Pine Ridge Man Sentenced to Over 3 Years in Federal Prison for Manslaughter and Firearm Possession

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Camela C. Theeler has sentenced a Pine Ridge, South Dakota, man convicted of Involuntary Manslaughter and Possession of a Firearm by a Prohibited Person. The sentencing took place on June 2, 2025.

Daeshawn Poor Bear, 19, was sentenced to three years and one month in federal prison, followed by three years of supervised release. He was ordered to pay restitution and $200 in special assessments to the Federal Crime Victims Fund.

Poor Bear was indicted for the charges by a federal grand jury in October 2024. He pleaded guilty on January 8, 2025.

Poor Bear, the victim, and two other friends consumed alcohol and edibles containing THC and smoked THC wax at an abandoned trailer in Pine Ridge on the evening of September 2, 2024. The victim and the other friends were all juveniles. The victim threw a firearm onto a bed near Poor Bear. Poor Bear picked up the firearm, pointed it at the victim, and pulled the trigger. The bullet struck the victim and killed him. Poor Bear and the other two friends ran to Poor Bear’s mother’s residence. Poor Bear’s mother called 911. The Oglala Sioux Tribe Department of Public Safety arrived at the abandoned residence and found that the victim had passed away. Poor Bear has a history of using THC, making him prohibited by law from possessing a firearm.

This matter was prosecuted by the U.S. Attorney’s Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court.

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

Poor Bear was immediately remanded to the custody of the U.S. Marshals Service.
