A 47-year-old social studies teacher at Twin Lakes High School in Monticello has been preliminarily charged with several felonies involving crimes against children, after a juvenile reported troubling online interactions to school officials. The teacher, identified as Michael Gilbert, is accused in court documents of exchanging messages with a victim that stretched from a disclosure of their age in summer 2024 into 2026, culminating in a video call this past April that investigators say he made from inside the school.
Case Traces Back to an Idaho Investigation
According to court documents described by fox59.com, the case against Gilbert began when a juvenile reported to school officials that a man later identified as Gilbert had been inappropriate with them online. The Indiana State Police Lafayette Post reportedly received a call from a detective working an Idaho case, according to the court documents cited in that report. Investigators say the victim disclosed their age to Gilbert in the summer of 2024, and that the two kept communicating afterward.
As reported by WKRC, police said Gilbert sent messages that included questions about masturbating with a high school teacher and being mothered with a child, and one message reportedly read, “You're going to mother me and our child.” Police also said Gilbert used live video calls with the victim and allegedly directed them to expose their body and pose in front of a camera. The station reports that messages between the two continued into 2026.
A Screenshot That Allegedly Pointed Back to the School
The most striking detail in the case centers on an April video call. Court documents say Gilbert asked the victim to answer a video call while he was on a break at school, and the victim later told investigators that Gilbert exposed his genitals and masturbated in what appeared to be a school restroom stall. The victim gave investigators a screenshot of the video's background, and authorities confirmed the image to be similar to that of the school's restrooms, per the same account.
Court documents list Gilbert's preliminary charges as promotion of child sexual trafficking, two counts of child exploitation, possession of child sexual abuse material, two counts of performance before a minor that is harmful to minors, and activity related to obscene performance. Monticello Twin Lakes High School did not respond to a request for comment by early Tuesday morning, the report notes.
Conflicting Accounts on Custody Status
Accounts differ on where the case stood as of Monday. WKRC reported that Gilbert was taken into custody around 4:41 p.m. that day. Fox59, however, reported that a warrant had been issued for Gilbert on Monday but had not yet been served at the time of its article. Hoodline could not independently resolve the discrepancy between the two accounts.
