Im not usually a Dr Phil fan but I have to say he did a good job with this interview. George and Cindy know that people want an explanation from them about their daughter and the events. I think they did try to explain themselves. I dont think Cindy was making excuses or lying. She was trying to explain her thought process at the time. Of course she didnt want to believe that her daughter could do this. The brain tumor, hormones and seizures are not Cindys excuse as much as her wondering if there could be some explanation for this. It will take a long time for them to process the fact that their daughter killed their granddaughter., Who wants to think, as a parent, that the child you raised could do this. that's what I got out of the interview. George and Cindy are not perfect, they have made mistakes. Whenever there is a tragedy some people tend to rewrite history. Cindy may be rewriting history here a bit for her own benefit, but I dont think its to be devious. I think its so she can digest it.
Time will tell if CA's excuses pan out regarding her daughter - unless there is some medical miracle wouldn't at least one or more of the felons problematic health problems resurface in the event they are real?
