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

United States Attorney Randolph J. Seiler announced that a Marty, South Dakota, man convicted of Aggravated Sexual Abuse was sentenced on October 23, 2017, by U.S. District Judge Karen E. Schreier.

Gary Cournoyer, age 55, was sentenced to 135 months in custody, followed by 10 years of supervised release.  He was also ordered to pay $100 to the Federal Crime Victims Fund.

Cournoyer was indicted for aggravated sexual abuse by a federal grand jury on April 5, 2016.  He pled guilty on October 23, 2017.

Gary Cournoyer had sexual contact with an 11 year-old girl in January 2016.  The contact occurred in Cournoyer’s home in Charles Mix County.  Law enforcement was contacted after a relative discovered suspicious messages on a computer between Cournoyer and the girl.  The girl was interviewed and disclosed that Cournoyer had the sexual contact with her after he brought her to his home to do some laundry.  Investigators also learned that another child witnessed the sexual act. 

This case was investigated by the Federal Bureau of Investigation.  Assistant U.S. Attorney Jeffrey C. Clapper prosecuted the case.

Cournoyer was immediately turned over to the custody of the U.S. Marshals Service.
