MADISON, Wis. – The Wisconsin woman who admitted that she almost stabbed a classmate to death In 2014, to please Slender Man, an online horror movie character, he disappeared after she disabled an electronic surveillance device and left the group's home, authorities said Sunday.
Madison police issued an alert Sunday Morgan Geysernow 23, says she was last seen around 8pm on Saturday with an adult acquaintance.
“If you see Geyser, call 911,” the message said, adding that she cut off her “Department of Corrections monitoring bracelet.”
Geyser was placed in a group home earlier this year after being paroled from the Winnebago Mental Health Institute. She was sent to a psychiatric institute in 2018 after pleading guilty to attempted first-degree murder as part of a deal with prosecutors to avoid prison time.
Geyser's attorney, Tony Cotton, did not immediately return a message left Sunday.
Authorities say Geyser and her friend Anissa Weier were 12 years old when they lured their classmate Payton Leitner to a suburban Milwaukee park after a sleepover. Geyser stabbed Leitner more than a dozen times while Weier egged her on. Leitner barely survived.
The girls later told investigators that they attacked Leitner to earn the right to be Slender Man's servants, and they were afraid that he would harm their families if they did not follow through.
“Slender Man” was created online by Eric Knudson in 2009 as a mysterious figure embedded in everyday images of children playing. He has become a popular boogeyman, appearing in video games, online stories and 2018 film.
Weier pleaded guilty to attempted second-degree murder. She was also sent to a psychiatric center and granted release in 2021.
