Box Elder man sentenced to prison for assaulting and strangling partner on Rocky Boy’s Indian Reservation

GREAT FALLS — Alex George Deserly, 43, of Box Elder, was sentenced today after admitting to an assault charge for strangling a woman on the Rocky Boy’s Indian Reservation, U.S. Attorney Jesse Laslovich said.

Chief U.S. District Judge Brian M. Morris sentenced Deserly to 30 months in prison followed by 2 years of supervised release. The defendant pleaded guilty to assault resulting in substantial bodily injury to an intimate partner in April 2023. 

The government alleged in court documents that on June 25, 2022, medical personnel and law enforcement responded to the victim’s home for a report of a domestic assault. Deserly had left the home prior to the police arriving. The victim told law enforcement that she had confronted Deserly over messages she had seen and asked him how long he had been using methamphetamine. Deserly grabbed the victim, shoved her into a wall and strangled her. The victim tried to escape, but Deserly continued to assault and strangle her until he eventually stopped. The victim was treated for injuries.

Assistant U.S. Attorney Jessica A. Betley prosecuted the case, which was investigated by the Federal Bureau of Investigation and Rocky Boy’s Police Department.
