SIOUX FALLS – Each year on February 11, more than one hundred countries around the world celebrate “Safer Internet Day.” The U.S. Attorney’s Office for the District of South Dakota takes this opportunity to remind the community that the Internet is often used for the sexual exploitation of children. In 2024, the U.S. Attorney’s Office, alongside local, state, and federal law enforcement partners, prosecuted more than 50 cases involving child exploitation and/or the production or receipt of child pornography originating on the Internet.

For example, in April 2024, the U.S. Attorney’s Office secured a conviction against Tyler Grimes, a 26-year-old man from Aldie, Virginia, who used the Internet-based application Omegle and his cellular phone to entice a minor to engage in sexually explicit activity. The minor was born in February 2014, making her seven years old at all relevant times. During his communications with the minor, who lived in Rapid City, South Dakota, Grimes repeatedly asked her for nude photos and videos of herself. She complied. After Grimes’ communications were discovered by the minor’s father, the minor was forensically interviewed. Later, many images and videos of child pornography between Grimes and the victim were located on the victim’s iPad. In August 2024, Grimes was sentenced to ten years in federal prison.

In June 2024, October 2024, and February 2025, Justin Preuschl, age 27, of Sioux Falls, South Dakota, was indicted for federal charges involving the exploitation of minors. The Indictment alleges that starting in December 2022 and continuing into 2024, Preuschl engaged in sexually explicit communications over the Internet with multiple juvenile female victims. The Indictment further alleges that Preuschl pretended to be a 15-year-old male, pressured the victims into sending him sexually explicit materials, and sent pictures of male genitals to the victims. Preuschl was employed as a teacher at Whittier Middle School in Sioux Falls at the time of many of the charged offenses.*

It is of vital importance that parents and guardians talk frequently and openly with children about responsible Internet use. It is also essential that the community understands the warning signs of cyberbullying and sextortion, including:

  1. Sudden changes in behavior, such as becoming withdrawn, anxious, or secretive;
  2. Abruptly deleting social media accounts or frequently creating new accounts;
  3. Turning offs or hiding devices in the presence of a parent or other adult;
  4. Clearing their web browser cache and/or history;
  5. Unexplained money or gift cards; and
  6. Spending less time with friends.

If you are concerned about particular online activity, please contact local law enforcement.
