A Waukesha County judge has granted a petition to revoke the conditional release of a woman known for the Slender Man stabbing after she fled from a Madison group home last month.
Morgan Geyser was in sixth grade when, in 2014, she stabbed her classmate in order to please the fictional horror character known as Slender Man. She was committed to a state mental health facility after she pleaded guilty to attempted first degree intentional homicide.
Geyser was granted conditional release over the summer and had been living in a group home. But she removed her ankle monitoring bracelet the night of Nov. 22 and fled from the group home in Madison. She was arrested at a truck stop in a Chicago suburb one day later and was later extradited back to Wisconsin.

The Wisconsin Department of Health Services, or DHS, filed a petition to revoke her conditional release shortly after the incident. On Tuesday, Waukesha County Circuit Court Judge Scott Wagner granted that petition.
The decision came after Geyser’s attorney Anthony Cotton sent a letter to Wagner saying Geyser would not contest the revocation, according to an Associated Press report.
Geyser appeared on Zoom during a short hearing Tuesday morning. Wagner said that Geyser had, “freely, intelligently and voluntarily made the decision not to contest the DHS petition for revocation of conditional release.”
Wagner then said the petition to revoke her conditional release was “meritorious, uncontested, and it is granted.”
Geyser was ordered back into DHS custody. Cotton did not immediately respond to a reporter’s request for comment for this story.
Jonathan LaVoy, a defense attorney and partner with Kim & LaVoy Attorneys at Law in Milwaukee, said Geyser’s escape from the group home was “very provable by the state.”
“This wasn’t just a minor violation that might have been, you know, coming back late from a movie or something like that,” LaVoy said. “This was a severe violation.”
On Dec. 10, a Waukesha County spokesperson said Geyser was no longer in custody at the Waukesha County Jail. Her “placement and transport” is under seal, according to the spokesperson.
Geyser had been at the Winnebago Mental Health Institute since 2018. She filed a petition of release in 2024. A final plan and placement for her release to a group home was signed on Sept. 17.
