A Sioux City man has been sentenced to 20 years in federal prison after pleading guilty to charges related to the sexual exploitation of a minor and distribution of child pornography.
Bryce Bock, 32, entered his guilty plea on April 7, 2025. According to evidence presented at his plea and sentencing hearings, Bock coerced a minor under the age of 18 into engaging in sexually explicit conduct for the purpose of producing visual depictions between July 1, 2022, and July 2, 2024. Investigators found that Bock used an app called Anonymous Chat to send and receive images of child pornography. Some of these images involved toddlers and included sadistic and masochistic conduct. A forensic review of his phone revealed he possessed 24 images of child sexual abuse material, including those depicting a known minor victim.
United States District Court Judge Leonard T. Strand handed down the sentence in Sioux City on September 3, 2025. In addition to the prison term of 240 months, Bock was ordered to pay $1,200 in fines and assessments and will serve a five-year term of supervised release following his incarceration. There is no parole in the federal system.
Bock remains in the custody of the United States Marshals Service until he is transported to a federal prison.
