Sioux City Man Sentenced to 20 Years in Federal Prison for Production and Distribution of Child Pornography

A man who sexually exploited children and distributed child pornography was sentenced September 3, 2025, to 20 years in federal prison.

Bryce Bock, 32, from Sioux City, Iowa, received the prison term after an April 7, 2025, guilty plea to sexual exploitation of a minor and distribution of child pornography. 

Evidence at the plea and sentencing hearings showed that from July 1, 2022, through July 2, 2024, Bock used and coerced a minor under the age of 18 to engage in sexually explicit conduct for the purpose of producing visual depictions of such conduct.  Bock admitted to utilizing an app called Anonymous Chat to receive and send images of child pornography some included toddlers and sadistic and masochistic conduct.  A forensic review of Bock’s phone found he possessed 24 images of child sexual abuse material, including images of a known minor victim.  

Bock was sentenced in Sioux City by United States District Court Judge Leonard T. Strand.  Bock was sentenced to 240 months’ imprisonment and was ordered to pay $1,200 in fines and assessments.  He must also serve a 5-year term of supervised release after the prison term.  There is no parole in the federal system.

Bock is being held in the United States Marshal’s custody until he can be transported to a federal prison.

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 individuals who sexually exploit children, and to identify and rescue victims.  For more information about Project Safe Childhood, please visit www.usdoj.gov/psc.  For more information about Internet safety education, please visit www.usdoj.gov/psc and click on the tab “resources.”
