I've been lurking and following this thread since #1 and diligently reading but I've never posted before so please bear with me. First of all, I've seen some very good questions that I too would like answered and some very plausible theories about what could've happened. I would like to say I have formulated my own theory but there are just too many missing puzzle pieces for me to say with confidence what I believe could have happened.
In light of the recently posted article written by Chris Graves about BJM's account of what happened, I actually find myself with even MORE questions than before. It may that I've just been thinking way too hard about this case over the past couple of weeks but I find it very odd that we've heard no confirmed mention of two other adults being with BJM until this article. Why would that not have been brought up before if there was nothing to it? Why not report that BJM and two other individuals were present upon the discovery of the bodies? I would have at least thought LM would've said it, since he was a well of information (however accurate/inaccurate he was) in his interviews at first. One could speculate he didn't know, but he knew enough about what BJM saw that I would think he would know that his daughter wasn't alone.
I don't know what relevance it has; maybe none at all. I just think it's weird. I also wonder how DR/BJM's brother knew to go to DR's unless BJM called him at some point between finding the four and police arriving and told him to check on her. I may have missed that explanation. It's just not all adding up, IMO.
I don't believe that BJM murdered her family and ex-in-laws. I do think the recounts of what happened that we have seen from family members are just different enough that it warrants wonder. I think that it's very likely she and DS know more than they've let on, and maybe LE knows what that is and is keeping it tightly locked from the public.
All of this is just MOO. Anyway, I hope to sleuth more about this with you all as things keep popping up.
