July 28, 2026 – FRESNO, CA – Stephen Tyler Prock, 58, of Jamestown, was sentenced on Monday by U.S. District Judge Jennifer L.

Judge Thurston also ordered Prock to pay $23,000 in restitution to four victims whose images he possessed.

According to court documents, between May 2018 and March 2020, Prock received approximately 100 videos of CSAM and used a peer-to-peer file-sharing program to distribute CSAM to others around the world. On March 4, 2020, Prock was in the process of downloading more CSAM onto his computer when federal agents arrived at his home with a search warrant and seized his computer. 

On April 23, 2026, following a three-day trial, a jury found Prock guilty of receipt and distribution of CSAM.

Homeland Security Investigations conducted the investigation. Assistant U.S. Attorney Calvin Lee 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 the 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 those who sexually exploit children, and to identify and rescue victims.
