St. Cloud man sentenced after traveling to meet minor he solicited online

Nathan Paul Grondahl learned his fate in a federal court this week.

A central Minnesota man will spend more than a decade behind bars on federal sex crime charges.

Nathan Paul Grondahl, a 25-year-old St. Cloud resident, has been sentenced to 135 months — a little over 11 years — in prison for traveling to meet a 13-year-old girl he had solicited for sex online.  

Per a release from the U.S. Attorney's Office of South Dakota, Grondahl left his home in late 2019 to meet the victim in Hartford, South Dakota, "for the purpose of engaging in illegal sexual conduct" with her.

The release says he also "requested that the minor female send him nude pictures of herself."

Prosecutors say he originally met the girl on social media and "had been communicating with her for a few days." 

Grondahl pleaded guilty to the charge in March. He had been facing additional charges in connection with the case; a release from December 2019 indicates he was also indicted on counts of child pornography production and transferring obscene material to a minor. 

At the time, he was facing a possible life sentence; federal authorities did not specify whether a plea deal had been made for this week's sentencing.

The release says Grondahl has been given until June 28, 2021, to self-surrender. 

Both the Minnehaha County Sheriff’s Office and the FBI investigated the case.
