Even though Payton - who was left for dead in the Waukesha, Wisconsin, park - was stabbed in her abdomen, chest, and a millimeter away from a major artery, she somehow managed to crawl to a bike path where she was found by a cyclist the next morning. Really, they had been planning to kill Payton for months as a sacrifice to Slender Man, a fictional, tall and faceless horror character who lives in the woods. Morgan and Anissa had invited their 6th grade classmate Payton over for a sleepover in May 2014 supposedly to celebrate Morgan's 12th birthday. They are currently being tried as adults and could face up to 65 years in prison, ABC News reports. That means that if the two 14-year-olds are found not guilty of first degree attempted homicide - their victim, then-12-year-old victim Payton Leutner, miraculously survived the brutal attack - by reason of mental disease or defect, they will be committed to a state mental institution. Anissa Weier later entered the same plea. One of the girls, Morgan Geyser and who Newser reports has been diagnosed with early onset schizophrenia, had previously entered the plea. Both of the girls who lured their classmate into the Wisconsin woods and stabbed her 19 times to please the fictional character "Slender Man" entered a plea of not guilty by "reason of mental disease or defect," also known as NGI, the Milwaukee Journal Sentinel reports.
