Mission Man Sentenced for Sexual Abuse of a Minor

United States Attorney Ron Parsons announced that a Mission, South Dakota, man convicted of Sexual Abuse of a Minor was sentenced on June 25, 2018, by U.S. District Judge Roberto A. Lange.

Matthew Peneaux, a/k/a Matthew Swalley, age 34, was sentenced to 37 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 $100.  Restitution may also be ordered.

Peneaux was indicted by a federal grand jury on October 24, 2017.  He pled guilty on April 11, 2018.

The conviction stemmed from events that occurred in 2015 and 2016.  Between March 28, 2015, and April 30, 2016, Peneaux repeatedly engaged in sexual intercourse with a girl who was between 12 and 13 years old.  Peneaux was aware that the victim was under the age of 16 and therefore unable to consent to any sexual activity with him.

This case was investigated by the Federal Bureau of Investigation and the Rosebud Sioux Tribe Law Enforcement Services.  Assistant U.S. Attorney Kirk Albertson prosecuted the case.

Peneaux was ordered to report to the custody of the U.S. Marshals Service on June 26, 2018.
