One of Wisconsin’s Slender Man Stabbing Perpetrators Missing from Group Home

Police issued an alert Sunday, stating Geyser was last seen with an adult acquaintance. She had been living in the community under supervision after being granted conditional release from a state mental health institute earlier this year.

Morgan Geyser, now 23, who was convicted for her role in the 2014 Slender Man stabbing, is missing after she cut off her electronic monitoring bracelet and left a group home in Madison, Wisconsin, on Saturday night.

Police issued an alert Sunday, stating Geyser was last seen with an adult acquaintance. She had been living in the community under supervision after being granted conditional release from a state mental health institute earlier this year.

The case dates back to 2014, when Geyser and her friend Anissa Weier, both 12 at the time, lured their classmate Payton Leutner to a park. Geyser stabbed the victim multiple times in a bid to please the fictional online horror character Slender Man. Leutner survived the brutal attack.

Geyser pleaded guilty to attempted first-degree intentional homicide in a 2018 deal to avoid prison and was committed to a psychiatric institution. Her attorney, Tony Cotton, has publicly urged her to turn herself in, stating, “It’s in her best interest for her to turn herself in immediately.”

Authorities are investigating a significant delay in the official response; police say they were not notified she was missing until nearly 12 hours after she left the facility.
