Will Thomas and David Deacy were wading in the Columbia River near Kennewick, Washington, hoping to get a better view of a hydroplane race. Thomas’s foot struck a round object. He picked up a human skull. The discovery that day, July 28, 1996, would pull a 9,000-year-old man into a modern courtroom.
The nearly complete skeleton, soon called Kennewick Man, possessed a narrow face and a projectile point embedded in his hip. Initial forensic analysis suggested Caucasian features, a conclusion that ignited immediate controversy. It contradicted established theories about the peopling of the Americas, which held that early migrants from Asia were the sole ancestors of contemporary Native American tribes. The Umatilla and other local tribes, citing the Native American Graves Protection and Repatriation Act, claimed the remains for reburial. A group of eight anthropologists sued the federal government to block repatriation and allow study.
The legal battle lasted eight years. Scientists argued the skeleton’s age and morphological differences placed it outside any direct lineage to modern tribes. Tribal leaders argued their oral histories spoke of being in the land since time immemorial, and that scientific curiosity was a violation of their ancestor. The courts eventually sided with the scientists, permitting extensive study.
Advanced genetic testing in 2015 provided a definitive answer. Kennewick Man’s DNA showed he was most closely related to modern Native Americans, specifically the Confederated Tribes of the Colville Reservation. The initial morphological interpretations were misleading. In 2017, his remains were repatriated and reburied. The case transformed archaeological practice, forcing a difficult, ongoing reconciliation between empirical science and indigenous sovereignty.
