In July 2026, authorities arrested 44-year-old Matthew Sheffer, a teacher at a Libertyville middle school, following allegations that he created explicit imagery of students using artificial intelligence. Sheffer, who had been employed by the district for 18 years, has been placed on administrative leave as the legal process moves forward.
What happened
The investigation into Sheffer began after students reported that they believed their teacher was recording videos of them toward the end of the school year. Subsequent law enforcement review of Sheffer's phone revealed the presence of images of students that had been altered using artificial intelligence to create explicit content.
Libertyville police and the Lake County State's Attorney's Office characterized the case as a highly sensitive and complex investigation involving digital forensics. The inquiry relied on collaboration between multiple agencies, including the Cyber Crimes Division and the Lake County Children's Advocacy Center. Officials have stated that they are working to connect the impacted students and families with support services as the legal proceedings continue.
