Hmm, maybe you are correct.. have we been assuming all this time that the 'family member' that SB was last seen by, at her home, at 12:30am on November 27th, was her estranged husband, without it ever having been confirmed at any time? I suppose it was an easy stretch, considering that the two still reportedly shared the same home. But it is certainly possible that it wasn't the estranged husband afterall. I can't help assuming it was the husband for the following reasons:
i)they reportedly still lived in the same home
ii)she had presumably just arrived home from out of town a couple of hours before she was last 'seen'
iii)it was a weekday work night, and with JB reportedly having a regular weekday job, most need to get to bed in order to function at work
iv)imho, they are stating 'family member' instead of 'estranged husband' because they may not want to lead people to unfairly think the wrong thing
v)someone would need to be home to feed the reported dog, if indeed the dog is still residing in SB's home, but we really dont' know that either
However.. now that we are aware of this couple's alternate lifestyle, in addition to their estrangement, it is quite possible that JB wasn't even home at all during those days from Wednesday night through Monday. But if that is the case, then who would it have been in the family that last saw her at her home at midnight on a weeknight? Why wouldn't LE or family want to say who it was? And why isn't that person, whomever it is, saying what the circumstances were at the time, and what any of SB's stated plans may have been, and which frame of mind SB may have been in.
