Police in Wisconsin have launched an urgent manhunt for a woman convicted in the notorious Slender Man stabbing case after she removed her electronic monitoring tag and escaped custody.
The Escape and Current Search
Morgan Geyser, who was committed to a mental health facility for 40 years after stabbing a classmate 19 times when she was just 12 years old, was last seen in the Kroncke Drive area of Madison at approximately 8pm on November 23, 2025. She was reportedly in the company of an adult acquaintance at the time of her disappearance.
The Madison Police Department was officially notified of her escape this morning, and her current whereabouts remain unknown. Authorities have described Geyser as "a fragile person" with a long history of delusions that make her a potential risk to others.
Background of the Case
Geyser's conviction stems from a chilling 2014 attack where she and another girl stabbed their classmate repeatedly in an attempt to "please" the fictional Slender Man character. The victim miraculously survived the brutal assault.
In a significant development earlier this year, a judge ruled in January that Geyser had maximised her treatment options at the Wisconsin mental health facility where she was being held. This decision paved the way for her transfer to a group home setting.
Public Warning and Response
Law enforcement officials are urging members of the public to exercise extreme caution and immediately contact authorities if they spot the escaped woman. Police have advised anyone who sees Geyser to call 911 immediately rather than approach her themselves.
The case has reignited concerns about public safety and the monitoring of individuals with severe mental health conditions who have committed violent crimes. Authorities continue to pursue all leads in their search for the escaped woman.
