Slender Man stabbing: Anissa Weier found mentally ill

A Waukesha County jury will begin deliberations on Friday morning to decide whether Anissa Weier was mentally ill when she and Morgan Geyser stabbed a classmate, Payton Leutner, 19 times on Memorial Day 2014 in order to win the favor of the fictional character Slender Man.

Melissa Westendorf testified at Anissa Weier's mental capacity trial in Wisconsin that she believes Weier suffered from a shared delusional disorder when she and Morgan Geyser tried to kill Payton Leutner in 2014.

Geyser pleaded not guilty because of mental disease to being a party to first-degree attempted intentional homicide.

Jurors are having to decide whether Weier was mentally ill at the time of the attack at a park in the city of Waukesha, when all three girls were aged 12.

Her lawyers have claimed Weier was suffering from a mental illness at the time and "lost touch with reality".

Weier and co-defendant Morgan Geyser (GY'-zur) were accused of luring classmate Payton Leutner (LYT'-nur) to a wooded area in a suburban Milwaukee park and then attacking her.

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. Weier's attorneys are trying to convince jurors she was mentally ill during the attack and should be committed to an institution rather than prison.

Weier told investigators she and Geyser believed they had to kill Leutner or else Slender Man would kill them and their families. Leutner managed to crawl to the side of a road where a cyclist found her. Westendorf was appointed by a judge to evaluate Weier, now 15, after her plea.

Prosecutors say a Wisconsin girl accused of helping stab a classmate to appease online horror character Slender Man participated in a cold and calculated attack.

He said: "They have really good accelerators but not very good brakes".

"He could easily kill my whole family in three seconds", she told the detective.

"In my opinion, she was a normal child", he said. The state said Weier complied with the Slender Man story and the murder plot for the sake of her friendship with the co-defendant.

Geyser, who did the stabbing, will go on trial next month. That caused her to share in Geyser's belief that Slender Man was real.

Weier, now 15, pleaded guilty in August to being a party to attempted second-degree intentional homicide.
