"2) it was (IIRC) going to be the last class at the church," Don't recall seeing anything that would indicate MB was moving the class. I'd like to see a link if that's the case. And if true, one would assume that she would still be having a 5 am class somewhere... and it would have been likely to be somewhere outside just like before, and she would go to that location at 4:15 just like at Creekside, so if perp was targeting Missy, wouldn't he have the same opportunity at a new location that he had at the old one?
Yes, I think it is just a rumor based on the 9:00 class which apparently was moving locations from the community center or to the community center. I will see if I can find the post in which someone linked MB's post about it.
