WAUKESHA, Wis.– Morgan Geyser, convicted in the “Slender Man” stabbing case, appeared by video in court Thursday to once again file for conditional release.
Geyser was committed to the Winnebago Mental Health Institute after she stabbed her classmate at a sleepover over the fictional online horror character “Slender Man” when she was 12.
She was granted conditional release in January of last year after three failed attempts.
However, she escaped her group home in November of 2025 and fled across state lines to Illinois, where she was captured. Her conditional release was revoked in February in 2026.
Her attorney, Anthony Cotton, filed this latest petition for conditional release on August 25, arguing that the conditions of the group home and influence from an older adult caused Geyser to make an impulsive decision.
“The ​only ​way ​you ​can ​institutionalize ​a ​person ​is ​if ​they’re ​dangerous,” says Cotton. “It’s ​a ​terrible ​place. Bad ​conditions, ​obviously, ​poor ​oversight. ​Morgan ​felt ​like ​she ​didn’t ​have ​any ​similarly ​aged ​peers ​that ​were ​there. She ​made a ​half ​hearted ​attempt ​to ​get ​out ​of ​there, ​but ​she ​didn’t ​do ​something ​violent.”
The court has ordered new doctor’s evaluations that are due in November. Cotton claims Geyser is not dangerous, but the prosecution says they have some concerns.
“The ​state ​has ​some ​concerns, ​given ​the ​decision ​making ​process ​that ​Ms. ​Geyser ​seemed ​to ​have ​gone ​through ​blatantly ​violating ​the ​rules, ​cutting ​the ​bracelet ​off ​and ​leaving ​the ​placement ​that ​she ​was ​in,” says Waukesha DA Abbey Nickolie. “I’m ​very, ​very ​interested ​to ​see ​how ​stable ​these ​doctors ​believe ​that ​she ​is ​now.”
Geyser is back in court on November 9.
