Eagle Butte Man Jasyn Curley Charged in Officer Assault

Jasyn Curley, a 22-year-old from Eagle Butte, South Dakota, is facing federal charges for assaulting a tribal law enforcement officer in an incident that prosecutors say crossed the line from defiance to violence. Indicted on February 14, 2018, by a federal grand jury, Curley stands accused of forcibly attacking, resisting, and impeding a Cheyenne River Sioux Tribe officer while the officer was carrying out official duties.

The attack allegedly occurred on November 17, 2017, when the officer attempted to perform a lawful duty. According to the indictment, Curley didn’t just resist—he made physical contact, escalating the confrontation into a direct assault on federal authority. The charge specifically alleges intimidation, interference, and physical resistance against a sworn officer, making it a federal offense.

Curley appeared in court on February 21, 2018, before U.S. Magistrate Judge Mark A. Moreno, where he formally entered a plea of not guilty. Despite his plea, the stakes are high: if convicted, he could face up to 8 years in federal prison, a $250,000 fine, 3 years of supervised release, and must pay $100 to the Federal Crime Victims Fund. The court also retains the right to order restitution.

The investigation was led by the Cheyenne River Sioux Tribe Law Enforcement Services, underscoring the complex jurisdictional realities on Native lands where federal and tribal authorities often work in tandem. The case is now in the hands of Assistant U.S. Attorney Jay Miller, who will prosecute under federal statutes designed to protect law enforcement from violent retaliation.

Following his arraignment, Curley was remanded into the custody of the U.S. Marshals Service, indicating judges perceived him as a potential flight risk or danger to the community. No trial date has yet been scheduled, leaving the case in legal limbo as both sides prepare for battle in what’s expected to be a tense courtroom showdown.

The charge remains an accusation, and Jasyn Curley is presumed innocent until proven guilty in a court of law. But the indictment sends a clear message: assaulting an officer—especially one operating under federal jurisdiction—comes with steep consequences. The people of Eagle Butte are watching, and so is the federal justice system.
