In all fairness to Parker, he certainly knew JS had a problem. I think because of being away from home a lot, he didn't realize the full scope of her illness. I also believe he didn't fully understand it. And he didn't really effectively stem his daughter's hate speech, which was so devastating to JS. He seemed to believe Julie was choosing to be ill; even though he mentioned in his email to her doc that her recent downturn followed a med change.
He was certainly very concerned in the months prior to the murder -- repeated emails to her doctor. It was a poor choice to leave her alone with the children. Perhaps the abnormal had come to seem normal. Perhaps he just let his job take precedence -- one time too many.
BBM:
PS said she was "broken" when he married her. He knew of her condition for 20 years. He criticizes family members for
their ignorance in his emails. (read the emails)
How can anyone NOT know or understand their significant other's MI when they've been with them for over 20 years? That's like not understanding your SO's diabetes, cancer, MS, etc.
Not once, in the paperwork from LE or Child Protective services on the abuse, is Mental Illness or alcohol abuse mentioned. WHY NOT?
Children usually mimic the behavior of one or both parents. Was the children's attitude towards JS was a direct result of observing interactions between JS and PS?
Scientists agree there is a genetic pre-disposition for bipolar. Was Calyx's behavior indicative of BP coming to the surface?
I believe PS and the children were embarrassed and ashamed of JS. They "shamed" her. She was "broken". (WTH, who says their wife is "BROKEN"?) How can a person with BP live in that environment?
JS could not live up to the standards her husband and children expected of her. Her own brother added to the fire in his email to her, probably not having a clue. She had failed. If she only killed herself, it would be another "embarrassment" the family would have to carry. She didn't want to add that to what she already perceived as a huge burden on her children or husband.
By killing her children, herself, and maybe even PS, no one would be ashamed or embarrassed anymore. It's all about "appearances".
In her mentally ill "reality", it made total sense.
