Convicted Sex Offender Sentenced to Over 19 Years in Federal Prison for Attempted Enticement of a Minor and Child Pornography

RAPID CITY - United States Attorney Ron Parsons announced today that U.S. District Judge Camela C. Theeler has sentenced a man from Rapid City, South Dakota, convicted of Attempted Enticement of a Minor Using the Internet and Receipt of Child Pornography. The sentencing took place on September 29, 2025.

Aaron Williams, Jr., 24, was sentenced to 19 years and seven months in federal prison, to be followed by 10 years of supervised release. Williams was ordered to pay $570 in restitution and $200 in special assessments to the Federal Crime Victims Fund. Williams was also ordered to forfeit his cell phone.

A federal grand jury indicted Williams for the charges in August 2024. He pleaded guilty on July 21, 2025.

During the 2024 Sturgis Bike Rally, the South Dakota Internet Crimes Against Children Task Force conducted an undercover anti-child exploitation operation. During the operation, Williams used his Reddit account and cell phone to send messages to a person he believed to be a 14-year-old girl, who was actually the undercover persona of an investigator with the Pennington County Sheriff’s Office. When Williams attempted to meet up with the girl to engage in sex acts, he was arrested. After Williams’ arrest, he called his father from jail, reported he had been arrested for child exploitation crimes, and requested that his dad get his “stuff” from Williams’ apartment. Shortly thereafter, Williams’ sister entered his apartment and removed several electronic devices. The devices were ultimately recovered by law enforcement. Analysis of Williams’ cell phone revealed hundreds of images of child pornography depicting infants, bestiality, and rape and bondage of children.

Williams was convicted in 2023 for Possession of Child Pornography, Viewing Child Pornography, and Distribution of Child Pornography, crimes committed during his military service in the United States Air Force. As a result of the previous conviction, he is required to register as a sex offender. On August 1, 2024, just days before his arrest, Williams had completed a term of federal supervised release.

This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse, launched in May 2006 by the Department of Justice. Led by the U.S. Attorneys’ Offices and the DOJ’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.

This case was investigated by the South Dakota Internet Crimes Against Children Task Force, Pennington County Sheriff’s Office, and Homeland Security Investigations. Assistant U.S. Attorney Heather Knox prosecuted the case.

Williams was immediately remanded to the custody of the U.S. Marshals Service.
