GREAT FALLS — An East Glacier man who admitted to beating one victim and stabbing another victim in two separate assaults on the Blackfeet Indian Reservation was sentenced on Jan. 10 to a total of 41 months in prison, to be followed by three years of supervised release, U.S. Attorney Jesse Laslovich said today.

Frank David Francis Boy, 25, pleaded guilty in 2023 to assault with a dangerous weapon and to assault resulting in serious bodily injury for separate incidents.

Chief U.S. District Judge Brian M. Morris presided.

In court documents, the government alleged that in the first assault, Boy was drinking alcohol with friends in East Glacier on Sept. 18, 2022. The group then went for a drive and ended up in Browning at a house party, where the victim, identified as John Doe lived. Boy and Doe arm-wrestled and then got into a wrestling match, which led to a disagreement. Boy and his companions were told to leave, but Boy refused. Boy’s companions pulled Boy from the residence, and as they were walking away, Boy turned around and began to engage with Doe. Boy walked toward Doe, who was backing up, and stabbed Doe several times in the shoulder and back areas. Doe was flown to a Great Falls hospital for treatment of injuries.

In the second assault, the government alleged that on March 22, 2023, Boy and others were drinking alcohol and driving around when they drove toward East Glacier. The victim, identified as John Doe 2, was reclined in the front passenger seat and fell asleep. Another passenger told Boy that Doe 2 would assault her later and this may have initiated the assault on the victim. Boy stopped the vehicle in the middle of an intersection and began assaulting Doe 2, striking him repeatedly in the face and causing serious injuries. Doe 2 ultimately was flown to a Great Falls hospital for treatment of injuries.

Assistant U.S. Attorney Kalah A. Paisley prosecuted the cases. The Bureau of Indian Affairs, FBI and Blackfeet Law Enforcement Services conducted the investigations.
