Michael Barrera, an 18-year-old from Mission, South Dakota, has been sentenced to 15 years in federal prison for voluntary manslaughter. The sentence was handed down by U.S. District Judge Eric C. Schulte on February 23, 2026.
Barrera will also serve three years of supervised release following his prison term and must pay a $100 special assessment to the Federal Crime Victims Fund. He was indicted by a federal grand jury in June 2025 and pleaded guilty on November 20, 2025.
The case relates to an incident that took place in May 2025 on the Rosebud Sioux Indian Reservation. According to court documents, Barrera drove to a residence near Mission while armed with a shotgun and confronted an adult male victim. An argument led to a struggle during which Barrera shot the victim in the left shoulder, resulting in the victim’s death. Barrera then fled the scene but was arrested on June 4, 2025 at a residence in Rapid City, South Dakota.
“This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results,” according to U.S. Attorney Ron Parsons.
The prosecution was handled by the U.S. Attorney’s Office under provisions of the Major Crimes Act—a federal statute requiring certain violent crimes committed in Indian Country be prosecuted federally rather than at the state level.
The investigation involved multiple agencies including Rosebud Sioux Tribe Law Enforcement Services, FBI, U.S. Marshals Service, Pennington County Sheriff’s Office, and Rapid City Police Department. Supervisory Assistant U.S. Attorney Kirk Albertson prosecuted the case.
Barrera was immediately remanded into custody following sentencing.
