A Parmelee, South Dakota man has been sentenced to nearly four years in federal prison after being convicted of two counts of domestic assault as a habitual offender. The sentencing was announced by U.S. Attorney Ron Parsons and took place on February 23, 2026, before U.S. District Judge Eric C. Schulte.
Hehaka Thunder Hawk, 42, received a sentence of three years and eight months in federal prison. He will also serve three years of supervised release following his incarceration and must pay a $200 special assessment to the Federal Crime Victims Fund.
Thunder Hawk was indicted by a federal grand jury in May 2025 and pleaded guilty on November 24, 2025.
According to court records, the convictions relate to two separate assaults against an intimate partner on the Rosebud Sioux Indian Reservation. On November 12, 2021, Thunder Hawk unlawfully entered a residence in Parmelee and assaulted a woman by pulling her hair and punching her face before fleeing the scene. On February 10, 2025, he entered the same woman’s home through a broken window while she was sleeping and assaulted her again, causing fractures to her nose and orbital bone. At the time of both incidents, Thunder Hawk had three prior convictions for domestic abuse in Rosebud Sioux Tribal Court.
The case was investigated by Rosebud Sioux Tribe Law Enforcement Services and prosecuted by Assistant U.S. Attorney Kimberly Zachrison.
Thunder Hawk was immediately remanded into custody of the U.S. Marshals Service.
