This is very interesting. Thanks so much for posting.
CW stated he told SW that he wanted a marital separation. Perhaps SW was the one who wanted a marital separation?
I looked at SW's facebook last night. There are no posts after the later part of June, and my thoughts are those have been taken down. Why?
In earlier posts, SW seemed excited about the trip to NC and stated she was preparing meals for CW during her absence. I'm beginning to think something happened when she was in NC. I'm not sure if it was planned for him to join them in NC for the last week, or if this was an impromptu thing.
IIRC, SW noticed he was distant when they were in San Diego. She then immediately left for the trip to NC, but that was pre-planned.
Pure speculation on my behalf, but perhaps SW discovered CW's affair (and/or other secrets) while she was in NC and told him she wanted a separation and the reason he went down was to try to talk her out of it?
If SW was moving forward with plans to separate, if CW did not want a separation, this might explain a lot.
Last night I read a little on filicide, when a parent murders their child or children. Revenge against a spouse is given as one of the reasons this type of murder occurs.
There are elements of the family annihilator with this crime with respect to CW. If the little girls were murdered before SW got home, my thoughts are there may also be elements of filicide as well.
All JMO.
