TULSA, OK — A 34-year-old Collinsville man has been sentenced to 25 years in federal prison for recording minor children in a bathroom, grooming a child online, and receiving and possessing child sexual abuse material.
U.S. District Judge Sara E. Hill ordered Thomas Joshua Keizer to serve 300 months in federal prison, followed by a lifetime term of supervised release. Keizer was also ordered to pay $11,000 in restitution and will be required to register as a sex offender upon his release.
Keizer pleaded guilty to two counts of Sexual Exploitation of a Child, one count of Receipt of Child Pornography, and one count of Possession of Child Pornography.
NCMEC CyberTip Prompts Federal Investigation
The case began in November 2024 when Homeland Security Investigations (HSI) initiated an inquiry based on a CyberTip from the National Center for Missing and Exploited Children (NCMEC).
Court documents established that Keizer utilized the Discord messaging platform to engage in sexually graphic messaging with a 12-year-old child. The subsequent investigation revealed that Keizer actively used the platform to locate and groom minor children.
Federal agents later executed a search warrant at Keizer’s Collinsville home and seized multiple electronic devices. A forensic review of the hardware uncovered 568 images and 11 videos of child sexual abuse material, including media depicting toddlers and prepubescent children.
Hidden Bathroom Camera Discovered
During the forensic analysis of the seized electronics, agents discovered that Keizer had hidden a recording device inside a bathroom to capture children using the restroom.
According to court records, Keizer used the hidden camera between July 2020 and August 2024 to capture more than 1,835 images of two additional minor children who were under the age of 10.
Victim Identification and Restitution
The illicit media recovered from Keizer’s devices was submitted to the National Child Victim Identification System, managed by NCMEC. Technicians successfully identified 13 victims whose images had been previously cataloged in the system. The identified victims were notified and permitted to submit victim impact statements to the court. The $11,000 in ordered restitution will be paid directly to the victims who requested it.
The criminal investigation was conducted jointly by Homeland Security Investigations and the Collinsville Police Department. Assistant U.S. Attorney Valeria Luster prosecuted the case on behalf of the government.
Keizer will remain in federal custody while awaiting transfer to a U.S. Bureau of Prisons facility.
