A Sioux City man has been sentenced to 20 years in federal prison for sexually exploiting a minor and distributing child pornography. Bryce Bock, 32, received the sentence on September 3, 2025, following his guilty plea in April to charges of sexual exploitation of a minor and distribution of child pornography.
According to evidence presented during the plea and sentencing hearings, Bock used and coerced a minor under the age of 18 between July 1, 2022, and July 2, 2024, to engage in sexually explicit conduct for the purpose of producing visual depictions. He admitted to using an app called Anonymous Chat to receive and send images of child pornography. Some images included toddlers and depicted sadistic and masochistic conduct. A forensic review of Bock’s phone revealed he possessed 24 images of child sexual abuse material, including images involving a known minor victim.
Bock was sentenced by United States District Court Judge Leonard T. Strand in Sioux City. In addition to his prison term of 240 months, he was ordered to pay $1,200 in fines and assessments. Upon release from prison, Bock will be subject to five years of supervised release. There is no parole in the federal system.
Bock remains in the custody of the United States Marshal until he is transported to a federal prison.
The case was prosecuted as part of Project Safe Childhood, an initiative started by the Department of Justice in May 2006 aimed at combating child sexual exploitation and abuse by coordinating efforts among federal, state, and local agencies.
