A Wisconsin woman who admitted to helping stab her former classmate to please the fictional character Slender Man will be freed from a mental health institution, a judge ruled Friday.

Anissa Weier, 19, has been at Winnebago Mental Health Institute since December 2017 after pleading guilty to attempted second-degree intentional homicide. She was initially sentenced to 25 years at the hospital but will now be subject to constant GPS monitoring and will receive outpatient psychiatric treatment under the conditions of her release, according to the Associated Press.
