Officer: Slender Man stabbing victim says defendant obsessed

Officer: Slender Man stabbing victim says defendant obsessed

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.

Her friend, Morgan Geyser, who helped with the stabbing has pleaded not guilty by reason of mental disease. But she also pleaded not guilty due to mental illness or defect, setting up the trial on her mental status.

Weier made her first appearance in front of a jury of eight men and eight women on Tuesday in Waukesha County, Wisconsin, where her attorney, Joseph Smith, told jurors in court that her parent's divorce caused a depressed that descended her into madness as she latched onto Geyser. He asked jurors to consider why if the girls were so afraid of Slender Man they waited so long to attack Leutner. Jurors will determine whether she was mentally ill at the time of the stabbing.

"I know now it's just teenagers who really like scaring people and making them believe false things", Weier told Waukesha Detective Michelle Trussoni.

Three psychologists testified that she suffered a shared delusion that she and Geyser had to kill Leutner to become Slenderman's servants and prevent the character from killing their families.

Ms McMahon claimed Weier and Geyser had become obsessed with Slender Man, developing a condition called shared delusional disorder.

Weier's attorney Maura McMahon said justice would be achieved by placing her in a secure mental hospital, where she belongs.

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.

Melissa Westendorf was appointed by a judge to evaluate one of the girls, Anissa Weier, now 15, after her insanity plea.

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

A lawyer for Anissa Weier said that her mind was "broken" when the attack happened, the Associated Press reports.

A young schoolgirl has helped her friend stab her own classmate for as many as 19 times, a development which has caused quite stir.

Geyser's trial is due to begin October 9. Her legal team successfully argued that she truly thought she was serving as a proxy for a supernatural creature called the "Slender Man".

Both Weier and Geyser were originally charged with being a party to attempted first-degree intentional homicide.

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