I've not posted on this case yet, and I can't say that I am fully aware of all the details (seriously, ya'll are out of control on the postings here! WOW!).
A coworker was giving me a brief outline a few weeks ago, and I've popped in to keep up as much as I can.
He (my coworker) outlined his theory for me based on the killer being female. He believed there was infidelity involved, and that it was likely on MB's part. Reason being that someone having an affair with BB would be aware that he was married (probably), and wouldn't be so rageful. That this has the signs of being a woman scorned, and that it was perhaps MB's lovers wife or girlfriend.
I went and watched the full 'interview' that BB did the day after Missy was killed, and while a lot of the things he said, and the way he said them seemed off to me (I'm accusing him of nothing!*), the one thing that jumped out to me and will not leave my mind is the remark about 10 months. Along the lines of 'In the past ten months, she had been texting me each morning once I got to work to tell me she loved me and hoped I had a good day'.
This has probably already been discussed to death and I missed it, so I apologize if I am rehashing old stuff.
But my thought at the time, and my thought more so now, is that
she got caught having a fling of some sort, 10 months ago. And the decision was made that they would work past it, and the texts were one of the ways she let him know she was 'in'. For the long haul. Because who, one day after their wife was murdered, has such a random passing of time readily available like that? Someone who had some life altering stuff go down 10 months ago.
This is all apropos of nothing, I suppose, it rules no one out, and I am just babbling away. But it drives me bonkers and I had to vent it out.
*I am not of the opinion that BB killed, or hired someone to kill Missy. That doesn't change the strangeness of what he said and how he said it, one day after she was killed. I think this is because of the strain in the relationship, the (possible) knowledge of infidelity - he was holding back information and it showed in his words and demeanor. That's all.
