Lame Deer man admits assaulting partner on Northern Cheyenne Indian Reservation

BILLINGS — A Lame Deer man accused of assaulting a woman on two separate occasions on the Northern Cheyenne Indian Reservation admitted to multiple crimes today, U.S. Attorney Jesse Laslovich said.

Curtis Leo Crazymule, 45, pleaded guilty to assault of a dating partner resulting in substantial bodily injury, assault of a dating partner by strangulation and assault with a dangerous weapon. Crazymule faces a maximum of 10 years of imprisonment, a $250,000 fine and three years of supervised release.

U.S. Magistrate Judge Timothy J. Cavan presided. A sentencing date will be set before U.S. District Judge Susan P. Watters. The court will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors. Crazymule was detained pending further proceedings.

The government alleged in court documents that Crazymule and the victim, identified as Jane Doe, were in a romantic relationship when, in December 2022, Crazymule assaulted the victim while in a parked vehicle when she wanted to drive because of his level of intoxication. Crazymule headbutted, bit and strangled the victim, causing her to almost lose consciousness. The Bureau of Indian Affairs police responded, and the victim was transported by ambulance to a clinic in Lame Deer for treatment of injuries. In a second assault in January 2023, the government alleged that Crazymule assaulted Jane Doe at a residence with a baton, striking her on the head and knocking her unconscious. Two persons witnessed the assault. Crazymule denied striking the victim with a baton or any other object.

Assistant U.S. Attorney Lori Harper Suek is prosecuting the case. The Bureau of Indian Affairs, FBI and Indian Health Service conducted the investigation.
