After a full day of deliberations, which lasted until late Friday night, a jury in Waukesha County found that Anissa Weier was mentally ill when she and a friend attacked another girl, leaving her to die in the woods. All three girls were 12 years old at the time of the stabbing, three years ago. The victim was able to find help, and survived.
Weier and Morgan Geyser said they planned the stabbing in order to please the internet horror character Slender Man. Attorneys for Weier argued that she believed Slender Man would harm her family if she did not attack her classmate.
