For Immediate Release
U.S. Attorney's Office, District of South Dakota

United States Attorney Ron Parsons announced that a Peever, South Dakota, man convicted of abusive sexual contact was sentenced on November 4, 2019, by U.S. District Judge Charles B. Kornmann.

Thomas Dion DeMarrias, age 47, was sentenced to 240 months in federal prison, to be followed by 5 years of supervised release.  He was also ordered to pay $200 to the Federal Crime Victims Fund. 

According to court documents, between on or about May 9, 2010, and continuing through on or about May 8, 2011, in Roberts County, DeMarrias forcefully engaged in and attempted to engage in sexual contact with a juvenile victim, that is, sexual contact, by using force.  DeMarrias had the intent to abuse, humiliate, harass, and degrade the victim and had the intent to arouse and gratify his sexual desires. 

Between on or about June 22, 2009, and continuing through on or about June 21, 2011, in Roberts County, DeMarrias abused, tortured, and cruelly punished a child by using a dangerous weapon during and in relation to such conduct. 

“This defendant tortured and sexually abused his child victims in what can only be described as a house of horrors,” said U.S. Attorney Parsons.  “He deserves every day of this lengthy federal prison sentence.”

The investigation was conducted by the Federal Bureau of Investigation and the Sisseton-Wahpeton Oyate Sioux Tribal Law Enforcement.  Assistant U.S. Attorney Jeremy R. Jehangiri prosecuted the case.   

DeMarrias was remanded to the custody of the U.S. Marshals Service.
