“Effectively misleading psychopath” In 2002 Brian David Mitchell abducted a 14-year-old teenager named Elizabeth Smart at knifepoint from her home and held her until she was rescued nine months later. For seven years following his capture, Mitchell was declared incompetent to stand trial. Finally, in 2010, a federal court judge called him an “effectively misleading psychopath” and scheduled him for trial. Mitchell was found guilty of kidnapping and sentenced to life in prison, despite his not guilty by reason of insanity plea.
