IMO, it is quite possible that BM has known that SM has been dead, and the futility of finding her body, almost from the beginning, and he knows who killed her. he has been going thru the steps of dealing with this death in the public eye, while also trying to be patient with LE, as they build a solid case.
Heck, we’re impatient, I would be beside myself.
He’s also dealing with all sorts of personal attacks, and some are even indirectly smearing his wife’s memory.
yet he really can’t defend himself without accusing someone. I found a real interesting bit of info in one of AMs recent interviews.
Something BM said.
My speculation, based on my lifetime experiences...
