Michael Barrera, an 18-year-old resident of Mission, South Dakota, has been sentenced to 15 years in federal prison after pleading guilty to voluntary manslaughter. U.S. District Judge Eric C. Schulte handed down the sentence on February 23, 2026. In addition to his prison term, Barrera will serve three years of supervised release and must pay a $100 special assessment to the Federal Crime Victims Fund.
Barrera was indicted by a federal grand jury in June 2025 and entered his guilty plea on November 20, 2025. The charges stem from an incident that took place in May 2025 on the Rosebud Sioux Indian Reservation. According to court records, Barrera drove to a residence near Mission while armed with a shotgun and confronted an adult male victim. An argument escalated into a struggle during which Barrera shot the victim in the left shoulder, resulting in a fatal wound. After the shooting, Barrera fled the scene and was arrested on June 4, 2025 at a residence in Rapid City.
The prosecution of this case falls under the Major Crimes Act, which requires certain violent crimes occurring in Indian Country to be prosecuted at the federal level rather than by state authorities.
The investigation involved multiple agencies including Rosebud Sioux Tribe Law Enforcement Services, the FBI, U.S. Marshals Service, Pennington County Sheriff’s Office, and Rapid City Police Department. Supervisory Assistant U.S. Attorney Kirk Albertson led the prosecution.
“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,” stated United States Attorney Ron Parsons. “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.”
Following sentencing, Barrera was immediately remanded into custody by U.S. Marshals Service.
