More than a decade after she helped carry out the Slender Man stabbing, Morgan Geyser is being sent back to a secure psychiatric hospital. A Wisconsin judge on Tuesday revoked the 23-year-old's conditional release and ordered her returned to the state's Winnebago Mental Health Institute following her November escape from a supervised group home, Fox News reports.

Geyser had been living at the YoYo Quality Care facility in Madison, Wisconsin under court-ordered conditions when she cut off her GPS monitor and left on Nov. 22; staff did not report her missing until early Nov. 23. She was arrested later that day at an Illinois truck stop with 43-year-old Chad Mecca and has been held in the Waukesha County Jail since her extradition from Illinois.

Judge K. Scott Wagner granted a request from the state Department of Health Services to end Geyser's release privileges. Her attorney, Anthony Cotton, argued in a letter to the court that Geyser should be in a treatment setting, not jail, noting she "has no new criminal charges in Waukesha County" and was previously found not guilty by reason of mental disease or defect in the underlying case. Wagner granted Geyser conditional release in January after nearly eight years at Winnebago. She told the court through Cotton last week that she would not fight revocation of her conditional release, the AP reports.

Geyser and friend Anissa Weier were both 12 in 2014 when they lured classmate Payton Leutner, also 12, to a park in Waukesha and stabbed her 19 times in an attack they later said was meant to appease the internet-born horror figure Slender Man. Leutner survived. In 2017, both teens pleaded guilty to being a party to attempted intentional homicide but were found not guilty by reason of mental disease. Geyser was ordered to serve 40 years at a mental health facility. Weier, who was ordered to serve 25 years, was granted conditional release in 2021.
