GLENN CLIFFORD MESSMER, Child Sex Trafficking, Illinois 2023

CHICAGO — In a disturbing case of child exploitation, GLENN CLIFFORD MESSMER, a 48-year-old man from Darien, Illinois, has been sentenced to 19 years and seven months in federal prison for enticing numerous children to produce and record sexually explicit conduct.

Messmer communicated with children on the social media platforms Telegram and Snapchat under the screennames ‘coreyjohnsonnn’ and ‘jayyyjansen,’ and paid them to produce sexually explicit material in accordance with his instructions. He 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 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, Illinois Police Department provided valuable assistance.

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