Lodge Grass woman admits trafficking meth, fentanyl in multi-state drug ring centered on Crow Indian Reservation

U.S. Attorney's Office, District of Montana

BILLNGS — A Lodge Grass woman today admitted to trafficking methamphetamine and fentanyl as part of a large-scale, multiple-state narcotics organization that was centered on the Crow Indian Reservation, U.S. Attorney Jesse Laslovich said.

Yvon Lizbeth Lopez-Flores, 29, pleaded guilty to possession with intent to distribute controlled substances. Lopez-Flores faces a mandatory minimum of five years of imprisonment, a $5 million fine and at least four years of supervised release.

U.S. Magistrate Judge Timothy J. Cavan presided. A sentencing date will be set before U.S. District Judge Susan P. Watters. The court will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors. Lopez-Flores was detained pending further proceedings.

In court documents, the government alleged that federal law enforcement, in a collaborative effort with local and tribal law enforcement, conducted a large-scale, multiple-state investigation into narcotics trafficking centered on multiple properties on the Crow Indian Reservation. The properties, including one referred to as Spear Siding, were a source of supply for meth for both the Crow and Northern Cheyenne Indian Reservations. Lopez-Flores is one of the individuals associated with the investigation.

In July 2022, law enforcement learned that Lopez-Flores was identified as a distributor of meth and was working with several individuals on the Crow and Northern Cheyenne Indian Reservations.

Assistant U.S. Attorneys are prosecuting the case. The Bureau of Indian Affairs, Drug Enforcement Administration and FBI conducted the investigation.

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.
