Illinois authorities have arrested Morgan Geyser, the woman at the center of the infamous 2014 “Slender Man” stabbing, after she escaped a supervised group home in Wisconsin over the weekend. Police say the 23-year-old removed her monitoring bracelet on Saturday night before traveling roughly 170 miles south, where she was located at a truck stop in Posen, Illinois.
According to a statement from local officials, officers responded to reports of a man and woman loitering and found the pair asleep on a sidewalk. When questioned, Geyser refused to give her real name—eventually telling officers they could “just Google” her because she had “done something really bad.” The man accompanying her, identified by police as 42 years old, was charged with trespassing and obstructing identification before being released, as first reported by CBS News.
Geyser’s escape has reignited public attention on a case that once shocked the United States. At age 12, she and her friend Anissa Weier attacked their classmate, Payton Leutner, stabbing her 19 times in a suburban Wisconsin park. Prosecutors said the pair believed they were acting under the influence of Slender Man, a horror-fiction figure that originated on the forum Something Awful and spread through online “creepypasta” stories. The character—depicted as a faceless, elongated figure—became a viral symbol of internet-born folklore.
Geyser was later sentenced to 40 years in a psychiatric facility and granted conditional release in July to a supervised home in Madison. Her co-defendant, Weier, who was sentenced to 25 years in a psychiatric institution, was conditionally released in 2021.
Experts say the incident underscores ongoing challenges with managing violent offenders whose crimes occurred during childhood. “Cases like this sit at the intersection of mental health, juvenile justice, and the real impact of online narratives,” said a Wisconsin-based criminal psychologist familiar with high-profile juvenile cases.
For Wisconsin residents, the news has revived painful memories. Some community members took to social media expressing concern about public safety, while others emphasized the complexity of reintegration for individuals with severe mental-health histories.
The victim, Leutner, survived the attack and has since maintained a private life. Her survival remains one of the most widely reported elements of the case, covered extensively by outlets including BBC.
Geyser is expected to be returned to Wisconsin, where authorities will determine the future of her supervision and legal status.
