WAUKESHA, Wis. -

An attorney for one of two Wisconsin girls accused of trying to kill a classmate to please horror character Slender Man says she's given up trying to move the girl's case to juvenile court.

During a court hearing Friday, 14-year-old Anissa Weier pleaded not guilty by reason of mental disease or defect for the May 2014 attack.

Her attorney, Maura McMahon, said after the hearing that she was no longer trying to get the case moved to juvenile court, a fight that had been ongoing since Weier and her friend, Morgan Geyser, were taken into custody.

Geyser's attorney said last month he'd given up on moving her case.

The Associated Press had chosen not to name the girls in the event their cases shifted to juvenile court, where proceedings are secret.

Earlier Friday, Weier entered a not guilty by reason of mental disease or defect plea in Waukesha County court. 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 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 also has entered a plea of not guilty by reason of mental disease or defect.
