Minnesota Man Sentenced for Travel with Intent to Engage in Illicit Sexual Conduct with a Minor


Acting United States Attorney Dennis Holmes announced that a St. Cloud, Minnesota, man convicted of Travel with Intent to Engage in Illicit Sexual Conduct with a Minor was sentenced on June 14, 2021, by U.S. District Judge Karen E. Schreier.

Nathan Paul Grondahl, age 25, was sentenced to 135 months in federal prison, followed by 5 years of supervised release, and a special assessment to the Federal Crime Victims Fund in the amount of $5,100.

Grondahl was indicted by a federal grand jury on December 10, 2019.  He pled guilty on March 22, 2021.

The conviction stemmed from an incident on November 22, 2019, when Grondahl left his home in Minnesota to travel to Hartford, South Dakota, for the purpose of engaging in illegal sexual conduct with a 13-year old female.  Grondahl had met the minor on social media and had been communicating with her for a few days.  Grondahl also requested that the minor female send him nude pictures of herself.
