One of the two people convicted in the 2014 Slender Man stabbing is missing after she cut off her monitoring bracelet and fled a group home over the weekend.
Morgan Geyser, who was granted condition release earlier this year, was last seen on the street where the group home is located in Sun Prairie, a suburb of Madison.
Police in Madison said Geyser was last seen with an adult acquaintance around 8 p.m. Saturday. Her whereabouts on Sunday morning were unknown, the Milwaukee Journal Sentinel reported.
Geyser, now 23, was placed in the group home to continue treatment for a psychotic spectrum disorder. She, along with co-defendant Anissa Weier, was charged with attempted homicide in the 2014 stabbing attack of their friend, Payton Leutner.
In 2014, when Geyser and Weier were both 12 years old, they lured Leutner, also 12, into a wooded area in Waukesha, not far from Milwaukee, and stabbed her 19 times.
The girls said they carried out the stabbing to appease the fictional character Slender Man.
During the attack, the girls forced Leutner to lie down on the ground. Using a kitchen knife she brought from home, Geyser repeatedly stabbed Leutner while Weier egged her on.
Leutner barely survived the attack, according to medical staff who treated her at the time.
Geyser and Weier were arrested later that day as they walked on Interstate 94. They told investigators that they attacked Leutner to earn the right to be Slender Man’s servants and feared he would hurt their families if they didn’t follow through.
They had planned to walk to Slender Man’s mansion in northern Wisconsin following the attack, they said at the time.
Both of the girls were found not guilty by reason of mental defect or disease in 2017 and sentenced to mental confinement.
The case drew widespread attention because of their fixation on the Slender Man character, who was created online in 2009 by Eric Knudson as a mysterious specter edited into everyday images of children at play.
Slender Man is typically depicted as a slim, spidery figure in a black suit with a featureless white face.
Weier received 25 years but was granted conditional release in 2021 on a 25-year commitment order. She was freed from electronic monitoring in 2023.
Meanwhile, Geyser was sentenced to 40 years of mental confinement. She lived in a psychiatric hospital in Oshkosh for seven years and was placed in a group home this year after three experts testified that she made progress battling her mental illness.
Under the conditions of her release she was to remain under state supervision with a GPS monitor.
Police in Madison, who were notified of Geyser’s disappearance Sunday morning, released a recent surveillance photo of Geyser. Authorities are asking anyone who sees her to call 911.
