On November 23, 2025, Morgan Geyser, a 23-year-old woman involved in the infamous 2014 “Slender Man” stabbing, was located and taken into custody in Illinois, just one day after escaping from a Wisconsin mental health group home.
Authorities were notified of Geyser’s monitoring bracelet failing, to which it was discovered on Saturday that she had run away from the group home after destroying the GPS tracker.
Geyser’s mother had publicly expressed her worry, stating, according to ABC News: "If you see Morgan, please call the police. Morgan, if you can see this, we love you and just want to know you are safe."
The fugitive was located in Posen, Illinois around 10:34 pm on Sunday with an unidentified man.
The Posen Police Department had been informed about a group of people lingering behind a building.
When they arrived at the location, they found two individuals, a man and a woman sleeping on the sidewalk.
Authorities confirmed the woman to be Geyser, though she first provided a false name to them when confronted.
Despite countless attempts to receive her real name, Geyser spoke about “do[ing] something really bad” and told the officers to just search up her name online.
Based on NPR, her attorney had made a statement saying, “It is not in your best interest to handle this matter that way.”
Geyser was previously arrested in 2014 after stabbing her 12-year-old classmate.
It is known that Geyser and her friend Anissa Weier lured their classmate, Peyton Leutner, into a park on the day of their slumber party.
Leutner was stabbed a total of 19 times by the other two girls as a way to impress Slender Man.
The two informed investigators that their original plan was to kill Leutner in her sleep during the sleepover, but instead, they decided to execute the plan the next morning.
Thankfully, Leutner survived, although court documents stated that she was “one millimeter away from certain death.”
About three years later, Geyser admitted to the charge of attempted first-degree murder and was placed in a mental institution rather than serving jail time.
In 2018, Geyser stated to Leutner and her family, “I never meant this to happen…I hope that she is doing well,” according to CNN.
The crime garnered widespread attention at the time, as all three people involved were young children at the age of 12.
The incident sparked widespread controversy regarding the content parents were exposing their children to online.
Moreover, in January of this year, Geyser was released from Winnebago Mental Health Institute, where she had spent approximately seven years of her sentence.
Similar to Geyser, Weier was also placed in a mental hospital but was released in 2021, provided that she lives with her father and is equipped with an ankle monitor.
ABC News added that a hearing is expected to be held on Tuesday that will determine whether or not she is deported back to Wisconsin, where the original crime took place.
Geyser’s escape has revived public reflection on a crime that has never completely faded away from memory as the online community has expressed disgust and disbelief regarding the incident.
With her hearing set for Tuesday, the resurfaced case highlights how deeply the incident continues to resonate more than a decade later.
