Very interesting...and it did seem that Christina's mom was much more forgiving of her boyfriend's failure to report her missing than she was with the idea that the walker failed to walk her to her car. In my opinion, she has seemed more perturbed with the walker than anyone throughout this whole ordeal. I wonder if in her heart (and off the record) that's who she suspects?
I haven't spoken to the family directly. However the searchers I've talked to tend to lean this way.
Then again that is natural considering he was the last with her. What a mess that would be for him if he just went home for the night.
