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

United States Attorney Ron Parsons announced that a Porcupine, South Dakota, woman convicted of Second Degree Murder was sentenced on July 17, 2018, by Chief Judge Jeffrey L. Viken, U.S. District Court.

Katrina Pauline Shangreaux, a/k/a Katrina Shangreau, a/k/a Katrina White Whirlwind, age 30, was sentenced to 40 years in federal prison, to be followed by  5 years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Shangreaux was charged on August 9, 2016.  The conviction relates to Shangreaux killing her own child by hitting, kicking, and biting him in July 2016 at Porcupine.   

U.S. Attorney Parsons expressed great satisfaction with the collaborative investigation between federal and tribal officials.  "Only by working together to vindicate the rights of victims of crime, particularly those most vulnerable among us, can we achieve results such as this," said Parsons. 

"While no sentence will bring Kylen back or take away the pain from his death, we are pleased with a sentence that ensures the defendant cannot harm another child again," said Jill Sanborn, Special Agent in Charge of the FBI's Minneapolis Division.  "I am grateful that the collective efforts of the Oglala Tribe's Department of Public Safety, the Bureau of the Indian Affairs, the U.S. Attorney's Office and our FBI Agents assigned to this case helped bring justice to a helpless little boy who couldn't defend himself."

The investigation was conducted by the Federal Bureau of Investigation, the Bureau of Indian Affairs Office of Justice Services, and the Oglala Sioux Tribe Department of Public Safety.  Assistant U.S. Attorneys Sarah B. Collins and Megan J. Poppen prosecuted the case.

Shangreaux was immediately turned over to the custody of the U.S. Marshals Service.
