The legal representative for the woman involved in the infamous 2014 Slender Man stabbing case is petitioning for her return to a mental health facility following her recent escape from a Wisconsin group home. The attorney is advocating against her current confinement in jail.

Morgan Geyser, now 23 years old, was detained at the Waukesha County Jail after being extradited from Illinois, as reported by FOX 11. Her arrest transpired in Posen, Illinois, subsequent to her escape from a group home in Madison the previous month.

Despite her current incarceration, Geyser’s attorney is steadfast in his assertion that she should be placed in a mental health facility instead of a jail cell. The attorney, Anthony Cotton, emphasized this stance in a letter addressed to Waukesha County Judge K. Scott Wagner. Cotton highlighted that Geyser has no new criminal charges in Waukesha County and was previously found not guilty by reason of mental disease or defect in her original court proceedings.

Geyser’s apprehension took place in Posen, Illinois, on Sunday, November 23, 2025, as confirmed by the Posen Police Department.

Geyser allegedly fled the YoYo Quality Care group home on the evening of Nov. 22, but she was not reported missing by officials until the early morning hours of Nov. 23. She and 43-year-old Chad Mecca were found by authorities at an Illinois truck stop later that day. 

Geyser is set to remain in custody until Dec. 22, when Wisconsin Department of Health Services officials are expected to discuss a formal revocation of her conditional release, according to the Milwaukee Journal Sentinel. 

Geyser was granted conditional release in January and placed in a group home in September, after spending nearly eight years at the Winnebago Mental Health Institute.

Additionally, authorities have not yet revealed what – if any – new charges Geyser may be facing following her escape. Officials previously indicated that she may face felony criminal charges since she allegedly cut off her electronic tracking device as she was leaving the group home, the Sentinel reported. 

The Dane County District Attorney’s Office did not immediately respond to Fox News Digital’s request for comment regarding any potential criminal charges against Geyser. 

In 2014, Geyser and her friend, Anissa Weier, were having a sleepover with classmate Payton Leutner when the two girls lured Leutner to a local park. Geyser stabbed Leutner 19 times while Weier egged her on, nearly taking her life. All three girls were 12 at the time of the attack.

Geyser and Weier later admitted to investigators that they tried to kill Leutner to appease fictional horror character Slender Man, and were fearful of him hurting their own families if they did not carry out the attack.

Both girls were found guilty by reason of mental defect or disease in 2017 and sentenced to mental confinement, with Weier ordered to serve 25 years and Geyser for 40 years.
