DES MOINES, IA – The U-S Attorney’s Office for the Southern District of Iowa reports that on November 2, 2023, a Des Moines man was sentenced to 32 years in prison after pleading guilty to the crime of transportation of child pornography and two additional years for violating his term of federal supervised release.

In 2022, Adam Christopher Evans, 39, amassed an extensive collection of child sexual abuse material. Over several months, Evans stockpiled over 500 images and 69 videos depicting the sexual exploitation of children, including infants and toddlers.

In 2021, Evans was convicted in federal court of failure to register as a sex offender. He was required to register as a sex offender because of a 2011 conviction for sexual exploitation of a minor under Iowa law. Evan’s supervised release was revoked, and he was sentenced to two years consecutive to his 32-year sentence.

Following his prison term, Evans will be required to serve 10 years of supervised release. There is no parole in the federal system.

Homeland Security Investigations and the United States Probation Office investigated this case. Assistant United States Attorney Laura M. Roan prosecuted the case.

The case was prosecuted as part of the U.S. Department of Justice’s “Project Safe Childhood” initiative, which was started in 2006 as a nationwide effort to combine law enforcement investigations and prosecutions, community action, and public awareness in order to reduce the incidence of sexual exploitation of children.
