Morgan Geyser, one of the "Slender Man stabbers" who hacked and ambushed a classmate when she was 12 years old, was captured after cutting off her ankle monitor and escaping from the Wisconsin group home where she was living, the Madison Police Department confirmed on the city's official website Sunday (November 23) night.
"On 11/23/2025 at approximately 10:34pm, The Madison Police Department received confirmation that Morgan Geyser was taken into custody in the state of Illinois. There is no longer a need to search for Morgan Geyser at this time,," the department said.
Geyser, now 23, was reported to have led police on a manhunt after escaping Saturday (November 22) night.
"Officers are searching for a woman who cut off her Department of Corrections monitoring bracelet and left a group home Saturday night," the department said. "Morgan Geyser was last seen in the area of Kroncke Dr. around 8 p.m. with an adult acquaintance. Her whereabouts are unknown as of Sunday morning. The Madison Police Department was notified of her disappearance Sunday morning. A recent image of Geyser, captured on security video from this past month, is attached below. If you see her, please call 911."
Geyser and her friend, Anissa Weier, lured a fellow student into a Waukesha, Wisconsin, park and stabbed her 19 times during the incident in 2014, which they said they carried out in an effort to impress "Slender Man," a supernatural character who was the subject of internet forums, video games and later a 2018 horror movie. The victim miraculously survived by crawling her way to safety until making contact with a passing bicyclist.
Geyser, then 15, pleaded guilty to attempted first-degree murder as part of a plea deal that led to her being placed in a mental institution rather than serving jail time. Waukesha County Circuit Court Judge Michael Bohren ordered Geyser be released from the Winnebago Mental Health Institute and sent to a group home after three psychologists testified that she was prepared for supervised release, which would include her wearing a Department of Corrections monitoring bracelet.
