Whatever happened that night, and I believe it was pre-planned and brutal, you have to consider the size, weight, and strength difference. And then you add in that Shanann was 15 weeks pregnant, didn't feel well, and was very tired, all of which were exacerbated by the flight delay and wanting to be home. Finally, also add in surprise, as in; surprise attack! Shanann had reached, what she no doubt felt, was the safety and comfort of her home, regardless of issues to be dealt with. Her guard would be down and she would be very vulnerable. I have no doubt CW planned that and reveled in it and the nightmare began! Monday we'll know much more (gulp, shudder).
