Porcupine Man Sentenced to 15 Years in Federal Prison

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Court Judge Jeffrey L. Viken has sentenced a Porcupine, South Dakota, man convicted of Voluntary Manslaughter. The sentencing took place on May 22, 2023.

Trey New Holy, 30, was sentenced to 15 years in federal prison, followed by three years of supervised release, and ordered to pay $100 special assessment to the Federal Crime Victims Fund.

New Holy was indicted for Second Degree Murder by a federal grand jury in September of 2022. He pleaded guilty on February 17, 2023.

The conviction stems from New Holy beating an individual after an altercation on September 3, 2022, in Porcupine. The victim sustained multiple blunt traumatic injuries to his head and body.  He ultimately succumbed to his injuries.

This case was investigated by the FBI and the Oglala Sioux Tribe Department of Public Safety. Assistant U.S. Attorney Megan Poppen prosecuted the case.

New Holy was immediately remanded to the custody of the U.S. Marshals Service.
