GREAT FALLS – A Harlem man who sexually abused a minor on the Fort Belknap Indian Reservation was sentenced today to 24 months in prison, followed by 5 years of supervised release, U.S. Attorney Kurt Alme said.
Ivan Daniel Raining Bird, 35, pleaded guilty in September 2025 to one count of sexual abuse of a minor.
Chief U.S. District Judge Brian M. Morris presided.
The government alleged in court documents that John Doe was about 13 years old when he received a Facebook Message from a user who went by “Ivey” and appeared to be a woman. “Ivey” turned out to be the defendant, Ivan Raining Bird, who was in his late 20s at the time. Doe and Raining Bird continued to message, and Raining Bird eventually invited Doe over to his house.
When Doe arrived at Raining Bird’s house, he realized Raining Bird was a man dressed as a woman. Doe and Raining Bird shared substances and Raining Bird performed oral sex on Doe. For several months, Raining Bird committed similar assaults on Doe.
The FBI investigated Doe’s disclosure of the abuse and interviewed Raining Bird. Raining Bird admitted sharing drugs with teenagers in the past and specifically admitted he knew John Doe was a minor and sexually assaulted him on multiple occasions.
The U.S. Attorney’s Office prosecuted the case. The FBI and Fort Belknap Law Enforcement Services conducted the investigation.
