Eagle Butte Man Sentenced for Conspiracy to Distribute a Controlled Substance

PIERRE - United States Attorney Alison J. Ramsdell announced today that Chief Judge Roberto A. Lange, U.S. District Court, has sentenced an Eagle Butte, South Dakota, man convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on June 12, 2023.

Sydney Garreau, age 44, was sentenced to 12.5 years in federal prison, followed by four years of supervised release, a $1,000 fine, and a special assessment to the Federal Crime Victims Fund in the amount of $100.

Garreau was indicted by a federal grand jury in August of 2022. He pleaded guilty on February 22, 2023.

The conviction stemmed from a drug conspiracy beginning in February of 2021 and continuing until August of 2022, when Garreau was involved with several other individuals to distribute methamphetamine in and around the central South Dakota area, including on the Cheyenne River Sioux Indian Reservation. Garreau received distributable quantities of methamphetamine from a source of supply and then distributed the methamphetamine to various individuals on the reservation.  Methamphetamine is a Schedule II controlled substance.

This case was investigated by the Cheyenne River Sioux Tribe Law Enforcement and the Northern Plains Safe Trails Drug Task Force. Assistant U.S. Attorney Meghan N. Dilges prosecuted the case.

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