Geyser told the judge through her attorney, Tony Cotton, last week that she would not fight revocation. Wagner then approved the request during a short hearing.

Geyser and her friend Anissa Weier lured their classmate, Payton Leutner, to a Waukesha park in 2014. Geyser stabbed Leutner 19 times while Weier cheered her on. A passing bicyclist discovered Leutner, who barely survived. All three girls were 12 years old at the time.

Geyser and Weier later told investigators they attacked Leutner in hopes of impressing Slender Man enough that he would make them his servants and wouldn’t hurt their families.

Slender Man is a fictional character that was created online by Eric Knudsen in 2009 as a mysterious figure photo-edited into everyday images of children at play. He grew into a popular boogeyman, appearing in video games, online stories and a 2018 movie.

Both girls were eventually committed to the Winnebago Mental Health Institute — Geyser for 40 years and Weier for 25 years.

Weier earned conditional release in 2021. Wagner granted Geyser conditional release this past September despite warnings from state Department of Health Services officials that she couldn’t be trusted. Geyser was placed in a Madison group home.

Authorities say that on November 22, she cut off her GPS monitor and fled the state with a 43-year-old companion. Police arrested both of them the next day at a truck stop outside Chicago, about 274 kilometers south of Madison.

Geyser’s companion told a local TV station that they became friends at church and had been seeing each other daily for the last month. Geyser allegedly decided to escape because she was afraid the group home would no longer allow them to see each other.
