A federal judge has sentenced a man from Lancaster, California, who had been convicted of Conspiracy to Distribute Controlled Substances, including methamphetamine and fentanyl. The sentencing took place on July 21, 2025.
Clarence Williams, a/k/a “CJ,” 34, was sentenced to 21 years and 10 months in federal prison, followed by 5 years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.
Williams was indicted for Conspiracy to Distribute Controlled Substances by a federal grand jury in September 2024. He pleaded guilty on March 5, 2025, to conspiracy to distribute 500 grams or more of a mixture containing methamphetamine.
Williams is from Lancaster, California, and came to Sioux Falls to sell methamphetamine and fentanyl. Williams sourced the drugs from California, and worked with others from California and South Dakota to distribute fentanyl and methamphetamine in the Sioux Falls area using vehicles and the postal system. Throughout the investigation, law enforcement seized approximately 2 kilograms of fentanyl pills/powder through intercepted parcels and search warrants at a residence in Sioux Falls. The group also trafficked multiple pounds of methamphetamine. Throuhgout his involvement in the conspiracy, Williams also possessed firearms, three of which were seized by law enforcement during the investigation. In total, the group trafficked approximately 3 kilograms of fentanyl in pill and powder form and over 20 pounds of methamphetamine.
“This case is yet another example of the tremendous collaboration taking place between federal, state, and local law enforcement agencies to dismantle drug trafficking organizations in South Dakota,” said U.S. Attorney Alison J. Ramsdell. “Williams will rightfully spend the next two decades of his life in federal prison for callously exploiting drug addictions for his own financial gain.”
“Those attempting to harm members of our South Dakota communities by pushing poisons like fentanyl and methamphetamine should take note of this sentencing,” Drug Enforcement Administration (DEA) Omaha Division Acting Special Agent in Charge Rafael Mattei said. “Our agents leave no stone unturned as they work to locate and arrest the drug trafficking criminals who look to profit by inflicting pain and suffering on others. These attempts won’t fly in South Dakota. You will be brought to justice and you will serve time.”
This case was investigated by the DEA, United States Postal Inspection Service, and the Sioux Falls Area Drug Task Force. Assistant U.S. Attorney Mark Hodges prosecuted the case.
