United States Attorney Brendan V. Johnson announced that a Mission, South Dakota, man has been indicted by a federal grand jury for Aggravated Sexual Abuse, Assault with a Dangerous Weapon, Assault Resulting in Serious Bodily Injury, and Child Abuse.

Frederick Leo Marshall, age 56, was indicted on December 9, 2014. He appeared before U.S. Magistrate Judge Mark A. Moreno on December 15, 2014, and pled not guilty to the Indictment.

The maximum penalty upon conviction is up to life in prison and/or a $250,000 fine, not less than five years of supervised release, and $700 to the Federal Crime Victims Fund. Restitution may also be ordered.

The Indictment alleges that on or about October 30, 2014, Marshall knowingly engaged and attempted to engage in a sexual act with a female victim. He also allegedly assaulted the same victim with a sword, which resulted in serious bodily injury. On the same date, Marshall allegedly abused, exposed, tortured, tormented, and cruelly punished four minor victims.

The charges are merely accusations and Marshall is presumed innocent until and unless proven guilty.

The investigation is being conducted by the Federal Bureau of Investigation and the Rosebud Sioux Tribe Law Enforcement Services. Assistant U.S. Attorney Tim Maher is prosecuting the case.

Marshall was remanded to the custody of the U.S. Marshals Service pending trial. A trial date has not been set.
