Alison J. Ramsdell U.S. Attorney | U.S. Attorney for the District of South Dakota
United States Attorney Alison J. Ramsdell has announced the sentencing of Clarence Williams, also known as "CJ," a 34-year-old man from Lancaster, California. Chief Judge Roberto A. Lange sentenced Williams to 21 years and 10 months in federal prison for conspiracy to distribute controlled substances, including methamphetamine and fentanyl. The sentence includes five years of supervised release and a $100 special assessment to the Federal Crime Victims Fund.
Williams was indicted by a federal grand jury in September 2024 and pleaded guilty on March 5, 2025, to conspiracy to distribute over 500 grams of methamphetamine. He traveled from California to Sioux Falls with the intent to sell methamphetamine and fentanyl sourced from California. Working with associates in both California and South Dakota, he used vehicles and the postal system for distribution.
During the investigation, law enforcement intercepted approximately two kilograms of fentanyl through parcels and search warrants executed at a residence in Sioux Falls. The group trafficked about three kilograms of fentanyl in pill and powder form, along with over 20 pounds of methamphetamine. Williams also possessed firearms during his involvement; three were seized by law enforcement.
U.S. Attorney Ramsdell commented on the case: “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.” She emphasized that Williams would spend two decades in prison for exploiting drug addictions for financial gain.
Rafael Mattei, Acting Special Agent in Charge of the DEA Omaha Division, stated: “Those attempting to harm members of our South Dakota communities by pushing poisons like fentanyl and methamphetamine should take note of this sentencing.” He assured that agents work diligently against drug traffickers who seek profit through others' suffering.
The investigation involved the DEA, United States Postal Inspection Service, and the Sioux Falls Area Drug Task Force. Assistant U.S. Attorney Mark Hodges prosecuted the case. Following his sentencing, Williams was remanded into custody by the U.S. Marshals Service.
