A Rapid City man has been sentenced to three and a half years in federal prison for illegally possessing ammunition. U.S. District Judge Camela C. Theeler handed down the sentence to Dylan Sanchez, 33, on September 29, 2025. In addition to the prison term, Sanchez will serve three years of supervised release and must pay a $100 special assessment to the Federal Crime Victims Fund.
Sanchez was indicted by a federal grand jury in September 2024 and pleaded guilty on July 21, 2025. According to court records, law enforcement stopped Sanchez in Rapid City on April 10, 2024, for speeding. After failing a field sobriety test, he was arrested and his vehicle was searched. Officers found over 200 rounds of ammunition, pistol magazines—including an extended magazine—cocaine, and distributable amounts of marijuana in his car. Sanchez is barred from possessing ammunition due to a prior 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,” according to United States Attorney Alison J. Ramsdell.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the Rapid City Police Department investigated the case. Assistant U.S. Attorney Benjamin Schroeder prosecuted it.
Sanchez was immediately remanded into custody by the U.S. Marshals Service.
