I couldn't respond on the last thread before it closed, but I know
@CuriousCricket wondered if RH was cutting corners because of his "hobbies." Have wondered on this as well. Definitely recognizing the "cutting corners" is possible. I've been back and forth on the "cutting corners" idea, but I
don't think RH's little mistakes with the burlap and belts are necessarily because of cutting corners. I also don't think his letting that house fall to pieces was just "not having the money," either. I think RH harbored serious hatred towards one or both parents and it's reflected in all the "TLC" he gave the home. Meaning even if he had a ready flow of cash, he'd still like to see it in shambles. Pure speculation, though.
I think the hairs are normal transfer, and he recognized that such a transfer was a risk for him, but one he was willing to accept so long as his disposal methods would promise concealment for an extended period of time.
As for the monogrammed belt, don't think this was any accident or even just convenience of a kind. I think there was something special to him about that certain victim. There's some weird reason why he left that belt. I'd compare that belt to the phone calls he made to MB's family. There's some trigger with that particular victim in RH's head that prompted those calls, and with MBB, there was something at work in RH's mind-- particular to his experiences with that victim-- that prompted the leaving of the belt as well. (Believe phone calls also made to friend of MBB.) Both of these "gestures," the phone calls to victims' family/friends and the belt, carry tremendous risk for him, but I don't think he's able to restrain himself. Also think Peaches was special to him in some way and that is why her remains have been found in so many locations, and why her remains mark the parameters of the graveyard. 100% agreed, though, that RH is a "problem-solver" and some of his handiwork would reflect that.
As for the idea of a third SK, seeing that mentioned a lot, I sure hope not. But you never know. Have wondered for years if there was any kind of association between RH and Bittolff. Hoping we get some answers about what they were searching for out there recently. The idea of another SK can't be ruled out, adding another level to this horror show, three of these sick freaks at work in the same relatively small area of territory.
