Rapid City Man Sentenced to 3 ½ Years in Federal Prison for Illegally Possessing Ammunition

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Camela C. Theeler has sentenced a man from Rapid City, South Dakota, convicted of Possession of Ammunition by a Prohibited Person. The sentencing took place on September 29, 2025.

Dylan Sanchez, 33, was sentenced to three years and six months in federal prison, followed by three years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Sanchez was indicted by a federal grand jury in September 2024. He pleaded guilty on July 21, 2025.

On April 10, 2024, in Rapid City, SD, Sanchez was stopped by law enforcement for traveling above the posted speed limit. After failing a field sobriety test, Sanchez was arrested and his vehicle inventoried. In his vehicle, law enforcement located over 200 rounds of ammunition, pistol magazines, including an extended magazine, cocaine, and distributable amounts of marijuana. Sanchez is prohibited from possessing ammunition because of a previous felony conviction.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

This case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the Rapid City Police Department. Assistant U.S. Attorney Benjamin Schroeder prosecuted the case.

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