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 in 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 Weierr, 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.

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 captured later that day. Both were later found not guilty by reason of mental defect or disease in 2017 and sentenced to mental confinement.
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 several years before she was placed in a group home this year.
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, are asking anyone who sees her to call 911.
