BM's good friend said that if BM wanted to make a body disappear so it could never be found, he could do it. I'll take BM's good friend's impressions about that.
IMO, there is NO WAY BM would have paid an unsavory type to get rid of SM's body. Why? Three reasons:
- It was something he likely believed he'd be better at (just as his friend believed he'd be good at it);
- Doing it himself meant he wouldn't have a potential witness out there who, next time they got themselves in serious trouble with the law, could trade info about BM to make things easier on themselves; and
- BM is too cheap to pay some drug addict, meth head, or former convict good money for anything other than to save himself hard labor (and even then, he is himself being paid).
ETA: I think there may even be a 4th reason: I think BM is proud he was so good at making SM disappear and throwing around smoke after such that LE has not found her and his family believes his claims he had nothing to do with it.
