Man Sentenced for Receipt of Child Pornography

For Immediate Release
U.S. Attorney's Office, Northern District of Oklahoma

A Tulsa man who possessed more than 600 images of child pornography was sentenced in federal court, announced Acting U.S. Attorney Clint Johnson.

U.S. District Judge Gregory K. Frizzell sentenced Matthew Steven Janson, 38, to seven years in federal prison followed by seven years of supervised release.

“Matthew Janson accessed and viewed hundreds of images of children being sexually abused,” said Acting U.S. Attorney Clint Johnson. “The demand for child pornography feeds an illicit industry that preys on the most vulnerable members of society. The U.S. Attorney’s Office remains relentless in its pursuit of those who produce and seek out depictions of child sexual abuse.”

Janson pleaded guilty in June after he knowingly used the internet to receive child pornography from April 18, 2016 to May 25, 2016.

According to the plea agreement, Janson admitted to possessing at least 600 images of child sexual abuse including the abuse of prepubescent minors who had not attained 12 years of age. The materials were possessed and knowingly accessed via Janson’s computer and within the Muscogee Nation Reservation.

Janson is a citizen of the Cherokee Nation. Janson’s state conviction was vacated due to the Supreme Court’s ruling in McGirt v. Oklahoma. He previously pleaded guilty in state court in 2017 and was sentenced to 10 years with 5 years of that time suspended.

The Tulsa Police Department, Oklahoma State Bureau of Investigation and U.S. Immigration and Customs Enforcements’ Homeland Security Investigations conducted the investigation. Assistant U.S. Attorney Cymetra M. Williams prosecuted the case.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who sexually exploit children, and to identify and rescue victims.
