It struck me that since he kept repeating the thing about Missy being "passionate about helping others with fitness" over and over and that was all he really had to say about her that it was a very practiced and rehearsed speech. If I had a wife and she was the world's best athlete, or whatever, that would be the last thing I would think about or mention, and he kept repeating it in almost the exact same sentences like it was scripted. And then he said I'm very sorry for the people that really cared about her. Wtf? But police say no one on that list is a suspect and they have a bunch of new suspects or POI's so who knows.
To me:
LE said they have a bunch of new suspects
+ the planned media statement by BB speaking of the good she did for others well-being,
+ BB's mom's letters being directed to someone specific (I think Fem, but it works for M, too)
= a killer related to MB's fitness classes or that sphere
Could be a colleague, a relative of a colleague, a disgruntled husband of one of MB's clients who doesn't want the positive changes he's seeing in their spouse (people get angry at friends, doctors, therapists, trainers, DV professionals, etc. who are helping their spouse in some way and are afraid that the positive changes will prompt their spouse to leave the marriage)
The last idea may be reaching, but it happens.
I just want to add that jealousy can be a motive caused
even though there is no affair, but the spouse is paranoid and assumes there is no matter the reassurance or logic that there is
no affair.
I'm no beauty by far, but I've had
more than my fair share of wives "make a friendly visit". One of my doctors wives, three bosses' wives and two of my customer's wives making it a point to visit me and tell me how wonderful their marriages are and how close they are and warn me off, sometimes not so subtly. One kept calling me at work to tell me - I told my boss/her husband and I quit after two visits and two calls - I saw the pattern. I can't help what their husband's tell them, but I can assure everyone that there have been no hints of romance, sex, whatever on my part. :shrug:
Insecure women can get desperate and vicious and all without cause or need.
