The woman convicted of brutally stabbing her sixth grade classmate to please the fictional horror character "Slender Man" has gone missing in Wisconsin, officials said.
Morgan Geyser, 22, cut off her Department of Corrections monitoring bracelet and left a group home Saturday night, theMadison Police Departmentsaid.
She was last seen in the area of Kroncke Drive around 8 p.m. local time with "an adult acquaintance," police said.
Madison police were notified that she was missing Sunday morning and her current whereabouts are unknown, officials said.
Officials released a recent image of Geyser from security footage this last month. Anyone who sees her is asked to call 911.
Her disappearance comes 11 months after a judge in January ruled for herrelease from a psychiatric hospital. She had spent nearly seven years inside the Winnebago Mental Health Institute and was then moved to a group home.
Geyser was 15 when she wassentenced to a maximum of 40 years in a mental hospitalfor the 2014 stabbing attack. She and another girl lured a classmate to a suburban Milwaukee park and attacked the girl, with Geyser stabbing her.
At the time all three girls were 12 years old, and the victimbarely survived.
Geyser and her classmate believed they had to attack the victim or riskSlender Man,the fictional boogeyman, coming after their families, defense lawyers said at the time.
Anthony Cotton, Geyser's attorney, shared avideostatement on social media urging for Geyser to turn herself in.
"We just heard the news that Morgan has walked away from the group home that she was housed at. Obviously it's in her best interest to turn herself in immediately and not continue with this course of action," he said. "If anybody has contact with Morgan, hears from her, or if Morgan happens to see this, turn yourself in. Do not continue to remain on the run like this."
