollow voice, too, so I understand the comments about "generic Midwestern Man voice", "generic clothes", etc. The BG was no odinite, no devil, likely a regular Midwestern man, and the rest around the case stems from the same human trait, gullibility.
