Slender Man stabber found at Illinois truck stop; companion charged, extradition hearing set
Morgan Geyser, 23, the woman known as the "Slender Man" stabber, was located early Monday sleeping behind a truck stop in Posen, Illinois, and taken into custody after initially refusing to identify herself; a 42-year-old male companion — who police say gave a false name — was charged with obstructing identification and trespassing and later released. An extradition hearing in Cook County is scheduled, and authorities say Madison police were not alerted for nearly 12 hours after Geyser’s GPS ankle monitor malfunctioned; she had been living in a group home after release earlier this year from Winnebago Mental Health Institute, and her attorney has expressed concerns about possible exploitation by older men.
