Doctors Judge Girl's Sanity in 'Slender Man' Stabbing Morgan Geyser isn't legally competent to stand trial, they say By Neal Colgrass, Newser Staff Posted Jul 2, 2014 7:00 PM CDT 16 comments Comments A drawing of Slender Man. (Wikimedia Commons) (Newser) – The prospect of an insanity plea loomed over a hearing in Wisconsin today for two girls accused in the "Slender Man" stabbing of a classmate, the Milwaukee Journal Sentinel reports. Two doctors (one for the defense, one prosecution) said that one of the 12-year-old girls, Morgan Geyser, isn't legally competent to stand trial. The judge then approved a request for another examination, of Geyser's mental health at the time of the attack—a possible basis for a not-guilty plea—and a competency hearing on August 1 to consider the issue, the AP reports. Geyser's attorney objected, saying his client hasn't entered a plea and there's no probable cause to go to trial yet. But if the judge deems Geyser mentally incompetent, she can't be tried, convicted, or sentenced in Wisconsin (unless she regains competence). Insanity is hardly a surprise issue in the case, considering that prosecutors say the girls attacked their classmate to gain approval from a mythical Internet figure known as "Slender Man." The victim, meanwhile, is recovering at home from 19 stab wounds. "She continues to amaze us in her ability to persevere and move forward—taking one day at a time," her family said in a statement.
