For Immediate Release
U.S. Attorney's Office, District of South Dakota

SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schreier has sentenced a Sioux Falls, South Dakota, woman convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on February 28, 2023.

Tiffany Nicole Seidel, 31, was sentenced to 11 years and eight months in federal prison, followed by five years of supervised release. She was also ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Seidel was indicted for conspiracy to distribute a controlled substance by a federal grand jury in September of 2022. She pleaded guilty on December 2, 2022.

Seidel reached an agreement with co-conspirators to distribute 50 grams or more of pure methamphetamine in the District of South Dakota.  On April 7, 2022, she assisted her co-conspirators in completing the sale of one pound of methamphetamine to a confidential informant. She and her co-conspirators met the confidential informant in the parking lot of a grocery store, where they completed the sale of approximately 333.8 grams of methamphetamine, at 98% purity, for $4,600. Her involvement in the conspiracy ended in June of 2022, when she was arrested for her conduct.

This case was investigated by the Sioux Falls Area Drug Task Force and the Drug Enforcement Administration. This case was prosecuted by Special Assistant U.S. Attorney Paige Petersen, who also serves as a prosecutor with the South Dakota Attorney General’s Office.

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