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.
