That is what you consider to be the motivation behind the murder? I think you just proved the case for the defense.
A sane and deliberate requires a motive, the one you gave is about the weakest I have ever heard. If the woman wanted help, why did she stop taking the medication?
I thought it was reported that her doctor took her off the psychotic medication two weeks before the murders.
She had no motive; she was crazy. And, for some reason, they stop taking their medicine. Had a relative, manic-depressive, that for years refused to take his lithium. He'd forget. Even though he knew, while his was on lithium, that he needed to take it. ???
