Eagle Butte Man Charged With Assault And Victim Tampering

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

United States Attorney Brendan V. Johnson announced that an Eagle Butte, South Dakota, man has been indicted by a federal grand jury for Assault Resulting in Substantial Bodily Injury to an Intimate Partner, Assault with a Dangerous Weapon, and Victim Tampering.

Sydney Gilbert Garreau, age 36, was indicted on November 13, 2014.  He appeared before U.S. Magistrate Judge Mark A. Moreno on November 21, 2014, and pled not guilty to the Indictment.  

The maximum penalty upon conviction is up to 20 years in custody and/or a $250,000 fine, 3 years of supervised release, and up to $300 to the Federal Crime Victims Fund.  Restitution may also be ordered.

The Indictment alleges that on or about September 20, 2014, Garreau assaulted his intimate and dating partner with a dangerous weapon, which resulted in substantial bodily injury.  He also knowingly intimidated, threatened, and corruptly persuaded his partner by threatening her with bodily injury or death if she reported the assault to law enforcement officials.

The charges are merely accusations and Garreau is presumed innocent until and unless proven guilty. 

The investigation is being conducted by the Cheyenne River Sioux Tribe Law Enforcement Services.  Assistant U.S. Attorney Meghan N. Dilges is prosecuting the case.   

Garreau was remanded to the custody of the U.S. Marshals Service pending trial.  A trial date has not been set.
