Isaiah Shawn-Sam Glenn, 30, pleaded guilty in April 2026 to one count of assault resulting in substantial bodily injury to a dating or intimate partner.
U.S. District Judge Susan P. Watters presided.
The government alleged in court documents that Glenn assaulted his girlfriend while the two were arguing in his vehicle in Lodge Grass on Sept. 21, 2025. Big Horn County Sheriff’s deputies arrived and spoke with the victim, who said Glenn struck her multiple times. She was treated by EMTs and taken to an area hospital, where she was diagnosed with multiple injuries, including bilateral bruising on her neck and scratches on her face.
The U.S. Attorney’s Office prosecuted the case. The FBI conducted the investigation.
