GREAT FALLS - A Michigan man who trafficked fentanyl onto the Rocky Boy's Indian Reservation was sentenced today to 18 months in prison, followed by three years of supervised release, Acting U.S. Attorney Mark Steger Smith said.
Deion Vincent Brown, 32, pleaded guilty in April 2026 to possession with intent to distribute controlled substances.
Chief U.S. District Judge Brian M. Morris presided.
The government alleged in court documents that Brown was part of group based out of Detroit that was bringing fentanyl into Montana and selling it around the Rocky Boy's Indian Reservation.
Following a tip, law enforcement pulled Brown over near the Reservation in October 2020 and found $15,756 in cash and 81 fentanyl pills. They learned Brown and others from his group had been staying at a home on the reservation. Investigators learned the group had used the house as a base of operations to distribute fentanyl onto the reservation.
The U.S. Attorney's Office prosecuted the case. The FBI conducted the investigation.
