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.
The 14-year-old girl changed her plea Friday in Waukesha County Circuit Court from a previous not-guilty plea. Judge Michael Bohren, who is presiding.
The girls were identified in open court and the criminal complaint as Morgan E. Geyser and Anissa E. Weier, who were 12 years old at the time of the incident in 2014.
Anissa Weier entered a plea of not guilty by reason of mental disease or defect to the attempted homicide charge. If convicted, each girl would face up to 40 years in prison and 20 years on extended supervision.
Both defendants in Waukesha's Slender Man stabbing case have now entered insanity pleas.
The Associated Press initially chose not to name the girls in case they were tried in juvenile court, where proceedings are secret and penalties aren't almost as harsh.
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.
A judge ordered doctors to review the girl's mental health, and to return a report by October 6. She and another teen girl are being charged as adults for the alleged May 2014 attack on a classmate.
The 14-year-old girl and Geyser were captured on the outskirts of Waukesha. Juvenile proceedings are secret and The Associated Press hasn't named the girls in case they're waived back to that level. Weier and Geyser had planned the attack for months and claimed it was to "impress" Slender Man, a fictional internet character that lurks in the woods.
After the incident, the victim, also 12, crawled to a nearby road in Waukesha, Wisconsin, where a passing bicyclist found her the next morning.
Defense attorneys have requested juries from outside of Waukesha County due to media attention.
