A 12-year-old girl accused of stabbing a Wisconsin classmate to please a fictional online character has been ruled mentally unfit to stand trial.

Morgan Geyser and classmate Anissa Weier, 12, were charged with attempted murder after the victim was stabbed 19 times on 31 May.

The attack, which the victim survived, was allegedly in "dedication" to Slenderman, a character on the website Creepypasta.
