Sudbury Man Pleads Guilty to Child Pornography Offenses

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

BOSTON – A Sudbury man pleaded guilty on May 17, 2023 to child pornography charges.

Tyson Tu, 50, pleaded guilty to one count of receipt of child pornography and one count of possession of child pornography. U.S. District Court Judge Denise J. Casper scheduled sentencing for Aug. 9, 2023. Tu was indicted by a federal grand jury in October 2021. 

In May 2020, Tu was identified as the subscriber of an IP address downloading child pornography from a peer-to-peer file sharing network. During a search of Tu’s residence on April 13, 2021, multiple electronic devices were seized – one of which was actively downloading and sharing child pornographic files at the time. Three of the seized devices were found to contain child pornography files. It was determined that between approximately Feb. 20, 2021 through April 13, 2021, Tu received child pornography. 

The charge of receipt of child pornography provides for a sentence of at least five years and up to 20 years in prison, at least five years and up to a lifetime of supervised release and a fine of $250,000. The charge of possession of child pornography provides for a sentence of up to 20 years in prison, at least five years and up to a lifetime of supervised release and a fine of $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

Acting United States Attorney Joshua S. Levy; Michael J. Krol, Acting Special Agent in Charge of Homeland Security Investigations in New England; and Sudbury Police Chief Scott Nix made the announcement today. Assistant U.S. Attorney Suzanne Sullivan Jacobus of Levy’s Major Crimes Unit is prosecuting the case.  

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