Friend of Wisconsin “Slender Man” stabber MORGAN GEYSER arrested for obstruction after pair captured in Illinois

Tuesday, November 25, 2025 -A friend of Morgan Geyser, one of the teens involved in the notorious Wisconsin “Slender Man” stabbing case, has been arrested for obstruction after the two were taken into custody in Illinois. 

Authorities say the pair were located following reports that Geyser had violated conditions linked to her release and monitoring requirements. Investigators allege the friend knowingly interfered with efforts to find Geyser, prompting the obstruction charge.

Officials have not released full details about the circumstances leading to their capture, but law enforcement sources indicate that the friend may have helped Geyser avoid detection while authorities searched across state lines. 

The arrest underscores the heightened scrutiny surrounding Geyser’s movements, given the seriousness of the original case and ongoing concerns about compliance with court-imposed restrictions. Illinois police coordinated with Wisconsin officials to secure the pair without incident.

The case is now expected to trigger a review of Geyser’s supervision terms, with prosecutors signaling they may pursue additional legal action if violations are confirmed. 

For families connected to the original stabbing, the incident has revived painful memories and renewed debate over how high-risk juvenile offenders should be monitored once they re-enter the community. Authorities say more updates will follow as the investigation continues.
