A startling development emerged in the high-profile Slender Man stabbing case — the convicted attacker, Morgan Geyser, is now missing after cutting off her court-mandated monitoring bracelet and leaving a group home under supervision.
Latest confirmed details
- Geyser, now 22 years old, was last seen around 8 p.m. Saturday, Nov. 22, 2025, in Madison, Wisconsin, with an adult acquaintance.
- Authorities say she intentionally removed her Department of Corrections electronic monitoring device before walking away from the residential facility.
- A public alert was issued on Sunday morning after officials notified the police of her disappearance.
- Geyser had been living in a confidential group home this year after conditional release from the psychiatric hospital where she’d been committed.
- Her attorney publicly urged her to surrender, emphasizing that the situation is not in her best interest to continue on the run.
- Geyser’s co-defendant in the 2014 attack, Anissa Weier, was released under supervision in 2021.
Background of the 2014 attack
In May 2014 in suburban Waukesha, Wisconsin, then-12-year-old Morgan Geyser and Anissa Weier lured a classmate, Payton Leutner, to the woods after a sleepover. Geyser stabbed the victim 19 times while Weier encouraged the attack, saying they aimed to “please” the fictional horror figure Slender Man. Leutner survived the life-threatening injuries.
Geyser and Weier were tried as adults. Both were found not guilty by reason of mental disease or defect and committed to long-term psychiatric institutions. Geyser’s stay lasted about seven years before conditional release in early 2025.

What this means
Geyser’s disappearance under supervision raises serious concerns about community safety, oversight of psychiatric releases, and the handling of violent juvenile offenders. The fact that she walked away while wearing a monitoring device suggests significant planning or lapse in supervision protocols.
For the victim and her family, this development likely revives trauma and anxiety as they face uncertainty once again. Authorities continue to urge anyone with information on Geyser’s whereabouts to contact 911 immediately.
Considerations and broader context
- The case remains one of the most widely discussed examples of internet-influenced violence in the U.S., due to the central role the Slender Man myth played in motivating the assault.
- This incident prompts ongoing debates about the balance between public safety and mental health rehabilitation when serious offenses are involved.
- Monitoring technologies and group-home placements for individuals with violent histories are under fresh scrutiny given the apparent escape.
What to watch next
- An official update from the Madison Police Department on Geyser’s status and any leads in her location.
- Statements from her defense team regarding her next legal step or surrender.
- Reactions from the victim’s family and victim-advocate organizations.
