Authorities in Madison, Wisconsin are searching for Morgan Geyser, the woman convicted in the infamous Slender Man stabbing case, after she cut off her GPS ankle monitor and fled her group home late Saturday night. Geyser, now 23, had recently been released under strict supervision after serving years in a mental health facility for the 2014 attack, in which she and another classmate stabbed their friend Payton Leutner 19 times to appease the fictional horror character Slender Man.

Details of the Escape
Geyser was last seen in the Kroncke Drive area of Madison at around 8 p.m. Saturday, accompanied by an adult acquaintance. Police issued a statewide alert after learning of her disappearance on Sunday morning, urging anyone who spots Geyser to call 911 immediately. The Department of Corrections said she had removed her GPS monitor—required under her conditional release—and left the group home where she was meant to stay under communal supervision until 2058.
Background and Release Conditions
Geyser’s release in July came after years in a psychiatric hospital, with her conditional release agreement stipulating ongoing supervision, reevaluations, and electronic monitoring. Placement in a group home was approved by a judge after multiple objections from the victim’s family and local officials, concerned about proximity and public safety. The plan required Geyser to remain under close watch, continue mental health treatment, and avoid contact with her victim and social media.
Ongoing Search and Community Concerns
The Slender Man stabbing case shocked the nation in 2014, and Geyser’s escape has renewed concerns about the process of transitioning mentally ill offenders back into society. Law enforcement agencies across Wisconsin are assisting in the search, and officials say the public should not approach Geyser but report sightings immediately. The victim’s family and community members are anxious as police work around the clock to locate her and ensure safety.
The investigation remains active, and Madison authorities urge the public to monitor trusted news sources and official updates for further developments.
