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