In a dramatic turn of events, the case of the Slender Man stabbing has taken a new twist: the known assailant, Morgan Geyser, has gone missing after cutting off her court-mandated monitoring bracelet and leaving her supervised group home.
Opening Update
Morgan Geyser, the woman linked to the 2014 Slender Man stabbing, was reported missing after she removed her Department of Corrections monitoring device and departed a group home in Madison, Wisconsin. She was last seen late Saturday evening in the Kroncke Drive area, accompanied by an adult acquaintance. Authorities posted an alert early Sunday morning and urged anyone with information to contact 911.
What Happened: Key Facts
- On Saturday night, November 22, 2025, Geyser removed a tracking device worn as a condition of her supervised release.
- Police in Madison confirmed that she walked away from the group home facility shortly after the device was removed.
- Her last known location: around 8:00 p.m., in the Kroncke Dr. vicinity of Madison.
- Her attorney publicly requested she surrender, warning that continuing on the run would be in her worst interest.
- The public remains on alert; law enforcement continues to investigate community tips and sightings.
Background: The 2014 Attack
Back in May 2014, in the Milwaukee-area suburb of Waukesha, then-12-year-olds Morgan Geyser and her friend Anissa Weier lured their classmate Payton Leutner to a wooded area after a sleep-over. There, Geyser stabbed Leutner 19 times while Weier encouraged the attack. Leutner survived.
The attack shocked the nation in part due to the bizarre motive: the attackers claimed they were acting to “please” the fictional internet character Slender Man and believed it would protect their families.
Both girls were tried as adults. Geyser later pleaded guilty to attempted first-degree intentional homicide and was committed to a state psychiatric facility rather than a traditional prison. Weier pleaded guilty to a lesser charge, also entered a mental health institution, and was released under supervision in 2021.
In 2025, after more than seven years of treatment at the Winnebago Mental Health Institute, Geyser was approved for conditional release to a supervised group home.
Supervised Release and Conditions
- In early 2025, a county judge approved Geyser’s conditional release following expert testimony that she had made considerable progress in treatment and was ready for a less restrictive environment.
- One of the key conditions: wear a GPS-monitoring bracelet tied to the Department of Corrections.
- She was placed in a group home under supervision, subject to rules and monitoring designed to protect the community.
- Records show that the release plan and the exact location of the facility were sealed or kept confidential for safety and privacy reasons.
- Despite oversight, Geyser’s decision to remove her device and depart the facility challenges the structure and effectiveness of the supervision plan.
Latest Developments & Law Enforcement Response
- The alert issued by the Madison Police Department came early Sunday. They released a still image from recent security footage and stated that Geyser’s whereabouts were unknown at that time.
- Police asked the public not to approach her but to immediately call 911 if she is spotted.
- Her attorney emphasized the urgency of her voluntary surrender and noted he lacked information on her current location or any accomplices.
- Authorities are treating this disappearance as a critical public safety matter given the history and context of her original conviction and release conditions.
- At the same time, the family of Payton Leutner has been notified of this development and remains in close contact with law enforcement about their safety.
Timeline of Key Events

Implications and Concerns
The disappearance of Morgan Geyser under supervised release raises significant concerns on multiple fronts:
Public safety:
This episode underscores the challenge of supervising individuals who committed violent offenses when placed in less restrictive environments. Even with monitoring devices, the risk remains that those individuals may abscond and pose potential risks to the community.
Mental health and rehabilitation:
Geyser’s release from a secure psychiatric hospital to a group home was based on findings that she had made sufficient progress. Her escape now puts that decision and the processes behind conditional release under scrutiny. It raises questions about how well the transition from institution to community is managed, especially for cases tied to extreme and rare motives.
Legal and correctional oversight:
The failure of the electronic monitoring device to prevent her departure may prompt a review of monitoring technology, alarm responses, staffing at group homes, and inter-agency coordination (psychiatric, corrections, and community supervision). It also may raise questions about resource allocation for supervision in such high-profile cases.
Victim impact:
For Payton Leutner and her family, this development is a distressing reminder of the attack and introduces new anxiety. The expectation had been that Geyser’s supervised release would allow a measure of closure. Now, the unknown whereabouts of the person who nearly killed Leutner reopens emotional wounds and may impact her sense of security.
What to Watch Next
In the coming days, several key developments will be significant:
- Updates from Madison Police on any credible tips, confirmed sightings, or arrests related to Geyser’s whereabouts.
- Any new statements from Geyser’s attorney regarding what led to her decision to remove the monitoring bracelet and leave the home.
- Possible reopening of hearings or motions by the state to recapture jurisdiction over Geyser and to potentially modify release conditions or reinstate more restrictive custody.
- Community reaction in Madison and Waukesha County about oversight of individuals released from psychiatric institutions after violent crimes.
- Further commentary from victim-advocate groups or legal analysts about how to balance rehabilitation with public safety in cases involving serious juvenile offenders.
This story remains very much active and ongoing. The disappearance of Morgan Geyser brings into focus both a chilling legacy of the 2014 Slender Man stabbing and new realities about supervision and rehabilitation in the U.S. justice system.
