MADISON, Wis. — One of two girls convicted of stabbing a classmate to please the horror character Slender Man asked the Wisconsin Supreme Court on Friday to rule that the case should have been tried in juvenile court.
Morgan Geyser and Anisa Weier attacked their friend, Payton Leutner, in a Waukesha County park following a sleepover in 2014. Geyser stabbed Leutner 19 times, as Weier encouraged her, leaving the girl to die. All three girls were 12 at the time.
Leutner survived the attack. Geyser pleaded guilty to attempted first-degree intentional homicide in adult court in a deal with prosecutors to avoid prison. She was found not guilty by reason of mental disease or defect. Weier pleaded guilty to attempted second-degree intentional homicide in adult court. She was also found not guilty by reason of mental disease or defect.
