RAPID CITY, S.D. U.S. Attorney Alison J. Ramsdell said Monday that Mason Neck, 35, of Rapid City, was sentenced to one year and one day in federal prison for not registering as a sex offender. In addition, Neck received a five-year supervised release sentence and a $100 special assessment to be paid to the Federal Crime Victims Fund.
After being found guilty of abusive sexual contact in 2019, Neck must update his sex offender registration within three business days of moving or changing jobs. Neck broke federal law when he moved out of his listed address in April 2024 without updating his registration, despite having first registered when he started a period of supervised release in September 2023. On May 8, 2024, he was taken into custody in Rapid City.
As part of the Department of Justice’s Project Safe Childhood effort, which aims to prevent child sexual exploitation and abuse, the case was prosecuted. To find criminals and safeguard victims, the program combines federal, state, and local resources.
The investigation was conducted by the U.S. Marshals Service, and the case was prosecuted by Senior Litigation Counsel Kirk Albertson. On November 25, 2024, U.S. District Judge Camela C. Theeler sentenced Neck, who was promptly remanded to the U.S. Marshals Service custody.
The DOJ’s continued dedication to upholding sex offender registration laws in order to safeguard public safety is demonstrated by this case.
