In every press photo of this girl, there is no smile.  Look at the eyes - there is something going on behind those eyes, or there is not.  She is a psychopath.  She has no empathy for her victim, although she has probably been coached to express some level of responsibility and sorrow for those whose lives she has impacted.  I'm convinced, that if you are born that way, that is who you are.  A leopard cannot change it's spots.
