Suburban Chicago Man Sentenced to More Than 19 Years in Prison for Producing Child Pornography

CHICAGO - A suburban Chicago man has been sentenced to more than 19 years in federal prison for enticing numerous children to produce and record sexually explicit conduct.

Using the screennames "coreyjohnsonnn" and "jayyyjansen," GLENN CLIFFORD MESSMER communicated with children on the social media platforms Telegram and Snapchat and paid them to produce sexually explicit material in accordance with his instructions. Messmer maintained detailed notes about his victims, identifying their names, ages, friends, years in school, physical features, and willingness to engage with him.

A law enforcement search of Messmer's electronic devices after his arrest in 2023 showed that he possessed more than 350,000 images and nearly 18,000 videos depicting child sexual abuse. Many of the images and videos depicted sexual abuse of prepubescent children, including some as young as four years old.

Messmer, 48, of Darien, Ill., pleaded guilty earlier this year to a federal child pornography charge. On Tuesday, U.S. District Judge Franklin U. Valderrama sentenced Messmer to 19 years and seven months in federal prison.

The sentence was announced by Morris Pasqual, Acting United States Attorney for the Northern District of Illinois, and Sean Fitzgerald, Special Agent-in-Charge of the Chicago Office of Homeland Security Investigations. The Darien, Ill. Police Department provided valuable assistance.

The government was represented by Assistant U.S. Attorneys Sushma Raju and Adam L. Rosenbloom.
