Although her defence mentioned her mental state at the time of the murder, I did not find any sources claiming she underwent any psychological assessments, which I do find quite shocking and disappointing. I don’t doubt there is some sort of mental illness or trauma present here.
I also read she threatened to kill her own parents weeks prior to the wedding. I would not be surprised if there was some sexual abuse present in her childhood. I definitely think there is more to the story and her lack of providing a motive is to prevent certain things from being exposed. Thanks for reading, Carolyne!
