Slender Man case: Motion filed to stop Wisconsin judge's order to release Morgan Geyser, convicted in stabbing of Payton Leutner

MADISON, Wis. (WLS) — A woman from Wisconsin, who is currently serving time for her involvement in the 2014 Slender Man stabbing case, is facing uncertainty regarding her release from a mental health facility following recent developments.

The video in the player above is from a previous report.

Morgan Geyser, the individual in question, was scheduled for a hearing to discuss a potential release plan, but this hearing has now been called off. This decision comes in light of new allegations made against Geyser by the treatment facility where she is currently housed. These allegations involve Geyser allegedly sending violent artwork to a man.

Her lawyer denies that she did anything inappropriate.

Earlier this year, Waukesha County Circuit Judge Michael Bohren instructed the Wisconsin Department of Health Services to devise a supervised release plan for Geyser within a specified timeframe of 60 days.

A new hearing to consider whether Geyser’s release should be revoked is set for next week.

Geyser — now 22 — was 12 when she and a classmate lured their friend into the woods in Waukesha, Wisconsin, and stabbed her 19 times to please the online fictional character Slender Man, according to authorities, in a case that continues to generate national headlines.

The victim, Payton Leutner, suffered life-threatening injuries but ultimately survived. Geyser and her co-assailant, Anissa Weier, were charged in adult court with first-degree attempted intentional homicide.

Geyser was convicted of the charges but found not guilty by reason of mental disease or defect, and was sentenced to up to 40 years in a psychiatric institution.

Weier was found not guilty by mental disease or defect after pleading guilty to a lesser charge, and was sentenced to up to 25 years in a psychiatric institution. In 2021, at the age of 19, Weier was granted supervised release.

Three psychologists had testified last month that Geyser is also mentally ready for supervised release.
