MADISON (AP) -

Two girls accused of trying to kill their classmate as a sacrifice to horror character, Slender Man, now want separate trials.

Lawyers for Anissa Weier and Morgan Geyser filed motions last week with Waukesha County Circuit Judge Michael Bohren, arguing a joint trial could confuse jurors and both girls have made statements to investigators implicating the other.

Both girls have pleaded not guilty by reason of mental disease to attempted homicide charges in adult court. They're due to appear for a status conference on November 11.

Prosecutors say Weier and Geyser lured Payton Leutner into the woods at a Waukesha park in May 2014 and stabbed her 19 times. Leutner barely survived the attack.

All three girls were 12 years old at the time.
