Abstract of Information Available

Based on the information available, human remains representing two individuals have been reasonably identified from two different locations. One associated funerary object has been identified.

On July 31, 2022, a single cranial bone was discovered on a sand bar in the Little Missouri River in Billings County, North Dakota. This was exposed by a significant flooding event and reported to the Billings County Sheriff's Department, who transferred custody to the Billings County Medical Examiner on August 3, 2022. The medical examiner determined the remains to be the parietal bone of an adult human predating the present time. No associated funerary objects were identified.

On October 19, 2024, a human cranium was discovered along a deep, heavily eroded ravine in McKenzie County, North Dakota. This was reported to the McKenzie County Sheriff's Department and was originally thought to be a modern forensics case. The Federal Bureau of Investigation (FBI) took custody of the remains and determined that the cranium belonged to a Native American, likely female, that predates the present time and is not a forensic matter. The one associated funerary object is a bone awl.
