Believed to be about 8,000 years old, two US kayakers recovered the human skull last September in a river about 110 miles west of Minneapolis. After they spotted the unnatural shaped object on a riverbank, they paddled toward it. On realizing what it was, and suspecting it might belong to a modern murder victim, they called the Renville County Sheriff’s Office and reported the body part to Sheriff Scott Hable.
Sheriff Hable sent the skull to a medical examiner who then forwarded it to a Federal Bureau of Investigation forensic anthropologist . A report in the New York Times explained that preliminary testing determined the bone belonged to a young man who lived as many as “8,000 years ago, between 5500 and 6000 BC.”
