there is obviously much we will have to await trial to learn. I think it is possible that heather and sm were back in touch, maybe even seeing each other again, and that is what tm found out and could not tolerate. Their fb posts (the m's) in nov. And dec. Seem all about redemption...hum making up to her, kissy face, etc. Which was probably after tm discovered the affair the first time. Sm swore no more, and then tm caught him again sometime near or on december 17/18th. Heather may have told her friends she was done with sm, if they disapproved of him, or maybe she was but was tempted back. We don't know. But clearly, imo, something happened to make heather a threat to tm again, when she thought she had "handled" the problem. This time, she would make sure. I still am not convinced sm wanted this outcome at all, but it does not excuse him, morally or legally.
The only thing left sm can do to show any heart, morality or even a shred of humanity is to confess and bring le to heather. And then take the consequences. Sadly, affairs are all too common, but they should never end in murder. It is unfathomable. Much worse than diane zamora and david graham, due to sm's age and that he is a parent, imo.
