Slender Man Stabbing Attacker Morgan Geyser Cuts Monitoring Device and Disappears from Supervised Wisconsin Residential Facility
Authorities in Wisconsin have issued a public alert and initiated an intensive search for Morgan Geyser, the woman convicted in the high-profile 2014 “Slender Man” stabbing case, following her unauthorized departure from a supervised residential facility. Ms. Geyser, now 23 years old, reportedly removed her court-ordered Department of Corrections monitoring bracelet before leaving the group home in the Madison area late Saturday evening, November 22, 2025. Madison police confirmed receiving notification of her disappearance on Sunday morning and subsequently released a recent security image of the missing woman, urging the public to contact emergency services immediately with any information regarding her whereabouts. At the time she left the facility, she was reportedly seen with an adult acquaintance, though the identity and status of this individual remain unconfirmed by officials.
Morgan Geyser was conditionally released earlier this year from the Winnebago Mental Health Institute, a psychiatric facility where she had spent several years following her plea of guilty to attempted first-degree intentional homicide in 2017 but was found not guilty by reason of mental disease or defect. This arrangement allowed her to avoid a lengthy prison sentence by committing her to the mental health institution for a period of up to forty years. The judge presiding over her case granted the conditional release to a supervised setting after mental health experts testified that she had made significant and demonstrable progress in treating the mental illness, namely schizophrenia, that had contributed to the shocking 2014 attack.
The original crime involved Geyser and her friend, Anissa Weier, both twelve years old at the time, luring their classmate, Payton Leutner, into a wooded area of a Waukesha park and stabbing her multiple times in an effort to appease the fictional online horror character known as Slender Man. The victim barely survived the brutal attack, which drew international attention to the influence of online horror culture on vulnerable children. Following the recent confirmed breach of her court-mandated supervision, Ms. Geyser’s attorney publicly urged her to turn herself in immediately, emphasizing that cooperating with law enforcement is firmly in her best long-term interest. The current priority for law enforcement agencies is the swift and safe apprehension of the missing woman.
