Attorney: Slender Man attacker descended into 'madness'

A 15-year-old Wisconsin teenager pleaded guilty to stabbed her classmate in order to please a fictional horror character - Slender Man.

Three years back in 2014, Anissa Weier and Morgan Geyer tried to attack classmate Payton Leutner, they were into the woods in a Waukesha park in Milwaukee suburb.

McMahon urged the jury to send her to a mental hospital rather than convict her as a criminal which would have seen her serve over 10 years in prison. A jury trial on her case, which began Monday, was set to determine whether Weier was mentally ill when she committed the crime.

Weier, now 15, pleaded guilty in August to being a party to attempted second-degree intentional homicide. Weier and Geyser were arrested later that day and said they were walking to meet Slender Man in a northern Wisconsin forest.

"Life is better for youngsters when grown-ups around them are in correspondence with each other", she said.

All three girls were 12.

"She will have an uphill road", McMahon said.

Perhaps it is no wonder that Anissa Weier has been found not guilty Friday. She said Weier felt she "needed that time so that she could learn to live in a non-jail environment and that she knew she would need help getting her head straight to do that". "Anissa told [court-appointed psychologist Dr. Melissa Westendorf] that she didn't want Morgan to feel insane, so she said yeah", Waukesha County Deputy District Attorney Ted Szczupakiewicz said during closing arguments. McMahon said before the inconsistent verdict came in Weier "was shaking so hard, she was shaking me". Both sides asked for a directed verdict - letting the judge decide - but Judge Michael Bohren ruled the case will be decided by the jury.

Although Weier did not physically stab Leutner, in her mind she knew it had to be done, Smith told jurors. At one point before the attack, prosecutors claim Weier unleashed Geyser by saying "go berserk", according to the Journal Sentinel.

But he never saw anything to suggest she needed mental health care.

Mr Van Rybroek's expert testimony matched that of another psychologist who said Weier and Geyser had a shared delusion about Slender Man.

The Slender Man is a fictional supernatural character. He asked jurors to consider why if the girls were so afraid of Slender Man they waited so long to attack Leutner. The teen moved from apparent complete belief in Slender Man to a realization that she had been duped.
