U.S. Attorney's Office, Southern District of Iowa

Des Moines, IA – A Nevada, Iowa man was sentenced today to 121 months in prison following his guilty plea for possession of child pornography.

According to court documents, on or about December 21, 2021, William Ryan Buttermore, age 24, knowingly possessed visual depictions of child pornography, including 44 images and four videos, some of which depicted infants and other minors younger than 12 years old. Buttermore downloaded the material from the internet. In addition, Buttermore used an account on Kik Messenger to transport child pornography to others and to encourage others to produce child pornography and engage in sex acts with children. Following his prison term, Buttermore must also serve a ten-year term of supervised release. There is no parole in the federal system.

United States Attorney Richard D. Westphal of the Southern District of Iowa made the announcement. The Story County Sheriff’s Department, in conjunction with the Iowa Crimes Against Children Task Force, investigated the case. Assistant United States Attorney Kyle Essley prosecuted the case.

The case was brought as part of Project Safe Childhood. In 2006, the Department of Justice created Project Safe Childhood, a nationwide initiative designed to protect children from exploitation and abuse. Led by the U.S. Attorney’s Offices and the Department of Justice’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.
