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, the Madison Police Department said.

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.
