1 of 2 girls accused in Slender Man stabbing to be sentenced

WAUKESHA, Wis. (AP) — One of two Wisconsin girls accused of stabbing a classmate to win favor with a horror character named Slender Man is about to learn how long she will spend in a mental health facility.

Anissa Weier (ah-NEE'-sah WY'-ur) pleaded guilty in August to being a party to attempted second-degree intentional homicide, but claimed she wasn't responsible for her actions because she was mentally ill. In September, a jury agreed.

A Waukesha County Circuit Court judge is expected Thursday to send the 16-year-old to a facility for at least three years.

Payton Leutner (LYT'-ner) survived 19 stab wounds in a Waukesha park in 2014. Leutner, Weier and the other attacker, Morgan Geyser (GY'-zer), were 12 years old at the time.
