Brockton woman admits stealing gun, vehicle in burglary on Fort Peck Indian Reservation

GREAT FALLS — A Brockton woman on April 24 admitted to stealing a firearm and a vehicle in a residential burglary on the Fort Peck Indian Reservation, U.S. Attorney Jesse Laslovich said today.

The defendant, Avis Big Track, 32, pleaded guilty to burglary. Big Track faces a maximum of 20 years in prison, a $250,000 fine and three years of supervised release.

Chief U.S. District Judge Brian M. Morris presided. The court will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors. Sentencing was set for Aug. 28. Big Track was detained pending further proceedings.

The government alleged that on Sept. 26, 2022, two homeowners reported a burglary of their home in Brockton, which is on the Fort Peck Indian Reservation. During the burglary, Big Track took a .45-caliber pistol and keys to a 2014 Chrysler, which she used to steal the Chrysler. Big Track was seen driving the stolen Chrysler, and she eventually admitted that she took the vehicle and had given the firearm to another individual, who put it in a safe with drugs. Law enforcement searched the safe and found the pistol and methamphetamine.

Assistant U.S. Attorney Amanda L. Myers is prosecuting the case. Fort Peck Tribal Law Enforcement conducted the investigation.
