Eric, at the time sludge insisted she was not of sound mind and would probably be found unfit to plead. In reality when she was assessed she was found fit for trial. The opinion was that her mental health had appeared to have seriously deteriorated since her arrest but that at the time of the incident she was of sound enough mind to know what she was doing and was responsible for her actions.
I recall thinking when I read it that the deterioration in her mental health seemed a little too convenient to me, but that's just the cynic in me coming out.
