The linked article details the Klosterman murder-suicide. The situation shows the height of emotions that can be reached when people separate. There truly is a thin line between love and hate.
The article also hits very close to home. My first divorce client was murdered by her estranged husband. Their adult son later killed him the day before his father's murder trial was to begin. She had a Protective Order, but as I always tell my clients, you are responsible for your own safety. A piece of paper cannot stop a bullet.
The absolute need for early alternate dispute resolution and the use of mental health services cannot be demonstrated any more clearly.
