Rumors were flying last January that the next season of American Horror Story would be about the character, although the teasers FX has been releasing in anticipation of the September premiere haven’t revealed much. In a case similar to the Slenderman attack, two 16-year-old West Virginia girls in July 2012 lured a third friend, 16-year-old Skylar Neese, into the woods, stabbed her and left her to die. The Slender Man mythos has attracted a larger pop culture interest since the attempted murder brought it out of the shadows of the Internet. Two court-appointed doctors will examine Geyser, who was diagnosed with schizophrenia and oppositional defiant disorder, before the judge makes his ruling in the case. They were both 12 at the time of the attempted murder and are both being tried as adults, despite protests from their lawyers, Geyser’s mother, and assorted criminal-justice advocates.

Weier has also pled not guilty, but without the added claim of mental illness. Their victim survived the stabbing and crawled to safety she returned to school three months later.

Geyser and schoolmate Anissa Weier are charged with attacking and stabbing a schoolmate 19 times in order to curry favor with Slender Man, an extremely creepy but entirely fictional character that’s the subject of fan fiction and art among younger denizens of the Internet.
