A Sioux City man has been sent to federal prison for his role in a methamphetamine conspiracy that distributed over 170 grams of pure methamphetamine in the Sioux City area.

Dean Christiansen, 64, was sentenced on November 18, 2025 in federal court in Sioux City to 134 months’ imprisonment for his involvement in the conspiracy to distribute methamphetamine. Christiansen was previously convicted in the Northern District of Iowa of conspiracy to distribute a controlled substance in December 2012.

Evidence presented at the plea and sentencing hearings showed that from May 2024 through about August 2024, Christiansen was involved in a conspiracy that distributed more than 170 grams of pure methamphetamine in the Sioux City area within 1,000 feet of a local elementary school.

Law enforcement conducted two controlled methamphetamine purchases from Christiansen in August 2024 and seized scales and marijuana during a search of Christiansen’s home. Christiansen admitted purchasing about 12 pounds of methamphetamine to repackage and distribute to others.

Christiansen must serve a seven-year term of supervised release following imprisonment. There is no parole in the federal system. Christiansen remains in custody of the United States Marshal until he can be transported to a federal prison.
