On Thursday, her attorney said she would plead not guilty by reason of mental disease or defect in the Slender Man case.  Two girls accused of trying to kill a classmate to please horror character Slender Man want jurors from outside their home county to decide their trials. A letter the other girl's defense attorneys submitted to the court seeks outside jurors as well. Investigators say Geyser and Anissa Weier, who were 12 at the time of the 2014 attack, plotted for months before luring the victim, who also was 12, into some woods and repeatedly stabbing her. They remain charged as adults with attempted first-degree intentional homicide, after efforts to have their cases transferred to juvenile court were denied. Someone found not guilty by reason of mental disease or defect is typically committed to a state mental hospital for treatment.
– Both girls in Wisconsin's disturbing "Slender Man" case will now be pleading not guilty by reason of insanity. Attorneys for 14-year-old Anissa Weier signaled this week that they want to change her plea in the attempted murder case from not guilty to "NGI," meaning that she's likely to be committed to a state mental hospital for treatment if found not guilty, reports the Milwaukee Journal Sentinel reports. Co-accused Morgan Geyser, who is also 14, has been diagnosed with early onset schizophrenia and has already entered an NGI plea. Both girls were 12 years old in 2014 when they allegedly stabbed a 12-year-old classmate 19 times and left her for dead in what they told investigators was an attempt to please the online horror character "Slender Man." In July, an appeals court ruled that they should be tried as adults for the attempted killing. WISN reports that lawyers for both girls are seeking to have the case heard by jurors from outside Waukesha County, where the attack took place, because of heavy media coverage.
