Still catching up on the thread since it was closed when I tried to post last night. But here are my thoughts after the presser.
I'm still of the belief that MB was targeted and her murder was a very personal crime of passion. I believe that LE has much more information than what they are sharing with the public. I also believe that they have a suspect in their sights and an arrest will happen. IMOO the presser was to update/perhaps appease the public that after a month without an arrest, the investigation is still ongoing.
In the meantime, there's been a lot of speculation on the suspect/motive/gender. What about the timing/location? There was only a small window of opportunity for the murder to take place before people started showing up for the class. So it had to be well planned. Why was it so important that it be carried out in the rain on that specific day at that specific location? I recall reading that kids were out of school that week, this was her first class since her return from Austin, last or next to last class at this location. Did she already have a new location for her next class, or was it TBD?
