In May 2014, Anissa Weier and Morgan Geyser (then 12 years old) allegedly stabbed a classmate 19 times, leaving her in the woods near their hometown of Waukesha, Wisconsin. The victim, Payton Leutner, survived and returned to school the next year, but the local community was rocked by the attack.
Waukesha County Circuit Judge Michael Bohren decided last year that both girls would be tried as adults, allowing for the full severity of a first-degree murder charge. This was understandably controversial due to the girls' delusional belief in Slender Man, along with Geyser's assertions that she could perform Vulcan mind melds, and the fact that both would otherwise be considered children.
Judge Bohren has appointed two doctors to evaluate Morgan Geyser, who entered her Not Guilty plea on Friday. According to the Wisconsin Journal, experts have already testified in court that she "suffers from schizophrenia and oppositional defiant disorder and maintains relationships with imaginary characters."
If Geyser is judged to be mentally fit to stand trial, she faces a sentence of up to 40 years in prison.
