Accomplices
There is little doubt in my mind that the husband bears some responsibility for this awful tragedy. He strikes me as a control freak and he is probably guilty of mental abuse that may have driven her over the edge.
He will likely be lionized by NOW for his understanding and his culpability may never be exposed. If he is what I believe he is, he should be punished.
Regardless of sanity issues, there are things so terrible that when done, a normal existence in no longer possible. The lobotomy is an expression of my rage and is as close to CP as I will venture.
