Sisseton Woman Charged with Misprision of a Felony

United States Attorney Ron Parsons announced that a Sisseton, South Dakota, woman was indicted by a federal grand jury for Misprision of a Felony on August 16, 2016.

Tylynn St. John, age 25, appeared before U.S. Magistrate Judge William D. Gerdes on February 5, 2018, and pled not guilty to the Indictment.

The maximum penalty upon conviction is 3 years of custody and/or a $250,000 fine, 5 years of supervised release, and $100 to the Federal Crime Victims Fund.  Restitution may also be ordered.

The Indictment alleges that on or about June 10, 2014, St. John failed to report a crime of which she had knowledge, to the proper authorities.  St. John and another are alleged to have witnessed an assault resulting in serious bodily injury and failing to report, or help seek aid, for a victim who ultimately died of her injuries.

The charge is merely an accusation and St. John is presumed innocent until and unless proven guilty. 

The investigation is being conducted by the Federal Bureau of Investigation.  Assistant U.S. Attorney Troy R. Morley is prosecuting the case.   

St. John was released pending trial, which has been set for April 10, 2018.
