If that actually is the case, it would be incredibly alarming for all. This would be the act of someone so wily, scheming and manipulative that he could literally get away with murder. And it would fit with what might emerge as a pattern. If RA reported to LE he had the phone on the trail but in fact did not, it's the same wily type of behavior, he "slips through the cracks" later and does not even become a suspect. It would fit with his surge of panic over the "Odinite guards," and personally, I wouldn't even have made the connection in his situation to the patches. He did, though, even though he's supposed to be so mentally distracted while incarcerated. And it might even fit weirdly with the phone with his image recovered at the scene. He seems perhaps like he wants to be exposed, he wants to be seen-- but only to a point. In the end, he still wants to get away with murder, MOO. And tragically, it might also line up with the CS generally, and its ritualistic qualities. It's been suggested that was done to misdirect LE.
So maybe it was. RA went through a pretty intense program of study to become a pharmacist, it's a STEM focused program and he'd have to be highly intelligent to do it. One would also have to be highly intelligent to have gotten so close to escaping punishment for heinous murders. All MOO, but if he's convicted, I hope they start looking at other murders with similarly distinctive CSs in the area because a pattern like that starts looking like an SK. The "involvement of others" might be pretty indirect in nature in that he uses them to find victims.
