WAUKESHA — The second of two girls accused of trying to kill their classmate to please horror character Slender Man has pleaded not guilty by reason of mental disease or defect.
Anissa Weier, 14, entered her plea in Waukesha County court on Friday. Judge Michael Bohren appointed two doctors to examine her and turn in a report on her mental status by Oct. 6.
Weier and her friend, Morgan Geyser, have been charged with attempted first-degree intentional homicide in connection with the May 2014 attack on Payton Leutner.
Prosecutors allege Weier and Geyser lured Leutner into a wooded Waukesha park and stabbed her multiple times. All three girls were 12 years old at the time.
Geyser entered her plea of not guilty by reason of mental disease or defect last month.
Anyone 10 or older charged with attempted first-degree intentional homicide is automatically considered an adult under state law. The girls’ attorneys had been seeking to move their cases into juvenile court, where they could be incarcerated for three years and then supervised under age 18. A state appeals court, however, ruled last month that both girls’ cases should remain in adult court, saying the crime was planned and violent.
That leaves the state Supreme Court as the girls’ last hope of being moved into juvenile court, but Geyer's attorney Tony Cotton said Friday he won’t ask the high court to take Geyser’s case because it doesn’t present a novel question of law.
According to court documents, the girls invited Leutner to a birthday sleepover in May 2014. The next day they lured Leutner into some woods at a Waukesha park, stabbed her repeatedly and then fled. Leutner suffered 19 stab wounds, including one that doctors said narrowly missed a major artery near her heart. Leutner crawled to a road where a bicyclist found her.
Police captured Geyser and the other girl on Waukesha’s outskirts later that day. They told investigators they had hoped killing Leutner would gain them favor with Slender Man, a demon-like character featured in online horror stories.
They said they were planning to walk 300 miles to the Nicolet National Forest, where they hoped to live as Slender Man’s servants in his mansion.
Leutner recovered from her wounds and returned to school that fall.
