A judge is hearing testimony about the mental health of one of two 12-year-old Wisconsin girls accused of stabbing a classmate to please a fictional character.
The girl's attorney has said he believes the girl is mentally ill and wants the case moved from adult court to juvenile court.
Dr. Brooke Lundbohm of the Wisconsin Forensic Unit testified Friday that she interviewed the girl in June.
The girl claims to see and hear things that others cannot - including unicorns, Slender Man and Voldemort, an antagonist in the Harry Potter series.
The court-appointed psychologist says the girl laughed "almost hysterically" during their session.
Court documents say the girls plotted for months to kill their former friend to win favor with Slender Man, a character in online horror stories.
