Porcupine Man Sentenced to 12 Years in Federal Prison for Five Charges of Abusive Sexual Contact

RAPID CITY - United States Attorney Ron Parsons announced today that U.S. District Judge Camela C. Theeler has sentenced a Porcupine, South Dakota, man convicted of five charges of Abusive Sexual Contact. The sentencing took place on August 3, 2026.

Gary Pourier, 59, was sentenced to 12 years in federal prison for each count, followed by five years of supervised release. Each sentence was ordered to run concurrently. Further, Pourier was ordered to pay a $500 special assessment to the Federal Crime Victims Fund and a $5,000 special assessment pursuant to the Justice for Victims of Trafficking Act of 2015.

Pourier was initially indicted for Abusive Sexual Contact by a federal grand jury in August 2024. After his initial indictment, additional charges were added as two other victims came forward alleging abuse at the hands of the defendant. Four victims testified during the three-day jury trial in federal district court in Rapid City, South Dakota, beginning April 16, 2026. The jury found Pourier guilty of all counts.

In July of 2024, Pourier was at the Common Cents Convenience Store near Porcupine when he made contact with a 10-year-old female. Pourier sexually fondled the young girl inside the store. After the victim left the store, she reported to a guardian what had happened. Officers with the Oglala Sioux Tribe Department of Public Safety, as well as the Federal Bureau of Investigation, responded to the scene and the child's home. During its investigation, the FBI learned of additional victims.

This matter was prosecuted by the U.S. Attorney's Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian country be prosecuted in federal court as opposed to State court.

This case was investigated by the Federal Bureau of Investigation and the Oglala Sioux Tribe Department of Public Safety. Assistant U.S. Attorney Megan Poppen prosecuted the case.

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