Box Elder man admits assaulting woman with knife on Rocky Boy’s Indian Reservation

GREAT FALLS - A Box Elder man on Monday admitted to assaulting a woman by cutting her face with a knife during an argument on the Rocky Boy's Indian Reservation, U.S. Attorney Jesse Laslovich said today.

The defendant, Colten Tyrone Small, also known as Colton Swan, 24, pleaded guilty to assault with a dangerous weapon and assault resulting in serious bodily injury. Small faces a maximum of 10 years in prison, a $250,000 fine and three years of supervised release on each charge.

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 Jan. 29, 2025. Small was detained pending further proceedings.

In court documents, the government alleged that in the early morning hours of May 3, 2023, Small punched the victim, identified as Jane Doe, in the face while he held a butcher knife in a residence in Box Elder, on the Rocky Boy's Reservation. A witness to the assault told law enforcement that Small sliced Doe's face in the residence. Small and Doe argued, and the fight got more aggressive. After Small cut Doe's face, the witness beat up Small. There was some fentanyl and alcohol use occurring at the time. Doe was treated for facial injuries from the knife at Northern Montana Hospital.

The U.S. Attorney's Office is prosecuting the case. The FBI and Rocky Boy's Law Enforcement investigated the case.
