Weier and Morgan Geyer baited colleague Payton Leutner into the forested areas at a recreation center in Waukesha, a Milwaukee suburb in 2014.
According to the plea agreement, she has to spend ten years in jail if she judged normal and if she judged mentally ill then she has to spend at least three years in a mental hospital.
Maura McMahon, Weier's attorney, said she trusted the case uncovered that kids might be taking care of mental issues lost on grown-ups who have turned out to be excessively occupied with their own particular lives, making it impossible to focus and assets proliferate to help them. Her trial is set to begin on October 9. The two young ladies ended up plainly fixated on Slender Man and Weier trusted the creature could read her brain and would execute her family or her on the off chance that she discussed him, McMahon guaranteed.
A shared delusion and an interest in the paranormal led two girls to stab another 12-year-old girl in a Wisconsin park as a tribute to the fictional horror character Slender Man, a psychologist testified Wednesday. But she claimed she was mentally ill during the attack and not responsible for her actions, in a bid to be sent to a mental institution rather than prison.
Weier's attorneys argue she was delusional at the time of the stabbing, which happened when all three girls were 12.
"I know now it's just teenagers who really like scaring people and making them believe false things", Weier told Waukesha Detective Michelle Trussoni.More news: Niall Horan announces tour after releasing new single

He played segments of Weier's police interrogation in which she described a plot to kill Payton in order to become a proxy of Slender Man. The girls were allegedly trying to please the fictional internet bogeyman Slenderman.
A second psychologist has testified about the delusional mental state of a girl who's admitted to helping stab a classmate almost to death in a Wisconsin park in 2014.
Van Rybroek examined Weier previous year.
"There's no walking away for Anissa, no loophole", McMahon said. That delusion was so strong, Van Rybroek said, that Weier "couldn't stop herself at the moment it mattered most", and helped stab Leutner even though she knew it was wrong. Co-defendant Morgan Geyser is scheduled to go on trial next month.
Both Weier and Geyser were originally charged with being a party to attempted first-degree intentional homicide.
Weier, now 15, pleaded guilty to attempted second-degree intentional homicide in a deal with prosecutors in August.
